Mix the dry base. In a large bowl, combine oats, flaxseed/chia, pumpkin pie spice, extra cinnamon, salt, pepitas, and dried fruit.
Stir the wet ingredients. In a separate bowl, whisk almond butter, pumpkin purée, maple syrup, and vanilla until smooth and glossy.
Bring it together. Pour the wet mixture over the dry and fold with a spatula. If using chocolate chips, add them once the mixture has cooled slightly so they don't melt.
Adjust texture. If the mixture feels too wet, add 2–3 tablespoons more oats. Too dry? Add 1 tablespoon more maple or a splash of almond milk.
Chill briefly. Cover and refrigerate for 10–15 minutes. It firms up and rolls easier.
Roll into balls. Scoop about 1 heaping tablespoon per ball and roll between your palms. Aim for walnut-sized bites.
Optional upgrade. Roll in coconut, crushed grahams, or a pinch of cinnamon-sugar for a bakery finish.
Set and store. Place on a parchment-lined tray and refrigerate 30 minutes to set before transferring to an airtight container.
