Copycat Cosmic Brownies

Copycat Cosmic Brownies

With how much baking we do in my house it’s ironic that my son’s favorite dessert of all time is Cosmic Brownies.  You know.  The store bought ones.  What the heck?!?!  I can’t really blame him, though.  I remember as a kid growing up thinking the best “treat” was a store bought cake.  My Mom was constantly making delicious desserts so it truly was a treat to get something store bought.  Now I just shake my head because there’s not a whole lot of store bought bakery items that I would want to eat.  Give me homemade any day.

So I can’t fault my son (I suppose.)  But I can help out by making Copycat Cosmic Brownies.  Right?!  The best of both worlds.

These brownies are chocolate overload.  My co-workers loved them.

The brownie is a rich, chocolatey brownie layer.

Then you add a rich chocolate ganache and sprinkle with mini M&Ms.

The next time I make this I’m going to use a bigger pan.  I think a 9×9 pan makes them too thick.  Don’t get me wrong.  They’re delicious.  But if you want a true Cosmic Brownie, they need to be thinner.  And the ganache frosting recipe made a lot.  I didn’t end up using it all and look how much is on there.  I think if the brownies were made in a larger pan, it would have been perfect.
