Activate yeast (5 minutes).
In a stand mixer bowl, combine warm water and sugar. Stir in yeast and let sit until foamy.
Mix dough (10 minutes).
Add flour and salt. Using a dough hook, knead until a smooth dough ball forms. Gently fold in blueberries at the end.
First rise (60 minutes).
Cover with a damp towel and let rest in a warm spot until doubled in size.
Shape bagels (10 minutes).
Punch down dough. Divide into 8 equal pieces. Roll each into a ball, then poke a hole through the center with your finger and stretch into a ring.
Second rise (20 minutes).
Place shaped bagels on a baking sheet lined with parchment paper. Cover and let rest until slightly puffy.
Boil bagels (2 minutes each side).
Bring a pot of water to a boil, add sugar or honey, then gently lower bagels with a slotted spoon. Boil 1–2 minutes per side, then remove and drain.
Egg wash & bake (20–25 minutes).
Preheat oven to 425°F. Brush bagels with egg wash, then bake for 20 minutes or until golden brown.
Cool & serve.
Let cool on a wire rack for at least 10 minutes. Slice and enjoy with cream cheese!
