1 Box Yellow Cake Mix (plus ingredients on back of box)
2 Sticks cold salted butter
2 1/4 Cups flour
1 1/2 Tablespoons cinnamon
1 ¾ Cups brown sugar
1 1/2 Tablespoons vanilla
Powdered sugar (for dusting)
PREHEAT oven to 350.
Mix together the cake mix and place in a grease 9x13 pan. Cook for 15-20 minutes until just about done. (at 15 minutes mine was still shaky raw in the middle, so the full 20 it was).
When you have about 10 minutes left in baking the cake, it's a good idea to make the crumb topping.
When the cake is done, immediately crumble topping onto it and let cool.
Verdict: I admit I was hesitant about making this. I was like, "It's going to taste like a cake" but alas I really needed to use my eggs before they expired. It really is good and taste authentic. The last time I made from scratch coffee cake it was too dry, this was not!
