There’s something utterly magical about a Peanut Butter Marshmallow Cookie that instantly takes me back to my childhood kitchen, where Mama Lou would bake with such love and laughter. The scent of peanut butter mingling with sweet marshmallows always meant we were in for a treat, a moment to pause and savor the simple joys of family and tradition. My sister Ouma and I would eagerly wait by the oven, watching those golden edges form, while Mama Lou told stories of her own childhood. Baking these cookies isn’t just about mixing ingredients; it’s about reliving those warm memories and creating new ones with every batch.
Why You’ll Love This Peanut Butter Marshmallow Cookie
This Peanut Butter Marshmallow Cookie is a perfect blend of nostalgia and pure comfort. It’s chewy, gooey, and packed with the rich, nutty flavor of peanut butter balanced by the soft sweetness of marshmallows.

The marshmallows add an unexpected melt-in-your-mouth texture that Ouma calls “little pockets of happiness.” Plus, these cookies come together quickly, making them perfect for last-minute cravings or cozy weekend baking sessions.

- Total Time: 45 minutes
- Yield: 4 servings 1x
Ingredients
- 1 cup creamy peanut butter (feel free to use natural or homemade peanut butter for a rustic touch)
- 3/4 cup granulated sugar
- 1/2 cup packed light brown sugar
- 1 large egg, at room temperature
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour (you can substitute with gluten-free flour if needed)
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1 cup mini marshmallows (fresh is best, but you can use slightly stale ones for easier melting)
Instructions
- Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper. I always use parchment to keep my cookies from sticking and to make clean-up a breeze—Mama Lou swore by it!
- In a large mixing bowl, cream together the peanut butter, granulated sugar, and brown sugar until the mixture is light and fluffy. This usually takes about 3-4 minutes with an electric mixer. I remember Ouma and I taking turns mixing while Mama Lou prepared the next step—it was our little dance in the kitchen.
- Beat in the egg and vanilla extract until fully incorporated. The mixture will look glossy and smooth, signaling it’s ready for the dry ingredients.
- In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add this to the peanut butter mixture, folding gently until just combined. Don’t overmix here; you want tender cookies, not tough ones.
- Carefully fold in the mini marshmallows, saving a few to press on top of each cookie before baking. This little step makes the cookies look extra inviting—Mama Lou called it the “sweet little kiss.”
- Using a tablespoon or small cookie scoop, drop dough balls onto the prepared baking sheets, spacing them about 2 inches apart. Gently press a couple of marshmallows on top of each cookie for that melty finish.
- Bake for 10-12 minutes, or until the edges are golden and the marshmallows are puffed and slightly toasted. The center will still look soft—that’s exactly how it should be!
- Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack. I always sneak a warm one during this time—Ouma says it’s the best way to enjoy them, straight from the oven.

Tips for Making the Best Peanut Butter Marshmallow Cookie
- Use room temperature ingredients. Eggs and peanut butter mix more evenly when not cold, giving you a smoother dough and better texture.
- Don’t skip the parchment paper. It keeps your cookies from sticking and helps them bake evenly, a trick I learned from Mama Lou after a few sticky mishaps.
- Be gentle folding in marshmallows. Too much stirring can cause them to melt prematurely, which changes the texture of your dough.
- Experiment with peanut butter types. Creamy offers a classic taste, while chunky adds delightful texture. Mama Lou always preferred chunky, saying it reminded her of Sunday afternoons with Ouma.
- Press marshmallows on top before baking. This ensures they toast beautifully and gives your cookies a bakery-style finish.
- Watch your baking time closely. The cookies continue to cook slightly on the hot pan, so pulling them out when edges are golden but centers soft is key for that chewy perfection.
Serving Suggestions and Pairings
These cookies are a treat on their own, but I love pairing them with a cold glass of milk or a warm cup of coffee, which brings out the nutty richness of peanut butter. Sometimes, on chilly afternoons, Ouma and I would share these cookies alongside hot cocoa topped with whipped cream, a tradition Mama Lou started. For a grown-up twist, a drizzle of dark chocolate or a sprinkle of sea salt elevates these cookies beautifully.
If you’re looking to turn these into a dessert plate, serve them with a scoop of vanilla ice cream or alongside fresh berries to balance the sweetness. They also make a heartwarming gift—wrapped in parchment and tied with twine, they carry a story of love, family, and simple joys.

Storage and Reheating Tips
Once cooled completely, store your Peanut Butter Marshmallow Cookies in an airtight container at room temperature. They stay fresh for up to 5 days, though they rarely last that long in my house! For longer storage, freeze them for up to 3 months, separating layers with parchment paper to prevent sticking.
To reheat, pop a cookie in the microwave for about 10-15 seconds to revive that gooey marshmallow softness. I love this little ritual—it’s like bringing a piece of Mama Lou’s kitchen warmth back to life on a busy day.
