Easy and delicious gluten free apple cake – Easy and gluten free

Ingredients

• 150 g butter – at room temperature
• 130 g sugar (I use brown sugar)
• 1 teaspoon vanilla sugar
• 3 eggs
• 150 g gluten free flour – I find Doves Farm self-raising flour is ideal for this cake; if you don't have that one, Schaer Mix C works well too
• 1 teaspoon baking powder – only if you are not using self-raising flour!
• 60 g milk
• a pinch of salt
• cinnamon (optional)
• 1 cooking apple
