1 cup butter

1 cup granulated sugar

1 cup brown sugar

2 eggs

2/3 cup peanut butter

1 teaspoon vanilla

2 cups flour

2 cups oatmeal

Topping:

12 ounces chocolate chips

½ cup powdered sugar

¼ cup peanut butter

2 to 4 tablespoons milk

Preheat oven to 350 degrees. 

Cream together butter and sugars. 

Add eggs and peanut butter. 

Stir until smooth. 

Add remaining ingredients (excluding topping ingredients) and mix until evenly blended.  Grease a 9-by-13-inch baking dish. 

Press mixture evenly into the pan. 

Bake for 20 minutes. 

Remove from oven, cover immediately with chocolate chips and allow chips to melt, and then spread evenly. 

Blend together powdered sugar, peanut butter and milk until smooth. 

Spread topping mixture evenly over the melted chocolate chips, making a swirl pattern.  Cool, cut and serve.

This is the ideal take-along dessert for picnics, family reunions and church suppers.
