I put these together for our FPU class and also the Ladies' Bible study. They are delicious.
Marshmallow Reeses Brownies
1 brownie mix (for a 9x13 pan)
1 bag Reese's Peanut Butter Eggs (or PB cups)
1 cup marshmallow cream
Spray a 9×13 pan with baking spray and set aside. Preheat the oven to 350 degrees. Prepare the brownie mix according to the package directions for fudge like brownies. Beat until just combined.
Spread half the brownie batter in the bottom of the prepared pan. Lay the peanut butter eggs on top of the batter. Drop spoonfuls of marshmallow cream around each egg. Top with the rest of the brownie batter. Spread the batter completely over all the marshmallow cream. You want all the marshmallow to be covered, so it doesn't burn as it bakes.
Bake for 25 - 30 minutes. Cool completely before cutting into the brownies. Store in a sealed container . Makes 24 brownies.
You can also use a bag of Reese's peanut butter cups the rest of the year.
