Use rolled oats for best texture; quick oats get too soft and steel-cut oats won’t soften enough. Chill mixture before rolling to avoid sticky hands. Natural peanut butter with some oil separation works fine if stirred first. Adjust sweetener if swapping honey for maple syrup or agave. Optional add-ins include chopped nuts, dried fruit, shredded coconut, chia or hemp seeds, cinnamon, or protein powder.
