For the cupcakes: Preheat the oven to 350 degrees F. Line muffin tins
with cupcake liners.
In a stand mixer
with the paddle attachment, cream together the butter and sugar. In a separate bowl, whisk
together the buttermilk
, extract and eggs. In another bowl, sift
the flour, baking powder and baking soda. Add the orange liqueur and orange zest
Alternate the egg mixture and flour mixture into the butter and sugar until well combined. Make sure to scrape down the sides of the bowl and mix well. Spoon the mixture into the prepared muffin tins. Bake until a toothpick inserted into the center of the cupcakes comes out clean, about 35 minutes. Let cool completely before frosting. While the cupcakes are baking, make the frosting.
For the frosting: Beat the butter, honey, orange extract and salt until smooth. Then slowly add the powdered sugar, 1 cup at a time, the cocoa powder, heavy cream and orange liqueur
Refrigerate the frosting until the cupcakes are cooled, about 30 minutes. Frost each cupcake and serve.
