Preheat the oven to 350°F (175°C). Line 8-inch square baking pan with aluminum foil, leaving two sides hanging over the edges.
In a medium bowl, combine the graham cracker crumbs and melted butter. Mix until the crumbs are evenly moistened with butter.
2/3 cup graham cracker crumbs, 3 tablespoons unsalted butter
Transfer the mixture into the prepared baking pan. Evenly spread it, lightly pressing into the pan. Chill in the refrigerator while preparing the filling.
In a large mixing bowl with paddle attachment, beat the cream cheese, sweetened condensed milk, maple syrup and sugar on medium high speed until creamy.
8 oz cream cheese, ½ cup sweetened condensed milk, 2 tablespoons pure maple syrup, 2 tablespoons granulated sugar
Add the egg, vanilla extract, and salt. Beat the mixture on medium speed until well combined, about 3 minutes.
1 large egg, 2 teaspoons pure vanilla extract, 1/8 teaspoon salt
Transfer half of the cream cheese mixture into a medium bowl.
Add pumpkin puree, cinnamon, and nutmeg into the mixing bowl with the remaining cream cheese mixture. Beat it on medium high speed until well combined.
½ cup pure pumpkin puree, ½ teaspoon ground cinnamon, ½ teaspoon freshly grated nutmeg
Using a large cookie scoop, spoon both mixtures in an alternating pattern into the prepared cookie crust. Swirl the two mixtures with a skewer. Tap on the counter a few times to release the bubbles.
Bake the cheesecake until it’s set on the edges and slightly wobbly in the center, for 25-28 minutes.
Cool the cheesecake to room temperature, then refrigerate for at least 2 hours. Cut into 16 squares, before serving. (TIP: For easy and clean cuts, run the knife under hot tap water to warm it up and wipe it clean with a damp paper towel in between slices.)
Store in the fridge, covered, for up to 5 days.
