Peanut Butter Bars

I can never find this recipe when I "need" it so if I post it at least I will know where to find it.

Bars:

1 Cup soft butter
1 Cup sugar
1 Cup brown sugar
1 cup peanut butter
2 eggs
2 Cups flour
2 cups quick oats
1 tsp soda
1 tsp salt

Cream sugars and butter. Add eggs, peanut butter, flour, soda, salt and oats. Spread on a cookie sheet and bake at 350 for 15 to 20 minutes. (until light brown)

Frosting:

2/3 cup butter
1 tsp vanilla
1/3 cup cocoa
4 cups powdered sugar
3-5 Tbsp milk

whip butter until fluffy then add the rest of the ingredients. Start with a little milk and adjust for texture you want. (I like it thicker) Spread on bars when they are cool.
