If you don't have a blender or a food processor you can always mix by hand without using peanutbutter, your going to want to wisk the eggs first though. So put all ingredients in blender and blend for about 1 minute,then grease muffin pan and pour till 3 quarters full. Then sprinkle in whatever you want if your not going to sprinkle anything in them then fill the muffin cups to the rim you can also you cupcake liners instead of greasing the pan.
