Preheat the oven to 325°F (165°C) and line an 8-inch square pan.
Mix graham crumbs, butter, and 1/4 cup sugar.
Press the mixture firmly into the pan and bake for 8 minutes.
Beat the cream cheese and remaining sugar until smooth.
Add pumpkin, eggs, vanilla, cinnamon, and pumpkin pie spice.
Pour the filling over the crust and smooth the top.
Bake for 35–40 minutes until the center is nearly set.
