Okay time to revive this thread...it's january and not much else to do so why not bake and cook?
I took these to school this week and they were very well received...I didn't take a picture of them before they were gobbled up!
Thanks Rebar cookbook for this one!!!

Killer Peanut Butter Squares with Milk Chocolate and Oats
Rebar: Modern Food Cookbook

The recipe suggests you can drizzle the finished squares with melted chocolate after icing them.

Yields 8"x8" pan

1/2 cup unsalted butter, softened
1/2 cup brown sugar
1/2 cup white sugar
1/3 cup smooth peanut butter
1 egg
1/2 tsp vanilla
3/4 cup rolled oats
1 cup unbleached flour
1/2 tsp baking soda
1/4 tsp salt
4 oz (120 g) milk chocolate, chopped into large chunks

Icing
1/2 cup smooth peanut butter
2 tbsp soft butter
1/2 tsp vanilla
1 cup icing sugar
1/4 cup heavy cream

1. Preheat the oven to 350F. Grease an 8" x 8" pan and set aside. Cream together the butter, sugars and peanut butter until light and fluffy. Add the egg and vanilla and mix well.

2. Combine the oats, flour, baking soda and salt in a separate bowl. Add this to the butter/peanut butter mix and stir well. Fold in the chocolate chunks. Spread into the prepared pan and bake 25 minutes. Set aside to cool.

3. Prepare the icing by creaming together the peanut butter, butter and vanilla. Blend in icing sugar. Stir in cream until you get a nice spreading consistency, using more if necessary.

4. Divide into squares and serve.
