■ PEANUT BUTTER: Use a peanut butter brand you like for the best tasting results. I prefer Skippy. NOTE: A crunchy peanut butter or smooth peanut butter may be used in the recipe.

■ CHOCOLATE: Semi sweet chocolate chips and peanut butter are the perfect combination. I melt mine on the stovetop with a little milk then spread it across the bars once it’s warm and smooth.

■ BUTTER: A classic baking staple. Use a good quality butter for the best flavor.

■ SUGAR: A little bit of sweetness adds great flavor to this rich dessert.

■ FLOUR: The dough will be mix up thick once flour is added resulting in a sturdy cookie base. Simply use a spatula or your hands to spread it into a casserole dish.

Can I freeze the cookie bars? Yes. Simply bake, top with melted chocolate and allow to cool in the pan. Next, cut into squares and place in an air-tight bag. Store for up to 3 months.
