1/2 c. unsalted butter, softened
1/2 c. sugar
1/2 c. light brown sugar, packed
1/2 c. creamy peanut butter
1 egg
1 tsp. vanilla extract
1 tsp. baking soda
1/4 tsp. salt
1 c. all-purpose flour
1/2 c. quick-cooking oats
1/2 c. butterscotch chips
or 1/4 c. white chocolate chips and 1/4 c. butterscotch chips
Peanut Butter Icing
1/4 c. creamy peanut butter
1 c. powdered sugar
1 tsp. vanilla
pinch of salt
a few Tbl. of milk
Preheat oven to 350 degrees. Spray a 9x13x2-inch pan with cooking spray. Cream together butter, sugar, brown sugar and peanut butter until very light and fluffy. Mix in the egg and vanilla. Add the baking soda, salt, flour and oats and mix until combined. Press dough evenly into prepared pan. It will be very sticky and might not look like enough to fill the entire pan, but it will. Sprinkle butterscotch chips over the top. Bake for 20 minutes. Remove from oven and top with peanut butter icing. Allow to cool. Cut into squares and serve.
For the Peanut Butter Icing: Combine all ingredients and stir together until smooth and creamy. If mixture is too thick, add a little more milk. Spread over warm peanut butter bars.
