Preheat the oven to 400°F. Stuff each date with 2 tablespoons cheese, wrap half a bacon slice around the stuffed date, and skewer with a toothpick to secure.
Rub each wrapped date with a teaspoon of sugar, arrange on a baking sheet, and bake, turning once, until bacon is crisped and the date is caramelized, 10–12 minutes total.
