Total Time40 Mins

Ingredients

• – 3/4 cup butter (unsalted, melted)
• – 1 cup granulated sugar
• – 2/3 cup brown sugar (packed)
• – 2 teaspoons vanilla
• – 2 eggs (room temp)
• – 1 1/4 cups flour
• – 3/4 cup unsweetened cocoa powder
• – 1/2 teaspoon baking powder
• – 1 Tablespoon cornstarch
• – pinch of salt
• – 3 Tablespoons milk
• – 3/4 cup heavy whipping cream
• – 1 cup semi sweet chocolate chips
• – 2 small bags of Rainbow Chips

Instructions

1. 1
   Oven and Pan Prep: Adjust your baking oven to 350 degrees and line a 9x13" baking pan with non-stick parchment paper. Lightly coat the inner surface with cooking spray and place it aside.
2. 2
   Beat Creamed Mixture: Combine your melted unsalted butter, granulated white sugar, packed brown sugar, and vanilla extract inside a large mixing bowl using a hand or stationary stand mixer.
3. 3
   Mix in Eggs: Incorporate the room temperature eggs one by one, beating continuously until the mixture is thoroughly combined.
4. 4
   Whisk Dry Ingredients: In a separate container, stir together your all-purpose flour, unsweetened cocoa powder, baking powder, cornstarch, and fine salt using a whisk.
5. 5
   Build the Thick Batter: Slowly introduce the dry ingredient blend into your prepared wet batter, running the mixer at a slow setting. Alternate between adding the flour mixture and the milk until everything is unified. The resulting batter will turn out quite dense and thick.
6. 6
   Spread in Pan: Transfer the dense batter into your lined baking dish and use a flat spatula to smooth it into an even layer across the pan.
7. 7
   Bake Carefully: Bake the mixture at 350°F for roughly 18 to 25 minutes, monitoring closely to prevent the base from drying out or overcooking.
8. 8
   Cool Completely: Take the dish out of the oven and leave the brownie slab inside the pan to cool down fully.
9. 9
   Simmer Cream & Melt: Warm your heavy whipping cream inside a small saucepan until it reaches a gentle simmer. Remove the hot cream from your stovetop burner, drop in the semi-sweet chocolate chips, and let them rest undisturbed for a few minutes before whisking into a smooth, liquid glaze.
10. 10
    Apply Ganache Layer: Empty the warm chocolate ganache over your cooled brownie base and distribute it uniformly with a clean spatula.
11. 11
    Decorate with Candy: Scatter the contents of your two bags of Rainbow Chips across the top surface while the glossy chocolate glaze remains warm and sticky.
12. 12
    Set and Enjoy: Leave the entire pan to set up completely, then slice into squares and serve!

Frequently Asked Questions

What is the secret to getting that dense, fudgy Cosmic Brownie texture? The secret lies in the inclusion of cornstarch and a minimal amount of baking powder. This prevents the brownies from rising too much or developing a cake-like texture, ensuring they stay perfectly dense, fudgy, and chewy just like the original snack cakes.

Where can I find Rainbow Chips for this copycat recipe? Rainbow Chips are specific candy-coated chocolate pieces (not regular sprinkles). They can usually be found in the baking aisle of major supermarkets, craft stores with a baking section, or purchased easily online. Brands like Betty Crocker often sell them as "Rainbow Chip" crunch sprinkles.

How should I store these brownies and how long do they stay fresh? Store your sliced brownies in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to 5 days. Keeping them in the fridge makes them extra fudgy and delicious! Just let them sit at room temperature for 10 minutes before eating if you prefer a softer bite.
