Pro Tips: Use rolled oats for the best chewy texture. This recipe is endlessly customizable – make it dairy-free, gluten-free, nut-free, or boost the protein with a scoop of vanilla protein powder. For an even more authentic cookie dough flavor, use brown sugar instead of maple syrup. If the oats are too thick in the morning, just stir in a splash of milk. Store in the fridge for up to 5 days for easy weekly meal prep.
