These creamy high-protein peanut butter overnight oats are a no-cook, meal-prep-friendly breakfast that tastes like peanut butter pudding. With 20 grams of protein per serving, they keep you full until lunch without the mid-morning crash.

Ingredients

Scale
  • 1/2 cup rolled oats (45g)
  • 1/3 cup milk of choice (80ml)
  • 1/4 cup plain Greek yogurt (60g)
  • 2 tablespoons natural peanut butter (32g)
  • 1 tablespoon honey or maple syrup (15ml)
  • 1 tablespoon chia seeds (12g, optional)
  • 1/2 teaspoon vanilla extract
  • Pinch of salt

Instructions

  1. Combine the wet ingredients: In a medium bowl or directly in your mason jar, whisk together 1/3 cup milk, 1/4 cup Greek yogurt, 2 tablespoons peanut butter, 1 tablespoon honey, and 1/2 teaspoon vanilla extract. Whisk until the peanut butter is fully incorporated—no streaks allowed. If your peanut butter is stubborn, microwave the mixture for 15 seconds to soften it.
  2. Add the dry ingredients: Stir in 1/2 cup rolled oats, 1 tablespoon chia seeds (if using), and a pinch of salt. Mix until everything is evenly distributed. The mixture will look a little thin at this point—that’s normal. The oats and chia will absorb the liquid overnight.
  3. Transfer to jars: Divide the mixture evenly between two 16-ounce mason jars or one larger container. Leave about an inch of headspace at the top for toppings or expansion. If you’re using one container, just pour it all in.
  4. Seal and refrigerate: Screw the lids on tightly and place the jars in the refrigerator. Let them sit for at least 6 hours, but overnight (8-12 hours) is ideal. The longer they sit, the thicker they get.
  5. Add toppings and serve: In the morning, take a jar out of the fridge. Give it a good stir—the chia seeds sometimes settle at the bottom. If the oats are too thick for your liking, stir in a splash of milk. Top with sliced banana, a drizzle of peanut butter, chocolate chips, or crushed peanuts. Eat cold or let it sit at room temperature for 10 minutes if you prefer less chill.

Notes

For best results, use rolled oats (not quick or steel-cut). Mix peanut butter thoroughly into wet ingredients before adding oats. Let oats sit at least 6 hours, ideally 8-12. Oats keep in fridge up to 5 days; add toppings fresh. If too thick, stir in a splash of milk. For vegan version, use plant-based milk and yogurt, and maple syrup instead of honey.
