Equipment

  • Mason jar or lidded container
  • Spoon
  • measuring cups & spoons
  • Refrigerator

Ingredients
  

  • 1/2 cup unsweetened almond milk (plain or vanilla)
  • 1/4 cup plain or vanilla Greek yogurt
  • 1/2 cup old-fashioned rolled oats
  • 1 scoop vanilla or unflavored protein powder (whey or pea)
  • 1/2 tbsp chia seeds
  • 1/2 tsp vanilla extract

Instructions
 

  • In a mason jar or container, combine almond milk, Greek yogurt, oats, protein powder, chia seeds, and vanilla extract.
  • Stir well until the oats are fully submerged; add a splash more milk if needed.
  • Add any desired flavor mix-ins—mashed banana, cinnamon, diced apple, peanut butter, pumpkin purée, etc.—and stir again.
  • Seal with a lid and refrigerate at least 6 hours or overnight.
  • In the morning, stir, thin with milk if desired, and top with fruit, nuts, or nut butter.

Notes

Use your favorite milk, protein powder, and toppings. The base keeps for up to 4 days in the fridge—perfect for Sunday meal prep. Thin with a splash of milk just before serving if you like a looser texture.
