Add the warm water, yeast, brown sugar, canola oil, and salt to the bowl of a stand mixer. Whisk together with a fork just to combine.
Add the flour to the bowl and mix on medium/low speed for 10 minutes. The dough should form a smooth ball. (See notes)
Grease a large bowl with butter or oil then add the dough and allow to rise for 1 hour.
While the dough is rising, you can pre-heat your oven to 400° and line 2 baking sheets with parchment paper or silicon mats. (You can also set your 6 cups of water to boil towards the end of the rise time as well)
After the dough has risen, you can place it on your clean countertop. Divide it into smaller pieces (about 6 or 8) so it's easier to work with.
Take each piece of dough and roll it on the counter while stretching so you have about an 18" long piece. Cut the long piece into 1-2 inch bite-sized pieces.
Baking Soda Bath
Bring the 6 cups of water to a boil then add in the baking soda. Lower to a simmer.
In small batches, add the dough pieces to the simmering water for 30 seconds then remove with a slotted spoon and place on the prepared baking sheets. Leave at least 1 inch in between each piece.
Bake in the pre-heated oven for 15 minutes. if you are using more than one pan, be sure to swap the oven racks half way through.
Cinnamon Sugar Topping
Allow the pretzel pieces to cool for about 5-7 minutes then add them to a zip-top bag.
Pour the melted butter over the pretzels, close the bag, and shake to coat all of the pretzel bites.
In a small bowl, mix together the cinnamon and sugar then open the bag and add it to the pretzels. Seal the bag and shake again. Serve warm!
Store in an airtight container for about 3-4 days.
Notes
When making the dough If it seems dry and won't form a ball, you can add 2 more tablespoons of water until it smooths out. If your dough seems too sticky, add 2 tablespoons of flour. Adjust as needed.
