In the bowl of a stand mixer, combine the warm water, yeast, and sugar. Let sit for 5 minutes, or until bubbly. If the mixture does not foam, the yeast is inactive and the pretzels will not turn out. Repeat this step with fresh yeast until bubbly.
1 cup warm water, 1 pkg dry active yeast, 1 Tbsp sugar
Add 1Tbsp melted butter, salt, and flour. Using the dough hook, knead on low speed for 10 minutes. The dough should be very soft but not stick to the sides of the bowl.
1/4 cup + 1 Tbsp melted butter, divided, 1/2 tsp salt, 2 1/2 cups flour
Cover and let rise at room temperature for 1 hour, or until doubled in size
After the dough has doubled, punch down and divide into 8 equal pieces. Set aside and preheat the oven to 425°F.
In a large pot, bring the water and baking soda to a boil.
4 cups water, 2 Tbsp baking soda
Roll each piece of dough into a long rope, then cut into 1-inch pieces to form bites.
Working in batches, gently drop the dough pieces into the boiling baking soda water for 5–10 seconds. Remove with a slotted spoon and place on a parchment-lined baking sheet. (The parchment will become wet, so be sure to transfer the bites to a fresh sheet of parchment before baking.)
Bake for 10 minutes at 425°F.
Remove from the oven and immediately dip in the remaining ¼ cup melted butter, then toss in the cinnamon-sugar mixture until coated.
1/2 cup cinnamon and sugar mixture
These are best enjoyed within the hour and served with vanilla icing!
