Ingredients

• 2 cups old-fashioned rolled oats
• 2 cups plain nonfat Greek yogurt
• 1 1/2 cups unsweetened almond milk
• 2 scoops vanilla protein powder
• 2 medium crisp apples
• 1/4 cup natural peanut butter
• 2 tbsp chia seeds
• 2 tsp ground cinnamon
• 3 tbsp pure maple syrup
• 1 tsp vanilla extract
• 1 pinch of salt
• 1/4 cup chopped toasted walnuts

Instructions

1. 1Wash and core the apples, then dice them into small bite-size pieces so they soften overnight and distribute evenly.
2. 2In a large mixing bowl whisk together the Greek yogurt, almond milk, protein powder, maple syrup, vanilla, cinnamon, and salt until completely smooth with no powder lumps.
3. 3Stir in the rolled oats and chia seeds until every oat is coated and the mixture looks creamy.
4. 4Fold in most of the diced apple, reserving a small handful for topping in the morning.
5. 5Divide the mixture evenly among four lidded jars or meal-prep containers, packing it down gently.
6. 6Spoon a swirl of peanut butter on top of each jar and scatter the reserved apple pieces over the surface.
7. 7Seal the jars and refrigerate at least 6 hours or overnight so the oats hydrate and the flavors meld.
8. 8In the morning give each jar a quick stir; if it seems thick, loosen with a splash of almond milk.
9. 9Top with the chopped walnuts just before eating for crunch.
10. 10Serve cold straight from the jar for a grab-and-go school morning or warm gently in the microwave for 45–60 seconds if preferred.
