Description
Delightful cookies filled with gooey marshmallow fluff, chocolate, and M&Ms for the ultimate sweet treat.
Ingredients
Scale
- 1 cup unsalted butter, room temperature
- 1 cup creamy peanut butter
- 1 ½ cups light brown sugar, packed
- 2 large eggs, room temperature
- 2 cups all-purpose flour
- 1 cup old-fashioned oats
- 1 teaspoon baking soda
- ½ teaspoon kosher salt
- 1 ½ cups plain M&M candies
- 1 ½ cups semi-sweet chocolate chips
- 1 jar (7 ounces) marshmallow fluff
- Mini M&M candies, for topping (optional)
Instructions
- Preheat the oven to 350°F (175°C) and line baking sheets with parchment paper.
- Beat the unsalted butter on medium-high speed until smooth. Add the creamy peanut butter and mix for an additional 2 minutes until well combined.
- Add in the packed brown sugar and mix until smooth (about 2 minutes). The mixture should be light and fluffy.
- Add the eggs one at a time, mixing for 30 seconds after each addition. Remember to scrape the sides of the bowl to combine everything.
- With the mixer off, add flour, oats, baking soda, and salt; mix on low until just combined—it should look slightly crumbly.
- Add the M&M candies and semi-sweet chocolate chips, mixing until incorporated.
- Using a 2-tablespoon cookie scoop, drop dough onto the prepared sheets and flatten each disk slightly.
- Spoon marshmallow fluff into the center of half the disks, cover with another disk, and seal the edges firmly to keep the marshmallow hidden.
- If desired, top with mini M&Ms for an adorable finish!
- Bake for 15-16 minutes until the edges are golden brown.
- Let cookies cool on baking sheets for about 5 minutes before transferring them to a wire rack.
Notes
Store in an airtight container for up to 5 days or freeze for longer storage. Be careful not to overmix the dough after adding flour.
