Description

Homemade cosmic brownies deliver nostalgic chocolate goodness with rich fudgy layers and colorful sprinkle toppings. Rich chocolate bases combine with sweet ganache and playful rainbow chips for classic lunchbox dessert memories.


Ingredients

Scale
  • 4 oz (113 g) semisweet chocolate, chopped
  • 4 oz (113 g) milk chocolate, chopped
  • ½ cup (120 ml) heavy cream
  • 1 tbsp (15 ml) butter, cut into 4 pieces
  • ½ cup (75 g) rainbow chip sprinkles

Instructions

  1. Prep Station: Warm the oven to 350°F (177°C) and line a 9-inch × 9-inch pan with parchment paper, creating easy-lift edges and lightly coating with cooking spray.
  2. Butter Blend: Melt butter in a microwave-safe bowl, then vigorously whisk sugar until the mixture transforms into a smooth, integrated base.
  3. Mixing Mastery: Transfer to a stand mixer, whipping the butter-sugar combination until it becomes light and airy. Introduce eggs and vanilla, continuing to beat until the batter achieves a pale, thick consistency.
  4. Dry Ingredient Fusion: Carefully fold in flour, cocoa powder, and salt, mixing on low speed to prevent overmixing. Gently incorporate milk to create a uniform, silky texture.
  5. Baking Performance: Pour the batter into the prepared pan, ensuring an even distribution. Bake for 20-25 minutes, verifying doneness with a toothpick that should emerge with minimal crumbs.
  6. Ganache Creation: Heat heavy cream in short microwave bursts, then merge with chopped chocolate. Allow to rest briefly before stirring into a glossy, smooth ganache. Blend in butter for extra richness.
  7. Finishing Touches: Once brownies cool completely, lavish the surface with the chocolate ganache, using a spatula to create a flawless layer. Sprinkle decorative toppings for visual and textural intrigue.
  8. Serving Technique: Refrigerate for 1-2 hours until the topping sets firmly. Lift from the pan using parchment edges, slice into precise squares, and indulge in these decadent delights.

Notes

  • Prevent Overbaking: Check brownies at 20 minutes to ensure a fudgy, moist texture; slightly underbaked is better than dry.
  • Smooth Ganache Technique: Let hot cream sit with chocolate for exactly one minute before stirring to create a perfectly glossy, lump-free chocolate topping.
  • Room Temperature Ingredients: Bring eggs to room temperature before mixing to help achieve a more uniform, lighter batter consistency.
  • Cutting Clean Squares: Use a sharp, warm knife wiped between cuts for precise, clean-edged brownie portions.
