1 Box Yellow Cake Mix
Mix as directed and place in 350 oven in greased 13x 9 pan . Cook cake until just firm enough for crumbs to sit on top without falling through batter.
2 cups flour
2 sticks butter
3/4 cup brown sugar
1/2 cup sugar
6 tbls of cinnamon
Mix the flour butter sugars and cinnamon together until crumbly. I use a fork to blend or you can use a pastry cutter.
Once the mixture is the texture of large crumbs place onto the cake while still firm not fully cooked. Continue cooking cake until the crumbs are lightly browned and cake tests done.
