I made these light, tangy cupcakes on a chilly day to remind me of our vacation in southern Florida, where Key lime pies are star attractions. —Jennifer Gilbert, Brighton, Michigan


  • 1/2 cup butter, softened
  • 3/4 cup sugar
  • 1/4 cup packed brown sugar
  • 2 large eggs, room temperature
  • 1/2 teaspoon vanilla extract
  • 2 cups graham cracker crumbs
  • 3/4 cup all-purpose flour
  • 3 teaspoons baking powder
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1 cup 2% milk
  • 1 package (8 ounces) cream cheese, softened
  • 1/4 cup butter, softened
  • 2 teaspoons grated Key lime zest
  • 2 teaspoons Key lime juice
  • 1 teaspoon vanilla extract
  • 3-3/4 cups confectioners' sugar


  1. Preheat oven to 350°. Line 16 muffin cups with paper or foil liners.
  2. In a large bowl, cream butter and sugars until light and fluffy, 5-7 minutes. Add eggs, 1 at a time, beating well after each addition. Beat in vanilla. In another bowl, whisk cracker crumbs, flour, baking powder, cinnamon and nutmeg; add to creamed mixture alternately with milk, beating well after each addition.
  3. Fill prepared cups two-thirds full. Bake 15-20 minutes or until a toothpick inserted in center comes out clean. Cool in pans 10 minutes before removing to wire racks to cool completely.
  4. For frosting, in a large bowl, beat cream cheese, butter and lime zest until blended. Beat in lime juice and vanilla. Gradually beat in confectioners' sugar until smooth. Pipe or spread onto cupcakes. Refrigerate until serving.
Health Tip: Make just half of the frosting for a dollop of rich Key lime flavor on each cupcake and save 90 calories and 4 g fat.
