Step 1

To make the starter: Weigh your flour; or measure it by gently spooning it into a cup, then sweeping off any excess.

Step 2

, In a large bowl or the bowl of your stand mixer, stir together the starter ingredients to make a shaggy dough, then use your hand to knead gently until thoroughly combined. (This may take about a minute; it's quite stiff.) Cover the bowl and let the starter rest at room temperature for 4 to 14 hours; it should expand.

Step 3

, To make the dough: Add the remaining dough ingredients in the order listed to the bowl with the starter, except the Cinnamon Sweet Bits. Mix to bring the dough together, by hand or at low speed of a stand mixer with the dough hook attachment. Next, knead the stiff dough until it’s supple and elastic. This will take up to 15 minutes by hand or 8 to 10 minutes at medium-low speed with a mixer.

Step 4

, Add the Cinnamon Sweet Bits during the last 2 minutes of kneading.

Step 5

, Place the dough in a lightly greased bowl and let it rest, covered, until it doubles in bulk. This will take about 2 to 2 1/2 hours depending on the warmth of your kitchen.

Step 6

, Turn the dough out onto a clean surface, gently deflate it, and divide it into 6 equal pieces (about 120g each).

Step 7

, To pre-shape the dough: Working with one piece of dough at a time, fold the edges into the center. Pinch to seal and set aside. Repeat with the remaining pieces of dough.

Step 8

, Starting with the first piece of dough you shaped, place it seam-side down on an unfloured surface. Use your cupped fingers and palm to roll the dough into a tight ball, moving your hand in a circular motion. The dough should stick slightly to the surface in order to create tension to yield a smooth exterior. If the dough is unmanageably sticky, add a very light dusting of flour; if the dough slides around on the surface without tightening, use a damp towel to clean and moisten the surface and try again.

Step 9

, Once shaped into a tight ball, place the dough onto a lightly floured surface and repeat with the remaining pieces of dough.

Step 10

, Cover the pre-shaped dough and allow it to rest for 10 to 15 minutes.

Step 11

, Line a baking sheet with parchment and lightly grease the parchment; or sprinkle the parchment lightly with cornmeal, semolina, or farina, to prevent the bagels from sticking.

Step 12

, To shape the bagels: Working with one piece of dough at a time, use your finger to poke a hole through the center. Gently rotate the dough to expand the hole to 2” to 3” in diameter, forming a ring shape. Place the shaped bagel onto the prepared baking sheet. The hole will close up a bit; that’s OK.

Step 13

, Repeat with the remaining pieces of dough, then cover the bagels with a reusable cover or lightly greased plastic wrap and let them rest until they feel slightly puffy to the touch, about 30 minutes.

Step 14

, While the bagels are resting, preheat the oven to 450°F.

Step 15

, To make the topping: In a small bowl, whisk the sugars, flour, and cinnamon together. Add the vanilla and melted butter and stir until the mixture resembles wet sand.

Step 16

, To boil the bagels: Combine the water bath ingredients in a wide, shallow pot; the water should be at least 1 1/4" deep. Bring the mixture to a boil. Add bagels to the water two or three at a time to avoid crowding. Boil for 60 seconds, then use a dough whisk or slotted spoon to turn the bagels over. Boil for another 60 seconds before removing from the water and placing on the prepared pan.

Step 17

, Brush each bagel with egg wash and sprinkle with the topping, distributing evenly across the 6 bagels. For even more cinnamon crunch, sprinkle the tops of the bagels with more Cinnamon Sweet Bits and/or sparkling sugar. Press down on the toppings to fully adhere them to the bagel, ensuring that everything stays put.

Step 18

, Bake the bagels for 18 to 22 minutes, until golden brown. Rotate the pan (front to back, back to front) halfway through baking to ensure even browning. If at any point the topping is becoming too dark, tent with foil and continue baking.

Step 19

, Remove the bagels from the oven and transfer them to a rack to cool.

Step 20

, Storage information : These bagels are best enjoyed the day they’re made. Store any leftover bagels in a paper bag for up to 2 days; freezing is not recommended, as the sugary topping will become sticky upon thawing. To re-crisp, bagels can be toasted or wrapped loosely in foil and placed in a 350°F oven until warm.
