Pao De Lo (Sponge Cake)

Directions

1. 1
   1. Heat oven to 375 degrees F. Lightly grease 9-inch round cake pan or nonstick madeline pan. Cut a 15-by 12-inch piece of parchment paper and fit into pan, allowing edges to extend beyond rim(see Note). Grease paper on bottom and 2 inches up side of pan.

   3. Sprinkle flour over egg mixture. With rubber spatula, very gently fold flour into beaten egg mixture until uniformly combined. Spread batter into prepared pan. Place another piece of parchment over cake, resting on extended edges of the parchment pan liner and being careful to avoid top of batter.

   4. Bake 15 minutes or until center appears set. Remove top piece of parchment. Cool cake in pan on wire rack 15 minutes. Using edges of parchment pan liner, lift cake to serving plate and set aside at least 1 hour before serving.

   Note: The cake may be baked without parchment, but the surface will be darker. To do so, grease 9-inch round baking pan and line bottom with a circle of waxed paper; grease paper and side of pan.
