It’s no secret I love recreating my favorite childhood treats.

Sure, I could easily buy a package (or ten…I am an adult!) whenever I want, but where is the fun in that? There are many benefits in making your favorite treats at home, and some of my go-to recipes include Cadbury creme eggs, kit kat bars, and cosmic brownies.

What are Cosmic brownies? 

Cosmic brownies are a pre-packaged dessert by Little Debbie’s, who are famous for other packaged sweets like powdered donuts, mini muffins, and sweet rolls.

While fun and delicious to eat, they are full of processed and artificial ingredients, and full of hydrogenated oils and sugar. Instead of reaching for one, take a few minutes to make your own at home!

Why this cosmic brownie recipe will be a dessert favorite-

  • No flour or grains needed. No flour (white, coconut, almond, or oat) is needed! 
  • Made in just one bowl. This means the clean up at the end is minimal! 
  • Diet friendly. There are options to make these brownies lower carb, vegan friendly, and/or gluten free. 

What I love about these brownies is how perfect the texture is- Fudgy, gooey, and with a thick layer of rich frosting. After trying one of these, you’ll never look at a Little Debbie Brownie again!

What is a cosmic brownie made of?

The Ingredients.

  • Chocolate– Any semi-sweet or dark chocolate works. I like using 80% Lindt chocolate, as it is lower in sugar and has no dairy in it. 
  • Butter– From a stick or block, not a spread. 
  • Sugar– White sugar is preferred, but brown or coconut sugar works. 
  • Eggs– Room temperature. 
  • Cocoa powder– Unsweetened and sifted well,  to ensure there are no clumps. 
  • Chocolate frosting– Skip the expensive store bought or pre-made kind and make a simple 2 ingredient frosting
  • Candy buttons– Any candy works!

The Instructions. 

Start by adding the chocolate and butter into a microwave-safe bowl and microwaving in 30-second ingredients until the butter has melted. Whisk together until smooth. Next, add the sugar then the eggs, one at a time, before stirring through the cocoa powder until completely combined.

Now, transfer the batter into a greased pan and bake 25-30 minutes, or until a toothpick comes out the center mostly clean. Let the brownies cool completely, before adding the frosting and the candy buttons. Slice the brownies and serve immediately.

Dietary swaps and substitutions

  • Make them vegan. Swap out the eggs for vegan substitutes, like flax eggs, aquafaba, or an egg replacement. 
  • Cut the carbs. Use sugar free chocolate chips and a brown sugar substitute. For the frosting, use a keto chocolate frosting
  • Keep them gluten free. Use gluten free candy buttons. 
  • Swap out the dairy. Dairy free chocolate and dairy free butter work beautifully for these brownies. 

Storing and freezing instructions

  • To store: Leftovers can be stored at room temperature, covered, for up to five days. If you’d like these brownies to keep longer, store them in the refrigerator. 
  • To freeze: Place the baked and frosted brownies in an airtight container and store them in the freezer for up to 6 months.

    Delicious, very rich, and fudge-like. A small piece can go a long way.

    We enjoyed the contrasting textures of the “brownie” layer and the frosting. If refrigerated, definitely tastes and feels like fudge.

    Very easy to prepare. Beware. The candy coating may run when it contacts the moisture in the frosting. Not exactly visually appealing the longer it sits. Consider adding right before serving.

  2. if i switch out the pumpkin for banana or sweet potato like you suggest, do i need to change any other part of the recipe?

    Hello ~ Thank you for the recipe. Why does the coconut milk need to be chilled since we are heating it up to use it? Thanks so much!
