Preheat the mini waffle maker.

Put the egg white in a medium bowl and beat on high speed with a hand mixer until stiff peaks form. Turn the mixer to low and add the protein powder and cinnamon. Add the extract and stir well to combine, being careful not to deflate the whites.

Spray the mini waffle maker with coconut oil spray. Spoon half of the mixture into the center of the waffle maker. Cook until firm and golden brown, 2 to 3 minutes. Repeat with the remaining half of batter.

Top each waffle with 2 tablespoons of pudding and a sprinkle of cinnamon, if desired. Serve immediately.
