2 cups white sugar
Add 1 cup of sour cream, 2 eggs, and 1/2 tsp of vanilla.. Mix well. Slowly mix in the flour, baking powder, salt mixture until thoroughly combined
Grease a 9x13 baking dish and spread half the batter in the pan with a spatula, top with half the brown sugar topping mixture. Repeat with the other half of batter and topping mixture. Note: the dough/batter is very sticky. Use patience and spread it slowly with a spatula. If you do it too fast the batter will stick to the spatula and be difficult to spread.
Bake at 350 F for 30-35 or until an inserted toothpick comes out clean. Brew up that coffee, send the kids away, grab the paper, and relax. Enjoy!!!
