Chocolate Peanut Butter Overnight Oats Recipe

These overnight oats are a weekday staple at my house. They’re cool and creamy, and taste like the breakfast version of a Reese’s peanut butter cup. I typically double the batch so that I have some on hand for breakfast, and some to dig into for dessert. They just have a way of satisfying the sweet tooth unlike anything else.

These overnight oats are also super adaptable. Some mornings, I’ll mix in a couple Tablespoons of my favorite protein powder for extra staying powder. Other times, I add a spoonful of hemp seeds or mashed banana for added sweetness. That’s the best part of overnight oats: No two servings ever have to be the same.

What is the Ratio for Overnight Oats?

The best starting ratio for overnight oats is 1 cup of liquid for every 1 cup of oats. The caveat, however, is if you add other dry ingredients to the mix. For example, this recipe calls for cocoa powder and (optional) protein powder, which will require more liquid for soaking. Sometimes yogurt can negate the need for extra liquid, however most times you’ll need an extra 2 to 4 Tablespoons of milk/liquid.

If you like your overnight oats really thick, definitely start with the 1:1 ratio. However, if they’re TOO thick the next morning, you can always mix in extra milk as needed. No need to perfect the recipe the night before.Ingredients for Overnight Oats in a JarChocolate Peanut Butter Cup Overnight Oats Recipe

Overnight Oats with Greek Yogurt

Adding yogurt is a game-changer for overnight oats. It creates a thick, creamy consistency, plus adds protein and probiotics. I typically add 1/4 cup Greek yogurt for every 1 cup of oats. Don’t be afraid to use whole-milk varieties of yogurt here–they add extra staying power, plus help you better absorb the fat-soluble vitamins.

My favorite brands to use are Siggi’s (not Greek yogurt, but similar in texture) and Fage. Also, feel free to go for a flavored variety–I typically stick with vanilla, however the fruit flavors are always fun to switch it up.

What to Add to Overnight Oatmeal:

  • Old-fashioned Rolled Oats: These are a MUST. I do not suggest quick-cooking or steel cut oats for overnight soaking. Quick-cooking will become too mushy, and steel-cut won’t soften nearly enough.
  • Milk: I love using an alternative milk such as almond, cashew, or oat milk. They’re thicker than dairy milk, which leads to a creamier consistency.
  • Natural Peanut Butter: It’s important to use natural here because it mixes better. My personal favorites in terms of taste and consistency are Trader Joe’s and Whole Foods 365 brands.
  • Seeds: Chia, flax, and hemp seeds are totally optional, however they add a big nutritional boost (omega-3 fatty acids and protein). If you do add seeds, stick to 1 Tbsp for every 1 cup of oats, and increase the milk by 1/4 cup.
  • Protein Powder: Also optional, however it does give the oats more staying power. My personal favorite protein powder is Bob’s Red Mill–It contains chia and probiotics, and is likely sweetened with monk fruit.
  • Maple Syrup: This is the BEST sweetener for overnight oats because it mixes well, and a little goes a long way. Plus, the flavor profile bodes well for just about any breakfast combination.

Do you Eat Overnight Oats Hot or Cold?

Overnight oats are meant to be eaten cold, however, if you prefer them warm, you always have the option to heat them up. Because they soak overnight, they are plenty soft to enjoy cold right out of the refrigerator. I suggest just serving them alongside a hot mug of coffee so you have the best of both worlds.Overnight Oats with Greek Yogurt, Peanut Butter, and Chocolate
