Peppermint Whoopie Pies

Wesley's Christmas program in on Monday and I'm super excited! My little tiny spawn is going to be up on a stage belting out Christmas songs along with a bunch of three year olds. How freakin cute will that be? Our assignment as parents is to bring cookies that will be devoured after the program. I want to bring something awesome. Something not ordinary, something mouthwatering. I've been looking through my cooking magazines and online recipes and think I've found a winner. They look labor intensive but I think it'll be worth it. Plus, how bad could they be coming from a website called butterisbest.com Mmmmm.....
I'll let you know how they turn out.

Ingredients:

Cookies:
2 cups flour
1/2 cup cocoa powder
1 teaspoon baking powder
1 teaspoon baking soda
1 teaspoon salt
1/2 cup (1 stick) butter
1 cup brown sugar, packed
1 egg
1 teaspoon pure vanilla extract
1/2 teaspoon peppermint extract
1 cup buttermilk

Filling:
1/2 cup (1 stick) butter, softened
1 7.5-ounce jar marshmallow fluff
2 teaspoons pure vanilla extract
1 1/4 cups powdered sugar
1 cup crushed peppermint candies (about 50 peppermint discs)

Cooking Directions:

Preheat oven to 350°F. In medium bowl, combine flour, cocoa powder, baking powder, baking soda and salt; set aside.

In large bowl, cream butter and brown sugar with electric mixer until light and fluffy. Add egg and extracts; mix well. Slowly add flour mixture and buttermilk, alternating, beginning and ending with flour mixture. Cover dough and chill at least 30 minutes.

Drop dough by rounded tablespoons onto parchment-lined baking sheet, placing cookies 2 inches apart. Bake cookies 9 to 12 minutes, or until firm. Cool cookies on pan 3 to 5 minutes or until set, then transfer to wire rack to cool completely.

For filling, in large bowl, cream together butter, fluff, and vanilla extract until light and fluffy. Add powdered sugar slowly; mix well. Spread flat side of half the cookies with heaping tablespoon of filling; top with second cookie to create sandwich. Roll edges in crushed peppermint candies; chill cookies to set filling.

Store unfilled cookies and filling in airtight containers in refrigerator for up to 1 week, and filled cookies for up to 3 days. Bring cookies to room temperature before serving.
