Ingredients
Here’s what you will need to create these delightful Peanut Butter Marshmallow Cookies:
- 1/2 cup unsalted butter, softened – Always use high-quality butter for the best flavor. Brands like Kerrygold offer a rich, creamy taste.
- 2/3 cup creamy peanut butter – Natural peanut butter works wonders, but any creamy variety will do. Jif or Skippy are solid contenders.
- 1/2 cup granulated sugar – Regular white sugar for sweetness and texture.
- 1/2 cup light brown sugar, packed – This adds moisture and depth of flavor; use a good-quality brand.
- 1 large egg, room temperature – Eggs must be at room temp to ensure even mixing.
- 1 teaspoon vanilla extract – Use pure vanilla for an authentic flavor.
- 1 cup all-purpose flour – Standard flour works perfectly here.
- 1 teaspoon baking soda – A must for that chewy texture.
- 1/2 teaspoon kosher salt – Enhances the flavors.
- 1 cup mini marshmallows – The star of the show! They add wonderful chewiness.
- 1/2 cup semi-sweet chocolate chips – Go for brands like Ghirardelli or Nestle for top-quality chocolate.
- 1/2 cup peanut butter chips – These add an extra layer of peanut butter goodness!
Prep Notes: Make sure your butter is softened to room temperature for easy creaming.
Step-by-Step Instructions
-
Cream the Butter & Sugars: In the bowl of a stand mixer fitted with the paddle attachment (or using a hand mixer), cream together the softened butter, creamy peanut butter, granulated sugar, and brown sugar on medium speed until the mixture is smooth and fluffy—about 2-3 minutes.
-
Incorporate Egg & Vanilla: Add in the egg and vanilla extract, mixing until fully incorporated—this should take around 30 seconds.
-
Whisk Dry Ingredients: In a separate medium bowl, whisk together the all-purpose flour, baking soda, and kosher salt until combined.
-
Combine Wet & Dry: Slowly add the dry mixture to the peanut butter mixture, mixing on low speed just until everything is combined. Avoid overmixing—this helps keep your cookies tender.
-
Fold in Add-ins: Gently fold in the mini marshmallows, semi-sweet chocolate chips, and peanut butter chips using a spatula or wooden spoon until evenly distributed.
-
Chill the Dough: Cover the bowl with plastic wrap and refrigerate the dough for at least 1 hour, or until it’s firm. This step is crucial for controlling the spread of the cookies during baking.
-
Preheat the Oven: When you’re ready to bake, preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper for easy clean-up.
-
Scoop the Dough: Using a 2-tablespoon scoop, drop the cookie dough onto the prepared baking sheet, leaving about 2 inches between each one.
-
Bake: Place the cookies in the oven and bake for about 10 minutes, or until the edges are lightly golden and the centers look set but still soft. Don’t overbake; you want that gooey middle!
-
Cooling Time: Let the cookies cool on the baking sheet for about 1 minute before transferring them to a wire rack to cool completely.
Chef’s Tips:
- For extra chewiness, consider baking the cookies for slightly less time.
- Use a silicone baking mat for even better results!
Expert Tips & Tricks
-
Storage: Store your Peanut Butter Marshmallow Cookies in an airtight container at room temperature for up to a week. They can also be stored in the fridge for extended freshness.

Make-Ahead: The cookie dough can be made ahead of time and kept in the refrigerator for up to 3 days. You can also freeze the dough for up to 3 months—just thaw it in the fridge before baking.
-
Troubleshooting: If your cookies turn out flat, ensure your butter isn’t too warm or overly softened. Ideally, it should be cool to the touch.
-
Variations: Feel free to substitute almond butter or sunbutter for a different flavor profile, or mix in nuts for extra crunch.
-
Mixing Methods: Don’t be afraid to mix by hand if you don’t have a stand mixer. Just ensure you thoroughly combine all ingredients without the need for extreme force.
-
Taste Testing: Always save a few mini marshmallows or chocolate chips to sprinkle atop the cookies right before baking for that extra touch of goodness!
