Ingredient Notes for Peanut Butter M&M Cookies

Here's a quick rundown of the ingredients needed- see the recipe card below for full details.

• Unsalted Butter– Make sure it's softened to room temperature. This helps create fluffy, soft peanut butter cookies that spread just right.
• Creamy Peanut Butter– Classic brands like Jif or Skippy work best for this recipe. Avoid natural peanut butter-it can make the cookies too oily or dry.
• Instant Vanilla Pudding Mix– A secret weapon for ultra-soft and chewy cookies! Use a 3.4 oz box of instant pudding mix (not cook-and-serve).
• Light Brown Sugar– Adds moisture and chewiness, which is essential in a good peanut butter cookie.
• Granulated Sugar– Helps sweeten and balance the texture for these soft cookies.
• Large Eggs– Bind everything together and keep the cookies rich and tender.
• All-Purpose Flour– Provides the structure. For gluten-free peanut butter M&M cookies, you can use a 1:1 gluten-free flour substitute.
• Baking Soda/ Salt– Essential for rise and flavor.
• Mini Chocolate Chips– Add extra chocolatey goodness to each bite. You can use regular chips too, but minis mix in better with the candy.
• Peanut Butter M&M’s– The star of the show! These candy-coated treats add crunch and color. Don't forget to press a few extras on top of each cookie before baking for that bakery-style look.

How To Make Chewy Peanut Butter M&M Cookies

Tips for Success

Want soft, chewy peanut butter cookies that look as good as they taste? Here's how to make this easy peanut butter cookie recipe turn out perfect every time:

• Use room temperature butter and eggs - This helps everything mix smoothly and keeps your dough from becoming too dense.
• Don't overmix the dough - Stir just until the flour disappears to keep the cookies soft and tender.
• Measure flour carefully - Too much flour = dry cookies. Spoon it into your measuring cup and level it off for accuracy.
• Can't find peanut butter M&Ms? - Swap in mini M&Ms, regular M&Ms, or even Reese's Pieces for a fun twist.
• Use a cookie scoop - It keeps your cookies uniform in size so they bake evenly (plus, it makes things quicker and tidier). Depending on desired size cookies, use a medium or large cookie scoop.

Storing and Freezing Peanut Butter M&M Cookies

• Room Temperature: Store baked peanut butter M&M cookies in an airtight container at room temp for up to 5 days. Add a slice of bread to the container to keep cookies extra soft!
• Refrigerator: You can refrigerate them for up to 7 days, but keep in mind-they'll firm up a bit. Pop one in the microwave for 10-15 seconds to bring back that fresh-from-the-oven softness.
• Freezer (Baked Cookies): Let cookies cool completely, then place in a freezer-safe bag or container. Freeze for up to 3 months. Thaw at room temp or warm in the microwave when ready to enjoy.
• Make-Ahead Tip: Freeze the Dough! Want freshly baked cookies on demand? Freeze the dough instead! Bake straight from frozen-just add 1-2 extra minutes to the bake time. Scoop the cookie dough into balls and place on a lined baking sheet. Freeze until solid (about 1 hour), then transfer dough balls to a freezer-safe bag. Store for up to 3 months.
