Apple squares

Here's my mother-in-law's recipe, for apple squares - a basic sheet cake covered in thin apple slices, and cinnamon. Per loves these, and they're really easy to make a lot of. They freeze very well and defrost in minutes. Feel free to augment proportions if you want a higher cake, these are pretty flat. (My oven, and thus baking sheet, is bigger than hers. I used 1.5 times her original recipe, but perhaps I'll double it next time.)

Apple squares
about 24

3 eggs

300 ml sugar

150 ml milk

450 ml flour

2 tsp vanilla sugar

2,5 tsp baking powder

180 g butter, melted

4-5 apples

cinnamon

Beat eggs and sugar on high speed until very pale and fluffy. Stir in milk and flour, alternating between the two. Add the vanilla sugar and baking powder. Finally, stir in the melted butter.

Pour into a baking pan lined with a baking sheet, mine was about 30*40 cm.

Core and peel the apples, and slice very thinly. Arrange on top of the batter. Lightly dust with cinnamon.

Bake at 175°C for about 15-20 minutes.
