Cinnamon Crumb Cake
This post may contain affiliate links. Please read our disclosure policy.
The irresistible, extra thick, cinnamon brown sugar crumb topping is just the beginning of this fun-to-eat New York style Cinnamon Crumb Cake.
I’ve more than doubled the thickness of the buttery crumb topping. I didn’t want just a small crumb, so you’ll be happy with the generous crumb on this recipe. I also made it a point to create a super moist, melt-in-your mouth cake layer. It has just the right amount of butter, vanilla, sour cream and sweetness to get you craving more of this crumb cake.
I found using a 9×9 inch cake pan was the best for this recipe. I used an aluminized, non-stick pan, not glass. The size of the pan to get the perfect height of the crumb and cake is just as important as balancing out the ingredients to get the perfect size to the crumb, crumble and crumb to cake ratio! Note: this recipe was tested in an 8×8 inch pan, but overflowed in the pan and the middle did not cook through.
I really wanted a moist cake layer and a thick crumb layer for this recipe. There is just nothing worse than a dry, crumbly cake in my opinion! I’ve worked out all the kinks, so you don’t have to, to make the most delicious Cinnamon Crumb Cake.

Table Talk with Tawnie
In 2023, a reader emailed me asking to recreate a New York Style Crumb Cake. I get a lot of requests for different recipes, but this one was one I really wanted to tackle. Three years later, this recipe is one of the most popular recipes on Kroll’s Korner! I mean how can you resist that incredible ratio of crumb to cake?! Just look at these photos, I can’t stop staring at it! LOL. My recipe is reliable, delicious, and perfect for weekend baking, I know you’ll love it! 🤗
Reasons To Love My Cinnamon Crumb Cake
- It’s a great crowd-pleasing dessert.
- It’s the perfect treat for breakfast, brunch, served with coffee, or after dinner with scoop of ice cream.
- It is soooo easy to make!
- It is so moist that if you have stored it properly, it will be just as moist 2 to 3 days after baking!
What is the difference between crumb cake and coffee cake?
The biggest difference between crumb cake and coffee cake is the crumb. With Crumb Cake, the crumb is bigger and you have so much more crumb that you can pick off the large chunks of crumb and pop them in your mouth (it’s like getting two desserts in one). On a Coffee Cake, the crumb size is much smaller so you can’t really pick off the crumb. Since we have so much more crumb on a crumb cake, there is more sugar in the recipe, so the crumb cake is sweeter than the coffee cake.
Ingredient Notes
(For the full recipe, scroll down to the recipe card below)
- Cake flour: If you know me you know I love baking with cake flour. Especially for this recipe. Using cake flour will create soft and tender cakes.
- Baking powder: This lightens the texture of the cake by enlarging the bubbles in the cake batter.
- Baking soda: Interacts with acids in the recipe creating carbon dioxide which creates bubbles. These bubbles cause the batter to rise.
- Cinnamon: gotta have some cinnamon in a Cinnamon Crumb Cake!
- Kosher salt: The fine grain of Kosher salt is great for baking, because it disperses quickly into ingredients
- Unsalted butter: Room temperature to mix together easily. The butter in the crumb topping will be melted.
- Eggs: room temperature so they mix more evenly into the cake.
- Sour cream: the creamy texture of sour cream makes the cake more moist than if you just used milk. I haven’t tested this recipe with Greek yogurt but I think that would be a fine substitution.
- Whole milk: the purpose of using whole milk is that the fat content makes the cake more moist, so it is always best to use whole milk when a recipe calls for milk.
- Vegetable oil: The cake will be loftier, will have more of a crumb, and will be more moist. This was something I added into the cake after a few rounds of testing to really help with the moist texture!
- Confectioners sugar for topping: A light dusting adds the finishing touch to this delicious cake.
Step by Step Directions
(For the full recipe, scroll down to the recipe card below)
Make the Crumb Topping
In a bowl, whisk together 1 ½ cups flour, brown sugar, granulated sugar, cinnamon, and salt. Pour in the melted butter and mix until combined. Add in the remaining 1 cup flour and use your hands to form large, chunky crumbles. Set aside.
Prep the Dry Ingredients
In a separate bowl, whisk together the cake flour, baking powder, baking soda, cinnamon, and salt. Set aside.
Cream Butter & Add Wet Ingredients
In a stand mixer, cream the butter and sugar until light and fluffy, about 3 minutes. Add the eggs, then mix in the sour cream, milk, oil, and vanilla. (It may look a little curdled—totally normal!)
Combine & Spread the Batter
Add the dry ingredients to the wet ingredients and mix until just combined. The batter will be thick. Spread evenly into a prepared 9×9 pan and gently tap to release air bubbles.
Top, Bake, Cool, & Enjoy!
Sprinkle the crumb topping evenly over the batter, keeping those big crumbles intact. Bake at 325°F for 45–50 minutes, or until a toothpick comes out clean. Cool completely, dust with powdered sugar, slice, and enjoy!
Tips and Variations
- Make sure all your ingredients are at room temperature so they will mix easily and quickly.
- It’s important to measure your flour accurately.
- Make sure your brown sugar for the crumb topping is soft and moist.
- When mixing in the dry ingredients, be sure to keep the mixer on low speed.
- Careful not to over mix the crumb topping or the cake batter.
- There are so many options when it comes to customizing your crumb cake: Raspberry, blueberry, apple, peanut butter, chocolate, or salted caramel.
- When adding the crumb topping gently press the topping on top of the batter just so it sticks.
- For the perfect soft and moist crumb cake do not over bake.
FAQs
Why is my crumb topping soggy?
This often happens if the crumb topping is over mixed or the melted butter was too hot when you mixed it in.
How long does crumb cake stay fresh?
Stored in an air tight container on the counter, it will stay fresh for 2 – 3 days.
Can I freeze crumb cake?
Yes, my Cinnamon Crumb Cake recipe is freezer friendly. Just wrap it once it has cooled and store in an air tight container and pop it in the freezer for up to 2 months.
Can I bake it in a 9×13 pan?
I haven’t tested this recipe in a 9×13 inch pan. But, I am sure it would work, they cake and crumb would just be thinner and you would need less bake time. I did test this recipe in an 8×8 inch pan and it overflowed, so I wouldn’t recommend that.
What type of pan should I use?
I found using a 9×9 inch cake pan was the best for this recipe. I used an aluminized, non-stick pan, not glass. This recipe has not been tested in a glass pan. If using glass, the bake time will be longer.

This was exactly what I had hoped it would be. I’ve made New York Style Crumb Cake before and loved it. But this recipe sounded a little more indulgent! I followed the recipe precisely and it met my expectations! Cudos.
Dawww, well thank you Arthur!! I am so happy this is what you were looking for and that you enjoyed it!! Hope you find other new fave recipes on my site too! 🫶🏻
I have been making banana bread for over 20 years and this is by far the best recipe EVER! This will be my new go to! I made it in a tube pan .. sooooo delicious!!!
So glad you liked this recipe! Thank you 🙂
Whelp! It seems I’m not as careful as I’d think. While I was distracted and making dinner at the same time as this beautiful crumb cake, I missed (A) the TEMPERATURE and the (B) pan size. I grabbed my trusty 8×8 (I do actually have a 9×9!) and made this superb cake. Nice big crumb texture and excellent crumbly topping just like you’d find in any east coast dinner and many coffee shops. Another solid win!
haha! Still looks incredible – thank you so much!!
The cinnamon crumb cake was so easy to follow and came our delicious! I will definitely be using and following more recipes!
So happy you enjoyed it, thank you!!
Did you find you had to cook it longer than the time posted ? Mine has been in 50 min at 325 and still not cooked
Ovens can vary. So sorry about that! What type of pan are you baking in? How long did you end up baking it for? I hope you enjoyed it!! 🙂
Mine is doing the same! Currently at 60 minutes and it is still raw in the middle.
Oh no, I’m sorry to hear that! Ovens can vary so much which is maddening. What type of pan are you baking in? That could be another factor…
So yummy!! The cake is super fluffy and crumb topping, delicious! I used the 1/2 recipe and baked in an 8×8 pan. Worked perfectly! This recipe is definitely a keeper!
Thank you so much, Teresa!! I’m so glad you loved it! 🫶🏻
Look the corner of the recipe and make the 1/2 recipe and it will fit an 8×8 pan.
Made this for the holiday challenge. I only had a8x8 pan which didn’t fit all the batter and crumb so it spilled out but other than that it was delicious!
So tasty!!! Mine came out a little raw in the center, but that did not stop me from devouring it! It’s not overly sweet which I love and goes great with morning coffee 🙂
I used a bundt cake pan because I didn’t have a 9×9. I highly recommend using the 9×9 per recipe instructions! This crumb cake was moist and delicious. The crumble was fantastic! So much crumb topping!
Yay! Thank you Kim!
I used this recipe for a birthday cake for my dad and he loved it! I baked it in a round pan and added homemade strawberry sauce to decorate it. So good!
