Peanut Butter-Chocolate Cake

Cake:
2 cups flour
1 cup brown sugar
2 tsp baking powder
1/2 tsp baking soda
1/4 tsp salt
1 cup milk
1/2 cup peanut butter
2 eggs
1/4 cup marg.
Beat with an electric mixer on low speed until combined. Beat on Med/High speed for 3 minutes.
Then if desired add 1/2 cup mini chocolate chips.

Topping:
In a separate bowl combine:
1/2 cup flour
1/2 cup brown sugar
Using a pastry blender cut in 1/4 cup peanut butter and 3 tbsp marg until the mixture resembles course crumbs.
If desired mix in 1/4 cup mini choc chips.

Pour batter in greased 13x9x2. Sprinkle evenly with topping. Bake at 375 for 30 minutes or until toothpick comes out clean.

I also tend to drizzle homemade chocolate icing or melted milk chocolate over the top after baking.
