Place all of the ingredients, except for the toppings, inside a high powered blender in the order listed. If you're using an apple, add 1 teaspoon of ground cinnamon. Blend on high until smooth.
Carefully spoon the batter into the mini muffin pan, filling the cups 1/2 to 3/4ths full. If desired, sprinkle with optional toppings. My favorites are dairy free chocolate chips, granola, and fresh fruit.
Place the muffin pan inside the oven and bake for 9 to 11 minutes or until a toothpick inserted in the center comes out clean.
