Monster Brownies

These monster brownies are loaded with peanut M&M’s and peanut butter M&M’s as well as chocolate chips. You can also add in pretzel pieces for a yummy salty bite that will extenuate the chocolate flavors!

These are decadent, indulgent and completely delicious! They are also super easy to make and the texture is soft and gooey just like a brownie should be. For a chewy brownie side, bake a little longer.

Add this brownie recipe to your baking repertoire:

This recipes is easy enough that you could memorize it. I fully think you should memorize it because everyone needs a good brownie recipe in their baking repertoire.

If you are nut allergy cautious:

While these monster brownies use peanut M&M’s and peanut butter M&M’s they can also be adapted to anyone who may have any nut allergies by using any other desired add in’s, like regular M&M’s, butterscotch chips, tahini swirled in or favorite candy add in’s.

What chocolate chips to use for the brownie batter:

I like to use milk and semi-sweet chocolate chips for the base of this brownie batter. I feel like that keeps it sweet but not overly sweet. If you prefer to have these all milk chocolate or all semi-sweet chocolate that is just fine too.
