Assemble Pretzels:
Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
Punch down risen dough and divide into 8 equal portions.
Flatten each portion of dough into a disk. Place a frozen cookie dough ball in the center of each disk and wrap dough around it, pinching edges to seal.
Roll each stuffed dough ball into a pretzel shape.
Baking Soda Bath:
In a large pot, bring water and baking soda to a boil.
Carefully drop each pretzel into boiling water for 30 seconds. Remove with a slotted spoon and place on prepared baking sheet.
Bake Pretzels:
Brush pretzels with beaten egg and sprinkle with coarse sea salt.
Bake for 12-15 minutes, or until golden brown.
Serve: Let pretzels cool slightly before serving. Enjoy warm for the best gooey cookie center.
