If you're like me and like a good piece of coffee cake with your coffee...this one definitely rivals Starbucks! I only used 1 cake mix, but if you want a nice thick piece like you get at the coffee shop, double the recipe and use 1 - 9x13 pan and 1 - 8 x 8 pan - you'll need to adjust baking times and such...
Coffee House Coffee Cake
1 Box Yellow Cake Mix(plus ingredients listed on package)
1 Cup (2 Sticks) Butter, Cold/Chilled
2 1/4 Cups Flour
1 1/d Tbsp Cinnamon
1 3/4 Cups Brown Sugar
1 1/2 Tbsp Vanilla
Preheat oven to 350 degrees.
Mix cake mix according to package directions. Spray pan with non-stick spray. Pour batter into pan. Bake for 15-20 minutes - until center is just barely set.
While cake is baking, prepare crumb topping. In large bowl mix all ingredients with electric mixer until crumbly.
IMMEDIATELY after cake is removed from oven, break crumb topping into pieces with fingers and sprinkle over top. Put back in oven and bake an additional 15 minutes (topping will begin to look a little less wet/raw).
Let cool fully. Serve with a dusting of powdered sugar.
