Preheat the oven to 400ºF and lay a piece of parchment paper down onto a baking sheet. Set aside.

Next, pour yeast, water, and sugar into the bottom of your KitchenAid Stand Mixer's metal bowl. Gently stir mixture together (be careful not to over stir) and let sit until foam begins to form. This will take around 15-20 minutes.

While yeast is foaming, add all-purpose flour, whole wheat flour, salt, and butter to a medium bowl. Mix until combined.

Once yeast mixture is ready, place mixing bowl onto your KitchenAid Stand Mixer and attach the dough hook. Turn KitchenAid Stand Mixer to low and slowly add in 1/3 cup of the flour mixture at a time. Continue to mix until the dough has formed. Pretzel dough is ready when the dough is no longer sticky.*

Sprinkle a little flour onto a clean counter and create a ball with your dough. Cover dough with a tea towel and let sit for 10-15 minutes.

While dough is resting, add 1/3 cup baking soda and 8-9 cups of water into a large stock pot. Cover and bring to a boil.

After dough has rested, knead pretzel dough with your hands for 3-4 minutes and then separate your dough into 6 dough balls.

Take a dough ball and use both hands to evenly roll pretzel dough out into a 20-25 inch dough rope. Twist dough into a pretzel shape and pinch the ends so they do not fall apart in the water bath. Set aside.

When water has come to a boil, place one pretzel at a time into the boiling water for 15-20 seconds. Remove with a slotted spoon or spatula, shake access water from the pretzel, and place onto baking sheet lined.

Lastly, create an egg wash by whisking 2 large eggs in a small bowl. Then, wipe the top of each pretzel with the wash and sprinkle them with coarse sea salt.

Place pretzels in the oven and bake for 13-15 minutes.

Remove from oven and enjoy!
