Peel the apples and cut them into smaller pieces
Put apple, sugar, and water in a saucepan and cook under lid on medium heat until the apples are tender
Remove the apples from the heat and use a hand blender to mash them into apple sauce
In a large bowl, mix flour, baking powder, and baking soda
Whip the oil with the flour with a whisk – this might create small lumps
Zest the lemon using a grater with fine holes
Press lemon juice of 3-4 lemons (till there are 1 ½ dl)
Add apple, lemon zest, and lemon juice to the flour and stir it quickly together. The dough will already start to rise due to the lemon juice (which naturally contains acid)
Put cupcake liners in a muffin pan
Pour dough into each cupcake liner till they are full
Bake the cake in the oven at 175° C for 15-20 minutes
Let the cakes cool
