Blueberry Crumb Cake

This blueberry crumb cake is easy to make and has a streusel crumb topping.

This blueberry crumb cake is a variation of my Sour Cream Coffee Cake.  It has few alterations and it tastes great with the addition of blueberries.  It makes for a tasty breakfast or for a yummy dessert.

I made this crumb cake in a 9×13 baking dish.  I lined the dish with parchment paper because it makes for super easy cleanup! 

This cake has a layer of blueberries between two layers of the cake mix.  It has a streusel topping of cinnamon and nutmeg spices and is finished off with sprinkled blueberries.

Making a Moist Cake

The key to making a moist cake is in the technique of making it.  It’s important to not overbeat the mix for the cake and it’s important to not overbake it in the oven! 

Checking the cake with a toothpick in the center of the cake is the best way to tell if it is done.  If it comes out clean, take the cake out of the oven and let it cool on trivets.  Allow the cake to cool completely before adding the drizzle topping.
