Preheat the oven to 180°C (350°F) and line a muffin tray with 8-10 muffin liners.
Place all the dry ingredients into a large bowl and mix together.
Melt the coconut oil and place in a bowl with all the wet ingredients and mix thoroughly together.
Mix the wet ingredients into the dry and mix well.
Stir in 2/3 of the chopped apple.
Pour into the muffin cases until each one is 2/3 full.
Sprinkle the remaining apple over the top of each one.
Bake for 20 minutes or until a skewer inserted comes out clean.
Allow to cool for 10 minutes before serving
You can use an electric mixer to mix the batter. If not using an electric mixer, you may need to use a whisk as the coconut flour will clump up when the wet ingredients are added. This makes 8-10 muffins depending on the size and shape of your muffin tray.Adapted from Paleo Grubs by Rebecca Bohl
