Pour a small amount of the chocolate mixture into the bottom of each liner or mold cavity, until the bottom is thinly covered. Swirl the chocolate around or use your fingers to spread it onto the sides of the liners too. Don't use more than half the chocolate mixture for this. Place the liners in the refrigerator for about 10 minutes to harden.
While the chocolate hardens, stir together the melted coconut butter, cashew butter, 2 tablespoons maple syrup, pumpkin puree, and pumpkin spice.
