How To Make

Step 1: 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 2: 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 3: 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 4: 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.

Can You Freeze

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.

Tips For Making Homemade Brownies

  • 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.

Ingredients

Brownie

  • 1 cup granulated sugar

Chocolate Ganache Glaze

  • 4 Tablespoons unsalted butter softened
  • 8 ounces semisweet chocolate chips 
  • 1/2 cup sweetened condensed milk

Topping

  • ¼ cup rainbow Chocolate Chips

Instructions

  1. Start by preheating your oven to 350 degrees Farenheit. Then place parchment paper in your 9x13 pan on bottom and sides then spray cooking spray to prevent sticking.
  2. In a stand mixer or bowl whip up your granulated sugar, brown sugar, whole eggs and yolks, vanilla, and salt. Mix until creamy.
  3. Now in a double boiler or microwave melt your butter ahd chocolate together for the fudge brownies. Once it is melted whisk in your vegetable oil.
  4. Pour the chocolate mixture into your sugar mixture and mix until it begins to combine. Slowly stir in all purpose flour and cocoa powder.
  5. Pour your easy fudge brownies into your baking pan, and cook for 25-35 minutes or until done. Stick a toothpick in your brownies to see if the toothpick comes out clean.
  6. While your brownies are cooking you can work on your chocolate ganache glaze. Grate your chocolate into a heatproof bowl and set aside.
  7. Now you will add sweetened condensed milk and butter in another bowl and heat up in the microwave or a double boiler. You want it to melt. Stir frequently. I did every 30 seconds in the microwave stirring in between.
  8. When the butter is melted add in your chocolate chips, and stir until they are all melted.
  9. Once your brownies are done, pour over the ganache, and your rainbow chip sprinkles.
  10. Let your brownies cool completely before you try to remove and slice.
