Step 1

Make crust: Preheat oven to 375 degrees. In a food processor, pulse graham crackers until finely ground (you should have about 2 1/4 cups). Add 1/4 cup granulated sugar, 1 stick melted butter, and 1/4 teaspoon salt and pulse until combined. Firmly press mixture into bottom of a 9-by-13-inch baking dish. Bake until crust is dry and set, about 12 minutes. Remove from oven and reduce temperature to 325 degrees. Let cool completely.

Step 2

Make topping: Combine butter, flour, brown sugar, a pinch of salt, and pecans in a bowl. Rub butter in with your fingers until mixture is well combined and crumbly. Set aside.

Step 3

Make filling: Pulse cream cheese in food processor until smooth. Add 3/4 cup granulated sugar and pumpkin and process until smooth, occasionally scraping down sides of bowl. Add eggs, flour, 1/2 teaspoon salt, cinnamon, ginger, and cloves; process until incorporated. Pour filling into cooled crust, scatter crumbles of topping over and bake until custard is just set and puffed, about 50 minutes. Let cool completely on a wire rack. Cut into bite sized squares.
