Peanut Butter Bars

1/2 cup butter
1/2 cup sugar
1/2 cup brown sugar
1 egg
1 t. vanilla
1/3 cup peanut butter
cream together, then add:
1/2 t. baking soda
1 c. flour
1 c. oats
mix until blended and spread into a greased 9 x 13 baking dish. this part gets tricky because it doesn't look like there's enough batter to fill the entire dish. use a non stick spreader and spread it all out even if it's thin. they puff once they bake and turn into the perfect thickness! bake in a preheated 350 degree oven for 15-16 minutes or until edges are slightly golden brown. do not overbake!

over cooled bars, spread
1/4 cup peanut butter

then frost with chocolate frosting:
1/4 cup softened butter
1 - 3 T cocoa
1 1/2 c. powdered sugar
milk
