Ingredients

  • 1 cup rolled oats
  • 1 tablespoon chia seeds optional
  • 1-2 tablespoons peanut butter
  • 1-2 tablespoons strawberry jam or any flavor
  • 1 cup plant-based milk

Optional Toppings

  • sliced bananas
  • chopped nuts
  • dried or fresh fruit
  • maple syrup
  • granola

Instructions

  • In a container, cup, or glass jar, layer the rolled oats, chia seeds (optional), peanut butter, and jam, in any order. If you want to get fancy, you can warm the peanut butter an drizzle it on the sides of the jar before adding the other ingredients. Pour the plant-based milk over the top. Do not mix. If desired, add any additional mix-ins you desire.
  • Cover and refrigerate overnight (or for 3+ hours).
  • Remove from fridge, top with any desired toppings, and enjoy!

Notes

  • Storage: Keep your overnight oats in an airtight container in the fridge for up to 5 days. Perfect for meal prep!
  • Thicker or Thinner Oats? If your oats are too thick in the morning, stir in a splash of plant-based milk to loosen them up. If they’re too thin, add a little more chia seeds or peanut butter and let them sit for 5-10 minutes.
  • Make It Warm: Prefer a cozy breakfast? Microwave your oats for 30-60 seconds, stirring halfway through.
  • Nut-Free Option: Swap peanut butter for sunflower seed butter or tahini for an allergy-friendly version.
  • Sweetness Adjustments: If you like it sweeter, stir in maple syrup, agave, or a mashed banana.
