Directions

1. In a large bowl, combine the berries, sugar and lemon juice. Cover and refrigerate for 1 hour. Gently press berries; drain, reserving juice. Set berries aside.

3. In a large bowl, combine the flour, 1 cup sugar, baking powder and salt.
4. Whisk egg yolks, water and oil; add to dry ingredients, beating until smooth.
5. In another bowl, beat egg whites on medium speed until soft peaks form. Gradually add remaining sugar, beating on high until stiff peaks form; fold into batter.
6. Spread into an ungreased 9-in. springform pan.
7. Bake at 325° for 30-38 minutes or until cake springs back when lightly touched. Cool for 10 minutes; remove from pan and cool on a wire rack. Meanwhile, in a large bowl, beat cream cheese and confectioners' sugar until smooth. Fold in whipped cream; set aside.
8. Cut cake horizontally into three layers.
9. Place bottom layer on a serving plate; spread with a third of the filling. Top with a third of the berries; drizzle with 1/4 cup berry syrup. Repeat layers twice, drizzling with remaining syrup. Refrigerate for at least 2 hours before serving.
