Ingredients

Scale

Brownie Base

  • 10 tbsp unsalted butter, melted
  • 1 cup granulated sugar
  • 1/3 cup packed light brown sugar
  • 3/4 cup + 2 tbsp unsweetened cocoa powder, sifted
  • 2 large eggs + 1 egg yolk (for extra chewiness)
  • 1 tbsp corn syrup (for a fudgy texture)
  • 1/2 tsp vanilla extract
  • 2/3 cup all-purpose flour
  • 1 tbsp cornstarch
  • 1/4 tsp salt

Chocolate Ganache Frosting

  • 1/2 cup heavy cream
  • 1 1/2 cups semisweet chocolate chips

Topping

  • 1/4 cup rainbow candy-coated chocolate chips (or mini M&Ms)

Instructions

  • Preheat & Prep – Preheat oven to 350°F (175°C). Line an 8×8-inch metal baking pan with parchment paper.
  • Make the Batter – In a microwave-safe bowl, melt butter, then stir in granulated sugar, brown sugar, and cocoa powder until smooth. Let cool slightly.
  • Add Wet Ingredients – Mix in eggs, egg yolk, corn syrup, and vanilla extract until fully combined.
  • Incorporate Dry Ingredients – Gently fold in flour, cornstarch, and salt until just combined. Avoid overmixing.
  • Bake – Spread batter evenly into the pan and bake for 25 minutes, or until the edges are set and the center is slightly soft. Let cool completely.
  • Prepare Ganache – Heat heavy cream in the microwave for 1 minute until hot but not boiling. Pour over chocolate chips, let sit for 3 minutes, then stir until smooth.
  • Assemble & Chill – Spread ganache over cooled brownies and sprinkle with rainbow candy-coated chips. Refrigerate for 1-2 hours to set before slicing.

Notes

  • For extra chewy brownies, store them in the fridge and serve chilled.
  • Use a metal baking pan for best results—glass can cause uneven baking.
  • Swap rainbow chips for crushed peppermint, caramel drizzle, or peanut butter swirl for a fun twist.
