  • Total Time: 5 minutes active + overnight soak
  • Yield: 1 serving

Ingredients

1/2 cup old-fashioned rolled oats (gluten-free if needed)

1/2 cup milk (almond, oat, cashew, or dairy)

1/2 cup Greek yogurt or non-dairy yogurt

1 scoop vanilla or unflavored protein powder

1 tbsp chia seeds

1/2 tsp vanilla extract

Optional add-ins: mashed banana, diced apple, cinnamon, nut butter, coconut, berries, maple syrup

Instructions

  1. In a mason jar or container, combine oats, milk, yogurt, protein powder, chia seeds, and vanilla extract.
  2. Stir well to ensure oats are fully submerged. Add a splash more milk if mixture is too thick.
  3. Mix in desired flavor add-ins such as banana, nut butter, or berries.
  4. Seal the container and refrigerate for at least 6 hours or overnight.
  5. In the morning, stir well. Add a splash of milk if needed and top with additional fruit or nut butter.
  6. Enjoy cold or microwave for 30–60 seconds if a warm breakfast is preferred.

Notes

  • Use old-fashioned rolled oats for best texture. Avoid steel-cut oats.
  • Choose any protein powder—whey, pea, or plant-based all work well.
  • Make it dairy-free by using plant-based milk and yogurt.
  • Great for meal prep—store in the fridge for up to 5 days or freeze for 1 month.
  • Warm up in the microwave if desired. Stir and add milk before heating.
