Recipe type: Dessert
Cuisine: American
Serves: one 9x13 pan
  • 7 ounce jar of marshmallow fluff
  • 8 drops + green food coloring, or until desired shade of green is reached
  • 1 box of brownie mix – make according to directions on the box
  • 12 Mint Oreo Cookies + 18 Mint Oreo Cookies (an entire package), crumbled by hand
  • ¾ cup white chocolate chips, melted
  • 1 batch vanilla frosting (below)
  • ½ cup butter or margarine, softened
  • 3 to 4 cups powdered sugar
  • 1 teaspoon vanilla extract
  • a splash of milk, if necessary for consistency
  1. Preheat oven to 350°F. Line a 9×13-inch pan with foil and spray it with cooking spray. In medium bowl, stir together marshmallow fluff and 4 drops of food coloring, or until light green color is achieved.
  2. In a large bowl, prepare the brownie mix as directed on box, using water, oil, eggs, and then fold in 12 hand-crumbled Oreos.
  3. Spread brownie batter in prepared pan. Drop about ½ cup of green marshmallow mixture onto brownie batter and reserve the remainder. Gently pull a table knife through the batter in S-shaped curves for a swirled design. Bake 23 to 25 minutes or until brownies are set, do not overbake. Cool completely or put the pan into the freezer for 10 minutes if you are in a hurry.
  4. While brownies are cooling, make vanilla frosting by combining the following and beating until fluffy and set frosting aside once done.
  5. In another small microwave-safe bowl, melt the white chocolate chips (microwave on high for 30 seconds; stir and microwave 30 seconds longer; stir until smooth, be careful not to scorch as white chocolate scorches easily.
  6. Add the melted white chocolate chips and the vanilla frosting to the reserved green marshmallow mixture. Stir in 4 drops or more of food coloring, or until light green color is achieved, and spread over cooled brownies.
  7. Sprinkle with 18 hand-crumbled Oreos, slightly pressing them into the green mixture. Allow top layer to set fully before slicing and serving.
  8. You can store these in the refrigerator in an airtight container if you prefer them chilled or freeze for up to 3 months.
