Halloween Whoopie Pies sandwich orange buttercream between soft chocolate cakes. Optional sprinkles around the filling give the edges extra color and crunch.
Ingredients and equipment
These are soft cake-like rounds rather than crisp cookies. Buttermilk is part of the batter; mix it alternately with the dry ingredients just until smooth.

Method and doneness
Drop rounded tablespoons of batter with space between them. Bake at 350°F for 10–12 minutes until set, then cool completely before pairing similarly sized rounds.
Beat the filling butter smooth before adding powdered sugar, vanilla, milk or cream and orange coloring. The filling should hold its shape when sandwiched.

Serving, storage and timing
Press the top halves on gently and roll the exposed filling in sprinkles if using. Store covered in the refrigerator and bring out portions for serving. Cooling time is additional to preparation and baking.
Keep refrigerated at 40°F or below. For serving, limit time out of refrigeration to 2 hours, or 1 hour above 90°F.
