Ingredients
1 cup unsalted butter, softened
1 cup brown sugar
1/2 cup white sugar
1 large egg
2 teaspoons vanilla extract
1 1/2 cups all-purpose flour
1/2 teaspoon baking soda
1/2 teaspoon salt
2 cups old-fashioned oats
1 1/2 cups mini marshmallows
Instructions
1. Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper or a silicone baking mat.
2. In a large bowl, cream the butter, brown sugar, and white sugar until light and fluffy.
3. Add the egg and vanilla extract, and mix until fully combined.
4. In a separate bowl, whisk together flour, baking soda, and salt. Gradually add to the wet mixture.
5. Stir in the oats until well incorporated.
6. Scoop about 1.5 tablespoons of dough, flatten slightly, place 2-3 mini marshmallows in the center, then wrap and seal the dough around them into a ball.
7. Place on the prepared baking sheet and bake for 10-12 minutes or until edges are golden and centers look slightly underdone.
8. Allow cookies to cool on the baking sheet for 5-10 minutes before transferring.
Notes
Make sure to fully seal the dough around the marshmallows to prevent leaking.
Chill the dough for 30 minutes before baking for a thicker cookie.
Serve slightly warm for the best gooey marshmallow texture.
