1.
Preheat oven to 350 degrees Fahrenheit.
2.
Beat egg whites until soft peaks form. With mixer on high speed, slowly add one cup sugar until stiff peaks form.
3.
Lower the mixer to the lowest speed and add egg yolks, oil, potato starch, orange juice, lemon juice, and vanilla sugar. Mix until just combined.
4.
Mix apples with remaining 2/3 cup sugar and cinnamon.
5.
Pour half the batter into a 9 x 13-inch pan lined with Gefen Parchment Paper. Carefully lay the apple slices over the batter, discarding any liquid that has accumulated. Pour the rest of the batter over the apples.
6.
Bake for about 55 minutes, until top is lightly browned and puffed. Once cake has cooled, top with a light layer of sifted powdered sugar.
This calls for 4 tips cinnamon. It seems like a lot. Is it correct?
That does sound like a little much. I’d recommend starting with 1 tsp and adjusting from there. It’s always easier to add more if needed!
Instead of me guessing.. is it possible to ask the person who submitted the recipe for the correct amount?
