In a food processor fitted with the blade attachment, combine the drained dates, pecans, and salt. Process until combined and the “dough” starts to form into a ball.
In a separate bowl, combine the pumpkin purée, coconut milk, pumpkin pie spice, maple syrup, salt, and collagen peptides. Whisk until smooth.
Line a cupcake tin with paper or silicone cupcake liners and evenly distribute the crust mixture, about 1½ tablespoons, into each crevice. Use your fingers to press the crust to an even layer.
Evenly disperse the pumpkin pie mixture between each crevice, until about half full.
Top each with a pecan and freeze for at least 1 hour.
