Vee’s baking tips:

  • Make sure to have a prepared pan by greasing it with butter or cooking spray before adding the brownie mix. This will prevent the brownies from sticking to the pan.
  • For that homemade cosmic brownies taste, make sure to use a recipe that has a fudgy and chewy texture.
  • If you want to make this little Debbie brownie recipe in advance, store them in an airtight container for up to 3 days. This will keep them fresh and gooey.
  • When making the chocolate ganache, make sure to use high-quality chocolate for a smooth and rich flavor. I used allergy-friendly semisweet chocolate chips.
  • For an extra touch of fun, use different Disney cookie cutters to make different character shapes!
  • Make brownie pops and use a popsicle stick to create a fun and easy-to-eat version of these Mickey cosmic brownies. It might be easier to hold and a bit less messy.

How to make fudgy brownies

To make this fudge brownie recipe, you’ll need a gluten-free brownie mix. I personally love Krusteaz but feel free to use your favorite brand!

Follow the instructions on the box, but instead of using a traditional baking pan, get creative and use a Mickey Mouse cookie cutter to shape your brownies. This step will bring a fun and personalized touch to your brownies!

Note: You can just as easily make your brownies completely from scratch using any gluten-free brownie recipe you’d like. When I have the time, I love to use this recipe from Gluten Free On A String!

How to make chocolate ganache

To get that perfect chocolate topping, I used a homemade chocolate ganache!

If you’ve never had or heard of ganache, don’t worry – it’s really simple to make.

All you need is:

My secret ingredient is adding a tablespoon of instant espresso powder to the heavy cream while it is heating up. This gives the ganache a deeper, richer chocolate flavor.

Once it is heated through, pour it over the chocolate chips in a bowl and let it sit for two minutes. Then mix until smooth and creamy.

It’s that easy!

How to decorate Mickey’s copycat cosmic brownies

Once you have cooled brownies and they have been cut into Mickey shapes, it’s time to decorate them with the colorful crunch chips!

Pour a spoonful of ganache on top of each brownie and spread it evenly with a knife or spatula. Then, sprinkle the rainbow chips on top while the chocolate is still warm so they stick.

You can also get creative and use different colored sprinkles or mini M&Ms for an extra touch of magic.
