Preparation Phase & Tools to Use

To make these cookies effortlessly, you’ll need a few basic kitchen tools:

• Mixing Bowls – Use one large and one medium bowl for wet and dry ingredients. A wide bowl makes creaming peanut butter and sugar easier.
• Electric Hand Mixer or Stand Mixer – Essential for thoroughly creaming the peanut butter, butter, and sugars until fluffy.
• Measuring Cups and Spoons – Precision is key in baking, so accurate measurements matter.
• Rubber Spatula – Helps in folding in the M&Ms and scraping down the sides of the bowl.
• Cookie Scoop – Ensures evenly sized cookies for consistent baking.
• Baking Sheet – A sturdy, non-stick or parchment-lined sheet allows for even cooking and easy cleanup.
• Cooling Rack – Prevents cookies from becoming soggy by allowing air circulation underneath.

Preparation Tips

Make sure your butter is softened but not melted — this helps in creating a light and fluffy mixture when creamed with the peanut butter and sugars. Don’t overmix the dough once you add the dry ingredients; doing so can make the cookies tough. When folding in the M&Ms, do it gently to avoid breaking them. For picture-perfect cookies, press a few extra M&Ms on top of the dough balls just before baking. Lastly, chilling the dough for 30 minutes helps the cookies hold their shape and enhances the flavor.

Ingredients for this Christmas M&M Peanut Butter Cookies

• 1/2 cup unsalted butter, softened
• 1/2 cup creamy peanut butter (not natural)
• 1/2 cup granulated sugar
• 1/2 cup packed light brown sugar
• 1 large egg
• 1 tsp vanilla extract
• 1 1/4 cups all-purpose flour
• 1/2 tsp baking soda
• 1/4 tsp baking powder
• 1/4 tsp salt
• 1/2 cup semi-sweet chocolate chips
• 3/4 cup red and green holiday M&Ms (plus extra for topping)

---

Step 1: Cream the Butters and Sugars

In a large mixing bowl, cream together the softened butter and peanut butter until smooth and well combined. Add in both the granulated sugar and brown sugar. Beat the mixture using an electric mixer on medium speed until it becomes light and fluffy, about 2–3 minutes.

---

Step 2: Add the Egg and Vanilla

Crack in the egg and pour in the vanilla extract. Continue beating until everything is fully incorporated and the mixture is smooth.

---

Step 3: Combine Dry Ingredients Separately

In a separate bowl, whisk together the flour, baking soda, baking powder, and salt. This ensures even distribution of leavening agents throughout the dough.

---

Step 4: Mix Dry and Wet Ingredients

Gradually add the dry ingredients into the wet mixture. Mix on low speed or use a spatula to combine until just incorporated. Be careful not to overmix — a few streaks of flour are fine at this stage.

---

Step 5: Fold in the Chocolate Chips and M&Ms

Gently fold in the semi-sweet chocolate chips and holiday M&Ms using a spatula. To keep the M&Ms from breaking apart, avoid using the mixer in this step.

---

Step 6: Chill the Dough

Cover the bowl with plastic wrap and refrigerate the cookie dough for at least 30 minutes. This helps prevent the cookies from spreading too much while baking and enhances their texture.

---

Step 7: Preheat and Prep the Oven

While the dough chills, preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat to avoid sticking and ensure even baking.

---

Step 8: Scoop and Shape the Dough

Use a medium cookie scoop (about 1.5 tablespoons) to portion out dough balls and place them 2 inches apart on the prepared baking sheet. If desired, press a few extra M&Ms on top of each dough ball for a festive look.

---

Step 9: Bake to Perfection

Bake in the preheated oven for 9 to 11 minutes. The edges should be slightly golden, while the centers may look slightly underdone — they will continue to set as they cool.

---

Step 10: Cool and Enjoy

Remove the cookies from the oven and allow them to cool on the baking sheet for 5 minutes before transferring to a wire rack. Serve warm or let them cool completely before storing.

---

Notes

For the richest flavor and best texture, stick with creamy peanut butter that’s not labeled “natural”—natural versions can make the dough too oily or crumbly. Chilling the dough is optional but highly recommended for a more uniform, thick cookie with better flavor. Always underbake slightly and let them finish cooking on the baking sheet to keep the centers soft and chewy.

---

Watch Out for These Mistakes While Cooking

• Using natural peanut butter: This often results in dry, crumbly cookies due to the separation of oil.
• Skipping the chilling phase: Not chilling the dough can lead to cookies spreading too much and losing their thick, chewy centers.
• Overbaking: These cookies should look slightly underbaked when they come out—overbaking will make them dry and hard.
• Adding M&Ms too early: Mixing M&Ms with an electric mixer can crush them; always fold them in gently by hand.
• Crowding the baking sheet: This can cause cookies to bake unevenly. Always leave space for spreading.

Storage Instructions

Once cooled completely, store the cookies in an airtight container at room temperature for up to 5 days. For longer storage, freeze the cookies in a single layer on a baking sheet until solid, then transfer to a zip-top freezer bag or airtight container. They’ll keep well for up to 3 months. To enjoy later, let them thaw at room temperature or warm in the microwave for about 10 seconds.

Frequently Asked Questions

Can I use crunchy peanut butter instead of creamy?

Yes, you can, but it will change the texture of the cookies slightly by adding more crunch. Creamy peanut butter gives the smoothest and most even texture.

Do I need to chill the dough?

It’s not absolutely required, but chilling helps the cookies hold their shape better and enhances the flavor. It’s highly recommended if you have the time.

Can I freeze the dough instead of the baked cookies?

Absolutely! Scoop the dough into balls, freeze them on a tray, then store in a freezer bag. Bake directly from frozen—just add 1-2 minutes to the bake time.

How do I make these gluten-free?

Use a 1:1 gluten-free all-purpose flour blend. Make sure your other ingredients, like M&Ms and peanut butter, are also certified gluten-free.

Can I double the recipe?

Yes! This recipe doubles well. You may need to bake in batches depending on your oven size.

What’s the best way to make cookies the same size?

Use a medium cookie scoop or weigh the dough balls with a kitchen scale to ensure even size and baking.

Why are my cookies dry?

Dry cookies can result from overbaking or measuring flour incorrectly. Spoon and level your flour instead of scooping straight from the bag.

Are these safe to gift or ship?

Yes, once fully cooled, these cookies ship well! Package them in a snug container with parchment paper between layers.
