Crumb Cake – A Childhood Favorite
Growing up in New Jersey, I loved cakes like Entenmann’s Crumb Coffee Cake and Crumb Buns from the local bakery. I have a weakness for anything with a crumb topping!
On Sunday mornings, my parents always had fresh rolls and crumb cake from the bakery. The best was when it would still be warm!
Food can really remind you of home, but when I lived in England, crumb cake wasn’t sold there, which forced me to try to recreate this beloved favorite.
The good news – this Jersey Girl can bake! This is my version of the Entenmann’s cake of my childhood. I warn you – it’s addictive!
Why This Recipe Works
- The brown sugar in the topping adds depth of flavor and keeps the topping from becoming too crispy.
- The extra baking powder in the cake ensures the topping won’t sink into the cake.
- The buttermilk lends flavor as well as moisture to the cake.
How To Make Cake Crumbs
To make the cake crumbs, start with adding flour, brown sugar, cinnamon, and salt to a mixing bowl.
Mix well and pour in warm, melted butter. Stir to combine.
At this point, I press the mixture into balls. This not only helps to crumble it over the cake, but it also lets me know if more butter is needed.
If the balls don’t stay together you know to add more butter to the mixture.

Transfer batter to prepared baking pan (The batter will be thick); spreading it evenly over the pan.

Bake until the tester comes out clean and topping is a deep golden brown. 
Cool cake completely and dust with powdered sugar.
Serve and enjoy every last bite.
Baker’s Tips:
- Make the topping first. Leaving the batter to sit before baking may cause problems with rising, causing the topping to sink into the cake.
- Use good quality unbleached flour for the best result. lower quality flour may not have the stability to hold the topping.
- Don’t overmix the batter once the flour is added. Overmixing can cause a tough, dense cake.
- Be sure to cool the cake completely before dusting with the sugar. A warm cake will melt the sugar.

Just finished grabbing my first bite of this cake, a corner piece. While the crumbs stayed on top, they are thicker than the cake. Even looking over the video, it would seem I had a lot more crumb topping than the video.i cooked in a 9×13 clear glass pan for 55minutes in a convection oven. I’m thinking the cake is slightly under cooked (making my wife happy),but I think I would have liked more cake than crumb. I thought about not using all the crumb stuff but just went ahead. Did the cake “not rise” because of the crumb topping? Tastes good, I’m shaking a little because of all the topping I had! Will try again.

Glad you still enjoyed it Jerry, cakes can be tricky, not all ovens cook them the same. I hope you perfect it next time, it’s totally worth it!
Jerrt says
Thank you for the recipe. Can I increase the cake recipe by 50% to make it thicker or possibly just use a smaller pan- which then leads to the question of cooking time and whether I also need to change the temperature? Any suggestion would be appreciated.
Erren Hart says
Hi, on the recipe you can change the number of serving and it will give you the new measurements. As far as changing the pan, I’d need the pan size to help.
Lorre says
This recipe is great! My question: I wanted to use it to make as muffins. Do you think that will work? Any suggestions for changes to the recipe? I’m thinking 18-20 mi urea baking time? Thanks for the help.
Erren's Kitchen says
Hi Lorre, I think that’s a great idea, I would say between 15 and 20 minutes, but it may be a case of trial and error. Good luck 🙂

I’m really enjoying the design and layout of your website.
It’s very easy on the eyes which makes it much more enjoyable for me
to come here and visit more often. Did you hire out a designer to create your theme?
Cheers

Mary Ann Asciutto says
Just made the cake according to your directions and my crumbs sunk into cake. What did i do wrong? I made the topping first like instructed.
Erren Hart says
Hi Mary, What type of flour did you use? I find some brands of flour are very light. Next time, try adding a half cup of bread flour to add stability.
PS Bobby says
I followed the recipe to a T. The cake rose so high it bubbled up covering the crumbs.
The one I made from ATK’s video came out perfect but wanted to give a Jersey girl a chance. 😢
Erren's Kitchen says
Oh I’m sorry this didn’t work out for you. There were some issues with our conversions (that have now been rectified) so I hope you’ll try it again. Thank you for the heads up.
Valerie says
