Prep this creamy, protein-packed overnight oat jar in just 5 minutes the night before and wake up to a ready-made breakfast. No cooking required.
Use rolled oats, not quick or instant oats, for the best texture. A ripe banana with brown spots gives the most sweetness. If your protein powder is already sweetened, taste before adding honey or syrup. Oats keep in the fridge for up to 5 days in a sealed jar. Add toppings like fresh fruit, granola, or nut butter right before serving to keep them fresh.
