Whisk the eggs until pale, then add the oil and continue whisking. Add the yogurt and whisk again. Add the flour and baking powder, and mix with a spatula until the batter is smooth.

Arrange the apple slices in a baking pan lined with parchment paper and pour the caramel sauce mix over them.

Bake at 350°F (180°C) for 40 minutes.

Enjoy!
