Not My Grandma's Crumb Cake
Kimberly Bergmann • August 30, 2022
I must insist that this is not
my Grandma's Crumb Cake recipe
My love for crumb cake perhaps is found in my genetic makeup. Mix one part Italian with one park New Yorker and you get me a die hard lover of dense crumbs and a little bit of cake.
My Grandma Pellegrino had a tried and true simple recipe that I share above. While she baked with great gusto for any Catholic holiday the other days she still provided something sweet, lest I never fade away and starve to death. Crumb cake was a staple in her house. Perhaps she did it for me? She was diabetic, so one doesn't really know. All of that to say my Grandma trusted her cake batter to Duncan Hines. Not Betty Crocker, Not Pillsbury, Duncan Hines. The crumbs were all her own.
As I got older and began to sample this treat at local bakeries I discovered a crumb dense cake at my favorite local bakery Create-a-cake in Port Jefferson NY.
When my family moved to North Carolina I suffered through crumb cake withdrawal. I still had Grandma's trusted recipe in my pocket so I forged forward changing up the crumb recipe to make it my own.
Suddenly I found that "Make Crumb Cake" was repeatedly on my Trinity Commercial Cleaning Task task list (thank you Brian), along with invitations to visit provided I bring a crumb cake.
Don't feel bad for me, I am happy to bring a little bit of my beloved Grandma where ever I go.
In my quest for the perfect crumb, I stumbled on a recipe that was perfected by Cook’s Illustrated. It is super easy and made me step out of my box cake into a "from scratch recipe". I still resort back from time to time but this recipe is fantastic and I’m so excited to share it with you today! No more searching Mooresville bakeries, we have you covered. Now if you need the crumbs cleaned up afterwords we at Trinity Commercial Cleaning are here for that too! You need only call.
For me it is all about the crumbs.
Is there such a thing as TOO MANY CRUMBS?
HOW TO MAKE CRUMB CAKE
There’s no big secret to making a great crumb cake wether using a box cake or from scratch.
But, there’s a little trick in how to create the perfect crumb topping.
To make this cake, you’ll start by making the crumb topping. Once you mix the crumb topping together, it’s going to look a bit dry. This is how it should look so trust the process. If you add more butter it will lend to crisper crumbs. Put the butter down!
Then you’ll mix up the batter of butter, sugar, eggs, vanilla, cake flour, salt, baking soda, and liquid buttermilk. The cake flour is necessary here instead of all-purpose flour to make the cake super soft and tender.
Once you’ve got the batter in the baking pan, you’ll start to crumble the crumb mixture on top. Gradually work your way around the edges and make your way to finish with the last of the crumbs in the center. THIS IS THE TRICK!
This trick will prevent the heavy crumbs from sinking into the light cake when the cake bakes. It will also ensure that the crumbs are evenly distributed across the top of the cake.
It works EVERY time!!
INGREDIENTS
FOR THE CRUMB TOPPING:
- ⅓ cup granulated sugar (2 ⅔ oz)
- ⅓ cup dark brown sugar (2 ⅔ oz)
- ¾ tsp ground cinnamon
- ⅛ tsp table salt
- 8 tbsp unsalted butter (1 stick or 4 oz), melted and still warm
- 1 ¾ cups cake flour (7 oz) (see Note #1 below)
FOR THE CAKE:
- 1 ¼ cups cake flour (5 oz)
- ½ cup granulated sugar (3 ½ oz)
- ¼ tsp baking soda
- ¼ tsp table salt
- 6 tbsp unsalted butter (¾ stick or 3 oz), cut into 6 pieces, softened but still cool
- 1 large egg
- 1 large egg yolk
- 1 tsp pure vanilla extract
- ⅓ cup liquid buttermilk (not dried buttermilk powder)
- Confectioners’ sugar for dusting
INSTRUCTIONS
- To make the topping: Whisk sugars, cinnamon, salt, and butter in medium bowl to combine. Add flour and stir with rubber spatula or wooden spoon until mixture resembles thick, cohesive dough; set aside to cool to room temperature, 10 to 15 minutes.
- To make the cake: Adjust oven rack to upper-middle position and heat oven to 325° F. Cut 16-inch length parchment paper or aluminum foil and fold lengthwise to 7-inch width. Spray 8-inch square baking dish with nonstick cooking spray and fit parchment into dish, pushing it into corners and up sides; allow excess to overhang edges of dish.
- In bowl of standing mixer fitted with paddle attachment, mix flour, sugar, baking soda, and salt on low speed to combine. With mixer running at low speed, add butter one piece at a time; continue beating until mixture resembles moist crumbs, with no visible butter chunks remaining, 1 to 2 minutes. Add egg, yolk, vanilla, and buttermilk; beat on medium-high speed until light and fluffy, about 1 minute, scraping once if necessary.
- Transfer batter to baking pan; using rubber spatula, spread batter into even layer. Break apart crumb topping into large pea-sized pieces between your thumb, pointer, and middle fingers and spread in even layer over batter, beginning with edges and then working toward center.
- Bake until crumbs are golden and wooden skewer inserted into center of cake comes out clean, 35 to 40 minutes. Cool on wire rack at least 30 minutes. Remove cake from pan by lifting parchment overhang. Dust with confectioners’ sugar just before serving.
NOTES
- If you don't have cake flour, you can make your own. You'll need a total of 3 cups of cake flour for the crumb topping and the cake. So, make the cake flour first and then divide it up for the called-for amounts in the crumb topping and cake recipes. To do this, remove 9 tablespoons of all-purpose flour and replace it with 9 tablespoons of cornstarch. Then, sift it together 5 times before dividing it up.
- It's important to take your time when adding the crumb topping to the top of the batter. Start at the edges and work your way towards the center. This will help prevent the crumbs from sinking into the cake since the heaviest part of the batter (the center) will have some lift by the time you get there. And whatever you do, don't pat the crumbs down - you'll push the air out of the batter and prevent the cake from rising.

Medical cleaning services go beyond surface-level cleaning... They involve specialized protocols, hospital-grade disinfectants, and precision handled by trained professionals. Keeping a medical facility safe requires more than basic janitorial work. Medical-grade disinfection is a science-based cleaning process designed to eliminate pathogens, protect patients and staff, and maintain regulatory compliance. Many assume that “deep cleaning” or routine wiping is enough, but healthcare facility cleaning demands trained experts who understand chemistry, safety procedures, and infection-control systems. Here’s why medical office cleaning services must be performed by professional disinfection technicians — not untrained staff. 1. Why Medical Facilities Require Precision Disinfection by Professionals. Healthcare settings experience constant movement between patients, staff, and visitors — increasing exposure to infectious pathogens. Professional disinfection technicians understand: Which disinfectants are EPA-approved for medical environments Correct dwell times (how long disinfectants must stay wet to work) High-risk touchpoints that require enhanced disinfection The workflow order needed to prevent cross-contamination Without precision cleaning systems, microbes remain and infections spread — especially in clinics, surgical suites, urgent care, and dental facilities. 2. Medical-Grade Disinfection Requires Proper Use of Hospital-Grade Chemicals Medical disinfectants are more powerful and regulated than standard commercial products. These disinfectants target pathogens such as: MRSA C. diff spores bloodborne pathogens airborne viruses Improper mixing or technique can be ineffective — or even hazardous. Professional medical cleaning services ensure: Safe handling of chemical concentrations Correct dilution ratios Proper dwell time Compatibility with medical equipment Reduced risk to patients, staff, and visitors This safety expertise is essential for healthcare facility cleaning and compliance. 3. Professional Medical Cleaning Services Use Specialized Disinfection Equipment Medical facilities require disinfection coverage beyond what traditional spray-and-wipe methods can achieve. Professionals use technology designed for infection prevention cleaning, including: Electrostatic sprayers for complete 360° coverage HEPA filtration vacuums ATP surface testing to verify cleanliness High-touchpoint mapping systems This equipment improves consistency, reduces human error, and supports clinical-grade sanitization standards. 4. Professional Disinfection Protects Patients, Staff, and Facility Reputation One missed step puts everyone at risk. Improper disinfection can lead to: higher infection transmission employee illness legal or regulatory exposure loss of patient confidence Hiring a hospital cleaning company ensures safety and compliance through trained protocols. Your reputation depends on consistent, documented infection-prevention practices.

Understanding the science, systems & safety standards behind true clinical-grade cleanliness When most people think of “clean,” they imagine: Dust-free desks Empty trash bins Shiny floors But in healthcare facilities, “clean” isn’t about appearance—it’s about protection, compliance, and infection prevention at the microbial level. Medical cleaning services must follow standards that go far beyond routine janitorial work. Doctor’s offices, dental practices, urgent care facilities, surgical suites, and outpatient centers require cleaning protocols shaped by science and regulatory expectations—not just aesthetics. This guide explains: What medical cleaning services include Why healthcare facility cleaning is different from standard office cleaning The science behind disinfection and infection control What pathogens cleaners are trained to remove How cross-contamination happens What to look for in a qualified cleaning partner These insights answer commonly searched questions like: “What does medical office cleaning include?” “Why does medical cleaning matter?” “How clean should a healthcare facility be?” “What is clinical-grade cleaning?” 1. Why Medical Facility Cleaning Is Different from Standard Cleaning In a commercial office, cleanliness means organized, fresh, and presentable. In healthcare environments, “clean” must include reducing microbial risk and protecting immunocompromised patients. Medical cleaning services address unique challenges such as: Cross-contamination risks Bodily fluids and biohazards Sick patients entering and exiting Regulated sanitization requirements (CDC, OSHA, GBAC) High-risk, high-touch surfaces A surface can look spotless but still carry infectious microorganisms. The primary goal: Remove pathogens before they spread Break the chain of infection Protect patients, visitors, and staff In healthcare, clean isn’t what you see—it's what you remove. 2. Cleaning vs. Sanitizing vs. Disinfecting in Medical Environments These terms are often confused, but in clinical settings the differences matter. Cleaning Removes dirt and debris Uses soap or detergents Does not kill germs Essential first step before disinfection Sanitizing Reduces bacteria to public health safe levels More common in food service Not strong enough for most medical environments Disinfecting Kills 99.9% of viruses, bacteria & fungi Uses EPA-registered disinfectants Required for high-touch surfaces Disinfection only works when applied with: Correct product Correct technique Correct dwell time (required wet contact duration) Skipping dwell time is the #1 reason non-medical cleaners leave pathogens behind. 3. What’s Included in Medical Cleaning Services? Routine medical cleaning services focus on infection prevention through: Disinfection of high-touch surfaces Waiting room + reception sanitization Restroom + exam room cleaning Biohazard & bodily fluid protocols Microfiber + color-coded cleaning systems HEPA filtration vacuuming PPE use + clean-to-dirty workflow Digital reporting & documentation Proper chemical handling + dilution ratios These systems ensure healthcare facility cleaning improves safety, not risk. 4. High-Touch Surfaces: Where Microbes Spread Most Medical cleaners prioritize the highest-risk surfaces, including: Door handles + push plates Bed rails + exam tables Touchscreens + keyboards Nurse stations + supply carts Light switches Medical equipment Waiting room furniture Restroom fixtures Even when they “look” clean, pathogens may remain—especially after sick patient contact. 5. Preventing Cross-Contamination in Healthcare Cleaning Cross-contamination happens when microbes spread between rooms or surfaces through: Dirty microfiber towels Improper glove use Used mop water Incorrect cleaning order Shared equipment Professional medical cleaning services follow strict systems: Color-coded microfiber Single-use disinfecting wipes in high-risk areas Fresh mop heads + solution per room Clean-to-dirty workflow HEPA vacuums Proper PPE These controls protect patients and staff by preventing pathogens from “hitchhiking” through a facility. 6. What Medical Cleaners Are Actually Removing Healthcare environments must be cleaned assuming pathogens are present, including: MRSA Influenza Norovirus COVID-19 E. coli C. diff (requires specialized disinfectants) Bloodborne pathogens General cleaning companies are not trained for this. Healthcare facility cleaning requires specialized training aligned with: OSHA CDC GBAC protocols 7. The Microbiome Factor: Why Restrooms Matter Restrooms influence the microbiome of an entire healthcare facility. Commercial toilets flush with higher pressure, creating aerosolized droplets—known as a “fecal plume”—that can: Travel beyond restroom surfaces Become airborne Spread bacteriophages Contaminate adjacent areas Bioluminescence testing reveals plume spread across floors, doors, and counters. This makes restroom cleaning vital for infection prevention and indoor environmental health. Healthcare restrooms require: Hospital-grade disinfectants Frequent high-touch disinfection Proper ventilation Color-coded tools Strict cross-contamination prevention 8. Dwell Time: The Most Overlooked Factor in Medical Disinfection Every EPA disinfectant requires a contact time—often 1–10 minutes. If the product dries early or is wiped too soon, it fails to kill pathogens. Professional medical cleaners: Read EPA labels Use proper coverage Keep surfaces visibly wet Apply appropriate dwell time If a cleaning company can’t explain dwell time, they shouldn’t service healthcare facilities. 9. Appearance Still Matters in Medical Spaces While microbial safety is the priority, visual cleanliness impacts perception. Patients and staff expect medical spaces to look clean: Spot-free glass and floors Organized counter spaces Clean restrooms Sanitized waiting areas A visually clean environment promotes: Patient trust Positive reviews Staff morale Regulatory confidence 10. How to Know Your Medical Cleaning Partner Is Qualified Look for signs of true medical cleaning expertise: ✔ Written cleaning protocols ✔ Staff trained in OSHA + CDC guidelines ✔ EPA-registered disinfectants ✔ Microfiber + color-coding ✔ No reused mop water ✔ Documented high-touch procedures ✔ Dwell time knowledge ✔ Digital checklists or reporting ✔ Custom plans for each facility If a provider can’t explain their system, they likely don’t have one. Medical Cleaning Services Protect Patients, Providers & Reputation Medical cleaning isn’t routine janitorial work—it is infection prevention and regulatory compliance. A properly cleaned facility is one where: Pathogens are eliminated Cross-contamination is reduced The chain of infection stays broken Staff work confidently Patients feel safe Healthcare environments deserve cleaning rooted in science—not guesswork.
