This Key lime pound cake was inspired from a basic pound cake recipe that I like to play around with. It's now the only cake requested at every gathering. The unfrosted cake freezes well. —Pat Stewart, Canton, Georgia


  • 2 cups butter, softened
  • 2-1/2 cups sugar
  • 2 tablespoons grated key lime zest
  • 6 large eggs, room temperature
  • 2 tablespoons Key lime juice
  • 1 tablespoon vanilla extract
  • 4 cups (540 grams) cake flour
  • 1 teaspoon salt
  • 3/4 cup 2% milk
  • 1 package (8 ounces) cream cheese, softened
  • 1/2 cup butter, softened
  • 1 teaspoon grated key lime zest
  • 1 tablespoon Key lime juice
  • 3-3/4 cups confectioners' sugar
  • Lime slices, optional


  1. Preheat oven to 350°. Grease and flour a 10-in. fluted tube pan. In a large bowl, cream butter, sugar and zest until light and fluffy, 5-7 minutes. Add juice and vanilla, and mix on high for 1 minute. Add eggs, 1 at a time, on low speed just until yellow disappears. Scrape down bowl as needed and between each addition. Sift flour and salt together into clean bowl. Add 1/3 of the flour mixture alternately with 1/2 of the milk, on low speed until just mixed, beginning and ending with flour. Transfer to prepared pan.
  2. Bake until a toothpick inserted in center comes out clean or with a moist crumb, 1-1/4 to 1-1/2 hours. Cool in pan 10 minutes before removing to a wire rack to cool completely.
  3. For frosting, in a large bowl, beat cream cheese, butter, lime zest and lime juice until smooth. Gradually beat in confectioners' sugar. Spread over cake. If desired, garnish with lime slices and additional zest.

  • To remove cakes easily, use solid shortening to grease plain and fluted tube pans.
