OLD-FASHIONED BERRY SHORTCAKE

Steps:

• Heat oven to 350 degrees. Butter two 9-by-2-inch round cake pans; set aside. In a large bowl, sift together flour and cornstarch; set aside.
• In the bowl of an electric mixer fitted with whisk attachment, combine eggs, egg yolks, granulated sugar, salt, and 1 teaspoon vanilla. Beat on high speed until mixture is thick and holds a ribbonlike trail on the surface when you raise the whisk, about 5 minutes.
• Place reserved flour mixture on a large piece of parchment paper. Holding paper like a funnel, add flour mixture to egg mixture. With machine running on low speed, mix until just combined. In a steady stream, immediately add oil; mix until just combined. Remove bowl from mixer; detach the whisk. Using the whisk, fold mixture several times.
• Divide batter between pans. Bake cakes, rotating pans halfway through baking time, until the centers spring back when you touch them with your finger, about 30 minutes.
• Immediately turn cakes out onto a wire rack; let stand until completely cool.
• Combine cream, confectioners' sugar, and remaining teaspoon vanilla extract in clean mixer bowl. Scrape in vanilla seeds; reserve pod for another use. Starting on low speed and increasing to medium high, whip until stiff peaks form, about 2 minutes.
• Using a serrated knife, slice cakes in half; place one layer on a serving plate. Spread one-fourth of whipped cream over the layer; arrange strawberries on top. Repeat process with remaining layers, cream, and berries. Refrigerate until serving; garnish with mint.
