Preheat your oven to 350F.
Dice up your apple, and either on the stovetop or in the microwave, heat fro 2-3 minutes until it is soft. Drain any excess liquid from the bowl the apples cooked in.
In a large blender, add all the ingredients. Blend until a thick batter forms.
Lightly grease a 24-muffin mini-muffin tin. Pour the batter into each tin, filling about 3/4 of the way up.
Bake at 350F for 16-18 minutes.
