Instructions

1. We like the Ghirardelli Double Chocolate Brownie Mix because of the rich dark chocolate taste and the extra chocolate chips in the batter but go ahead and use your favorite brand of brownie mix.  Make up the brownie batter according to the directions on the package and then add 1 cup of Reese's Peanut Butter Chips! 
2. Pour the Brownie batter into a 13" x 9" pan and bake according to the directions on the box. Allow the brownies to completely cool.
3. While the brownies are cooling, make a batch of our Best Peanut Butter Buttercream Frosting.  It is thick, peanut butter-y and so very yummy.  You can find the directions to make Best Peanut Butter Buttercream Frosting right here.
4. Add a thick layer of the Peanut Butter Frosting to the brownies after they are cool.
5. If you want to make the Brownie Bars a little fancier ... melt 1/2 cup of Semi-Sweet Chocolate Chips in a plastic bag in the microwave. Cut off a very tiny bit from the corner of the plastic bag and drizzle the melted chocolate over the top of the bars. Allow the drizzled chocolate to harden up before you store the brownies. These Brownie Bars are so yummy - chock full of both chocolate chips and peanut butter chips.
