If the dates are dry or hard, let soak in hot water for 10 minutes, then drain and pat dry. Transfer the dates to a food processor fitted with a steel blade. Pulse until the dates are in small pieces and form a sticky ball.
Add the oats, pecans, pumpkin, 1 tablespoon maple syrup, chia seeds, pumpkin pie spice, vanilla extract, maple extract (if using), and salt. Pulse to combine. The oats and nuts should be in small pieces of roughly the same size, but not completely smooth. Taste and add 1-3 teaspoons additional maple syrup if you desire a sweeter mixture.
Transfer the mixture to a bowl, then cover and refrigerate for at least 30 minutes. With a spoon or cookie scoop, scoop the mixture then roll it into balls. Transfer to an airtight container and store in the refrigerator for up to 2 weeks or freeze for up to 2 months. If the balls are frozen, there is no need to let thaw—just eat immediately, or let them sit a few minutes to warm up if desired.
These Pumpkin Energy Balls can be kept in the refrigerator for up to 2 weeks or frozen for up to 2 months. You can eat the balls immediately from the freezer, or let them warm up a bit if you prefer.
