Ingredients for this cosmic brownie copycat recipe

Here are the ingredients you will need to make this small batch cosmic brownie recipe. Make sure to scroll down to the recipe card for the full detailed ingredient measurements. 

• Butter- You can use salted or unsalted butter for this recipe. 
• Oil- The vegetable oil will help give these brownies an extra chewy texture. 
• Granulated sugar & brown sugar- We are using a combination of sugars to really elevate both the flavors as well as the texture. 
• Egg- Make sure it is at room temperature. 
• Vanilla extract- This will help deepen the flavor of our brownies even more. 
• Salt- Always add a little salt to your baked goods to help balance out the sweetness of the dessert.
• Flour – All purpose flour works great for this recipe. 
• Cocoa powder- Make sure you are using high-quality unsweetened cocoa powder for this recipe. It will help the brownies taste even better. 
• Semi-sweet chocolate chips– The semi-sweet chocolate chips are used to make the chocolate ganache topping so making sure to use high quality is a must here too. Feel free to also use dark chocolate instead if you prefer. 
• Heavy cream – The heavy cream is also used to make the homemade version of the ganache that goes on top of our brownies. 
• Mini rainbow sprinkles – I used the rainbow chips which are made with chocolate in the center but if you can’t find those feel free to use mini m&m as well! The colorful sprinkles on top are a must for this special treat because they really bring it together just like the Little Debbie’s cosmic brownie bites that you can find at your local grocery stores.

Frequently asked questions – FAQ

How to store cosmic brownies for later?

You can store these brownies in an airtight container in the fridge for up to 4 days. Make sure to separate each layer with wax paper so they don’t stick to each other. Enjoy these right out of the fridge.

Can I make these brownies ahead of time for a special occasion?

You definitely can! These brownies store so well that you can make them ahead and keep them in an airtight container in the fridge for when you are ready to serve them. 

I highly recommend storing them in a flat container so that they look just as good as the day you made them. 

Can I freeze this small batch cosmic brownies?

Definitely! I highly recommend flash-freezing them on a flat surface to ensure that the rich ganache is set before transferring them to a freezer bag or an airtight container and freezing them for up to 3 months. Make sure to separate each layer with wax paper so they stay clean looking, and of course, thaw them on a flat surface in the fridge overnight before enjoying them whenever that chocolate craving hits!

Can I reduce the amount of sugar in the recipe without affecting the taste too much?

I would not recommend changing the measurements of this recipe since it has been tested a few times this way to really make it as best as possible. If you do change the ingredient measurements and love it, please let us know in the comments!

Yes! You can use canola oil, coconut oil, or even olive oil for a little extra depth of flavor in this recipe.
