My parents theory for us girls was always keep us busy, and keep us out of trouble. Their updated take on idle hands make the devil’s work, I guess.

I’ve got to say though, they’re track record speaks for itself, and the hubs and I’ve pretty much applied the same philosophy to the sons, keeping them enrolled in extra curricular activities.

But my, my how times have changed. Or more specifically, how post game snack times have changed.

Back in the day everybody looked forward to the post game snacks and seeing what dreamy sweet cakes were waiting for us. Complete with a perfectly acceptable sugar-laced juice drink of some sort.

If you brought oatmeal cream pies, it was a great post game, regardless of the win or loss. But if you brought cosmic brownies? It was a great game, most likely a championship of some sort.

Now-a-days the sons get carrot sticks or bananas post game, or even outrageously expensive, and overly stuffed organic snack bags with several different options to choose from.

And I get it, I do.

Of course there little bodies need to refuel, but every kid (at least once in their lives) deserves to experience the sheer joy of biting into a fudgey brownie, topped with chocolate ganache, and studded with fun candy-coated, rainbow-colored chocolate candies.

Yep, I was that mom on snack day. And no I didn’t pair them with bottled water, or little organic juice drinks. Capri Sun all day. Erry day.

And damn if those kids didn’t think it was magic. Even the sons (who’re used to sweet treats) were a bit in awe.

I even brought enough to share with the parents. You can’t be stingy with something this great. And I happily shared the recipe with each and every one who asked for it. Now I’m sharing the love with all of you too.

For the Brownies

  • 3/4 cup butter 1½ Sticks
  • 2 eggs
  • 1 cup sugar
  • 2/3 packed cup light brown sugar
  • 2 tbsp milk
  • 2 tsp vanilla extract
  • 3/4 cup unsweetened cocoa powder
  • 3/4 cup all-purpose flour

For the chocolate ganache topping:

  • 1 1/2 cups semi sweet chocolate chips
  • 1/2 cup heavy cream
  • 1 cup M&M minis or rainbow chocolate chip candies


  • Line an 11×7 inch pan with foil. Spray with non stick spray.
  • In a large bowl, melt butter in the microwave for 1-2 minutes, or melt in a small pot over low heat and then transfer to the bowl.
  • Whisk in the sugars, eggs, milk, and vanilla. Then whisk in the cocoa powder until the batter is smooth and not lumpy.
  • Add flour gradually, stirring until everything’s evenly combined.
  • Pour the batter out into the prepared pan, and use a spatula to gently spread it out evenly. Bake at 350 degrees for 25-30 minutes or until a toothpick inserted in the center comes out clean. Allow it to cool completely.
  • Heat the heavy cream in a medium sauce pan over medium-medium low heat. Add in the chocolate chips, stirring occasionally until they’ve both completely incorporated and the ganache is smooth.
  • Pour the ganache over the completely cooled brownies. Smooth it out with an offset spatula.
  • Sprinkle the M&Ms, or rainbow chocolate chip candies, over the top of the ganache. Refrigerate until the ganache has set. Cut brownies into squares to serve and enjoy!

  1. It’s great how you’re trying to recreate dishes so your family can have some of the same memories that you had growing up. And, these look delicious as well! Happy FF, and have a wonderful weekend!

  2. I would definitely be that parent too! Of course kids need healthy foods, but treats are good too! These look soooo good, I’ve never actually had a cosmic brownie, I feel very deprived!
