Combine warm water and yeast in a large bowl. Let it stand for about 5-10 minutes until it becomes foamy.

Mix in the bread flour, granulated sugar, kosher salt, dark brown sugar, beaten egg, and everything bagel seasoning. Stir until a dough forms.

Knead the dough on a floured surface for about 10 minutes.

Place the dough in a greased bowl, cover it with a damp cloth, and allow it to rise in a warm area for about 1 hour.

Preheat the oven to 425°F (220°C).

Punch down the risen dough and divide it into 12 equal pieces. Shape each piece into a bagel.

Boil a large pot of water. Gently drop in the bagels, boiling for 1-2 minutes on each side.

Remove the bagels and place them on a greased baking sheet. Brush each bagel with frothy egg white.

Bake in the preheated oven for 20-27 minutes until they turn golden brown.

Let cool slightly before serving.
