It doesn’t get much easier than a peanut butter overnight oats recipe! With about 5 minutes of prep, you can stir together a healthy, high protein breakfast or snack that will keep in the refrigerator for days. Make more than one at a time and you’ll be set for the week!

What are Overnight Oats?

Overnight oats are an alternative way to prepare oatmeal that doesn’t require any actual cooking! Rather than the traditional method of boiling oats, these raw oats are mixed with milk and Greek yogurt and refrigerated overnight. While chilling, the oats absorb the liquid, thicken, and soften so that they’re ready to enjoy in the morning!

Overnight Oats Ratio:

You can adapt this recipe to suit your taste preferences. I usually pick the fruit based on what’s in season or what’s available in my kitchen, but you can always start with the basic base recipe. The ratio for overnight oats is equal parts old-fashioned oats, Greek yogurt, and milk. Add sweetener and a dash of salt, to taste.

How to make Peanut Butter Overnight Oats with Yogurt and Milk:

These peanut butter banana fridge oats come together with just a handful of pantry staples.

Ingredients:

  • Old-Fashioned Oats
  • Plain Greek yogurt
  • Milk of choice
  • Honey
  • Peanut butter (or powdered peanut butter)
  • Vanilla extract
  • Salt
  • Banana

This is truly a simple process! First, stir together the oats, yogurt, milk, honey, peanut butter, vanilla extract and salt. Cover and refrigerate for at least 2 hours (or overnight).

When you’re ready to enjoy the overnight oats, stir in the sliced banana, add a splash of milk (if desired), and garnish with your favorite toppings!

How to serve Peanut Butter Overnight Oats:

I like to finish the oats with extra toppings! Here are a few tasty options:

  • Chocolate chips
  • Raisins or dried cranberries
  • An extra drizzle of honey or melted peanut butter
  • Chopped peanuts

Toppings for peanut butter overnight oatmeal

Do you eat overnight oats hot or cold?

Both! While the oats in this recipe are raw, the ingredients are safe to consume both cold or warm. In the summer, I love the refreshing taste of cool, creamy oats in the morning. If you can’t imagine eating cold oatmeal, you can gently warm the oats in a microwave-safe bowl in the microwave until they reach your desired temperature.

How long will peanut butter overnight oats last?

When sealed in an airtight container in the refrigerator, the oats will last for up to 5 days. Do not freeze the oatmeal — the yogurt will “break” when thawed and will have an odd texture.

Are overnight oats healthy?

Yes! This meal-in-a-jar is high in protein and healthy fats (thanks to the Greek yogurt and peanut butter), high in fiber, and full of whole grains. It will keep you satisfied and full all morning long — making it easier to control your appetite throughout the day. No more donuts in the snack room!

These peanut butter overnight oats are NOT Keto-friendly or low-carb, as they include 76 grams of carbohydrates per serving.

Cook’s Tips and Recipe Variations:

  • I use creamy Jif peanut butter (because that’s what we always have in our kitchen), but you can substitute with powdered peanut butter for a lower-calorie and lower-fat option, or you can use almond butter, cashew butter, or all natural PB.
  • Overnight Oats Jar Size: I love using mason jars or Weck jars for my oatmeal. The best size jar for this recipe is either the 16.9-ounce 1/2 liter tulip jar or the 1/2 liter mold jar . These jars give you plenty of room to stir the oatmeal and add toppings!
  • Which oatmeal for overnight oats? I only use old-fashioned (sometimes called “rolled”) oats for this recipe. These oats absorb the liquid in the jar, become soft and chewy, while still maintaining a bit of texture. I do not recommend substituting with quick oats or steel cut oats.
  • Keep the overnight oats ratio in mind, and feel free to multiply the ingredients using the same ratio to prepare more than one batch.
  • Prepare Chocolate Peanut Butter Overnight Oats by adding unsweetened cocoa powder to the liquid mixture, or add a handful of chocolate chips.
  • What yogurt for overnight oats? I used plain, non fat Greek yogurt, but you can substitute with any yogurt that you prefer. Vanilla would add a great touch of flavor and sweetness!
  • What milk for overnight oats? You can use any milk that you like. I used unsweetened vanilla almond milk here, but regular cow’s milk will also work.
  • There are about 489 calories in one serving of the oats. If you’re watching your fat intake or your calorie count, you can substitute with powdered peanut butter (or “peanut flour”) and you can use just half of a banana.
  • Instead of honey, try sweetening the oats with maple syrup or agave syrup. Adjust the amount of sweetener to suit your preferences. If you like sugar-free sweeteners, feel free to use those instead.
  • Prepare the oats in advance: This is a great “meal prep” option, since the oatmeal will stay fresh in an airtight container in your refrigerator for up to 5 days!
