Gluten Free Shortcut Crumb Cake
Betty Crocker gluten free yellow cake mix
2 sticks unsalted butter
2 C. Betty Crocker gluten free flour blend
1 C. sugar
1 Tbsp. cinnamon
Preheat oven to 350 degrees. Prepare the cake mix, according to package directions. Pour batter in a prepared 9x9 pan. Bake for 15-20 minutes. With a mixer, combine the butter, flour, sugar, and cinnamon into a crumbly mixture. Sprinkle all the crumbs over the cake and return to the oven for an additional 15-20 minutes. Let cool completely before cutting.
* If using a regular cake mix and regular all purpose flour, bake cake in a 9x13 prepared pan. The original recipe also had a double batch of the crumb topping. I cut it in half for my gluten free cake.
