Step‑by‑Step Instructions for Soft & Chewy Peanut Butter M&M Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats up, line a baking sheet with parchment paper to prevent the cookies from sticking. This simple preparation ensures even baking and easy cleanup, making the process of making your Soft & Chewy Peanut Butter M&M Cookies a breeze.
Step 2: Mix the Peanut Butter and Sugars
In a large mixing bowl, combine ¾ cup of creamy peanut butter with ½ cup of brown sugar and ½ cup of granulated sugar. Use a hand mixer or a wooden spoon to blend the ingredients together until the mixture is light and fluffy, taking about 2-3 minutes. The fluffy texture is key to getting that melt-in-your-mouth consistency.
Step 3: Incorporate the Egg and Vanilla
Add 1 large egg and 1 teaspoon of vanilla extract to the peanut butter mixture. Beat them in until well combined, ensuring the mixture is smooth and uniform. This step will bind your Soft & Chewy Peanut Butter M&M Cookies, so take your time to mix thoroughly for about 1-2 minutes.
Step 4: Add Baking Soda and Salt
Sprinkle in 1 teaspoon of baking soda and a pinch of salt to your wet ingredients. Fold them gently with a spatula until just combined; be careful not to overmix. This will help the cookies rise beautifully while balancing the sweetness, allowing the flavors to shine through in each bite.
Step 5: Fold in the M&M’s
Now, gently fold in 1 cup of colorful M&M’s into the cookie dough. Ensure they are evenly distributed throughout the mixture, creating spots of vibrant color in your dough. Reserve a few M&M’s for topping the cookies later. This will enhance the visual appeal of your Soft & Chewy Peanut Butter M&M Cookies once baked.
Step 6: Scoop and Shape the Dough
Using a cookie scoop or tablespoon, drop rounded dough balls onto the prepared baking sheet, spacing them about 2 inches apart. With your fingers or the back of a spoon, gently flatten each dough ball for even baking. Remember to sprinkle the reserved M&M’s on top for that finishing touch before baking.
Step 7: Bake the Cookies
Transfer the baking sheet to your preheated oven and bake for 8-10 minutes. Keep a close eye on them; the edges should be set while the centers appear slightly underbaked. This contrast ensures your Soft & Chewy Peanut Butter M&M Cookies remain soft and delicious, just as they should be.
Step 8: Cool and Enjoy
Once baked, allow the cookies to cool on the baking sheet for about 5 minutes. This resting time will help them firm up slightly without losing their delightful softness. Carefully transfer them to a wire rack to cool completely. Enjoy your wonderfully inviting Soft & Chewy Peanut Butter M&M Cookies with a glass of milk or your favorite beverage!
Storage Tips for Soft & Chewy Peanut Butter M&M Cookies
Room Temperature: Store your cookies in an airtight container at room temperature for up to 1 week to keep them fresh and chewy.
Freezer: For longer storage, freeze cookie dough balls. Place them in a single layer on a baking sheet, then transfer to an airtight container once frozen. They can stay in the freezer for up to 3 months.
Reheating: When ready to enjoy, bake frozen dough balls directly from the freezer for an extra fresh taste, adding a couple of minutes to the baking time.
Make-Ahead: Consider making a double batch of these Soft & Chewy Peanut Butter M&M Cookies to enjoy a delightful treat anytime your sweet tooth strikes!

Soft & Chewy Peanut Butter M&M Cookies Recipe FAQs
How do I choose the right peanut butter for these cookies?
Absolutely! For the best results, use creamy peanut butter. It gives your cookies a rich texture that blends beautifully. If you need a nut-free option, sunflower seed butter works wonderfully without sacrificing flavor!
How should I store my cookies to keep them fresh?
Store your Soft & Chewy Peanut Butter M&M Cookies in an airtight container at room temperature for up to 1 week. If you need longer storage, freeze them! Arrange the cookies in a single layer, separating them with parchment paper, to prevent sticking, and keep them in an airtight container for up to 3 months.
Can I freeze the cookie dough for later baking?
Absolutely! To freeze the dough, scoop out cookie balls and place them on a baking sheet lined with parchment paper. Freeze until firm, then transfer them to an airtight container, separating layers with parchment. When you’re ready to bake, just pop the frozen dough directly on the baking sheet and add a couple of extra minutes to the baking time. It’s that easy!
What if my cookies turn out too hard or dry?
Very! If your cookies are coming out hard, it might be due to overbaking. Keep a close eye on them and take them out when the edges are set but the centers are still slightly underbaked; they’ll firm up as they cool. Another helpful tip—make sure to measure your ingredients accurately, as too much flour can lead to dryness.
Are there any dietary considerations I should keep in mind?
Of course! If you’re catering to allergies, remember to consider any nut sensitivities. For a nut-free version, swap peanut butter for sunflower seed butter. For vegan options, replace the egg with a flax egg (1 tbsp flaxseed meal + 2.5 tbsp water) to maintain the lovely texture while keeping it plant-based.
