Whether you’re a brownie aficionado or just looking to recreate a favorite treat, this comprehensive recipe guide will walk you through creating your own Cosmic Brownies from scratch.
Ingredients
Brownie Base
- ¾ cup all-purpose flour (90 grams) – For a gluten-free version, use a 1:1 gluten-free flour blend.
- ⅔ cup unsweetened cocoa powder (56 grams)
- 12 tablespoons unsalted butter (170 grams, melted; equivalent to 1½ sticks) – If using salted butter, omit the kosher salt.
- 1 cup granulated sugar (200 grams) – Brown sugar can also be used for a deeper flavor.
- ½ cup brown sugar (107 grams)
- 2 large eggs (approximately 50 grams each, at room temperature)
- 1 teaspoon pure vanilla extract (4 grams)
- ¾ teaspoon kosher salt
Topping
- 1 cup chocolate chips (170 grams) – Milk, semisweet, or dark chocolate chips all work well.
- ½ cup heavy cream (114 grams)
- ¼ cup rainbow candy-coated chocolate chips (43 grams) – Mini M&M’s or rainbow sprinkles can be used as a colorful alternative.
Instructions
Step 1: Prepare Your Baking Pan
- Preheat your oven to 325°F (163°C).
- Spray a 9×9-inch baking pan with nonstick spray and line it with parchment paper, leaving some overhang for easy removal later.
Step 2: Make the Brownie Batter
- In a medium bowl, whisk together the all-purpose flour and cocoa powder until well combined.
- In a separate larger bowl, whisk the melted butter with the granulated and brown sugars until the mixture is smooth.
- Add the eggs, vanilla extract, and kosher salt to the sugar mixture. Whisk until everything is well incorporated.
- Gradually fold the dry ingredients into the wet ingredients, stirring gently until just combined. Avoid overmixing, as this can lead to tough brownies.
Step 3: Bake the Brownies
- Pour the brownie batter into the prepared baking pan and spread it evenly with a spatula.
- Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
- Allow the brownies to cool in the pan.
Step 4: Prepare the Frosting
- While the brownies are cooling, heat ½ cup of heavy cream in a small pot over medium heat.
- Once the cream is hot, remove it from the heat and add the chocolate chips. Stir until the chocolate is completely melted and the mixture is smooth.
Step 5: Assemble the Cosmic Brownies
- Pour the chocolate frosting over the cooled brownies, spreading it evenly with a spatula.
- Immediately sprinkle the rainbow candy-coated chocolate chips or your preferred topping over the frosting.
Step 6: Set and Serve
- Place the brownies in the refrigerator or freezer to allow the frosting to set.
- Once set, lift the brownies from the pan using the parchment paper overhang and slice into squares. For clean cuts, dip a sharp knife in hot water and wipe it dry between slices.
Tips for Success
- Pan Lining: Don’t skip lining your pan with parchment paper. It ensures easy removal and clean edges.
- Butter Alternatives: You can substitute butter with a neutral oil like vegetable or canola, but keep in mind that the texture may be slightly different.
- Storage: Store any leftover brownies in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
