Ingredients
Scale
- 1 cup creamy peanut butter (unsweetened recommended)
- 1 cup granulated sugar
- 1 large egg (room temperature)
- 1 teaspoon vanilla extract
- 1/2 cup gluten-free all-purpose flour blend (with xanthan gum)
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 3/4 cup mini marshmallows (about 3–4 per cookie)
Instructions
- Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat.
- In a large bowl, combine peanut butter, sugar, egg, and vanilla extract. Beat until smooth and creamy, about 2 minutes.
- Sprinkle gluten-free flour blend, baking soda, and salt over the wet mixture. Mix until just combined; do not overwork.
- Use a medium cookie scoop (about 2 tablespoons per cookie) to portion dough onto the prepared baking sheet, spacing about 2 inches apart.
- Gently flatten each dough ball to about 1/2 inch thick. Top each with 3-4 mini marshmallows, pressing lightly so they stick.
- Bake for 10-12 minutes, until cookies are lightly golden around the edges and marshmallows are puffed and just starting to brown.
- Remove from oven and let cookies sit on the baking sheet for 5 minutes. Transfer to a cooling rack to finish setting.
- Serve warm for gooey marshmallows or let cool completely for a chewier texture.
Notes
For nut allergies, substitute peanut butter with sunflower seed butter. Chill dough for thicker cookies. Watch marshmallows closely in the last minutes of baking to avoid burning. Add chocolate chips or festive sprinkles for variation. Cookies freeze well for up to 2 months.
