Preheat oven to 350 F and prepare a 7 or 8-inch cheesecake pan by lightly greasing it with butter.
Grind the pecans + graham crackers, until almost finely ground. Combine the pecan-graham cracker mixture, 3 tablespoons organic brown sugar, 1 teaspoon cinnamon and 4-5 tablespoons of melted butter in a small bowl and mix with a spatula until well incorporated.
Add the mixture into the prepared pan and press down into the bottom with your fingers to ensure that it’s perfectly covering the bottom and sides.
Bake the crust for about 5 minutes and then remove from oven and allow it to cool until you’re ready to use.
In the bowl of an electric mixer, mix together on low speed: 16 ounces cream cheese, ¾ cup organic pure cane sugar, and 4 tablespoons flour until combined.
Add 2 teaspoons vanilla extract and the first egg and beat slowly until mostly combined. Then add the remaining egg and mix until well combined, still mixing everything on low speed.
Now, slowly whisk in ¼ cup heavy whipping cream and continue stirring until well incorporated and sauce has fully thickened. Remove from heat and allow to cool slightly before using.
Pour the batter into the prepared pan until ¾ filled. Leave a bit of room at the top to prevent the cheesecake from spilling over while baking.
Bake the cheesecake for 35-40 minutes, then turn off the oven and allow it to sit in the oven for another 5 minutes with the oven door halfway open.
Remove cheesecake from the oven and allow it to continue to cool for another 15-20 minutes, before putting it in the refrigerator for at least an hour.
In a large skillet of medium-high heat, add 3 tablespoons butter and heat until melted. Add brown sugar, cinnamon, ground ginger, ground nutmeg, ground cardamom, ground allspice, and sea salt and stir until well combined.
Add the apples and toss until well coated and cook for 8-10 minutes, until tender and the sauce has thickened.
Once cheesecake has fully chilled, top with warm caramelized apple spice topping, slice and enjoy.
