1¼ cups whole milk
5 eggs, separated, save whites
¼ cup vegetable oil
2 cups flour
1 cup powdered sugar
1 tablespoon baking powder
2 cups of raspberries; or fruit you would like.
1 lemon, zested & juiced
1 teaspoon salt
Powdered sugar, for dusting
Preheat oven to 375 degrees F. Grease the Emile Henry Deep Rectangular Tart Dish and set aside. Toss raspberries in one to tablespoons flour and set aside.
In a medium bowl, whisk together the flour, powdered sugar, baking powder, lemon zest, and salt. Set bowl aside. Separate eggs yolks from whites into two small bowls. In a stand mixer beat the egg whites on a 10 for 2 to 3 minutes until they form stiff white peaks. You may also hand whisk the egg whites.
In a large bowl, whisk together milk, egg yolks, lemon juice, and vegetable oil until the batter is smooth like silk. Slowly whisk in dry ingredients with the wet until the batter is smooth. Using a spatula, fold in the egg whites slowly and carefully. Do not over mix.
Bake for 30-35 minutes or until a small butter knife inserted into the center comes out clean. Cool to room temperature and sift powdered sugar over the top of the cake. Serve in small squares.
