Combine the pumpkin puree, almond butter, maple syrup, and pumpkin pie spice in a large bowl and stir until smooth.
Fold in the rolled oats, pepitas, raisins, and chia seeds. Cover the bowl with plastic wrap and refrigerate for about 2 hours, or until the mixture is chilled and easy to work with.
Roll the mixture into balls. (If you have a small cookie dough scoop, that works perfectly!) Store the balls in the refrigerator or freeze and thaw for a few minutes before eating.
