Cream:

2/3 c. butter
1 c. brown sugar

Add:

1/2 c. corn syrup
3 tsp. vanilla
4 c. rolled oats

Optional ingredients:

Toasted almonds
Toasted coconut
Raisins

Bake at 350 degrees for 15-20 minutes in a WELL buttered 13 x 9 inch pan. Cut before too cool. Best if not too done as even golden brown gets too hard if fairly soft after baking. Cool COMPLETELY before removing from pan.

FROSTING:

1 (6 oz.) semi-sweet chocolate chips
2/3 c. peanut butter

Melt together. Spread on partly cooled bars.
