From the brilliant minds of Matt Lewis and Renato Poliafito, this cake is the end-all-be-all of strawberry cakes. The beautifully tender crumb has a subtle, shortcake-like flavor, and the buttery, flour-based vanilla frosting complements berries nicely.

Instructions
Cake:
  1. Preheat oven to 325 degrees (F).
  2. Prepare three, 8-inch round pans, buttering the bottoms and sides and lining the bottoms with parchment.
  3. Pulse the strawberries in a food processor until mostly pureed, but with a few remaining larger pieces. Set aside.
  4. Use a fine-mesh strainer over a large bowl to sift together cake flour, all-purpose flour, baking powder, baking soda and salt. Set aside.
  5. In a smaller bowl, combine ice water, milk and buttermilk. Set aside.
  6. In the bowl of your stand mixer, add the butter and shortening. With the paddle attachment, beat on medium speed until creamy. This will take a couple of minutes.
  7. Add the sugar and vanilla, and beat until light and fluffy, about 3-4 minutes.
  8. Add the egg, and beat until just combined, scraping the sides of the bowl to ensure everything mixes together.
  9. With the mixer on low, add half of the flour to the butter mixture. Beat until just combined.
  10. Slowly add the milk mixture, and again beat until just combined.
  11. Add the rest of the flour mixture. Beat until just moistened and combined, and scrape the sides of the bowl. Beat one more time to just combine. Turn the mixer off.
  12. In a large glass or metal bowl, combine egg whites and cream of tartar. Beat the egg whites until stiff peaks form and eggs are glossy. Don't overbeat.
  13. Remove the mixing bowl from your stand mixer. Using a rubber spatula, fold the egg whites carefully into the batter until no streaks of white remain. Take care not to deflate the whites.
  14. Fold in the strawberry puree. Don't over mix, your batter will be streaked and pale pink.
  15. Evenly divide the batter among the three prepared cake pans.
  16. Bake for 40-45 minutes or until a cake tester comes out clean. Cool the cakes in their pans on a wire rack for about 15 minutes.
  17. Run a thin knife around the edge of the pan to release the cake, then invert them to remove them from the pan and allow them to cool completely before frosting.
Frosting:
  1. In a heavy-bottomed, medium sized saucepan, whisk together flour and sugar.
  2. Add milk and cream, and whisk until smooth.
  3. Cook over medium heat, stirring occasionally until the mixture comes to a boil and thickens.
  4. Pour the mixture into the bowl of your stand mixer. Beat on high speed until cool, about 10 or 15 minutes. If the mixture is warm, it will melt the butter and your frosting won't work!
  5. Meanwhile, cut your butter into pieces. (I cut each stick into 12-16 pieces.)
  6. When the flour mixture is cooled, reduce the seed to low and add the butter pieces one at a time, about 10 seconds between each piece.
  7. The frosting will thicken as butter is added. Once you have added all of the butter, continue to beat until the frosting is light and fluffy.
  8. Add the vanilla and beat until just combined.
  9. Add a drop of pink or red frosting - just a little - to achieve a pale pink color.
  10. If the frosting is too soft, you can place it in the refrigerator to thicken slightly.
  11. Set aside and prepare the filling.
Filling:
  1. Finely chop the strawberries, set aside.
  2. In a cold glass or metal bowl, beat the heavy cream until thickened to a thick, spreadable consistency.
  3. Add confectioners sugar and vanilla and beat until combined.
Assembly:
  1. Place the bottom layer of cake onto a cake board, turntable or serving platter.
  2. Top with a thin layer of whipped cream.
  3. Sprinkle half of the chopped strawberries over the top of the cream, taking care to keep them in the center ⅔ of the cake. You don't want strawberries on the outer edge.
  4. Add the second layer, and repeat the whipped cream/strawberry topping.
  5. Add the top of the cake, and put cake in the refrigerator to chill for 15 minutes.
  6. Remove from refrigerator, and spread a very thin layer of frosting over the tops and sides of the cake. This is your crumb coat, and is only used to hold crumbs in place before applying your final layer of frosting.
  7. Return cake to refrigerator for another 10-15 minutes to set frosting.
  8. Add the final layer of frosting, smoothing and decorating as you see fit. Using an offset spatula will help.
  9. Garnish with strawberries. Store cake in refrigerator.
  10. Remove cake from refrigerator 30 minutes before serving.
  11. Enjoy!
