Key Lime Cupcakes Recipe

Yield: 36 cupcakes


3 cups all-purpose flour
2 teaspoons baking powder
1 teaspoon salt
2 cups granulated sugar
1 cup butter, softened
4 large eggs
1 tablespoon key lime zest
1 teaspoon vanilla extract
2 cups buttermilk

Key Lime Filling:
1 (8 oz) package cream cheese, softened
1/2 cup sweetened condensed milk
4 oz key lime juice

Key Lime Buttercream:
1 cup butter, softened
6–8 cups powdered sugar
1/2 cup Key Lime Filling
1/4 cup key lime juice
1/4 teaspoon salt

Graham Cracker Crumble:
2 graham cracker rectangles, crumbled
2 tablespoons butter, melted
1 tablespoon light brown sugar


To make the cupcakes:

  1. Preheat the oven to 350ºF. Line 36 muffin tins with cupcake liners.
  2. In a bowl, combine the flour, baking powder and salt. Set aside.
  3. In a large bowl, or the bowl of a stand mixer, beat the sugar and the butter together on medium speed until combine. Add in the eggs, one at a time, scraping down the sides of the bowl as needed. Add the the zest and the vanilla and beat to combine.
  4. With the mixer on low speed, add 1/3 of the flour mixture. When it’s almost mixed in, add half of the buttermilk, followed by an additional 1/3 of the flour, and then the final buttermilk. Continue to beat just until it is blended.
  5. Divide the batter evenly between the prepared muffin tins, filling each about 2/3 full.
  6. Bake until a tester inserted in the middle of the cupcakes comes back with just a few crumbs, about 15 to 18 minutes. Cool in the pans for 5 minutes before removing to a cooling rack to cool completely.
