Add 2 eggs, 1/3 cup vegetable oil, 1 1/2 teaspoons raspberry extract, and 1/2 cup peach liquid to cake mix. Bake 2 (8-inch) cakes according to package directions.
Let cakes cool completely. Transfer cakes to inverted 9-inch pie tins to function as a cake stand.
Add remaining 1/2 teaspoon raspberry extract to 1 can of frosting. Stir thoroughly. Frost both cakes.
Divide remaining can of frosting between 2 mixing bowls. Add 3 tablespoons confectioners' sugar to both. Add 7 drops of food coloring to each - red in 1, green in the other. Mix thoroughly and transfer to 2 plastic bags. Snip small corner off bags and use to pipe a decorative border around the base of the cakes - 1 green, 1 pink. Decorate cake with green vines and pink flowers.
