Peanut Butter Pretzel M&M Fudge

Remember when I made delicious Pretzel-Topped Mac & Cheese using a 3/4-full bag of pretzels leftover from a previous recipe? Well folks, this is that recipe. I wanted to make a super simple fudge, and I was craving peanut butter. But you know me; plain old peanut butter fudge doesn’t cut it. So then, I thought of Monster Cookies and their delicious trio of PB, pretzels, and M&M’s. Immediately, I knew that was it: Peanut Butter Pretzel M&M Fudge.

It’s a mouthful to say, so save your breath and stuff your pie hole with this fudge instead. It’s creamy, rich decadence with a trifecta of flavors coming together. The peanut butter and pretzels preform a salty tango while the chocolatey M&M’s sings a sultry, sweet tune for them to dance to. Everything works together in the most delicious way. Plus, you’re getting textural teamwork too: creamy fudge + the crispness of the pretzels + the crunch of the M & M’s exterior. Who knew you could have such complexity in a 6-ingredient, 5-minute fudge recipe?

Yes, those numbers are correct. We’re talking the simplest fudge recipe ever. You don’t need a candy thermometer; in fact, you don’t even need a stove. All you need is a microwave. Sounds impossible? I promise it’s not. You can have creamy, luscious fudge from your microwave in just a few minutes, and no one but you will ever know! Everyone else will think you’re Willy-freakin-Wonka.

Go make some of this fudge and show Mr. Wonka how it’s done.

A Few Tips Before You Get Cooking:

  1. This would still be delicious in a standard chocolate fudge recipe.
  2. This fudge freezes great. Wrap in cling wrap then store in an air-tight container and freeze.
  3. Use dark chocolate M&M’s if you prefer.
  4. If you don’t push the M&M’s and pretzels down into the fudge good, they won’t adhere well. It’s not the end of the world, but they’ll be quite messy to eat.
  5. Don’t skip the parchment paper, or you will never get this fudge out of the pan!

Peanut Butter Pretzel M&M Fudge
Adapted from Alton Brown’s Peanut Butter Fudge


  • 8 ounces unsalted butter, plus more for greasing pan
  • 1 1/2 cups smooth peanut butter
  • 1 teaspoon vanilla extract
  • 1 pound powdered sugar
  • 1/4 cup M&M’s
  • 16 crunchy pretzels twists


  1. Butter an 8×8-inch pan and line with parchment paper or wax paper.
  2. Combine the butter and peanut butter in a 4-quart microwave-safe bowl and cover. Microwave for 1 minute on high. Stir and microwave on high for 2 more minutes (Use caution when removing this mixture from the microwave, it will be very hot.) Add the vanilla and powdered sugar to the peanut butter mixture and stir to combine with a wooden spoon. The mixture will become hard to stir and lose its sheen. Spread into prepared pan. Immediately top with M&M’s and pretzels, pressing them into the fudge. You may swirl it in too if you like.
  3. Fold the excess parchment paper so it covers the surface of the fudge and refrigerate until cool, about 2 hours. Cut into pieces and store in an airtight container at room temperature for up to a week.
