Strawberry Shortcake
Preheat oven to 425° F.

Place shortcake ingredients in large bowl and stir until just combined. Pour into two greased and floured 8-inch round cake pans. Bake in oven for 20 minutes, or until cake tester inserted in center comes out clean.

Sprinkle 4 tablespoons sugar over strawberries in one bowl. Combine yogurt, sour cream, vanilla, and 2 teaspoons sugar in another bowl.

Remove shortcake from pan by running a knife around the edge and inverting. Spread half of the strawberry mixture on one layer of shortcake. Place the other shortcake layer on top. Top with remaining mixture. Before serving, top with yogurt and sour cream mixture.
