You can sub 1 1/2 cups of strawberry jam for the puree
1pintfresh strawberries, washed and hulled
4limes, for 1/2 cup fresh lime juice
1 (14-ounce)cansweetened condensed milk
2cupsheavy whipping cream
Whipped Cream Frosting:
2cupsheavy whipping cream
1envelopeabout 2 teaspoons unflavored gelatin
For the cake, preheat the oven to 350 degrees F. In a large bowl, combine the flour, sugar, baking powder, baking soda and salt. Add buttermilk, butter and vanilla. Beat with an electric mixer on low speed for 30 seconds, scraping the bowl as needed. Increase the speed to medium and beat for 2 minutes. Add the egg whites and beat for 2 minutes more, scraping down the sides of the bowl as needed.
Pour the batter into 2 greased and floured 9-inch round cake pans. (I lined the bottom of mine with a parchment circle and greased the top of the parchment circle.) Bake the cakes for 28-30 minutes until a toothpick inserted near the center comes out with moist crumbs. Don’t overbake or the cakes will be dry. Cool the cakes on a wire rack for 10 minutes. Loosen the sides with a butter knife and remove the cakes from the pans to cool completely.
For the strawberry puree, combine all the ingredients in a blender and process until smooth.
For the lime cream, zest and juice the limes into a medium bowl. You should have about 1/2 cup lime juice. Add the sweetened condensed milk and mix well. Add the whipping cream and beat until medium-stiff peaks form. Cover with plastic wrap and refrigerate until needed.
For the whipped cream frosting, in a small bowl, place the water and sprinkle the gelatin over the top. Let the mixture stand for 3-4 minutes until the gelatin has thickened. Microwave for 20-30 seconds until the gelatin dissolves and the mixture is warm. Remove from the microwave and let the mixture cool to room temperature (don’t let it set up!). In a large bowl, whip the cream, sugar and vanilla until slightly thickened. While beating slowly, gradually add the cooled gelatin to the whipped cream mixture. Whip at high speed until stiff peaks form.
To assemble the cake, slice each cooled cake round in half horizontally to form 4 cake circles. Place one cake layer on a cake plate and spread an even layer of strawberry syrup over the top. Spread a thick layer of lime cream over the jam, leaving a 1/2-inch border around the edge as the top cake layers will press the cream out toward the edges. Repeat the same layering process with the next two layers. Top with the final cake layer and frost the entire cake with the whipped cream frosting. Garnish with fresh limes and strawberries, if desired. Chill for 1-2 hours before serving to let the cake set up.
Multiple Steps: this recipe looks like it has a lot of steps, and it does, but each can be made in advance and the cake assembled later. Plus, none of the steps are very difficult. The end result is worth it, trust me!
