Step 1 — Make the Crust : Preheat oven to 325°F / 160°C. Mix graham crumbs, pecans, sugar, and melted butter. Press firmly into bottom of a 9-inch springform pan. Bake 10 minutes; set aside to cool.
Step 2 — Prepare the Maple Filling : Beat cream cheese until smooth (avoid air bubbles). Add brown sugar; blend well. Mix in sour cream, maple syrup, vanilla, cinnamon, and salt. Add cornstarch; combine fully. Add eggs one by one—mix on low speed to prevent cracking. Pour evenly over the crust.
Step 3 — Bake : Set pan in a water bath (optional but prevents cracks). Bake 55–65 minutes until edges are set but center is slightly jiggly. Turn off oven; crack the door open; let cheesecake rest 1 hour. Chill in fridge at least 4 hours or overnight.
Step 4 — Brown Sugar Glaze : Combine brown sugar, cream, and butter in a small saucepan. Heat until melted and glossy—don’t boil hard. Stir in maple extract. Cool 5 minutes, then pour over chilled cheesecake. Top with toasted pecans.
