Perfectly chewy with a deep chocolate flavor enhanced by both cocoa powder and semisweet chocolate, these brownies are baked to perfection and chilled for the ideal texture. A fun and indulgent treat for any occasion, they combine classic brownie comfort with a festive twist.


Ingredients

Brownies

  • 10 tbsp unsalted butter
  • 4 oz semisweet chocolate, chopped
  • 3/4 cup (150g) light brown sugar, packed
  • 1/2 cup (100g) granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 3/4 cup (95g) all purpose flour
  • 1/4 cup (20g) unsweetened cocoa powder
  • 1/4 tsp salt

Ganache and Topping

  • 3/4 cup (120g) semisweet chocolate chips
  • 1/4 cup (60ml) heavy whipping cream
  • Rainbow coated chocolate sprinkles


Instructions

  1. Prepare Baking Dish: Preheat the oven to 350°F (177°C) and grease and line an 8×8 inch square baking dish with parchment paper, allowing the paper to hang over the edges for easy brownie removal.
  2. Melt Butter and Chocolate: In a heat-safe bowl, melt the butter and chopped semisweet chocolate together in the microwave using 30-second intervals, stirring between intervals until smooth, about 90 seconds total.
  3. Mix Sugars and Eggs: In a large bowl, vigorously whisk together the light brown sugar, granulated sugar, and eggs for 1-2 minutes until the mixture is pale and creamy. Stir in the vanilla extract.
  4. Combine Chocolate Mixture: Gradually pour the melted chocolate mixture into the egg mixture while whisking continuously until fully combined.
  5. Add Dry Ingredients: Switch to a rubber spatula and fold in the all-purpose flour, unsweetened cocoa powder, and salt gently, taking care not to overmix to keep the brownies tender.
  6. Bake the Brownies: Pour the batter into the prepared baking pan and spread evenly. Bake for 20-25 minutes until a toothpick inserted near the center comes out with moist crumbs.
  7. Cool and Chill: Let the brownies cool in the pan for 30 minutes, then transfer to the refrigerator to chill for 1-2 hours until fully set.
  8. Make the Ganache: Place the semisweet chocolate chips in a small bowl and heat the heavy cream in a microwave-safe dish for about 1 minute or until bubbling hot. Pour the hot cream over the chocolate chips and let sit for 30 seconds. Whisk until smooth and glossy.
  9. Apply Ganache and Sprinkles: Pour the ganache evenly over the chilled brownies and spread with a spatula. Sprinkle rainbow-coated chocolate sprinkles over the ganache while still wet.
  10. Final Chill and Serve: Return the brownies to the refrigerator for 30 minutes to 1 hour, or until the ganache is completely set. Use the parchment paper overhang to lift the brownies out of the pan, slice into 16 squares, and enjoy your cosmic treat!

Notes

  • Allow the brownies to chill thoroughly before adding ganache to prevent melting or running.
  • You can substitute the heavy cream with full-fat coconut milk for a dairy alternative.
  • For thicker ganache, use a bit more chocolate chips or reduce cream slightly.
  • Ensure not to overmix the batter to maintain fudgy texture.
  • Store leftover brownies in an airtight container in the refrigerator for up to 5 days.
