Lime Buttercream Frosting

Tangy and sweet, this lime buttercream frosting is perfect for summer! Pair it with chocolate, vanilla, citrus or cinnamon cupcakes.


  • 1/2 cup unsalted butter softened to room temperature

  • 4 tbsp heavy cream
  • 1 tsp vanilla extract
  • green gel food coloring optional
  • 1/2 cup freshly squeezed lime juice


  • Juice two limes and set aside the juice.
  • Cream the butter and Crisco on high speed, until smooth. Mix in 3 3/4 cups of powdered sugar and 2 tablespoons of heavy cream on low speed, until combined. Mix in the remaining powdered sugar, the lime juice, 2 tablespoons of heavy cream, the vanilla and food coloring. Once incorporated, mix on high speed until creamy and fluffy.
