Ingredients
- 12 tablespoons unsalted butter, melted
- 3/4 cup unsweetened cocoa powder
- 1 cup sugar
- 1/2 cup brown sugar, packed
- 2 teaspoons vanilla extract
- 2 large eggs
- 1 1/4 cups flour
- 1 teaspoon cornstarch
- 1/2 teaspoon salt
- 1 cup semisweet chocolate chips
- 1/2 cup milk chocolate chips
- 1/2 cup heavy cream
- 1/3 cup candy coated chips, rainbow
Instructions
- Step 1: Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius) and spray a 9×13-inch baking pan with baking spray.
- Step 2: In a bowl, whisk together the melted butter and cocoa powder until smooth and fully combined.
- Step 3: Add the sugar, brown sugar, eggs, and vanilla extract to the cocoa mixture, whisking until fully incorporated.
- Step 4: Sift the flour, cornstarch, and salt together, then gently whisk them into the wet ingredients until just combined — do not overmix.
- Step 5: Spread the batter evenly into the prepared baking pan and bake for 16-18 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs.
- Step 6: Allow the brownies to cool completely in the pan before frosting.
- Step 7: For the ganache, combine the semisweet and milk chocolate chips with the heavy cream in a large microwave-safe bowl.
- Step 8: Microwave the mixture for 1 minute, then let it sit for 2 minutes to melt fully. Stir until smooth and glossy.
- Step 9: Spread the ganache evenly over the cooled brownies and immediately sprinkle with the rainbow candy-coated chips before the ganache sets.
Tips & Variations
- Use a mix of different chocolate chips for a richer ganache flavor, such as bittersweet or white chocolate.
- For extra fudginess, slightly underbake the brownies by a minute or two.
- Substitute candy-coated chips with chopped nuts or sprinkles for different textures and flavors.
Storage
Store the brownies in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze for up to 3 months. Reheat chilled brownies briefly in the microwave to soften before serving.

FAQs
Can I use salted butter instead of unsalted butter?
Yes, but reduce the added salt in the recipe slightly to avoid an overly salty taste.
Do I need to refrigerate the brownies after adding ganache?
It’s not necessary if kept at room temperature and consumed within a few days, but refrigeration can extend freshness. Allow ganache to come to room temperature before eating for the best texture.
