In a medium bowl mix with a fork the flour, oats, sugar and cold butter together. Mix until it's crumbly.
Press evenly into your greased pan. I placed mine on a cookie sheet to stabilize the silicone form. Bake in a pre-heated 350 F for 20 minutes.
While the crust is baking In a large bowl mix together pumpkin, milk, sugar, cinnamon, ginger, cloves, and salt. Beat until blended.
Pour over your baked crust.
Return to the oven for about 30 - 40 minutes, or until a knife inserted in the center comes out clean.
Cut into serving-size pieces and enjoy.
