This goes really well with Hot Chocolate Starbucks CopyCat Recipe if you are feeling decadent and want to totally surprise the kids. My kids have been known to even dunk their brownie into hot chocolate! Can you tell we are big chocolate fans around here?
Ok, let’s get started because I have a feeling you will be hooked!

Let’s get started making Cosmic Brownies Copycat Recipe

Ingredients:
- Fudge brownies
- semi-sweet chocolate chips
- heavy whipping cream
- Mini M&M’s or M&M’s

How to make cosmic brownie recipe:
1. First, go ahead and make the brownies according to the box mix instructions.

2. Second, bake the brownies and let cool completely.
3. Next, while the brownies are cooling, make the fudge topping. Heat up the whipping cream in a sauce pan. I like to do this over medium heat. Pour the chocolate chips into the the cream and stir until they are melted and the mixture is smooth.
4. Now it is time to pour that delicious chocolate mixture all over the top of the brownies. I use a spatula to get a smooth top. If you like chocolate ganache, you will love this.

It is pretty simple to get the icing smooth. The spatula helps to smooth out any wrinkles or places that still need icing.
5. Finally, sprinkle the M&M’s on the top of the icing! Make sure to do this right away so the chocolate will stick to the brownies. Put the brownies in the fridge so they can set. This takes about an hour and then you can serve the cooled brownies.
Yum!

We love homemade cosmic brownies but this icing is equally delicious on cake as well. Yum! One bite and you will be hooked because they are just like the ones from the grocery store. I think they are actually better!

- You could even use seasonal M&M’s to make these for different holidays. Pretty pastels for Easter, pinks for Valentine’s Day, Red and Green for Christmas… There are so many options you can make.

This icing is so good and combined with the brownies, it’s even better. One batch goes pretty quickly at my house so I like to double the recipe. That way we have one pan to eat at home for dessert or after school snacks.
I use the other batch to cut into squares and pop into sandwich bags. This is perfect for school lunches and I can just grab and go in the mornings. My kids are super excited to have this fun treat in their lunch box and I’m happy that I was able to make it at home.
Brownies are always a hit. We also love this homemade butterscotch brownies recipe for another tasty brownie to try.
