  • 1 can (14 ounces) sweetened condensed milk
  • 2 teaspoons grated Key lime or regular lime peel
  • 1/2 cup Key lime or regular lime juice
  • 1 1/2 cups whipping (heavy) cream


  • 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.

    In 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.

    Bake 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.

Tips from the Betty Crocker Kitchens

  • tip 1
    Shave off some twists of lime peel to trim the top of this cake. In a hurry? Use small slices of lime as a garnish.
  • tip 2
    Key limes, grown in Florida, are a fraction of the size of the limes that are usually seen in the grocery store and are more yellow than green in color. Fresh Key limes are available in specialty produce markets or gourmet food stores, but fortunately, bottled unsweetened Key lime juice is widely available. Look for it next to the bottled lemon juice.
