Add flour and yogurt to stand mixer and combine on medium speed until flour is no longer visible.
Switch to a dough hook and kneed for 5 minutes until the mixture makes a ball that pulls away from the sides.
Add flour to a cutting board and sprinkle additional flour over the dough.
Press the ball into a flattened rectangle and cut it into 6 long pieces.
Using your hands (cover your hands with a bit of flour), roll the dough into logs.
Pre-heat oven to 425 degrees.
Cut each log into 8 pieces and place onto baking sheet dusted with flour.
Add water to a saucepan and bring to a boil.
Add baking soda to the pan and stir until dissolved.

Stir sugar and cinnamon together in a small bowl.
Gently remove the pretzel bits and place them into a large bowl.
Toss with the melted butter then sprinkle on the cinnamon sugar and toss to coat.
