Let's get baking — for one!
Quick Recipe Overview
SERVINGS: 1 mini cosmic brownie
PREP TIME: 5 minutes
COOK TIME: 1 minute
TOTAL TIME: 6 minutes
Things You'll Need
2 Tbsp. unsalted butter
2 Tbsp. cocoa powder
1 or 2 Tbsp. chocolate chips
4 Tbsp. all-purpose flour
2 Tbsp. sugar
1/4 tsp. baking powder
2 Tbsp. milk
1/4 cup chocolate frosting
1 Tbsp. mini M&M's
Tip
If you'd like a more traditional cosmic brownie look, use rainbow candy-coated chips instead of mini M&M's. You can also use regular rainbow sprinkles if that's what you have on hand.
1. Combine the butter and cocoa powder
Add the butter to a small microwave-safe dish, like a glass or ceramic ramekin. Microwave for 20 to 30 seconds or until the butter is completely melted.
Add the cocoa powder and chocolate chips and then mix until combined.
Tip
For an extra-fudgy brownie, add extra chocolate chips.
2. Add the remaining ingredients
To the butter mixture, add the flour, sugar, baking powder, and milk. Stir until the flour is fully incorporated.
3. Microwave the brownie
Heat the brownie in the microwave for 1 minute on high. If the brownie is not fully set, heat for another 30 seconds. Let the brownie sit until it's mostly cooled.
Warning
Use caution when removing the dish from the microwave; it will be very hot.
4. Top with the icing and candies
Spread chocolate frosting on the brownie and then top with mini M&M's.
Tip
To make this treat even tastier, top off the brownie with a scoop of vanilla ice cream or a dollop of whipped cream.
