- All Purpose Flour

- Granulated Sugar
- Brown Sugar – Both the sugars adds a really sweet flavor to the brownies.
- Egg – The egg acts as the binder keeping the batter together.
- Unsalted Butter- If you use salted just omit salt in the recipe.
- Oil – Canola or vegetable oil works for this recipe.
- Semi-Sweet Chocolate Chips

- Rainbow Sprinkles – I got these candy coated sprinkles for the cosmic brownie sprinkles.
How To Make
Full directions on how to make cosmic brownies are in the printable recipe card. This is a quick walk through on how to make them.
Step One: Start by preheating your oven, and greasing your 9×13 pan. Now you will add in your eggs, both sugars, vanilla, and salt.
Whisk your mixture together until creamy and well mixed.
Step Two: Now in a double boiler you will melt your chocolate and butter until fully melted and creamy. Make sure to stir often so it doesn’t burn.
Or you can do the microwave if you don’t have a double boiler. Just do 20 second intervals and stir in between each reheat.
Step Three: Now you will combine wet and dry ingredients together. Mix until it is well incorporated. Try not to over mix your brownie batter though.
Step Four: Bake your brownies as directed in the printable recipe card below. Once your brownies are cooled you can whip up the ganache, pour over the brownies. Then top with candy-coated sprinkles!
How Long Do Brownies Last
Store these rainbow brownies with sprinkles in the fridge. They will store for around 5 days.
You can eat them straight from the refrigerator chilled, or allow them to warm up to room temperature on the counter.
Cosmic brownies freeze really well. Simply place in an airtight container or freezer bag. These homemade cosmic brownies will freeze for about 2 months.
Just sit on the counter to thaw when you want to eat one! I pre-cut my brownies so I can grab just one or two out for the family.
- Make sure to not over mix your brownie batter. Whip up your ingredients until they are just combined. You want your brownies to be moist and chewy.
- Look to see if your brownies begin to pull from edges. That is a good sign your brownies are done. You can also do the toothpick test to see if they are fully cooked.
- Chocolate ganache is a bit different than a chocolate frosting. It is a thinner consistency and does take some time to harden up. You want your ganache to set a bit before you sprinkle your candy sprinkles over the chocolate brownies.
These little debbies brownies are such a winner. If you want something more than a classic brownie, this recipe might be the perfect treat for you and your family.
Cosmic Brownies are a chewy and thick brownie that is topped with chocolate ganache and topped with candy coated sprinkles.
An easy brownie recipe that you will want to make over and over again.
Little Debbie is the brand you can buy, or if you want to make homemade fudgy brownies like this recipe!
Brownies will pull away a bit from the edges of the pan. Then you will want to take a toothpick and stick in the center and lift up making sure there is no wet batter on the toothpick.
If you don’t want to make the frosting, go ahead and skip it. You can dust with a confectioner sugar or serve the brownies plain.
If you double this recipe you can reach for a larger pan or do 2 pans of brownies. Then you can bake at the same time if it fits in your oven or batch cook the fudge brownies.
