Baumkuchen

Allow egg yolks, egg whites, and butter to stand at room temperature for 30 minutes. Meanwhile, grease an 8-inch springform pan; set aside.

Preheat broiler. In a medium mixing bowl beat egg yolks with an electric mixer on high speed about 5 minutes or until thick and lemon color; set aside. In an extra-large mixing bowl beat butter on medium to high speed for 30 seconds. Gradually add 3/4 cup sugar, lemon peel, and vanilla. Beat until combined, scraping sides of bowl occasionally. Add beaten egg yolks, beating until combined. In a small bowl stir together flour, cornstarch, and salt. Stir flour mixture into egg yolk mixture just until combined.

Thoroughly wash beaters. In a large mixing bowl beat egg whites on medium speed until soft peaks form (tips curl). Gradually add 1/4 cup sugar, beating on high speed until stiff peaks form (tips stand straight). Fold beaten egg whites into egg yolk mixture.

Pour 1/3 cup of the batter into the bottom of the prepared pan, spreading evenly. Broil about 5 inches from the heat for 1 to 2 minutes or until light brown.* (If necessary, give pan a half-turn for even browning.) Do not overbrown. Remove from broiler. Pour another 1/3 cup of the batter over top of first layer, spreading evenly. Broil as directed, turning pan if necessary. Repeat with the remaining batter, making 15 to 17 layers total. Cool in pan on a wire rack for 10 minutes. Loosen cake from sides of pan. Remove sides of pan; cool cake completely on wire rack.

Cut cake into 12 wedges. Place wedges on a wire rack set over waxed paper. Spread Vanilla Glaze over tops of wedges, letting some of the glaze drip down the sides. Drizzle wedges with Caramel Glaze. Let stand until set.
