Fluffy Sponge Cake With Apples Recipe

Fluffy sponge cake with apples is my mom-in-law’s version of Polish szarlotka. It’s quick to make, and if done right, it’s really soft. No wonder it’s called “puch” (fluff) in Polish.

My mom-in-law says that she remembers her mom baking this cake. It never got to cool off because the entire family ate it up when it was still warm. 

Tips For Making Fluffy Sponge Cake With Apples

Stir In One Direction Only.

Beaten egg whites are very delicate. Make sure you are stirring really gently when adding the egg yolk mixture and flours. It’s the only way to make the cake fluffy.

Sprinkle The Apple Sponge Cake With Powdered Sugar.

The apple sponge cake tastes best when served with powdered sugar. If it’s too sweet to you, you may eat it solo.

Add More Or Less Apples If You Want.

The number of apples you add to this sponge cake is totally up to you!

Make It Any Shape You Like.

You can either bake this apple sponge cake in a rectangular, round, or square baking tray.
