1. 1. In a large mixing bowl, combine the warm water, yeast, and 2 tablespoon of sugar. Allow this mixture to sit for 5-10 minutes, until it becomes foamy and bubbly.

2. 2. Once the yeast is activated, add the mashed bananas, chopped walnuts, salt, bread flour, and cinnamon to the bowl. Mix everything together until a cohesive dough forms.

3. 3. Turn the dough out onto a lightly floured surface and knead it for 8-10 minutes, until it becomes smooth and elastic.

4. 4. Place the kneaded dough in a greased bowl, cover it, and let it rise for about an hour, or until it has doubled in size.

5. 5. Divide the dough into 8 equal pieces and shape each one into a round ball. Using your fingers, poke a hole in the center of each ball to create the classic bagel shape.

6. 6. Bring a large pot of water with 3 tablespoon of sugar to a boil. Gently drop the shaped bagels into the boiling water and let them cook for 1-2 minutes per side.

7. 7. After boiling, place the bagels on a baking sheet. Beat an egg with 1 tablespoon of water and brush the tops of the bagels with the egg wash. Bake the bagels at 425°F for 20-25 minutes, or until they’re golden brown and irresistibly delicious.

8. 8. Once the Banana Nut Bagels have baked to perfection, let them cool completely before serving.
