DIRECTIONS
In a large bowl, combine the cake mix, eggs, butter, water and lime juice; beat on low speed for 30 seconds. Beat on medium for 2 minutes.
Pour into two greased and floured 9-in. round baking pans. Bake at 375° for 20-25 minutes or until a toothpick inserted near the center comes out clean. Cool for 10 minutes before removing from pans to wire racks.
In a large bowl, combine milk and lime juice. Fold in whipped cream. Cut each cake horizontally into two layers. Place bottom layer on a serving plate; top with 1-1/4 cups filling. Repeat layers twice. Top with the remaining cake layer. Frost the top of cake with remaining filling.
Refrigerate for at least 1 hour. Serve with lime slices if desired. Yield: 10-14 servings. *Editor's Note:This recipe was tested with Duncan Hines Butter Recipe Golden Cake mix.
