In a mixing bowl, combine softened cream cheese, shredded cheddar, and cooled diced bacon. Add mayonnaise, sour cream, and hot sauce if desired, then season with salt and pepper. Mix until smooth and creamy.

Take your fresh bagels and carefully slice a thin piece off the bottom to create a flat base. Hollow out the center of each bagel, ensuring you leave enough bagel walls intact.

Evenly divide the creamy filling among the hollowed bagels, using a spatula or spoon to smooth the tops.

Preheat your oven to 190°C (375°F). Place the filled bagels on a baking tray lined with parchment paper and bake for 12-15 minutes until golden brown and bubbly.

Remove the bagels from the oven and let cool for a minute. Garnish with crispy bacon and chopped chives before serving.
