Mix all the ingredients for the cake in a mixer for 7 minutes (this is key to make the pudding set). Meanwhile, mix together brown sugar, sugar, and cinnamon in a bowl. Once the cake is done mixing for 7 minutes, pour half of the batter in the greased 9×13 metal pan. Sprinkle 1/2 of the brown sugar mix over the cake.
