How to make Chocolate Cinnamon Crumb Cake

This chocolate cinnamon crumb cake is really easy to make, and doesn’t need any fancy baking skills. Just a couple of bowls and a small food processor. Here’s what you have to do:

Whisk all wet ingredients in a bowl – Hot water, applesauce, lemon juice, melted butter vanilla extract.
Use hot water – it’s needed!
Use melted butter so that it mixes well into the healthy chocolate crumb coffee cake batter.

Whisk dry ingredients – flour, coconut flour, chocolate protein powder, unflavored protein powder, cocoa powder and baking soda.

Add dry mix to wet; Whisk until just combined.
Don’t over-mix or cake will get tough!

Taste the batter and see if you need some extra sweetener.
Use stevia powder to maintain the consistency of the batter and have healthy, sugar free chocolate protein cake.

Make Streusel topping on Chocolate Protein Cake:

Combine ingredients in a small food processor – flour, brown sugar, cinnamon and cold butter. Use cold butter, so that you get a crumbly streusel and not melty butter.

Process until crumbles just form!
Over-processing will make the butter melt

Assemble and Bake:

Pour batter into baking pan.
Add sprinkle streusel on top.

Bake for 25-30 mins.

Stop baking when tester/knife comes out just dry, but moist.
Don’t over-bake the cake or it will get tough.

Icing:

Let cake cool before icing or the icing will melt.

Whisk powdered sugar and milk.

Don’t add too much milk in the icing; It will come together quickly.

Store chocolate coffee cake (once cooled) in an airtight container. It should keep on the countertop for 1-2 days or in the fridge for upto 4 days or freezer for 2-3 months. Don’t forget to thaw frozen cake before eating.
