The flavors of these oats are hearty, sweet, and loaded with tasty peanut butter. This is a breakfast that you can eat on-the-go and still feel full.

The full recipe is at the bottom of this page, but here’s an overview of the 6 ingredients you’ll need and the 2 steps to make them:

Peanut Butter Overnight Oats Ingredients:

Old-fashioned rolled oats:

Rolled oats work best for this recipe (avoid using quick oats)

Peanut butter:

Unsalted peanut butter is my go-to for this recipe but you can substitute any nut butter (almond, cashew, etc.)

Chia seeds:

Chia seeds are an important part of this recipe because they absorb liquid and help create the thick texture of overnight oats. If you leave out the chia seeds, compensate by using less milk in your oats.

Maple syrup:

For a little sweetness! You can substitute other natural sweeteners like honey or agave syrup. If you like your oats sweet, add a little more; and if you like your oats more savory add less.

Oat milk:

Oat milk is a perfect match for overnight oats! But this recipe is also tasty with any milk substitute (almond, cashew, soy or regular milk).

Cinnamon:

Cinnamon is the secret ingredient in this recipe – it’s adds just a hint of flavor that makes these oats SO satisfying and a little sweet 🙂

Popular Additions & Substitutions:

• Chocolate: add 1 teaspoon of cacao powder (or cocoa powder) to give these oats a chocolate twist and turn them into a decadent chocolate breakfast!
• Bananas: a popular topping for these oats is sliced bananas. Bananas are a delicious addition to the peanut butter flavor of this recipe.

Step 1: Mix Your Oats

Stir all of the ingredients together in a small mixing bowl or jar. This recipe makes enough for 1 serving of oats. If you’d like to make more servings, the conversions to make more are in the next section.

Step 2: Refrigerate

Let your oats sit in the fridge for at least 4 hours and preferably overnight. As the oats sit they will soften and absorb the liquid from the milk.
