Recipe Ingredients

WET

  • Banana: Use a fairly ripe banana so you get some natural sweetness. The peel should have some black, do not use a green banana. 
  • Peanut butter: Smooth peanut butter works best. Choose one that is just peanuts without added sugar. 
  • Greek yogurt: Use non-fat plain Greek yogurt, dairy or non-dairy will both work.
  • Almond milk: Unsweetened almond milk adds moisture.
  • Honey:  For a touch of natural sweetness, add as much or as little as you like. 
  • Vanilla extract: Add real vanilla extract for even more sweetness.

DRY

  • Rolled oats: Use old-fashioned oats for the best texture. 
  • Chia seeds: These tiny seeds are a great source of omega-3 fatty acids, fiber, and protein and help to thicken up the oats, both white or black chia seeds will work.
  • Cinnamon: Cinnamon adds warmth.

Variations

  • Swap the Peanut Butter: If you aren’t a fan of peanut butter you can use any nut or seed butter you like. 
  • Add some Crunch: Top your overnight oats with chopped nuts, or seeds to add more texture. 
  • Up the Protein: For even more staying power, mix in a tablespoon of your favorite protein powder; plain or vanilla would both work well. 

How To Make Overnight Oats With Peanut Butter and Banana

Step 1:  Place half of a banana in a bowl and mash. Then add peanut butter, Greek yogurt, almond milk, honey, and vanilla and mix well until combined.

Step 2: Stir in the rolled oats, chia seeds, and cinnamon. Mix well. Let the mixture sit for 5 minutes, then remix. 

All ingredients added to a bowl and combined.

Step 3: Cover and place in the refrigerator for 4 hours, or overnight.

Step 4: To serve, add the overnight oats to jars and then top with the remaining banana, sliced, a drizzle of peanut butter, and a sprinkle of oats for garnish before serving.

Tips

  • Fresh Peanut Butter: It is easier to blend the oats if you have fresh, smooth, pourable peanut butter. If your peanut butter has hardened somewhat pop it in the microwave to soften. 
  • Save your Bananas: No banana should ever go to waste. Once they ripen, peel and throw in the freezer. This way you can pull them out as you need them to add to oats, smoothies, or to make banana bread. 
  • Make a Double Batch – If you want to have a quick and easy go-to breakfast for a few days, go ahead and double or triple the recipe. 
  • Adjust the Amount of Milk – Feel free to add more milk if you like your overnight oats more watery.

FAQs for Overnight Oats

How long do overnight oats last?

Overnight oats can last up to 5 days in the refrigerator. Note, that the banana may turn brown after it sits in the fridge for a few days. It will still taste ok. 

Can I double the recipe?

Yes, absolutely! If you want to make sure you’ve got a few day’s worth of breakfast in the fridge, double or triple the recipe.

Can I use a different type of milk?

Sure, if you don’t have unsweetened almond milk on hand you can use whatever you like. If you only have sweetened milk, adjust the amount of honey accordingly.

This recipe is not only great for breakfast, but it’s perfect to have in the fridge for a post-workout snack or healthy afternoon treat.
