Apple Cake

3,4 Red delicious or Gala Apples, cut into bite size pieces (not too small or too big)
200gm unsalted butter (2 sticks), at room temperature
4 eggs (large)
200 gm All Purpose Flour
2½ tsp Baking Powder
200 gm Sugar
2 tsp Vanilla Extract

Preheat the oven to 375F. Grease the pan well with butter/PAM. Cut the apples in advance, doesn't matter if they discolor while you prepare the batter.
Cream butter, sugar very nicely until double in volume. Add eggs and vanilla and beat till smooth and well blended.
Gently mix the flour and baking powder in a separate bowl.
Add flour-mixture to the wet-mixture slowly until well blended. Take care not to over mix the dough. The batter should be really soft now. Fold in the apples.
Pour into the pan and bake for 45 min, check if done by inserting a toothpick in the center of the cake. If needed, bake cake for 10 min more. Cool cake for 20 min and then place a plate over the pan and invert. Serve with runny custard.
