Baking Time




  • 10 Tbsp (5 oz) butter at room temperature
  • 5 Cups (22 oz) 10x powdered sugar
  • 2 ½ Tbsp milk
  • 1 1/2 tsp vanilla – clear
  • pinch salt
  • 2/3 Cup (5 oz) high ratio shortening
  • 1 Tbsp Tequila
  • 1 Tbsp Triple Sec
  • 1 Tbsp Lime Juice
  • Zest of 1 lime


Mix the butter, sugar, milk, vanilla and salt using the paddle attachment of a Kitchen Aid style mixer or a hand mixer for 5 minutes at low speed and then 2 minutes at medium speed. Add the shortening and mix for 2 minutes at medium speed. Add the tequila, triple sec, lime juice and lime zest and continue mixing for another 5 minutes at low speed until light, fluffy and smooth.

This is a delicious variation to our standard American Buttercream. Adding the butter makes it less temperature stable and not as stiff for piping, but the flavor is delicious. Still be sure to use the high ratio shortening instead of a regular shortening, so it has a creamy consistency and is nice and fluffy. This recipe is enough icing for approximately 24 cupcakes.
