In a medium mixing bowl, combine softened cream cheese, shredded cheddar cheese, crumbled cooked bacon, mayonnaise, sour cream, a dash of hot sauce, and salt and pepper to taste. Mix until smooth and creamy. Cover and refrigerate for about 30 minutes.

Preheat your oven to 190°C (375°F). Slice a thin layer off the bottom of the bagels to create a flat base and hollow out the center carefully.

Stuff each hollowed bagel generously with the cream cheese filling using a spatula, smoothing the tops evenly.

Arrange the filled bagels on a parchment-lined baking tray. Bake for 12-15 minutes, or until tops are golden and filling is bubbling.

Remove from the oven, cool slightly, and garnish with reserved crumbled bacon and fresh chives before serving.
