For about 10 to 12 muffins, you’ll need 2½ cups of fine almond flour, 3 eggs, ⅓ cup of maple syrup or honey, ¼ cup of melted butter or coconut oil, ¼ cup of milk, 1 teaspoon of vanilla, 1½ teaspoons of baking powder, ½ teaspoon of baking soda, 1½ teaspoons of cinnamon and a pinch of salt. Add about one cup of finely diced apple, roughly one medium apple. Bring the eggs and milk to room temperature, since cold ingredients make the batter heavy and slow to rise.
