These simple PB2 (powdered peanut butter) Overnight Oats are made with oats and milk and then layered between sweet ribbons of fruity jam. It's a decadent but protein-packed breakfast!

My husband has been on a peanut butter binge lately. He puts peanut butter on peanut butter, and I have a front-row seat to the show.
Luckily, I don't mind it, because he introduced me to PB2®, a protein-packed peanut butter powder that has all the flavor of peanut butter, but with a fraction of the fat and calories.
While there are so many uses for peanut butter powder (think smoothies, shakes, and dips), we love adding it to oatmeal because it's a breeze to blend in. Add some jam, and you've got yourself a happy little breakfast in a jar!

What you will need
- Rolled oats- Be sure to use old-fashioned oats, not instant or quick cooking. Save the steel-cut oats for my apricot oatmeal.
- Milk- You can use any milk you like.
- PB2 or other powdered peanut butter- You can use any brand of powdered peanut butter.
- Chia seeds- Chia seeds will add a touch of fiber.
- Fruit jam, spread, or jelly- Choose your favorite fruity jam. Use what you would if you were making a PB&J sandwich.
- Bananas, fresh berries, chopped nuts or a drizzle of peanut butter for topping- For added texture (optional).

How to prepare
To assemble these oats, have a few lidded jars or containers ready. The jars should be able to hold about 1 cup (mine hold 10 ounces).

Step 1. Combine oats, milk, PB2, and chia in a small jar. Cover and shake to combine.

Step 2. Refrigerate overnight. When ready to serve, add the jam and any toppings.

👩🍳Expert tip
Choose glass jars or containers over plastic. Plastic containers often leave a residual taste from foods that can leach into the oatmeal. A Mason jar, old jam jars, or a glass jar designed for overnight oats is ideal.
Substitutions
We like these oats just the way they are, but feel free to mix them up however you would like. Here are some great swaps:
- Milk: You can swap out the milk for your favorite almond or other plant-based milk. Vanilla almond milk would be a great choice. Try adding Greek yogurt for even more protein and creaminess.
- Other PB2 varieties: PB2 comes in several flavors, including vanilla almond, cocoa, brownie, cookie, and even a crunchy peanut butter variety, so feel free to experiment. You can also substitute regular peanut butter, though it will increase the calories and fat in the finished recipe.
- Jam: We love the addition of fruity jam because it tastes like a peanut butter and jelly sandwich, but if that's not your thing, you can omit the jam and add a sweetener of your choice. Maple syrup or brown sugar are great options.
Variations
- Fluffernutter- Stir 1 to 2 tablespoons of marshmallow fluff into the oats before serving, or swirl it on top with sliced bananas for a nostalgic peanut butter sandwich-inspired breakfast.
- Chocolate peanut butter- Add 1 to 2 teaspoons of unsweetened cocoa powder to the oat mixture before chilling. You may want an extra splash of milk since cocoa absorbs liquid.
- Chocolate tahini- Swirl 1 to 2 tablespoons of chocolate tahini spread into the finished oats just before serving. Top with sesame seeds or dark chocolate shavings.

Meal prepping and storing overnight oats
Nothing beats having a delicious breakfast ready on the go. You can easily prep these in advance and store them in the refrigerator for up to 5 days. Each day, just remove one container and add your toppings right before eating. Bam-the workweek just got easier!
FAQ's
PB2 is powdered peanut butter. It is made by pressing roasted peanuts to remove most of the oil and then ground into a fine powder. The result is a low-fat, low-calorie, high-protein option for peanut butter that is versatile in cooking and baking.
You can find PB2 (peanut butter powder) in most grocery stores and online. It is found next to the peanut butter or sometimes in the health aisle.
Although overnight oats are meant to be eaten cold, it's not for everyone. Since the oatmeal is already soft, you can certainly heat the oats in the morning if you want a warm breakfast.

Winner with my 8 year old daughter who lives on PB&J!! we used Strawberry jam & fruit 🍓! thanks for sharing!
Gina Shively says
can I use fresh fruit instead of the jam?
Jennifer says
Absolutely!
Ally says
How much would you adjust the plant milk quantity if one wanted to use 2 tablespoons of chia seeds?
Jennifer says
Hi! I'd probably add about 1/4 cup more milk, since chia seeds absorb liquid. You can always add more if needed depending on the consistency you prefer.
