Step‑by‑Step Instructions for Peanut Butter M&M Chocolate Chip Cookies
Step 1: Prep oven and pans
Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper. This will ensure your cookies bake evenly and don’t stick. As the oven heats, you’ll have time to gather your ingredients and prepare the batter, so everything is ready when you need it.
Step 2: Mix dry ingredients
In a medium-sized bowl, whisk together 2 ½ cups of all-purpose flour, 1 teaspoon of baking soda, and ½ teaspoon of salt. This combination provides the structure and flavor balance for your Peanut Butter M&M Chocolate Chip Cookies. Once thoroughly mixed, set the bowl aside, allowing the flavors to blend while you tackle the wet ingredients.
Step 3: Cream butter and sugars
In a large mixing bowl, cream together ½ cup of softened unsalted butter, ¾ cup of brown sugar, and ½ cup of granulated sugar using a hand mixer or stand mixer. Beat on medium speed until the mixture is light and fluffy, which should take about 2-3 minutes. This step adds air to the dough, creating that delightful texture we crave in cookies.
Step 4: Incorporate peanut butter
Add 1 cup of well-stirred peanut butter to the creamed mixture, mixing until fully combined and smooth. This step infuses your cookies with rich peanut buttery goodness. You’ll want to make sure the peanut butter is well blended to achieve a uniform flavor throughout your Peanut Butter M&M Chocolate Chip Cookies.
Step 5: Add egg and vanilla
Beat in 1 room temperature egg and 1 teaspoon of pure vanilla extract, ensuring everything is well integrated. Mix for about a minute on medium speed until the egg is fully absorbed, creating a cohesive batter. The vanilla will enhance the sweetness and round out the delicious flavor profile of your cookies.
Step 6: Combine wet and dry
Gradually add the dry ingredient mixture to the wet batter, mixing on low speed just until combined. Avoid overmixing to maintain a tender cookie texture. You’ll notice the dough becoming denser and richer—this is a good sign that your Peanut Butter M&M Chocolate Chip Cookies are coming together beautifully.
Step 7: Fold in chocolate and M&Ms
Carefully fold in 1 cup of mini chocolate chips and 1 cup of M&M candies using a rubber spatula. This adds a wonderful mix-in texture and color to your dough. Ensure that the candies and chocolate are evenly distributed throughout the dough, as each cookie should be a delightful surprise with every bite.
Step 8: Scoop and bake
Using a tablespoon, drop rounded balls of dough onto your prepared baking sheets, spacing them about 2 inches apart. Bake in the preheated oven for 10-12 minutes until the edges are lightly golden but the centers appear slightly underbaked. This will ensure chewy, soft interiors for your Peanut Butter M&M Chocolate Chip Cookies.
Step 9: Cool
Once baked, remove the cookies from the oven and let them cool on the baking sheets for about 5 minutes before transferring them to wire racks. This allows the cookies to set while still warm, achieving that perfect chewy texture. Allow them to cool completely before serving or storing in an airtight container.
Expert Tips for Peanut Butter M&M Chocolate Chip Cookies
- Don’t Overmix: When combining wet and dry ingredients, mix just until combined to ensure fluffy cookies. Overmixing can lead to toughness.
- Pay Attention to Baking Time: Keep a close eye on your cookies; they should look slightly underbaked in the center to achieve that soft, chewy texture.
- Chill the Dough: If your kitchen is warm, chilling the dough for 15 minutes can help maintain the cookie shape during baking.
- Storage Secrets: Store in an airtight container for up to 5 days, or freeze layers between parchment paper for longer freshness of your Peanut Butter M&M Chocolate Chip Cookies.
- Use Room Temperature Ingredients: Ensure your egg and butter are at room temperature for best integration, providing a smoother batter that leads to delicious results.
Make Ahead Options
These Peanut Butter M&M Chocolate Chip Cookies are perfect for meal prep, allowing you to enjoy fresh-baked goodness anytime! You can prepare the cookie dough up to 24 hours in advance—simply scoop dough balls onto a parchment-lined baking sheet, cover tightly, and refrigerate.

Peanut Butter M&M Chocolate Chip Cookies Recipe FAQs
What is the best way to select ripe ingredients?
Absolutely! For the best cookies, always choose the freshest ingredients. Look for smooth peanut butter without oil separation for a creamy consistency. Ensure your butter is soft enough to cream easily—leave it at room temperature for about 30 minutes before starting. Also, check your eggs for freshness by placing them in water: if they sink, they’re good; if they float, it’s best to discard them.
How should I store Peanut Butter M&M Chocolate Chip Cookies?
For optimal freshness, store your cookies in an airtight container at room temperature for up to 5 days. To keep them soft, include a slice of bread in the container—this simple trick keeps moisture levels just right! Alternatively, you can refrigerate them for up to a week, just make sure they’re well-sealed to avoid drying out.
Can I freeze Peanut Butter M&M Chocolate Chip Cookies?
Yes, you can absolutely freeze them! To do this, first, place your cookies in a single layer on a baking sheet and flash freeze until solid (about an hour). Next, transfer them to a zip-top bag or an airtight container, layering parchment paper between cookies to prevent sticking. They’ll stay delicious for up to 3 months. When you’re ready to enjoy, simply reheat them in a preheated oven at 350°F (175°C) for about 5-7 minutes until warm and gooey!
What if my cookies spread too much while baking?
Very often, the main reason cookies spread too much is due to the dough being too warm before baking. If this happens, try chilling the dough for about 15 minutes prior to scooping and baking. Also, ensure your butter is softened but not melted; melted butter will lead to overly runny dough. Additionally, check your oven’s temperature with an oven thermometer; if it’s too hot, that could cause excess spreading.
Are these cookies safe for pets or individuals with allergies?
If you’re considering sharing these delicious cookies with your furry friends, it’s important to remember that peanut butter can sometimes be harmful to dogs, especially if it contains xylitol—a sugar substitute. Always check the ingredient labels! For those with allergy concerns, feel free to replace peanut butter with almond butter or sunflower seed butter; just confirm the allergen status of any other ingredients used, especially the chocolates and candies.
Can I adjust this recipe for different dietary needs?
The more the merrier! For a gluten-free version, you can substitute all-purpose flour with a 1:1 gluten-free baking blend. If you want to reduce sugar, try using coconut sugar instead of brown and granulated sugars, or opt for natural sweeteners like honey or maple syrup. Additionally, you can make the cookies vegan by replacing the egg with a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons of water) and using a plant-based butter alternative.
