Chocolate Eggnog Cupcakes with Rum-Infused Frosting

For the cupcakes:
• 1 1/4 cups sifted all-purpose flour
• 1/2 tsp. baking soda
• 1/4 tsp. salt
• 8 tbsp. unsalted butter
• 1 1/4 cups sugar
• 2 large eggs
• 1 1/4 tsp. pure vanilla extract
• 1 cup eggnog
• 1/2 cup dark rum
• 1/2 cup sifted cocoa powder

For the rum-infused frosting:
• 4 tbsp. unsalted butter
• 4 cups sifted confectioners' sugar
• 1/4 tsp. pure vanilla extract
• 6 oz. cream cheese
• 1/4 cup dark rum
• 2 tbsp. freshly ground nutmeg

For the cupcakes:
Preheat the oven to 350šF. Line a cupcake pan with 12 paper baking cups, and a second pan with six baking cups. Sift together the flour, baking soda, and salt in a bowl, and set aside.

In the bowl of a stand mixer or in a bowl with a handheld electric mixer, creamtogether the butter and sugar on medium speed until light and fluffy, approximately 3 to 5 minutes. Add the eggs one at a time, mixing slowly after each addition. Combine the vanilla and eggnog in a large liquid measuring cup.

Add one third of the flour mixture to the butter mixture, then gradually add one third of the eggnog mixture, beating slowly until well incorporated. Add another third of the flour mixture, followed by another third of the eggnog mixture. Stop to scrape down the bowl as needed. Add the remaining flour mixture, followed by the remaining eggnog mixture, and beat just until combined.

Add the rum, and mix until just combined. Add the cocoa powder, beating on low speed just until incorporated. Using a standard-size ice cream scoop, fill each baking cup so that it is two-thirds full. Bake for 18 to 20 minutes (start checking at 15 minutes) or until a toothpick inserted into the center of a cupcake comes out clean. Transfer the pans to a wire rack to cool completely.

For the frosting:
In the bowl of a stand mixer or in a bowl with a handheld electric mixer, mix all the ingredients, except for the nutmeg, for approximately 3 to 5 minutes, until the frosting is light and airy. Using a large round metal piping tip, frost each cupcake with a nice swirl and then top with a dusting of freshly ground nutmeg.
