Ingredients You’ll Need

Here’s what to pull from your pantry before you get started:

• Shortening
• Vanilla extract
• Granulated sugar
• Brown sugar
• Large egg
• Creamy peanut butter
• All-purpose flour
• Baking soda
• Kosher salt
• Plain M&Ms

These measurements are forgiving, so don’t stress about getting everything exact. The real magic happens when the peanut butter and sugars cream together into a smooth, creamy base.

How to Make Peanut Butter M&M Cookies

Follow these simple steps for perfect cookies every time:

1. Preheat your oven to 350°F and line two cookie sheets with parchment paper.
2. Cream the shortening, vanilla, granulated sugar, and brown sugar in a large bowl until smooth, about 2 minutes. Add the egg and beat until combined. Scrape down the sides, then add the peanut butter and mix well.
3. Whisk the flour, baking soda, and salt together in a separate bowl. Add the dry ingredients to the peanut butter mixture and stir until just combined. Fold in 1/2 cup of M&Ms.
4. Scoop the dough using a #60 cookie scoop or a tablespoon, and place balls onto the prepared sheets. Press a fork into the top of each cookie to create a crisscross pattern.
5. Bake for 8–10 minutes, or until the edges are lightly golden and the tops feel firm. Remove from the oven and press additional M&Ms into the tops if you’d like that extra pop of color and chocolate in every bite.
6. Cool on the baking sheet for about 5 minutes, then transfer to a wire rack to cool completely.

The secret to great peanut butter cookies is not overbaking them. Pull them out when the edges just start to turn golden — they’ll continue to set as they cool on the sheet.

Recipe Variations to Try

Once you’ve nailed the classic version, feel free to mix things up:

• Stir in a handful of semi-sweet chocolate chips alongside the M&Ms for double the chocolate.
• Swap in Peanut Butter M&Ms or mini M&Ms for a different texture and flavor.
• Use a larger cookie scoop for giant cookies — just add a couple of extra minutes to the bake time.
• Sprinkle a tiny pinch of flaky sea salt on top right after baking for a sweet-and-salty contrast.

Frequently Asked Questions

How Do I Store Peanut Butter M&M Cookies?

Keep them in an airtight container at room temperature for 3–5 days. They stay soft and chewy for days, though honestly, they rarely last that long in our house.

Can I Freeze These Cookies?

Absolutely. Once the cookies have cooled completely, place them in a freezer-safe bag or airtight container and freeze for up to 3 months. Thaw at room temperature for a few hours or overnight. They taste almost as fresh as the day they came out of the oven.

Can I Make the Dough Ahead of Time?

Yes! You can prepare the dough, cover it tightly, and refrigerate for up to 48 hours. For longer storage, scoop the dough balls onto a cookie sheet, freeze them for about an hour until firm, then transfer them to a freezer bag. Bake straight from frozen — just add a minute or two to the baking time.

This make-ahead approach is a lifesaver when you want fresh-baked cookies without the last-minute rush.
