Preheat the oven to 375 degrees Fahrenheit and line a baking sheet with parchment paper.

Transfer the flour, sea salt, one cup Greek yogurt, sugar (if adding) and cinnamon (if adding) to a stand mixer fitted with the paddle attachment.

Mix on medium speed to combine the ingredients. Once the ingredients are combined and a crumbly mixture results, increase the speed to medium-high speed and continue mixing until a thick dough forms (about 2-3 minutes). If adding dried blueberries, do so now, and continue mixing until the dried blueberries are well-distributed throughout the dough.

Form a ball out of the dough, then section it into 4 equal portions. Take each portion, roll into a ball, then form a bagel shape out of each portion with a hole in the center.

Transfer the raw bagels to the prepared baking sheet and bake for 22-25 minutes at 375 degrees F. Increase the heat to 450 and bake for another 3-5 minutes, or until the tops of the bagels are golden brown.

Allow the bagels to cool for at least 10 minutes before serving.

Using a bread knife to slice a bagel in half, toast it in the toaster or toaster oven and spread with butter, cream cheese, cinnamon sugar blend, or your favorite topping. Enjoy!
