Preheat Oven : Set oven to 350°F (175°C) and line a baking sheet with parchment or silicone mat.

Prepare Maple Mixture : In a large bowl, whisk together maple syrup, melted butter, sugar, cinnamon, salt, and vanilla extract until smooth.

Coat Pecans : Add pecans to the bowl and toss until every nut is evenly coated in the maple mixture.

Arrange on Baking Sheet : Spread the pecans in a single layer to ensure even baking.

Bake : Place in oven and bake for 15–20 minutes. Stir halfway to prevent burning and ensure all nuts caramelize evenly.

Cool : Remove from oven and allow to cool completely on the baking sheet. The pecans will harden as they cool.

Serve or Store : Once cooled, transfer to an airtight container or serve immediately.
