Preheat oven to 350 degrees. Place cheese on a rimmed baking sheet; bake until softened, 15 to 20 minutes. Transfer to a serving plate; cool about 20 minutes.
While cheese cools, place nuts on a clean baking sheet; bake until toasted and fragrant, 7 to 10 minutes. Sprinkle nuts over cheese.
In a small saucepan, combine sugar and maple syrup. Bring to a boil over medium heat; simmer until foamy, 1 to 2 minutes. Drizzle warm sauce over slightly cooled cheese and nuts; serve with crackers or baguette.
