Original recipe yields 1 1/2 dozen



  1. Preheat oven to 325 degrees F (165 degrees C).
  2. Combine brownie mix, oil, egg and water in a large bowl. Stir 50 strokes with a spoon.
  3. Place batter in a cupcake pan (cupcake wrappers recommended). Once cups are 3/4 of the way full, place an unwrapped miniature peanut butter cup in the middle, then bake for 30-35 minutes keeping an eye on them while they're baking. Let them cool and then they're ready to eat!!

It seems there were a number of reviewers who experienced some problems with this which hopefully my suggestions will remedy. Prepare these as your brownie package directs, since they all differ slightly. Bake these in foil liners to eliminate the sticking issue. And only fill the cups half full, no more. You should get 24 brownies with a nice balance of brownie to peanut butter cup. Do not overbake! Just bake these till a toothpick comes out ALMOST clean (mine took just 18 minutes). These are fudgey, gooey, delightfully cute, just the right size and, for some reason I don't understand since this is, after all, a boxed mix, irresistably delicious. I agree with JENNIEMC1975's review.

As the other reviewers did, I followed the directions on the box and used 1/2 cup vegetable oil, 1/4 cup water and two eggs for a fudgy brownie. I used three packages of the mini Reese's in this recipe. Instead of baking them in muffin cups, I baked mine in my Perfect Brownie Pan. 350* for 33 minutes was spot on for me. My family LOVED these brownies--they must because half of the pan is already missing.



I, too, followed the directions on the brownie box. I added a third egg to make them more cake-like. For the first batch, I used a regular sized muffin tin, but I thought the peanut butter cup got lost in the brownie and it just wasn't that great. The next batch I made mini muffins and these were fantastic!! I made sure I watched them carefully so the tops didn't get too hard. They came out so freakin' good! Will definitely make these again!
