Healthy and easy overnight oats that taste like oatmeal cookies? Yes, please! I've been making this Oatmeal Cookie Overnight Oats recipe for YEARS and it's one of my hands-down favorite healthy breakfasts! They're mixed together in just 5 minutes, stored in the fridge overnight, and they're ready to go in the morning. These easy overnight oats are the best for busy weekday breakfasts that the entire family will love!
