Homemade Cupcake Recipe

  • 1 ½ cups cake flour*
  • 2 teaspoon baking powder
  • ½ teaspoon salt
  • ½ cup butter
  • ½ cup white sugar
  • ½ cup brown sugar
  • 2 eggs
  • 1 teaspoon vanilla
  • ½ cup buttermilk
  • 2 tbs grapefruit zest
  • 3 tbs grapefruit juice

Grapefruit Cream Cheese Frosting Recipe

  • ½ cup unsalted butter softened
  • 8 oz cream cheese softened
  • 4-5 cups powdered sugar
  • 3-4 tbs grapefruit juice
  • 2 tbs grapefruit zest
  • Food coloring optional


How to make grapefruit cupcakes:

  • Preheat oven to 350°F. Line a cupcake pan with cupcake liners.
  • Combine flour, baking powder and salt in a medium bowl, set aside.
  • Cream butter and sugar. Then add eggs and vanilla, making sure they are fully incorporated.
  • Mix flour mixture into butter mixture until just combined.
  • Add in buttermilk, grapefruit juice, and grapefruit zest. Mix until fully combined.
  • Divide batter into 12 cupcakes.
  • Bake for 18-20 minutes or until a toothpick inserted comes out clean.
  • Let the cupcakes cool completely before frosting.

How to make grapefruit cream cheese frosting:

  • With a hand mixer or a stand mixer, cream butter and cream cheese on medium high until fully combined.
  • Add in powdered sugar 1 cup at a time, adding in grapefruit juice in intervals to help the powdered sugar incorporate. The more powdered sugar the stiffer the frosting. I like to use at least 4 cups.*
  • Stir in the zest, and food coloring if using, and frost your cupcakes!
  • Enjoy!


*You can use all-purpose flour if you need to. *Refrigerating the frosting will also help it to thicken and will pipe on nicely to the cupcakes.
