  7. 2 teaspoons grated Key lime or regular lime peel
  8. 3 eggs

  1. 1 Heat oven to 350°F. Grease bottoms only of two 8- or 9-inch round cake pans (dark or nonstick pans not recommended). Line pans with waxed paper. Grease waxed papers and sides of pans; lightly flour. In medium bowl, mix cracker crumbs, sugar and melted butter. Spread 2/3 cup of mixture in each pan.
  2. 2In large bowl, beat cake mix, lime juice mixture, softened butter, 2 teaspoons lime peel and eggs with electric mixer on low speed 30 seconds, then on medium speed 2 minutes, scraping bowl occasionally. Pour into pans.
  3. 3Bake 8-inch rounds 36 to 43 minutes, 9-inch rounds 32 to 38 minutes, or until toothpick inserted in center comes out clean. Run sharp knife around sides of pans to loosen cakes. Cool in pans 15 minutes. Remove from pans to cooling rack, placing cakes crumb-mixture-side-up and removing waxed paper from tops of cakes. Cool completely, about 1 hour.
  4. 4To make Creamy Key Lime Filling and Frosting, in small bowl, stir together condensed milk, 2 teaspoons lime peel and 1/2 cup lime juice; set aside. Beat whipping cream in chilled medium bowl with electric mixer on high speed until soft peaks form. Fold milk mixture into whipped cream just until blended.
