Common Questions About Cosmic Brownies

What makes these brownies different from other brownie recipes?

This is a copycat recipe. However, these Cosmic Brownies stand out because of their fudgy texture and the addition of colorful rainbow sprinkles on top.

The combination of cocoa powder and chocolate ganache gives them a rich chocolate flavor, while the sprinkles add a fun and festive touch.

Can I use a different type of chocolate for the frosting?

Yes, you can use semi-sweet or dark chocolate chips for the ganache. If you prefer a sweeter frosting, milk chocolate chips work well too. Just make sure to adjust the amount of heavy cream to get the right consistency for the chocolate ganache.

How do I store these brownies?

You can store Cosmic Brownies in an airtight container at room temperature for up to 3 days, in the refrigerator for up to a week, or freeze them for up to 3 months. They’re perfect for making ahead and enjoying later!

Storage

The only thing I’ll say is that these don’t typically make it to storage. They’re just too good!

Refrigerator

Store your brownies in an airtight container in the fridge for up to a week. This keeps them fresh and maintains their fudgy texture.

Freezer

Freeze the brownies for up to 3 months. Wrap each brownie individually in plastic wrap and place them in a freezer-safe container. Thaw at room temperature before serving.

Tips

For some reason, these are locked into my memory alongside Zebra Cakes. I can’t think of one without the other, haha!

• Use room temperature ingredients: This helps everything mix together smoothly.
• Line your pan: Use parchment paper to line your baking pan for easy removal.
• Don’t overbake: Keep an eye on the brownies and remove them as soon as the center is set.
• Chill the brownies: Allow them to chill in the fridge to set the ganache perfectly.
• Cut with a sharp knife: For clean edges, use a sharp knife and wipe it between cuts.

How to Make Cosmic Brownies

Don’t worry, I’ve got some really simple steps for this homemade cosmic brownie recipe. Get ready for awesomeness!

1. Preheat the oven to 350 degrees.  
2. Line a square 8×8 or 9×9 baking pan with parchment or foil and then spray it with non-stick spray.  Set aside. 
3. Combine the melted cocoa powder, granulated sugar, melted butter, and brown sugar in a medium bowl.  The mixture will be thick. 
4. Add in the eggs, egg yolk, corn syrup, and vanilla.  Mix until thoroughly combined. 
5. Mix in the flour, cornstarch, and salt. Stir just until combined.  The batter will be thick – that’s what you want. 
6. Transfer the batter to the prepared pan and spread it to the edges in an even layer. 
7. Bake for 25-30 minutes or until the center is set.  
8. Allow to cool before decorating. 

Frosting

1. Combine the chocolate chips and heavy whipping cream in a microwavable bowl.  Heat for one minute.  
2. Remove from the microwave and stir until all the chips have melted and the ganache is smooth.  Only if needed, heat for an additional 15-30 seconds or until all the chips have melted.  Do not overheat. 
3. Pour the ganache frosting over the cooled brownies and spread it to the edges.  
4. Decorate with a light layer of sprinkles, rainbow morsels, or extra chocolate chips.  
5. Allow the brownies to cool in the fridge for about 2 hours or at room temp for about 4 hours before serving.
