Bobby's Lighter Simply Delicious Strawberry Cake

Preheat the oven to 350 º degrees. Spray two 9-inch round cake pans with nonstick spray. Line with wax-paper rounds; spray with nonstick spray. Puree the strawberries and 3 tablespoons of jam in a food processor. Set aside. Combine the cake mix and gelatin in a large mixing bowl. Beat in the strawberry puree, egg whites, oil and water with hand mixer at medium speed until thickened, about 2 minutes. Divide the batter evenly between the pans. Bake until a wooden pick inserted in the center comes out clean, about 20 minutes. Let cool in pans 10 minutes. Invert the layers onto racks and remove the wax paper; let cool completely. For the frosting: With clean beaters, beat the cream cheese and butter in a medium bowl with a hand mixer until creamy, about 2 minutes. Beat in the 1/4 cup of jam and the strawberry extract. Gradually add the confectioner's sugar, beating until smooth. Place 1 cake layer on a serving plate. Spread 1/3 of the frosting over the cake layer. Top with the remaining layer. Spread the remaining frosting over the top and sides of the cake. Garnish with the strawberries, if using.
