Combine 1 cup rolled oats, 1 scoop vanilla protein powder, 2 tablespoons ground flaxseed, 1 teaspoon ground cinnamon, and a pinch of salt in a large mixing bowl.

Add ½ cup natural peanut butter, ¼ cup honey (or maple syrup), and 1 teaspoon pure vanilla extract to the dry mixture.

Gradually incorporate almond milk, one tablespoon at a time, until the mixture holds together.

Roll the mixture into 1-inch balls and place on a parchment-lined tray.

Chill in the refrigerator for at least 15-20 minutes.

Transfer to an airtight container and store in the fridge for up to a week or freeze.
