Use your hands to knead the pretzel dough for 4-5 minutes until you can form it into a ball. You could also use a stand mixer with a dough hook attachment.
Add flour to a large cutting board (or surface) and cut the dough into 4 pieces. Roll out each section into a long rope about 1/2-inch thick and about 1-foot long.
Stir together the sweetener and cinnamon. Spray the pretzel bites generously with nonstick cooking spray and add them to a bowl. Toss with the cinnamon-sugar mixture
