To make the crust, in a food processor, pulse the graham crackers and pecans until fine crumbs. Add brown sugar, cinnamon and melted butter and pulse until combined. Press the mixture evenly onto the bottom and slightly up the sides of an ungreased 9-inch spring form pan. Refrigerate while preparing the filling.

Preheat the oven to 350°F (175°C).

To make the filling, in the large mixing bowl with paddle attachment, beat the cream cheese until fluffy on medium speed, about a minute. (Or you can also use electric hand mixer.) Add sugar and maple syrup and continue to beat for another minute. Stir in the pumpkin puree, vanilla extract, ground cinnamon, nutmeg and salt. Mix until well combined, about 1 minute, scraping the sides half way. Beat in the eggs one at a time and mix just until combined on low speed. (Don’t beat the mixture too long and too fast after you add the eggs. Otherwise too much air will incorporate to the batter, which might cause a crack in the cooked cheesecake.) Pour the batter into the prepared crust.

Bake for 50-60 minutes, or until the edges of the cheesecake is set, but the center is slightly wobbly. Cool on a wire rack for 5 minutes. Carefully run a knife around edge of the pan to loosen; cool for another hour. Then refrigerate for at least an hour to cool completely.

To make the frosting beat the whipped cream in a mixing bowl with whisk attachment, until hard peaks form. Add pumpkin puree and maple syrup and mix until smooth.

Once the cheesecake is completely cooled, remove springform sides of the pan. Spread the frosting evenly and serve.
