adapted from Connor's Cooking
1 3/4 cups flour
3/4 tsp baking soda
1/4 tsp salt
3/4 cup unsalted butter, softened
1 cup creamy or chunky peanut butter
1/2 cup sugar
1/2 cup packed light brown sugar
1 egg
1 tsp vanilla
12 oz. chopped semi sweet chocolate
Preheat oven to 375° F. Grease a 9 X 12 baking dish.*
Mix together the flour, soda and salt.
Cream the butter, sugars, and peanut butter until light and fluffy. Beat in the egg and vanilla until combined. Turn the mixer to low and slowly add the dry ingredients. Fold in the chocolate by hand.
Press the dough into the prepared baking dish and bake 20-22 minutes or until golden brown. Cool on wire rack in the pan. When cooled completely, cut into bars and serve!
*Connor suggests that you can also line the dish with foil so that the bars can be easily lifted from the pan.
