01 - In a bowl, combine shredded chicken breast, buffalo hot sauce, melted butter, mozzarella cheese, blue cheese, sliced green onions, garlic powder, and black pepper. Mix until evenly blended and set aside.
02 - In a large mixing bowl, dissolve active dry yeast and granulated sugar in warm water. Leave for 5 minutes until foamy.
03 - Add all-purpose flour, salt, and melted butter to the yeast mixture. Mix thoroughly to form a soft dough.
04 - Transfer dough to a floured surface and knead for 5–7 minutes until smooth and elastic.
05 - Place dough in a greased bowl, cover, and allow to rise in a warm spot for 30 minutes until doubled.
06 - Preheat oven to 425°F. Line a baking sheet with parchment paper.
07 - Punch down the risen dough and divide into 24 equal portions. Flatten each piece into a 3-inch disk.
08 - Place about 1 tablespoon of buffalo chicken filling in the center of each disk. Pinch the edges tightly to seal and form into a smooth ball.
09 - In a large pot, bring 8 cups water and baking soda to a boil, then reduce to a gentle simmer.
10 - Gently lower 4–6 balls at a time into the simmering bath for 30 seconds. Remove using a slotted spoon and transfer to the parchment-lined baking sheet.
11 - Brush each pretzel ball with beaten egg and sprinkle with coarse salt.
12 - Bake in the preheated oven for 13–15 minutes until balls are golden and crisp. Serve warm with extra buffalo sauce or ranch dressing if desired.
