Prep Time: 10 minutes
Cook Time: 12 minutes
Freeze Time: 1-2 hours
Total Time: 1 hour, 22 minutes
Yields: 20 cookies
INGREDIENTS
1 1/2 cups all-purpose flour (stir, spoon & level)
1 tsp baking soda
1/2 tsp salt
1/2 cup unsalted butter, softened
1/2 cup granulated sugar
1/2 cup light brown sugar, packed
1/2 cup creamy peanut butter
1 large egg
1 tsp vanilla extract
1 cup mini marshmallows, frozen* (freeze 1-2 hours before starting recipe)
INSTRUCTIONS
Preheat oven to 350°F. Line cookie sheets with a silicone baking mat or parchment paper and set aside.
In a medium bowl, stir together the flour, baking soda and salt; set aside.
Cream the butter and both sugars with an electric mixer until light and creamy.
Add the peanut butter, egg, and vanilla. Mix well and scrape bowl. Add the dry ingredients and mix until almost incorporated.
Remove marshmallows from freezer and fold a cup of marshmallows into the cookie dough.
Shape the cookie dough into balls (about 2 TBSP balls). Place a few inches apart on a prepared baking sheet. Place remaining cookie dough in the fridge to keep marshmallows cold until ready to bake.
Bake cookies at 350˚F for 11-12 minutes or until just set and edges are starting to brown. Allow cookies to cool completely on tray, about 10 minutes. After 2-3 minutes of cooling, use a greased spatula to round any misshapen cookies, if desired. Transfer cooled cookies directly to serving platter or airtight container. May stick to a wire cooling rack.
Enjoy! Best served immediately, or keep in airtight container at room temperature.
