Prepare the Dough: In a large bowl, combine 3 ¼ cups of flour, 1 ⅔ cups Greek yogurt, 1 teaspoon baking powder, and 1 teaspoon salt. Mix until a dough forms.
Form a Dough Ball: Use your hands to gather the dough and form it into a ball.
Divide and Shape: Divide the dough into four equal parts. Roll each piece into a long rope, about 18-20 inches in length.
Twist the Pretzels: Shape each rope into a U, cross the ends over each other, and press them down at the base of the U to form a pretzel shape.
Prepare for Baking: Place the pretzels on a baking sheet lined with parchment paper. Brush with egg wash and sprinkle with sesame seeds and salt.
Bake: Bake in a preheated oven at 400°F for 23 minutes. Increase the temperature to 500°F and bake for an additional 6 minutes to brown. Keep and eye on them when the heat is high!
Cool and Serve: Remove from the oven and let cool slightly before serving. Enjoy your warm, chewy, protein-packed pretzels!
