Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, melted
  • 2 cups granulated sugar
  • 4 large eggs
  • 1 teaspoon vanilla extract
  • 3/4 cup unsweetened cocoa powder
  • 1 cup all-purpose flour
  • 1/2 teaspoon salt
  • 1/2 cup semi-sweet chocolate chips, melted
  • 1/2 cup colorful candy-coated chocolate chips (sprinkles) for topping
  • 1/2 cup heavy cream (for ganache)
  • 1 cup semi-sweet chocolate chips (for ganache)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and line a 9×13 inch baking pan with parchment paper, leaving an overhang for easy removal.
  2. In a large bowl, whisk the melted butter and sugar together until combined.
  3. Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  4. In a separate bowl, whisk together the cocoa powder, flour, and salt.
  5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
  6. Stir in the 1/2 cup of melted semi-sweet chocolate chips.
  7. Spread the batter evenly into the prepared pan.
  8. Bake for 25 to 30 minutes. A toothpick inserted near the center should come out with moist crumbs attached, not wet batter.
  9. Let the brownies cool completely in the pan on a wire rack.
  10. Prepare the ganache: Heat the heavy cream in a small saucepan until it just simmers. Remove from heat.
  11. Place the 1 cup of chocolate chips for the ganache in a heatproof bowl. Pour the hot cream over the chips. Let stand for 5 minutes, then whisk until smooth and glossy.
  12. Pour the ganache over the cooled brownies and spread evenly.
  13. Immediately sprinkle the colorful candy-coated chocolate chips over the wet ganache.
  14. Allow the ganache to set before cutting into squares.

Notes

  • For an extra fudgy texture, slightly underbake the brownies by about 2 minutes.
  • Use high-quality cocoa powder for the best chocolate flavor.
  • If you do not have candy-coated chocolate chips, you can use standard rainbow sprinkles, but the texture will differ slightly.
