Prepare a baking dish that will hold 16 halved peanut butter cups. I use an 11" x 8" dish. Grease the bottom of the dish, or line with parchment paper.
Unwrap eight peanut butter cups from their wrapper and cut them in half.
In a small bowl beat the two eggs.
In a large bowl add the brownie mix, water, oil, and the beaten eggs and mix with a spoon just blended.
Stir in the chocolate chips
Pour half of the brownie batter into the baking pan, then top with the 16-halved peanut butter cups. Pour the rest of the brownie batter over the top of the peanut butter cups and spread to cover.
Bake the brownies for 25 - 30 minutes. When done let cool for about 30 minutes then cut into squares.
Cover the leftover brownies with plastic wrap.
Notes
To change these Reese's peanut butter brownies up try using
Mini peanut butter cups, just space them apart on top of the first layer of batter and top with the second layer of batter.
Use eight whole peanut butter cups.
