4 to 5 granny smiths or other firm cooking apples, 125g butter (lightly salted), 100g sugar, 2 medium eggs, 1 level tbs baking powder, 200g white plain flour
Peel, core, halve, and lightly cut criss-cross pattern into outside of the apples.
Preheat oven to 160 Celsius (fan, add 20 degrees C for conventional oven).
Butter 25 to 28 cm spring form.
Melt butter but take care not to let it turn brown. Pour into mixing bowl and allow to cool slightly. Separate eggs and add yolks and sugar to the butter. Mix on high until mixture turns light yellow in colour and slightly fluffy.
Add 1/3 of the flour and the baking powder. Mix well. Add some of the egg white and mix until smooth. Add next third of flour, mix, add remaining egg white, mix until smooth. Add remaining flour and mix well.
Spread mix which should be reasonably sticky with a tbs in the cake form. Place the apple halves outside facing up on the cake mix and push in about a cm. Sprinkle the cake mix and apples with some sugar to caramelise (if you like, with a bit of cinnamon, too, which works well with apples).
Place in the middle of the oven and bake for 40 to 45 minutes. Check if the cake is done by pricking with a long needle. If it comes out without cake mix sticking to it, it is done. Alternatively, knock on the bottom of the cake tin. Be careful, it's hot! If it sounds hollow, the cake is also done.
Allow to cool. Eat cold on its own or with whipped cream. Enjoy! :-)
