GREAT recipe with a layer of chocolate and marshmallow smashed between two peanut butter cookies! It was the winner in Parenting's holiday cookie contest, and I had to post it for my cookbook here!

• Ready In: 1 hr
• Serves: 12
• Yields: 12-24 cookies

Ingredients

•  cooking spray

• Peanut butter cookie

• 2⁄3 cup all-purpose flour
• 1  teaspoon baking soda
• 1⁄2 cup unsalted butter, softened
• 1  cup creamy peanut butter
• 1 1⁄3 cups  packed light brown sugar
• 1  large egg, beaten
• 3⁄4 teaspoon vanilla extract

• Filling

• 1⁄2 cup  milk chocolate chips
• 2  tablespoons unsalted butter
• 1⁄2 cup marshmallow cream

Directions

1. Preheat oven to 375°F Lightly coat a cookie sheet with cooking spray. Mix flour and baking soda in a small bowl; set aside.
2. With a spoon, mix butter, peanut butter, and brown sugar in a medium bowl until smooth. Add egg and vanilla, and beat until smooth. Add flour mixture, and stir until combined.
3. Roll dough into 1-inch balls and flatten with a fork; bake 8 to 10 minutes. Remove from oven and let stand for 10 minutes, then place cookies in the refrigerator for 20 minutes.
4. While cookies cool, place chocolate chips and butter in a microwave-safe bowl; heat about 1 minute, until just melted. Let stand for 30 minutes, or until slightly stiff.
5. Heat marshmallow cream in microwave for 10 seconds to soften. Spread marshmallow on a cookie, chocolate on another and sandwich together. Store finished cookies in the fridge.
