Preheat the oven to 350 degrees. Line an 8x8 glass baking dish with parchment paper.
For the crust, combine all the dry ingredients in a large mixing bowl, then stir. Next add all the wet ingredients and stir until thoroughly well.
Pour the dough into the baking dish and pat down until it’s evenly spread out at the bottom of the pan.
Place the baking dish in the oven for 20 minutes. When it’s finished cooking, let sit until cool.
While the crust is cooling, prepare the filling. Combine all the ingredients except the gelatin in a saucepan. Stir to combine. Warm the pumpkin mixture over medium heat while stirring occasionally. Once the pumpkin mixture has warmed, sprinkle the gelatin over the top and stir to combine.
Once combined remove from the heat and pour into the baking dish. Put the baking dish into the fridge for at least 4 hours but overnight is ideal.
When the pumpkin has cooled and set, then it’s ready to serve.
