Apple cake

Core and seed the apples and cut them into 1 cm cubes. Whisk the eggs with sugar until foamy. Continuing to whisk, add the flour, baking powder, and cinnamon and properly stir until smooth. Grease the bowl with the butter, and put half of the dough inside. Add the apples and cover with the rest of the dough. Close the lid and remove the steam valve. Select BAKE. Set the time for 50 minutes. Cook until the programme finishes.
