In a blender, pour the espresso (or coffee made with a machine) and the cinnamon, nutella, and peanut butter. Blend until the nutella and peanut butter isn’t thick and visible anymore. If you have a blender with a removable top, blend and pour in the maple syrup slowly. If you have a blender with a solid lid (like me) just pour a bit of the maple syrup, blend, pour a bit, blend etc etc.
