In a microwave-safe bowl, warm the milk in the microwave for about 1 minute, until it's between 98?F to 105?F. In a large mixing bowl, whisk the warm milk with the brown sugar, instant yeast, melted butter, pumpkin puree, and two eggs.

Add the flour, pumpkin pie spice, and salt. Mix with a large wooden spoon until it starts to form a cohesive dough.

On a lightly floured work surface, knead the dough by hand for about 5 minutes, until the dough is smooth and elastic. Alternatively, knead the dough in a stand mixer with a hook attachment for about 3 minutes.

Place the dough ball back in the mixing bowl and cover it with a clean kitchen towel. Let the dough rise in a warm spot until it has doubled in size, after about 1? to 2 hours.

Line a baking sheet with parchment paper. Cut 12 strands of baking string, each at least 3 feet long. Coat the baking string in olive oil or spray them with cooking spray to prevent them from sticking to the bread.

Divide the dough into 12 even-sized pieces and roll them into smooth balls. Keep them covered with a clean kitchen towel.

Place one ball in the middle of a piece of baking string. Bring the ends of the string over the ball, cross them, and bring them down to divide the ball into quarters. Tuck the string under the ball, bring the ends back up, cross them, and bring back down to divide the ball into eighths. Tie the string on the bottom of the ball and trim off any extra string.

Repeat with the remaining dough and arrange the string-tied dough balls on your prepared baking sheet.

Cover with a clean kitchen towel and set aside to proof for 30 minutes, until the dough balls have puffed up against the string.

Preheat the oven to 350?F. Whisk one egg white with one teaspoon of water in a small bowl to make an egg wash. Once the rolls are done proofing, brush the tops and sides of each roll with the egg wash.

Bake the rolls for 20 to 25 minutes, or until they are golden.

Let the rolls cool for a few minutes, then cut and remove the baking string. Gently press the pretzel sticks into the top of each roll to create the pumpkin stem.
