In a bowl, mix all the ingredients, adding the flour last along with the baking powder. Grease the pan with butter, pour in the mixture, and arrange the apple slices in a circular pattern on top. Place almonds in the center if desired, and bake in the oven.

Once baked, brush with jam and return to the turned-off oven to let the jam soak in. Enjoy! 😋😋😋👍
