Peanut Butter and Chocolate Sandwich Cookies
Ingredients
Instructions
- Heat the oven to 350°F (175°C). Melt the peanut butter chips and 3 tablespoons softened butter in a small saucepan over very low heat. Remove from heat and cool slightly.
- Beat the remaining 1/2 cup softened butter and 1 cup sugar in a large bowl until fluffy. Add the corn syrup, egg, and vanilla; blend thoroughly. Stir together 2 cups flour, the baking soda, and salt; add to the butter mixture and blend well.
- Remove 1 1/4 cups of the dough to a small bowl. Stir the remaining 2 tablespoons flour and the melted peanut butter chip mixture into this portion.
- To the remaining dough, add the cocoa, remaining 1/4 cup sugar, and 5 tablespoons melted butter; blend. Refrigerate both doughs for 5 to 10 minutes, or until firm enough to handle.
- Roll each dough into 1-inch balls and roll in additional sugar. Place on ungreased cookie sheets. Bake for 10 to 11 minutes, or until set. Cool slightly, transfer to wire racks, and cool completely.
- Place one marshmallow, flat side down, on each chocolate cookie. Microwave at MEDIUM (50%) for about 10 seconds, or until softened. Top with a peanut butter cookie, pressing down slightly. Repeat with the remaining cookies and serve immediately.
Storage
Store fully cooled cookies in an airtight container at room temperature for up to 5 days. Freeze for up to 2 months, unless the marshmallow sandwich cookies are being served warm.
