Ingredients

Scale
  • 1 cup (226 grams) unsalted butter, melted
  • 2 cups (400 grams) granulated sugar
  • 4 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 1 cup (125 grams) all-purpose flour, sifted
  • 3/4 cup (75 grams) unsweetened cocoa powder
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking powder
  • 1 cup (170 grams) bittersweet or semi-sweet chocolate chips
  • 1/2 cup (120 ml) heavy cream
  • 2 tablespoons (28 grams) unsalted butter, softened
  • 1/3 cup (about 50 grams) cosmic or rainbow sprinkles

Instructions

  1. Preheat oven to 350ยฐF (175ยฐC). Grease a 9×13-inch baking pan or line it with parchment paper, leaving some overhang for easy removal.
  2. In a large bowl, whisk together melted butter and granulated sugar until smooth and glossy, about 2 minutes.
  3. Add eggs one at a time, whisking well after each addition. Stir in vanilla extract.
  4. In a separate bowl, sift together flour, cocoa powder, salt, and baking powder.
  5. Gradually fold dry ingredients into wet mixture using a wooden spoon or spatula until just combined; do not overmix.
  6. Pour batter evenly into prepared pan and smooth the top with a spatula.
  7. Bake for 25-30 minutes, checking at 25 minutes. Brownies should be set around edges but slightly soft in center; a toothpick inserted should have a few moist crumbs.
  8. While baking, prepare ganache by combining chocolate chips and heavy cream in a microwave-safe bowl. Heat in 30-second intervals, stirring between, until smooth and glossy.
  9. Stir in softened butter until fully melted and incorporated.
  10. Let brownies cool in pan for 15 minutes after baking.
  11. Pour ganache evenly over brownies and immediately sprinkle cosmic sprinkles on top before ganache sets.
  12. Chill brownies in refrigerator for at least 30 minutes to firm up ganache.
  13. Use parchment overhang to lift brownies out of pan and cut into squares. Wipe knife between slices for clean cuts.

Notes

Do not overmix the batter to avoid cakey brownies. Use room temperature eggs for better batter consistency. Watch baking time closely to keep brownies fudgy. Use quality chocolate for ganache for best flavor and texture. Heat ganache in short bursts and stir often to avoid burning. Add butter last to ganache for shine and smoothness. Chill brownies after ganache application for best texture and easier slicing. If ganache is too thick, warm gently again but do not overheat. Variations include adding nuts, espresso powder, or using gluten-free flour and dairy-free substitutes.
