Guinness Cupcakes:

Salted Caramel Buttercream:



  • For the cupcakes, preheat oven to 350F and line a muffin tray with 6 paper liners.
  • Use a handheld electric mixer to beat together the butter and sugar in a medium bowl. Once combined, beat in the egg and mix until light and fluffy. Beat in the Guinness, vanilla extract, and vanilla bean paste.
  • Whisk the flour, baking powder, and salt together in a small bowl. Add the dry ingredients to the wet and mix only until combined, scraping down the sides of the bowl as necessary, and being careful not to over-mix.
  • Pour the batter into the prepared tray and bake until a toothpick inserted inside comes out clean, about 18 to 20 minutes. Cool completely before frosting.
  • Once the cupcakes are cool, make the buttercream. Use a handheld electric beater to mix the butter, dissolved coffee, and caramel extract together in a medium bowl. Add the powdered sugar and continue beating while gradually adding milk until the buttercream is smooth and creamy. (You may need a little more milk or powdered sugar to achieve the right consistency.)
  • Frost the cupcakes with the buttercream and decorate with chocolate sprinkles if desired.


  • 1 cupcake is 1 serving.
  • You can easily double this recipe to make 1 dozen cupcakes.
