1. 1. Combine the dry ingredients: In a medium-sized mixing bowl, add the rolled oats, ground flaxseed, and pumpkin pie spice. Use a spoon or whisk to mix these dry ingredients thoroughly until they are well combined. This ensures the spices are evenly distributed throughout the bites.

2. 2. Add the wet ingredients: To the same bowl, add the pumpkin puree, creamy peanut butter, maple syrup, and vanilla extract. These are the binding and flavoring agents for your energy bites.

3. 3. Mix everything together: Using a sturdy spoon or a rubber spatula, mix all the ingredients until a thick, uniform dough forms. It might take a few minutes to get everything fully incorporated, especially the peanut butter. Keep mixing until there are no dry spots and the mixture holds together when pressed.

4. 4. Fold in chocolate chips (optional): If you’re adding mini chocolate chips, gently fold them into the mixture now. Distribute them evenly so each bite gets a little chocolatey goodness.

5. 5. Chill the mixture: Cover the bowl with plastic wrap and place it in the refrigerator for at least 20 minutes. This chilling step is crucial as it allows the oats to absorb some moisture, making the mixture firmer and much easier to roll into balls without sticking to your hands.

6. 6. Roll into bites: Once chilled, remove the mixture from the refrigerator. Scoop out about 1 tablespoon of the mixture at a time and roll it between your palms to form small, uniform balls, roughly 1 to 1.5 inches in diameter. If the mixture is still a bit sticky, you can lightly dampen your hands with water.

7. 7. Arrange and serve: Place the finished energy bites on a plate or in an airtight container. They are ready to enjoy immediately, but they firm up even more after a little longer in the fridge.
