Preheat oven to 400F.
Place all ingredients except the chocolate chips in a blender. Blend mixture approximately 30-45 seconds or until completely smooth.
Using a spatula scrape down the edges of the blender and blend again for 20 seconds.
Add half the chocolate to the blender and pulse to break them up.
Spray a standard muffin tin with cooking spray and scoop batter into muffin tin (I use an ice cream scoop). Top with the remaining chocolate.
Bake 12-14 minutes or until muffins have set.
