What are Cosmic Brownies?
Cosmic brownies are made by Little Debbie. They are fudgy brownies topped with fudgy icing. They are topped with rainbow candy coated chocolate sprinkles.
I LOVED these brownies as a kid. So, I made this recipe based off those.
Ingredient Notes
- Dutch process cocoa powder- I used this one. Using dutch process cocoa powder gives the cookies a stronger chocolaty taste.
- Butter- Pull this out 2 hours before baking.
- Chocolate- I used Lindt 70% semi-sweet chocolate. Make sure to use a high quality chocolate. Don't use chocolate chips.
- Brown sugar- I used light brown sugar.
- Eggs- Pull these out 2 hours before baking.
- Egg yolk- The egg yolk makes them extra fudgy.
- Rainbow candies- Here is the ones I used.
Step By Step Instructions
Here is how to make and bake these cookies.
STEP 1: Melt the chocolate. First, melt the chocolate in the microwave. Let it cool slightly before mixing into the butter. Otherwise it will melt the butter if it was hot.
STEP 2: Mix dry ingredients. Use a sifter to sift the flour and cocoa powder.
STEP 3: Beat the butter and sugar. Beat the butter and sugars on high for 2 minutes to get it light and fluffy. Next, add in the melted chocolate. Beat on high for 1 minute.
STEP 4: Add in the wet ingredients. Then, add in the vanilla, eggs, and egg yolk. Beat on high for 1 minute to get it fluffy.
STEP 5: Mix in dry ingredients. Slowly mix these in. Mix just until combined. Then, chill the dough for 20 minutes.
STEP 6: Scoop the cookie dough. Use a 3 oz cookie scoop and scoop the dough. Bake 6 cookies per cookie sheet. Bake for 13-15 minutes. Cool completely before frosting.
STEP 7: Chocolate ganache. Make the chocolate ganache and let it sit on the counter to thicken. When the last batch of cookies go into the oven, place the chocolate in the fridge for 20 minutes to thicken.
STEP 8: Frost the cookies. Use ¾ tablespoon of chocolate ganache per cookie. Spread using an offset spatula and top with the rainbow candies.
Expert Tips
The cookies need a very short chill time. If they chill for a longer period, the chocolate will solidify and the cookies won't spread.
Scoop the dough and keep the cookie dough balls at room temperature while the others are baking.
When you are scooping, use exactly 3 oz of cookie dough.
FAQ
Yes you can. Bake for 9-11 minutes. I do recommend baking them bigger to get a fudgier center.
Yes it is! However, my cookie are extra fudgy!
For this recipe, I don't recommend this. Since the chocolate solidifies in the fridge, it doesn't bake the same.
Storing and Freezing
Store these cosmic brownie cookies at room temperature up to 5 days in an airtight container.
Freezing
Freeze the baked cookies in an airtight container and freeze up to 30 days. Thaw for 1-2 hours before eating.
