Szarlotka (Polish apple cake)

The traditional Polish apple cake was one of the first cakes I have ever learned how to make. My grandma was downright ecstatic when I displayed interest in learning how to cook and bake. That being said, this is a relatively labor intensive cake. It will take you a couple of hours to put together, that's for sure.

Ingredients:

• 4 eggs (whites and yolks separated)
• 4 sticks of unsalted butter, room temperature
• 2.5 cups of sugar (3.5 cups if you like super sweet things)
• approx. 1lbs of flour
• 3 teaspoons of baking powder
• 1/4 teaspoon of salt
• 2 tablespoons of sour cream (if necessary)
• 6 large Granny Smith apples
• 1 teaspoon of vanilla extract

You will need a 9x13 baking pan, a variety of mixing bowls, a pot, and cooking spray. 

Preparing the dough: Combine all the flour, 2 tsp of baking powder, salt, and a cup of sugar in a large bowl. Add the butter and 4 egg yolks, and knead the dough with your hands until it becomes uniform (I'm sure this could be done in a mixer, but I do not possess one). If the dough comes out too dry, add some sour cream until the dough no longer crumbles. Wrap it in plastic wrap and freeze it for an hour.

Preparing the apple layer: Peel the apples and grate them; you can either do it by hand or run the apples through a juicer and put everything back together. The choice is yours. Put the grated apples into a pot, add a cup of sugar, and simmer until the apples have completely softened. Optionally, you can add a tbsp of cinnamon to apples. Set aside and let it cool completely.

Preparing the whipped layer: Put 4 egg whites into a sturdy bowl and whip them into foam with hand mixer until you have soft peaks. Add 1 tsp of baking powder, 1 tbsp of flour and 1/2 cup of sugar while stirring carefully with a spoon.

Preheat the oven to 350F.

Assembling the cake: Grate 3/4 of the frozen dough onto the baking pan and stick the rest back into the freezer. Bake that for about 25 minutes, or until the top is just barely baked (it will start showing golden edges). Take out the pan. Pour the apple layer onto the cake layer and smooth out. Pour out the whipped layer onto the apples and also smooth out evenly. Grab the remaining frozen dough and grate it on top of the whipped egg whites. Try to cover as evenly as possible, even if the grated dough will try to splatter everywhere. Put the pan back in the oven and bake for another 20 minutes. Let it cool before serving.

Enjoy!
