For the filling:
1 heaped cup of sliced apples (I have pitted and quartered them and then sliced them)
1/3 cup of sugar
1/4 teaspoon cinnamon
a little bit of freshly grated nutmeg
2 tablespoons of cornstarch
2 teaspoons of water
1/2 cup of brown sugar (I used 1/4 cup of dark and light sugar)
1/2 teaspoon cinnamon
For the cake:
1/3 cup of butter
3/4 cup of sugar
1/2 cup applesauce
1 teaspoon vanilla
2 1/4 cups flour
1 teaspoon baking powder
1 teaspoon baking soda
1 teaspoon of salt
1 teaspoon cinnamon
1 cup of Greek yogurt (you can also use plain yogurt or sour cream)
2 cups of powdered sugar
1 teaspoon vanilla
6 tablespoons of milk
For the filling: Make your filling by combining apples, sugar, water, cinnamon and corn starch in a small saucepan. Simmer for 5 to 7 minutes, stirring constantly until the sauce thickens and the apples are a little soft. Let them cool. In a small bowl, mix the brown sugar and cinnamon until well combined and set aside.
For the cake: Preheat the oven to 350°. Grease and flour a 9×13 baking dish. Set aside.
Cream butter and sugar until light and fluffy, about 3 minutes. Add the applesauce and vanilla and mix until combined. Add the eggs, one by one, beating well after each addition.
Close the dry ingredients together. Add the dry ingredients to the dough in three parts, alternating with the yogurt in two parts, starting and ending with the dry ingredients. Beat until well combined.
Place half of the dough on the prepared tray. Place the cooled apple mixture on the dough carefully and spread it as evenly as possible. Sprinkle 2/3 of the brown sugar and cinnamon mixture over the apples and cover them with the rest of the dough. Sprinkle the rest of the brown sugar and cinnamon mixture over the top.
Bake for 45-55 minutes, until a toothpick inserted in the center of the cake comes out clean.
For the icing: While baking the cake, make the icing. In a bowl, mix the powdered sugar, vanilla and milk until the glaze is the desired consistency. When the cake comes out of the oven, immediately but carefully, pour it over the hot cake. Try to pour it as evenly as possible. You may have to take the cake and tilt it to spread the icing evenly. I even poured a little bit that accumulated in the corners and I saw it again on top. Let the cake settle for a while so that the icing sets
