01 - Combine warm water, yeast, and 1 tablespoon sugar in a large bowl. Let stand for 5 minutes until mixture becomes foamy and fragrant.
02 - Add melted butter, flour, and salt to the yeast mixture. Stir until a shaggy, sticky dough forms and all flour is incorporated.
03 - Knead by hand on a lightly floured surface or use a stand mixer with dough hook for 5–7 minutes until dough is smooth, elastic, and springs back when pressed.
04 - Place dough in a lightly greased bowl, cover with plastic wrap or a clean towel, and let rise in a warm, draft-free area for 1 hour until doubled in size.
05 - Preheat oven to 450°F. Line two baking sheets with parchment paper and set aside.
06 - Bring 10 cups water and baking soda to a rolling boil in a large pot. The mixture will foam—ensure pot is large enough to prevent overflow.
07 - Turn risen dough onto a lightly floured surface. Divide into 8 equal portions. Roll each piece into a 20-inch rope, then shape into a traditional pretzel form by crossing ends and twisting them down.
08 - Carefully lower each pretzel into the boiling baking soda bath for 30 seconds. Remove with a slotted spatula, allowing excess liquid to drain, then place on prepared baking sheets.
09 - Bake pretzels for 12–15 minutes until deeply golden brown with a shiny, crisp exterior.
10 - While pretzels are still warm, brush each generously with melted butter to ensure cinnamon sugar adheres properly.
11 - Whisk together granulated sugar and ground cinnamon in a shallow bowl. Roll each buttered pretzel in the mixture, pressing gently to coat all sides evenly.
12 - Serve immediately while warm for the softest texture and best flavor experience.
