Ingredients

  • 1 box lemon cake mix 16.5 oz Duncan Hines Lemon Supreme
  • 3 ounce package of lime flavored Jell-O
  • 2/3 cup vegetable oil original recipe called for 1 1/3 cup, but cake doesn't need it
  • 3/4 cup orange juice
  • 4 large eggs

Flavor Enhancing Glaze

  • 2 tablespoons fresh lime juice or bottled Key lime juice
  • 4-6 tablespoons powdered sugar

Frosting

  • 8 oz cream cheese softened
  • 1 cup powdered sugar
  • 1/2 scant cup granulated sugar
  • About 14-16 oz of non-dairy whipped topping**

Instructions

  • Preheat oven to 350 degrees F. Grease and flour three 8 inch round cake pans or spray thoroughly with flour-added baking spray. 9 inch pans may be used as well, but the cake will be shorter.
  • Mix the cake mix, Jell-O, oil, orange juice and eggs in a large bowl and beat well with an electric mixer for about 2 minutes. Pour into pans and bake for 20 to 23 minutes or until a toothpick inserted comes out clean. Let cool for about 10 minutes in the pans, then remove layers from pans. Mix together the lime juice and powdered sugar and spoon over the cake. Let it cool completely.
  • To make the frosting, mix together cream cheese and sugars and beat with an electric mixer until smooth. Fold in the whipped topping. You can use the full 16 oz or use less to taste. Spread the icing on top of the cakes, then stack and spread it all over the sides. If you feel like it, pipe icing around the edge and garnish with limes.

Notes

You can always swap out the whipped topping with lightly sweetened whipped cream.
