Peanut Butter M&M Chocolate Chip Cookies

There’s something undeniably magical about a warm cookie, straight from the oven, with melted chocolate puddles and a golden, crackly top. But when you toss in creamy peanut butter, mini M&Ms, and gooey chocolate chips? You’re not just baking cookies—you’re creating happiness.

These Peanut Butter M&M Chocolate Chip Cookies are a family favorite at my house. I started making them on a whim one rainy afternoon when I needed a pick-me-up, and now they’re practically a tradition. My kids call them “the fun cookies,” and I mean… fair enough. With pops of color from the M&Ms and that dreamy peanut butter-chocolate combo, they’re everything you want in a cookie—and then some.

What makes these cookies extra special is the texture. The peanut butter keeps them soft and chewy in the center, while the edges bake up golden and crisp. The chocolate chips melt into the dough, and the M&Ms give little bursts of crunch and sweetness. It’s a triple win: chewy, melty, and crunchy.

Perfect for lunchboxes, parties, bake sales, or just because you need a little joy (no judgment), this cookie recipe is easy, fun, and totally customizable. Plus, you don’t need a mixer—just a bowl, a spoon, and a cookie scoop if you’re fancy. Let’s get into it!

Ingredients

Here’s what you’ll need for cookie bliss:

• 1/2 cup (1 stick) unsalted butter, softened
  → Helps create that soft, buttery base. If using salted, reduce added salt by 1/4 tsp.
• 1/2 cup creamy peanut butter
  → For rich flavor and chewy texture. Natural peanut butter works if it’s stirred well and not too runny.
• 1/2 cup brown sugar, packed
  → Adds moisture and that caramely depth of flavor.
• 1/4 cup white sugar
  → For sweetness and crisp edges.
• 1 large egg
  → Binds everything together.
• 1 tsp vanilla extract
  → Adds warm, cozy aroma.
• 1/2 tsp baking soda
  → Gives the cookies lift and chew.
• 1/4 tsp salt
  → Balances the sweetness.
• 1 1/4 cups all-purpose flour
  → The perfect amount for thick, chewy cookies.
• 1/2 cup chocolate chips
  → Use semi-sweet, milk, or dark—your call.
• 1/2 cup mini M&Ms
  → For color, crunch, and a little fun!

Optional: Extra M&Ms or chips to press on top before baking (makes them extra pretty!).

Step-by-Step Instructions

1. Preheat Your Oven

• Set your oven to 350°F (175°C).
• Line a baking sheet with parchment paper or a silicone baking mat.

2. Cream the Butter and Sugars

• In a large mixing bowl, combine:
  • 1/2 cup softened butter
  • 1/2 cup creamy peanut butter
  • 1/2 cup brown sugar
  • 1/4 cup white sugar
• Use a hand mixer or sturdy spatula to mix until smooth and creamy—about 1 minute.

Tip: Make sure the butter is softened but not melted. Room temperature is perfect!

3. Add the Wet Ingredients

• Beat in:
  • 1 large egg
  • 1 tsp vanilla extract
• Mix until fully incorporated. The dough will look fluffy and slightly golden.

4. Add the Dry Ingredients

• Sprinkle in:
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 1 1/4 cups flour
• Stir until everything is combined. It’ll be a thick dough, but still soft and scoopable.

Don’t overmix here—just stir until the flour disappears!

5. Add Chocolate Chips and M&Ms

• Fold in:
  • 1/2 cup chocolate chips
  • 1/2 cup mini M&Ms

Save a few of each to press into the tops of the cookies for that Instagram-worthy finish.

6. Scoop and Shape

• Use a 1.5 tbsp cookie scoop or a spoon to form dough balls.
• Place them on your baking sheet about 2 inches apart—they’ll spread a little.
• If you want picture-perfect cookies, press a few extra M&Ms and chocolate chips into the tops before baking.

7. Bake

• Bake for 10–12 minutes, until the edges are just golden and the centers look slightly underbaked.

They’re done when: The edges are set, and the centers look puffy but soft. Don’t wait for them to look completely baked—they’ll firm up as they cool!

8. Cool

• Let cookies rest on the pan for 5 minutes.
• Transfer to a wire rack to cool completely… or eat one warm with a glass of cold milk. No judgment.

How to Serve

These cookies are perfect warm, cooled, or even frozen (more on that later!). Here are some fun ways to serve them:

• Classic: With a tall glass of cold almond milk or oat milk.
• Party Style: Stack them on a colorful platter for birthdays or celebrations.
• Ice Cream Sandwiches: Sandwich a scoop of vanilla or chocolate ice cream between two cookies.
• Lunchbox Treats: Pop one in a lunchbox or snack bag for a sweet midday surprise.
• Cookie Jar Goals: Store in a glass jar on the counter for easy snacking.

Additional Tips

1. Don’t overbake: These cookies continue baking on the sheet. Pull them out when they look slightly underdone in the center.
2. Chill for thicker cookies: If you want puffier cookies, chill the dough for 30 minutes before baking.
3. Use a cookie scoop: Helps your cookies bake evenly and look bakery-perfect.
4. Mix up the candy: Swap mini M&Ms for peanut M&Ms, Reese’s Pieces, or even chopped chocolate.
5. Press extra toppings: Always press a few extra M&Ms and chips on top before baking. It makes a huge difference in presentation!

FAQ

1. Can I use crunchy peanut butter?
Totally! Just know your cookies will have more texture. Yum!

2. Can I skip the M&Ms?
Sure. You can use more chocolate chips, chopped nuts, or other candy pieces.

3. What if I only have salted butter?
No problem—just reduce the added salt to 1/8 tsp or omit it.

4. Can I use natural peanut butter?
Yes, but make sure it’s stirred well and not too runny. You may need to add an extra tablespoon of flour.

5. How do I keep the cookies from spreading too much?
Chill the dough for 30 minutes if your kitchen is warm, or your butter was very soft.

6. What size M&Ms work best?
Mini M&Ms work best because they distribute evenly and don’t overpower the cookie. But regular-sized ones are fun too!

7. Can I make these dairy-free?
Yes! Use a plant-based butter and dairy-free chocolate chips.

8. Can I double the recipe?
Yes, and I recommend it—you’ll want extras! Just use two baking sheets and rotate halfway through.

Yep! Store it in the fridge for up to 3 days or freeze as cookie dough balls.

10. How long do these cookies stay soft?
Stored properly, they’ll stay soft for about 4–5 days. Add a slice of bread to the container to help retain moisture.
