To Make Keto Pumpkin Cheesecake Pie Crust:
The next day, start by pulsing almonds and pumpkin seeds in food processor until ground into small pieces.
Add remaining crust ingredients and pulse together, until a sticky dough forms.
Scoop ~1 tsp of dough into base of each silicone mold, depending on size, pressing to flatten. (Aim for a crust layer around ⅛- to ¼-inch thick.)
Transfer molds to the fridge for 20-30 minutes to set while you make the filling.
