Classic 3-Ingredient Sponge Cake

1. Beat eggs in a mixer until creamy

2. Gradually add sugar while beating

3. Gradually add the sifted flour while beating

4. If using, add baking powder and gently fold in with a whisk

5. Pour the batter into a greased and floured 9-inch cake pan

6. Bake in a preheated oven at 350°F (180°C) for 25 to 35 minutes or until a toothpick inserted comes out clean

Notes

1. This batter rises significantly even without baking powder so it is optional
