Jeff's Peanut Butter Brownies

This one came from my mom who I think got it from my Grandma. I love it and my friend Denise has also fell in love with it.

2 sticks butter
2 c. brown sugar
2 eggs
2 c. flour
2 c. quick oatmeal

Mix all ingredients in the order given and then pat into a cookie sheet with sides. Bake for 22 minutes at 350.
Remove from oven, spread with peanut butter and top with chocolate icing. While still warm cut into squares and let cool.

I have found that this is easiest if you have a food processor to mix it up in. Add 1 ingredient at a time and then mix
