Serves: 6


  • 1 cups soy milk
  • 2 Tbsp. Key lime juice, divided
  • 1 1⁄4 cups unbleached all-purpose flour
  • 1 cup sugar
  • 1⁄2 tsp. baking powder
  • 1⁄2 tsp. baking soda
  • 1⁄2 tsp. salt
  • 1⁄3 cup canola oil
  • 3⁄4 tsp. vanilla extract, divided
  • 1 Tbsp. Key lime zest, chopped, divided
  • 4 oz. vegan cream cheese, softened
  • 1⁄4 cup vegan margarine, softened
  • 1 cups confectioners' sugar


  • Preheat oven to 350°F.
  • Combine soy milk and 1 1⁄2 tablespoons lime juice in a medium bowl. Allow to sit for 10 minutes to thicken. In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt. Set aside. Add oil, 1⁄2 teaspoon vanilla extract, and 2 teaspoons lime zest to the soy milk mixture, whisking to combine.
  • Add wet ingredients to the flour mixture, stirring gently until there are no large lumps. Pour into a greased and floured 8-inch round cake pan.
  • Bake for 35 to 40 minutes or until a toothpick comes out clean when inserted into the center of the cake.
  • To make icing, beat cream cheese and margarine on medium speed until blended. Beat in confectioners' sugar. Then add remaining 1⁄2 tablespoon lime juice, remaining 1⁄2 teaspoon zest, and remaining 1⁄8 teaspoon vanilla extract. Beat 1 to 2 minutes until smooth and creamy.
  • Cool 10 to 15 minutes in the pans. Run a knife around the edges of the cakes and remove from the pans. Cool completely. Place one cake on a serving platter and frost with icing.
