New York Chocolate Crumb Cake

I love a good crumb cake and this Chocolate Crumb Cake is a new favorite! It is great for breakfast or dessert! The best part about this cake is that it is super easy to make. I cheated and used a box of cake mix for the base of the crumb cake. Once the cake was mixed up, I topped it with a quick and easy homemade chocolate crumb topping. The cake was ready for the oven before the oven was preheated!

How to Make Chocolate Crumb Cake with Cake Mix

This cake is easy to make with only a few simple ingredients. Grease and flour a 9×13-inch cake pan. In a large bowl, combine chocolate cake mix, eggs, water, and oil. Use a mixer and mix until well combined. Pour cake batter into the prepared pan. 

In a medium bowl, combine granulated sugar, brown sugar, salt, unsweetened cocoa powder, cinnamon, melted butter, and all-purpose flour. Mix with a mixer or stir by hand until combined and crumbly.

Stating at the edges of the pan, sprinkle crumb mixture over the cake and work your way towards the center. Bake in a preheated oven. Remove the cake from the oven and cool on a wire rack.

Helpful Tips and Frequently Asked Questions

  • Make sure to cover the entire top of the cake batter with the crumb topping layer.
    • If you don’t cover the cake completely, the cake batter will bubble up through the crumb topping.
  • Line the cake pan with parchment paper to easily remove the cake from the pan.
  • Top the cooled cake with powdered sugar or a quick powdered sugar glaze.
  • The cake can be made a day or two in advance and stored in an airtight container.
