In a food processor, process the cookies along with the cinnamon. Then, pour these crumbs into a mixing bowl and add the melted butter to the mixture, until you have a gritty mass to play with.

If you want it to be firmer add more butter or a splash of water. But, be careful with the water, you don't want this to end up being gummy.

Grease your springform pan or line it with parchment paper, and put the crumb mixture on the bottom. Next, press it carefully using your fingers until it's firm. Then, refrigerate for ten minutes.

Meanwhile, preheat the oven to 200 degrees Celsius and place a water bath underneath the grill.

Wrap the springform pan with aluminum foil at the bottom so that the water from the bain-marie doesn't leak into the cheesecake.

First, prepare your electric mixer. Second, beat the cream cheese until smooth and creamy. Third, add the vanilla, sugar, and sour cream and mix until well combined.

Lastly, lower the speed and add the eggs one at a time. You can use a spatula to scrape the edges of the bowl so that everything blends well.

Pour your cheesecake mixture onto the crust and carefully tap it to eliminate any existing bubbles and prevent this from cracking.

Lower the temperature of the oven to 180 degrees Celsius and put Cheesecake in the water bath. Bake for about 1 hour.

Turn off the oven and leave the door semi-open. Let the cheesecake cool down inside the oven for another hour.

Once the time has passed, remove your cheesecake from the oven and let it cool to room temperate. Once is completely cool, refrigerate for at least 4 to 6 hours to let it sit correctly.

Melt the butter in a saucepan at low heat. Then, add the brown sugar and stir with a heatproof spatula. When it starts to bubble add the cinnamon, cream, and nuts. You can turn off the flame now.

Here's a tip: make sure you don't burn the butter, if this happens, your pecan pie topping will end up having a bitter taste.

Remove your cheesecake from the fridge, carefully lift the springform pan ring and pour the pecan pie mixture onto your cheesecake.
