Both a breakfast and dessert, my Crumb Cake stands out from the foil-lined, premade version you can buy at the grocery store. Perfectly dense, moist, and piled high with crumb topping, this simple recipe comes together quickly, and it’s big enough to feed a crowd! How-to video included in the recipe!
While some people confuse crumb cake for coffee cake, there’s actually a pretty big difference between the two. Traditionally, coffee cake is topped with a layer of crumbly streusel, while crumb cake is essentially half crumb, half cake. Both are worthy bakes, but today, we’re all about the crumb!
The key to getting the perfect, melt-in-your-mouth cake is a technique I’ve covered before called reverse creaming. While it may sound complicated, it’s actually very simple and yields a soft texture that lasts for days. Plus, unlike the traditional creaming method, you don’t have to worry about over-mixing.
If you’ve tried my Caramel Cake or Chantilly Cake, then you’ve already tasted the benefits of reverse creaming. Why not give it a try with my crumb cake as well?
What You Need
Here are some of the key ingredients in this simple recipe.
- Sugar. In addition to white sugar, we use both types of brown sugar in this recipe. The combination of white and light brown sugar in the batter helps keep things moist, and the dark brown sugar in the crumb adds that deeper, molasses flavor. Don’t have brown sugar on hand? See my tutorial on how to make brown sugar at home.
- Butter. Softened butter in the batter is reverse creamed to nail down that plush texture we all love, while melted butter in the crumb gives us that crumbly (buttery!), textured top that’s essential to crumb cake.
- Sour Cream. Sour cream is a secret weapon for keeping baked goods tender, plus it adds a subtle tang that balances sweetness. If you don’t have sour cream on hand, you can substitute plain, full-fat yogurt.
- Egg Yolk. You’ll notice that there is an extra egg yolk in this recipe. This adds to the tenderness of the crumb. We eliminate the extra white (which could actually dry out the crumb, we already have enough egg whites!) and just add an extra yolk which keeps the cake moist, soft, and melt-in-your-mouth.
- Cinnamon. I say this is optional, but you really should add it! Cinnamon provides warmth and sweetness, and it’s what makes the crumb so delicious. If you really must skip it, a pinch or two of nutmeg would also work.
SAM’S TIP: Make sure to use unsalted butter in both the cake and the crumb topping. We can better control the amount of salt in this recipe by adding it in ourselves.

How to Make Crumb Cake
As I mentioned above, the reverse creaming method is what gives this crumb cake its tight, plush texture. Don’t be intimidated by the name; reverse creaming is actually a very simple technique where, instead of first creaming together the butter and sugar, you gradually add the butter into the dry ingredients until you have a sandy mixture.
After that, things move pretty quickly from batter to crumb topping, which lucky for you, doesn’t even require a pastry blender.
- Combine dry ingredients and sugar in a bowl or the bowl of a stand mixer. Using either your stand mixer or an electric mixer, add the butter, one tablespoon at a time. Be sure to only add the next tablespoon when previous one has been fully incorporated. Once all of the butter has been added, the mixture will resemble coarse, sandy crumbs.
- Separately, whisk the sour cream, egg, egg yolk and vanilla extract until well-combined. Add this mixture your batter and stir until completely combined and silky. Pour that into your prepared pan while you make the crumb topping.
- Whisk together flour, sugars, salt, and cinnamon. Once combined, drizzle melted butter over the flour mixture and use a fork to toss the ingredients together until you have a clumpy crumble topping.
- Scatter crumb topping evenly over the batter in your pan and bake until a toothpick inserted in the center comes out clean or with a few moist crumbs.
SAM’S TIP: I always prefer to see a few moist crumbs rather than a clean toothpick. A clean toothpick means the cake is done, but it may be over-baked and as it cools it could become over-done and dry. Moist crumbs mean the cake is ever-so-slightly under-done and will finish baking as it cools, resulting in a super moist, soft cake.
Frequently Asked Questions
Crumb cake has a thicker layer of crumb. You can try my Cinnamon Coffee Cake to see which you prefer!
You can, but all-purpose flour works just fine. Keep in mind that if you choose to use cake flour you will need to substitute it properly.
Yes! Because we use the reverse creaming method, this crumb cake stays soft longer than most. It’s the perfect recipe to make for overnight guests!

Samantha
I followed the recipe exactly but ended up with very “sandy” crumbs. They were not clumpy at all. I wonder what i did wrong? It tastes amazing but the crumb texture is off!
Sam
Hi Samantha! A couple of things that could happen here, there may have been a little too much flour in the dough, your butter may not have quite been warm enough, or hopefully the easier solution here is it just needs to be mixed together a little bit longer. 🙂
Anna
The cake came out very delicious. Even my picky eater enjoyed it. I used some buttermilk in place of sour cream since I didn’t have enough sour cream and still came out perfect. I tried many of your recipes and they always come out delicious! ❤️
Emily @ Sugar Spun Run
We’re so happy it turned out for you, Anna! Enjoy 😊
pam kristiansen

Emily @ Sugar Spun Run
Thanks so much for trusting our recipes, Pam! ❤️
Kristi K Payne
Can you taste the sour cream in this
Sam
Hi Kristi! You won’t be able to taste the sour cream here. 🙂
pam kristiansen
Will do!
Pam
My mom used to buy a cream filled crumb cake that was amazing, is there a way to do that?
Emily @ Sugar Spun Run
Hi Pam! Unfortunately, without testing it out ourselves we’re not sure how adding a cream filling would work. If you try it out, will you let us know how it goes? We’ll add this to our list of recipes to perfect, because it sounds delicious! 🙂
Janet
I made this today, hands down, the BEST crumb cake I have ever made or had! So good! Directions were easy to follow and the cake came out perfectly. The topping is the best!
Sam
I am so happy to hear this, Janet! Thank you so much for trying my recipe and for letting me know how it turned out for you! 🙂
Eta
I baked this last night, followed the recipe to a Tee but the cake portion came out looking like firm custard or jelly after I cut through when it had cooled and yet the skewer came out clean. The crumb was perfect, wasn’t happy with the rest of the cake 😟 is there something I did wrong….
Sam
Hi Eta! That definitely sounds like the cake was not cooked through, though I am not sure why the skewer would come out clean. Next time I would bake a bit longer and maybe cut into the center with a knife and take a peek that way. I hope that helps!
Anna
I had exactly the same issue 😟. It was baked through, even a little too much, but the batter in the bottom looked as if it had „seperated“. Tasted good but looked strange.
GraceAnn
Oh My Gosh, this recipe is magnificent. I love it. When I ate it, I felt so good. I didn’t want to stop, Thank You for this.👍😀I love it, Sam!
Sam
I’m so glad you enjoyed it so much, GraceAnn! 🙂
Cheryl
This is really a rich buttery crumb cake. Very sweet. The recipe instructions were very good and easy to follow. Be sure you cut 16 slices because it is rich!
Simone
Baked it today. Delicious and it came out good. A bit too sweet for me so will cut sugar in half next time. Love the crunch of the crumb topping!
Gina
This is in my oven as I’m writing this.
This smells so good, and I cannot wait to try it! I added a lot of extra Vietnamese cinnamon, because I just love cinnamon, but that was my only addition.
Aiden Garcia
I don’t have a 9×9 pan on hand would an 11×7 or 8×8 be a good replacement out of the two?
Sam
Hi Aiden! An 8×8 should work here, just make sure to not overfill the pan and keep an eye on it as your bake time may change a bit. 🙂
Marcy
This looks really good—can I use a 9×13 inch pan? If so, how do I adjust accordingly?
Sam
Hi Marcy! You could use a 9 x 13 pan. If you don’t increase the recipe the cake will be pretty thin. You should be able to increase the recipe by 50% and have the same thickness. I’m not sure on a bake time though. 🙂
Heather H
I’m planning on making this since it looks so good and easy. I saw that instead of Sour cream, you recommended using full-fat plain yogurt. I was wondering if 0% fat greek yogurt can be used instead?
Sam
Hi Heather! I would be worried the cake would be a bit dry if you use the 0% yogurt.
Bitsie
This looks delicious, I can’t wait to try it out! How much butter is used in the cake in grammes? I want to make sure that I get it right. Thank you and congratulations on your expanding family!
Sam
Hi Bitsie! I just updated the recipe to make sure the butter had gram measurements as well. Enjoy, and thank you! 🙂
Bitsie
Thank you so much Sam, I shall bake this tomorrow and like all your recipes I am sure that it will be wonderful!
Judy
can I use a glass 9 x9 pan?
Sam
Hi Judy! That will work, but your baking time may differ a little bit. 🙂
Cheryl
Like the sound of this recipe—all ingredients I always have on hand, small pan for just the two of us and simple complete instructions. It’s a cool day so I can turn on my oven!
Sam
I hope everyone loves it, Cheryl! 🙂
AnnMarie Crisa
can you make these into cupcakes? if so how long to bake?
Sam
Hi AnnMarie! It could work but I’m not sure on a bake time. Enjoy! 🙂
