  • Preparation Time:


I made these for work as part of an Instagram campaign. I looked for grapefruit cupcake recipes and couldn't find anything, so I modified a lemon cupcake recipe and the results were good.


  • 1/2 cup unsalted butter, softened to room temperature
  • 1 cup sugar
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 1 and 1/2 cups all-purpose flour
  • 2 teaspoons baking powder
  • 1/2 teaspoon salt
  • 1/2 cup milk
  • 2 to 3 tsp grapefruit zest
  • 6 tbsp fresh grapefruit juice


  • Preheat the oven to 350F.
  • Line 12-count muffin pan with paper liners or prepare the muffin pan with butter.
  • Beat the butter and sugar together on medium speed in a stand mixer for 2-3 minutes or until fluffy.
  • Add eggs and vanilla and beat on medium speed until everything is combined.
  • In a separate bowl, combine flour, baking powder, and salt.
  • Add the dry ingredients to the wet ingredients in 3 batches, stirring after each addition.
  • Add the milk, grapefruit zest, and grapefruit juice and mix until combined (don't overmix)
  • Pour batter evenly into 15 cupcake liners.
  • Bake for about 20 minutes. Check at 18 minutes, then again at 20.
  • Remove from the oven and allow to cool completely before frosting.
