Easy Starbucks Coffee Cake

I've tried a few copycat recipes for the starbucks coffee cake. this by far is the best and easiest that i have tried since the base starts with a boxed cake mix. i think it tastes pretty close to the real deal" and hope you enjoy it too!"!

Steps

Prepare cake mixe in large bowl according to directions on box.

Spray 9x13 pan with non-stick spray.

Pour batter into pan.

Bake at 350 degrees for 15-20 minutes or until center is just barely set.

While cake is baking , prepare crumb topping.

In large bowl of electric mixer combine , butter , flour , cinnamon , sugar and vanilla until all crumbly.

Immediately after cake is removed from oven , break crumb topping into marble size pieces with fingers , sprinkling over top.

Put back in oven and bake an additional 10-15 minutes.

Let cool fully then dust with powdered sugar , using a sieve.

Cut into squares and serve.
