Equipment

  • Mason Jar
  • Mixing Spoon

Ingredients

Ingredients

  • 1/2 cup Rolled Oats Old-fashioned rolled oats, not instant
  • 1/2 cup Milk Dairy or plant-based, room temperature or chilled
  • 1/2 cup Greek Yogurt Plain or vanilla, room temperature for easier stirring
  • 1 tablespoon Chia Seeds For texture and omega-3s
  • 1 tablespoon Protein Powder Vanilla or chocolate, scoop leveled
  • 1 teaspoon Honey or Maple Syrup Optional for light sweetness
  • 1/4 teaspoon Vanilla Extract Good-quality extract for best flavor
  • 1/2 banana Banana Fresh, ripe, sliced
  • 1 tablespoon Nut Butter Optional, smooth or crunchy, warmed slightly for easy drizzling

Instructions

  • Choose a jar or airtight container that seals well — a standard 8-ounce mason jar works perfectly.
  • Add 1/2 cup rolled oats to the jar.
  • Pour in 1/2 cup milk, then add 1/2 cup Greek yogurt. Use a spoon to break up yogurt if needed so it mixes smoothly.
  • Sprinkle in 1 tablespoon chia seeds and 1 tablespoon protein powder. If using chocolate protein, expect a richer flavor; vanilla keeps it light.
  • Add 1 teaspoon honey or maple syrup if you like a touch of sweetness, followed by 1/4 teaspoon vanilla extract. Stir vigorously until all ingredients are evenly combined and no powdery clumps remain.
  • Press the sliced 1/2 banana into the top of the mixture and add 1 tablespoon nut butter on top if using. The banana will soften as it chills and sweeten the oats naturally.
  • Secure the lid and refrigerate overnight or for at least 6 hours. During this time, the oats and chia seeds absorb the liquid and create a thick, pudding-like texture.
  • In the morning, open the jar and give the oats a good stir. Add a splash of extra milk if you prefer a looser consistency. Top with fresh fruit, seeds, or a drizzle more of nut butter and enjoy cold or at room temperature.

Notes

Store in airtight jars or containers in the fridge for up to 4 days. The texture will continue to soften over time.
