Peanut Butter M&M Blondies

The perfect combination of M&Ms and Peanut Butter make these blondies a perfect dessert! We love to serve them warm with a scoop of ice cream fresh out of the oven.

Sometimes I just want peanut butter and M&Ms (okay not sometimes… I want them everyday).

I decided to make something fast and easy so I could have these two amazing ingredients together.

I served some right out of the oven with some ice cream on top. With the rest, I let them cool and then ate them the next day!

We aren’t huge chocolate lovers at our house, so having a peanut butter cookie with just the right amount of chocolate made these the perfect dessert.

What are blondies?

Haven’t heard of blondies? Welcome to a whole new world of dessert!

Blondies are basically the non-chocolate version of brownies. Most blondies have a sugar, peanut butter, or plain base with delicious fillings.

The consistency of a blondie is a lot different than a cookie. Definitely more on the gooey and delicious bar side of desserts.

We make these constantly at our house! Between the six of us, we have a large variety of blondies. Here are just a few of our favorites you HAVE to check out!

  • Butterfinger Blondies: Pretty similar with a peanut butter base, but stuffing these full of crushed up butterfingers makes for a delicious treat.
  • Easy Snickerdoodle Blondies: Would you believe me if I told you these only had 6 ingredients? SO yummy!
  • Cake Batter Blondies: Would it really be a dessert from Six Sisters’ Stuff if we didn’t have the cake batter version? Equally as delicious with minimal ingredients.

How to make Peanut Butter M&M Blondies:

Let’s get baking! Here are the step by step instructions on making our Peanut Butter M&M Blondies:

  1. Preheat oven to 350 degrees and line an 8×8 baking dish with parchment paper or aluminum foil and lightly grease with cooking spray.
  2. In a large bowl, combine the melted butter and light brown sugar. Mix thoroughly. Add in the egg and vanilla extract.
  3. Mix in the peanut butter and make sure all of the wet ingredients are thoroughly mixed.
  4. Add in the salt and flour. Then gently mix in 1 cup of M&M’s.
  5. Spread the brownie mixer in the baking dish and spread out evenly with a plastic spatula.
  6. Sprinkle 1/2 cup of M&M’s on top and press into the batter.
  7. Bake for 20-25 minutes or until a toothpick inserted in the middle comes out clean.

Bakers Notes:

If you’d like to double this recipe, we recommend doing so in a 9×13” pan, rather than a cookie sheet. This will keep them thick and chewy.

This particular recipe does NOT call for baking powder or baking soda. It may seem odd, but these will turn out just fine without!

We used Mini M&M’s in this recipe, but regular M&M’s work great. You could also substitute Reese’s pieces or another favorite chocolate candy.

We’d recommend letting these cool for about 20 minutes before cutting them up, if you want them to keep their shape. For a delicious dessert, scoop them out 5 minutes after baking and top them with ice cream.

  1. Disappointed in this recipe. I am a good baker and mine I did in an 8x8 Pyrex pan, lined with foil and after 40 minutes of baking took them out because my toothpick came out clean, cut them and the very outer edges crumble and the rest seems underbaked. Is this how a blonde should be?
    • We use store brand (Kroger) and name brand peanut butter in this recipe. They all work the same. We usually buy Jif or Skippy when buying the store brand. We haven't used natural peanut butter in this recipe, so we aren't sure how the outcome would be with that.
