Wash celery under running water and dry with paper towel. Cut off ends of celery and then cut each celery rib in half to make 10 celery rib halves.
Spread peanut butter into each celery rib.
Stick each pretzel half to the peanut butter on one end of the celery to look like antlers
Add candy eyes and rasberry for nose.
Notes
Substitute the peanut butter for almond or sunflower seed butter for a different flavor.Adapted from Fork and Beans - https://www.forkandbeans.com/2016/12/12/peanut-butter-celery-reindeer-sticks/
