Prepare the Yeast Mixture: In a small bowl, pour warm water and sprinkle active dry yeast over the surface. Stir in granulated sugar and let it sit until frothy.

Combine Dry Ingredients: In a large mixing bowl, whisk together all-purpose flour and salt. Make a well in the center for the yeast mixture.

Mix and Form the Dough: Pour yeast mixture and melted butter into the flour mixture. Mix until shaggy, then knead for 5 to 7 minutes.

Allow the Dough to Rise: Shape dough into a ball, place in a greased bowl, cover, and let rise for 1 to 1.5 hours.

Shape the Pretzels: Punch down dough, divide into 8 pieces, roll each into an 18-inch rope, twist into a pretzel shape.

Preheat the Oven: Preheat oven to 375°F (190°C).

Boil the Pretzels: Boil water with baking soda, drop in pretzels for about 30 seconds, turning halfway.

Prepare for Baking: Transfer boiled pretzels to a parchment-lined baking sheet. Brush with beaten egg.

Sprinkle with Cinnamon Sugar: Combine granulated sugar and ground cinnamon, sprinkle over pretzels.

Bake to Perfection: Bake for 12 to 15 minutes until golden brown.
