Ingredients
- 1 3/4 cups + 2 Tbsp all-purpose flour
- 1 cup quick oats, slightly ground in a food processor
- 2 tsp cocoa powder
- 1 1/2 tsp cornstarch
- 1 tsp baking powder
- 1/2 tsp baking soda
- 3/4 tsp salt
- 3/4 tsp cinnamon
- 1/4 tsp ground nutmeg
- 1/4 tsp ground ginger
- 1/2 cup butter, softenend
- 1/2 cup shortening, unflavored
- 1 1/4 cups granulated sugar
- 2 1/2 Tbsp molasses
- 2 large eggs
- 1 tsp vanilla extract
- 1/8 tsp coconut extract
- Red and yellow gel food coloring, optional
- 1/2 cup butter, nearly at room temperature
- 1/4 cup shortening, unflavored
- 1 1/2 cups powdered sugar
- 7 oz. marshmallow creme
Directions
- Heat the oven to 350 degrees. In a mixing bowl, whisk the flour, oats, cocoa powder, cornstarch, baking powder, baking soda, salt, cinnamon, nutmeg and ginger until evenly combined, then set the bowl aside.
- In the bowl of an electric stand mixer fitted with the paddle attachment, beat the butter, shortening, sugar and molasses on medium-high speed until the mixture looks light and fluffy, about 2 minutes. Add the eggs, mixing well after each one goes in. Beat in the vanilla and coconut extract.
- Add the dry mixture gradually, mixing just until everything comes together. If you want to use food coloring, stir in a small amount, using more yellow than red if using both, since a little is plenty here.
- Portion the dough into about 2 Tbsp amounts and roll them into balls, or simply drop the dough onto the cookie sheet without shaping. Arrange them on a Silpat-lined baking sheet, placing 9 on each sheet.
- Bake at 350 degrees for 10 – 12 minutes. The cookies should still feel soft and not completely firm, so don’t let them go too far. Leave them on the baking sheet for several minutes, then move them to a wire rack and let them cool completely.
- For the marshmallow buttercream filling, beat the butter and shortening in the bowl of an electric stand mixer fitted with the paddle attachment on medium-high speed until pale and fluffy, about 3 – 4 minutes. Add the powdered sugar and mix on low until incorporated, then turn the mixer to medium-high and beat for 1 minutes. Mix in the marshmallow creme.
- Spread the marshmallow buttercream filling over the flat side of one cooled cookie, then top it with the flat side of another cookie to make a sandwich. Store the finished cookies in an airtight container at room temperature.
