Add dough hook attachment to KitchenAid and mix flour, yeast, garlic powder and salt for 15-20 seconds, until mixed evenly. Next, add in melted butter and warm water, and mix on low for 2-3 minutes.
Increase speed to medium and mix for 3 more minutes.
Transfer dough to bowl and cover with plastic wrap. Let sit for 2-2.5 hours, or until dough has risen and doubled in size.
Break dough into 35- 40 small bite sized pieces.
Cook your sweetpotato. I like to microwave for 6-7 minutes, or until cooked. Once it cools, separate into 30-40 small circles to stuff in the dough.
Take your dough and press it around each little piece of sweetpotato, to create a sweetpotato stuffed dough bite.
Preheat oven to 400°
Line sweetpotato doughbites on baking sheet lined with parchment paper.
Mix 8 cups water and baking soda in large pot and bring to medium high heat. Heat until the baking soda is dissolved.
Using tongs or a largespoon, dip each sweetpotato pretzel bite into baking soda water mixture and hold for 20-25 seconds. Then transfer back to parchment lined baking sheet.
In a small bowl, mix egg with 1 tablespoon of water to form egg mixture.
Brush egg wash over each bite and then top with sea salt or coarse salt, to your taste.
Put baking sheets with bites in the oven and bake until the bites are golden brown, about 15 to 18 minutes.
Let cool at least 10 minutes and serve warm with mustard or marinara sauce, for dipping.
