Peanut Butter Banana Overnight Oats - A Creamy, Make-Ahead Breakfast

Prep Time 10 minutes
Total Time 10 minutes
Servings 2 servings

Ingredients

  • Old-fashioned rolled oats (not instant or steel-cut)
  • Milk of choice (dairy, almond, oat, soy, or coconut)
  • Plain Greek yogurt (optional, for extra creaminess and protein)
  • Natural peanut butter (creamy or crunchy)
  • Banana (ripe, with some brown spots for sweetness)
  • Chia seeds (optional, for thickness and omega-3s)
  • Maple syrup or honey (optional, to taste)
  • Vanilla extract (optional, for flavor)
  • Salt (a small pinch to balance flavors)
  • Toppings (sliced banana, peanuts, cacao nibs, cinnamon, or a drizzle of peanut butter)

Instructions

  • Mash the banana: In a bowl or jar, mash a ripe banana until mostly smooth. Some small chunks are fine.
  • Whisk in wet ingredients: Add 1/2–3/4 cup milk, 1–2 tablespoons peanut butter, 1–2 teaspoons maple syrup or honey (optional), 1/2 teaspoon vanilla (optional), and a small pinch of salt. Whisk until the peanut butter is well incorporated.
  • Add the dry ingredients: Stir in 1/2 cup rolled oats and 1 teaspoon chia seeds (optional). If using Greek yogurt, add 1/4 cup now for extra creaminess.
  • Adjust thickness: The mixture should look pourable but not watery. If it’s very thick, add a splash more milk. If it’s thin, a bit more oats or chia will help.
  • Chill: Cover the jar or bowl and refrigerate at least 4 hours, but overnight is best for full hydration and creaminess.
  • Stir and top: In the morning, give it a good stir. Add sliced banana, a drizzle of peanut butter, chopped peanuts, cinnamon, or cacao nibs.
  • Serve: Enjoy cold straight from the fridge, or warm gently in the microwave with a splash of milk if you prefer it cozy.
