  • ½ tablespoon baking powder
  • ¼ teaspoon salt
  • ½ cup butter room temp

  • 2 eggs room temp
  • ¼ cup honey
  • ¼ cup spiced rum
  • 1 tablespoon vanilla extract
  • ½ cup almond milk

For the buttercream:

  • 2 sticks butter room temp
  • 2 ½ cups powdered sugar
  • 2 tablespoon rum

  • sprinkle of nutmeg

Instructions

For the cupcakes:

  • Preheat oven to 350ºF and prepare a cupcake tin with liners.
  • In a large bowl, mix dry ingredients and set aside.
  • In a standard mixer, cream butter and sugar until light and fluffy.
  • Add in eggs one at a time until fully mixed.
  • Add the vanilla, rum, and honey until combined.
  • Alternate adding your dry ingredients with the almond milk until fully combined and smooth.
  • Pour batter into your cupcake liners about ¾ of the way full and bake for about 20 minutes, or until a toothpick comes out clean.
  • Let cupcakes cool fully before frosting.

For the buttercream:

  • In a small saucepan, brown the butter over medium heat - simply let it melt and brown for about 3-4 minutes, stirring often until it smells nutty and looks dark brown in color. Let the browned butter cool to room temperature.
  • In a standard mixer, cream together 2 cups powdered sugar, 1 stick of butter, and your browned butter until smooth.
  • Add in your rum, vanilla, and nutmeg, then add another ½ cup of powdered sugar to finish off the buttercream.
  • Scoop buttercream into a piping bag with a star tip and frost your cupcakes.
  • Sprinkle some nutmeg and toasted pecans on top, then serve!
