Activate yeast by combining warm milk, brown sugar, and yeast in a large bowl. Let sit for 5-10 minutes until frothy and bubbly. If nothing happens, your yeast is dead—start over.

Make dough by stirring melted butter and salt into yeast mixture, then gradually adding flour until soft dough forms. Knead for 5-6 minutes until smooth and elastic. Cover and let rise for 1 hour until doubled.

Prepare filling by mixing pumpkin puree, both cheeses, garlic powder, smoked paprika, salt, and pepper in a bowl until creamy and smooth. Refrigerate for 15 minutes to firm up slightly.

Divide dough into 20 equal pieces after punching down risen dough. Keep pieces covered with a damp towel while working to prevent drying out.

Shape bites by flattening each piece into a 3-inch circle, adding 1 teaspoon filling to center, and pinching edges tightly to seal. Roll into smooth balls with seam side down.

Boil water bath by bringing 6 cups water and baking soda to a boil in a large pot. The baking soda creates that characteristic pretzel crust and flavor.

Boil pretzel bites by dropping 4-5 balls at a time into boiling water for exactly 30 seconds. Remove with slotted spoon and place on parchment-lined baking sheet.

Brush with butter and sprinkle generously with coarse sea salt while pretzel bites are still wet from boiling. The moisture helps salt stick perfectly.

Bake at 400°F for 12-15 minutes until deep golden brown and puffed. The baking soda bath creates beautiful color during baking. Don't underbake or texture will be doughy.

Finish with butter by brushing hot pretzels with more melted butter immediately after baking. Sprinkle with fresh parsley if desired and serve warm for best texture.
