This delicious apple sponge cake is one of the easiest and most delicious apple desserts you can make. It is light, sweet, and requires only a few ingredients. It's my go-to dessert for unexpected guests or as a sweet treat to enjoy with your tea on a chilly day.
Preheat oven to 350°F. Grease a 9inch spring cake pan with some butter or cooking spray, then dust with some flour. Wash, peel and slice apples. Spread apples at the bottom of the pan.
In a mixing bowl, sift 1 cup and 2 Tablespoons of flour with a ½ teaspoon of baking powder.
Using a hand mixer, beat 4 eggs with a pinch of salt for one minute. Slowly pour 1 cup of sugar while mixing on high. Beat eggs and sugar for 10-12 minutes on high speed until the ribbon is left on the surface when you pull up the mixer whisk. The volume should be tripled.
Using a silicone spatula, gently fold in the sifted flour in three batches. Now, gently mix in 1 teaspoon of vanilla extract.
Pour the cake batter over the apples. If needed, use a spatula to spread the batter on top of apples.
Bake at 350F for about 40-45 minutes until the top is golden. Use a toothpick or a cake tester to check if the cake is ready.
Cool down the cake for 15 minutes. Remove from the pan and dust it with some powdered sugar.
