Chocolate Whoopie Pies

• For the pies
• 2 cups flour
• 1 cup sugar
• 1/3 cup cocoa
• 1 teaspoon baking soda
• 1/4 teaspoon salt
• 1 egg
• 1/3 cup salad oil
• 1 teaspoon vanilla
• 3/4 cup milk
• Filling
• 1/2 cup butter (1 stick) or 1/2 cup margarine (1 stick)
• 1 cup confectioners' sugar
• 1 cup marshmallow cream
• 1 teaspoon vanilla
• 1/8 teaspoon salt

1. Heat oven to 350 degrees. Mix together flour, sugar, cocoa, baking soda and salt in a mixer bowl. Add egg, oil and vanilla; slowly beat in milk until combined, about 2 minutes.
2. Drop batter by tablespoons onto parchment-lined baking sheets, leaving room between each for spreading. Bake 12 minutes. Cool completely on wire racks.
3. For filling, combine all ingredients in a bowl; beat until smooth. Spread about 2 tablespoons of the filling per cookie on the flat side of half of the cookies. Top with remaining cookies to make sandwiches.
