Chocolate Candy and Marshmallow Easter Brownies

The marshmallows add to the sweetness to destroy the cravings of the sweetest of sweet tooths (sweet teeth?). 

Here we show the Spring or Easter colored M&M candies.

Of course, change them up depending on the holiday or season.

You could also use Peeps instead of regular marshmallows if you’d like an Easter explosion brownie.

Recipe notes and FAQ

Do marshmallows burn in the oven?

Don’t top your brownies with marshmallows before baking unless you want marshmallow goo on top of your brownies. They will melt in the oven. That’s why we only put them back in the oven for a short time.

Can I use milk instead of water for brownies?

Yes. Using milk instead of water will make the brownies more rich.

What is the best brownie mix?

The Spruce Eats ranked Ghirardelli Chocolate Triple Fudge Premium Brownie mix as the best overall, while Betty Crocker Delights Triple Chunk Supreme Brownie Mix took best value. 

Why do brownies crack?

If your brownies are cracked and sunken in the middle, you stirred the batter too much. Over mixing adds too much air to the batter. 

Yield: 20 brownies
