Ingredients

Scale
  • 1 box brownie mix (about 18 oz)
  • 2 large eggs (or as required by brownie mix)
  • 1/2 cup vegetable oil (or as required by brownie mix)
  • 1/4 cup water (or as required by brownie mix)
  • Pinch of salt (optional)
  • 1 sleeve Thin Mint cookies (about 16 cookies, or 5.3 oz)
  • 4 oz cream cheese, softened
  • 1/2 teaspoon peppermint extract (optional)
  • 10 oz semi-sweet or dark chocolate chips
  • 1 tablespoon coconut oil or vegetable shortening
  • Green sprinkles or sanding sugar (optional, for decorating)
  • Crushed Thin Mint cookies (optional, for decorating)
  • 2 oz white chocolate (optional, for drizzle)

Instructions

  1. Preheat oven to 350°F (175°C). Grease or line a 9×13-inch baking pan.
  2. Prepare brownie mix according to package instructions (usually with eggs, oil, and water). Stir until just combined.
  3. Pour batter into pan and bake for 22-25 minutes, until a toothpick comes out fudgy but not wet. Cool completely (at least 1 hour).
  4. Place Thin Mint cookies in a zip-top bag and crush with a rolling pin or pulse in a food processor until fine crumbs form.
  5. In a large bowl, crumble cooled brownies. Add crushed Thin Mints, softened cream cheese, and peppermint extract (if using). Mix until fully combined and mixture holds its shape.
  6. Scoop 1-inch balls of mixture and roll between palms to smooth. Place on parchment-lined baking sheet. Freeze for 20 minutes.
  7. Melt chocolate chips and coconut oil in a microwave-safe bowl in 30-second bursts, stirring until smooth, or use a double boiler.
  8. Dip each chilled truffle into melted chocolate, turning to coat. Let excess drip off, then place back on parchment-lined sheet.
  9. Decorate immediately with sprinkles, crushed cookies, or white chocolate drizzle if desired.
  10. Refrigerate truffles for at least 30 minutes until chocolate is set. Serve chilled or at room temperature.

Notes

Let brownies cool completely before mixing for best texture. Don’t overbake brownies—slightly fudgy is best. Chill truffle mixture if too sticky. Use gloves or lightly oil hands for rolling. Melt chocolate slowly to avoid seizing. Work in batches to keep truffles firm. Decorate while chocolate is wet. Easily adapted to gluten-free or dairy-free diets.
