Grease a Bundt cake pan with some coconut oil and sprinkle some coconut flakes to prevent the top of the cake from sticking. Set it aside.

Melt the butter over a low heat.

Make sure the butter doesn't burn. Set it aside to cool off.

Preheat the oven to 350° Fahrenheit or 180° Celsius.
Wash, peal, and slice the apples.

Sprinkle the apples with lemon juice and cinnamon. Set them aside.

Using two mixing medium bowls, separate the egg yolks and the egg whites.

Beat the egg whites with a hand mixer until stiff and fluffy.

Next, beat the egg yolks with powdered sugar, brown sugar or honey, vanilla, and salt.

Beat them thoroughly until you obtain a creamy and fluffy texture.

Gently fold in the egg whites.

Measure two cups of flour. Add the potato flour, baking powder, and baking soda and mix it thoroughly together.

Slowly add the mixed flour to the combined egg mixture as you gently mix the batter.

Next, slowly pour in the cooled butter as you mix the batter gently using a spatula.

Once the ingredients are combined into a uniform batter, add the apples.

Pour the batter into the earlier greased Bundt cake pan.

Put it in the preheated oven and bake for 45 minutes.
Remove the apple Bundt cake from the oven and let it cool for 10-15 minutes.

Slowly turn the apple Bundt cake pan while pressing the plate on top, and once turned, lift the form as you place the apple Bundt cake onto the plate.

Sprinkle some powdered sugar on top and enjoy!
