These PB2 Overnight Oats are peanut buttery, satisfying and so customizable. Made with Greek yogurt, they’re the perfect high protein breakfast for busy days!
Anyone else who loves peanut butter? At home, a jar won’t last more than a week. I usually stir it in my protein oatmeal, blend it in a vanilla protein shake, or drizzle on top of cottage cheese pancakes.
But you know, peanut butter is quite high in calories (sadly). Luckily there’s pb2: it satisfies those cravings without overblowing your macros. My recent obsession is using powdered peanut butter in protein overnight oats.
Why making overnight oats with pb2?
- Quick and easy – You can make them in 5 minutes in a bowl. Refrigerate overnight for a ready-to-eat breakfast in the morning.
- Healthy and diet-friendly – Made with Greek yogurt and powdered peanut butter, they’re high protein, low calorie and gluten-free.
- Satisfying and delicious – If you like peanut butter, this recipe is for you! You can also add more flavor with toppings and mix-ins.
- Meal prep friendly – Prep a larger batch on Sunday and you’ll have no-cook breakfasts for the week.
Ingredients and substitutes
This recipe requires just a handful of ingredients, here are more details along with substitutes. You can find the precise quantities in the recipe card at the bottom.
- Rolled oats – I recommend old fashioned rolled oats, they provide a better texture and more nutrients. Quick oats can also be used, but they tend to get mushy. Just avoid steel cut oats, they require cooking and won’t soak.
- Powdered peanut butter – I used PB2 but any brand (like PBFit) works. If possible, stick to sugar-free and organic options.
- Chia seeds – Optional, chia seeds make your oats creamier, higher in fiber, and more nutritious.
- Maple syrup – It adds natural sweetness without refined sugars. Honey, agave, or ½ mashed banana will also work.
- Greek yogurt – I suggest 2% fat or regular Greek yogurt, plain or vanilla. As a substitute you can use whipped cottage cheese or dairy-free alternatives like soy or coconut yogurt.
- Milk or choice – While unsweetened almond milk and cashew milk are low in calorie, any milk will work. Dairy or dairy-free options like soy or oat milk are great, just avoid added sugars.
Dietary adaptations
- Gluten-free – Stick to certified gluten-free rolled oats and make sure your powdered peanut butter has no gluten.
- Higher in protein – Add to your overnight oats 1 scoop (30 g) of protein powder then fix the texture with 2-3 tbsp of extra milk. You may also use PB2 flavored protein.
- Low calorie – Use nonfat Greek yogurt, unsweetened almond milk or cashew milk, and calorie-free sweetener. Limit high calorie toppings like nut butters and chocolate.
- Diary-free and vegan – Swap Greek yogurt for plant based alternatives. Greek-style soy yogurt is the highest in protein.
Flavor variations
- Cookie dough – Before serving, mix in 2 tsp of chocolate chips. For a healthier breakfast, I recommend extra dark or sugar-free chocolate.
- Berries – Top your PB2 overnight oats with blueberries, raspberries, strawberries or a mix of berries. They pair so well with almond butter!
- Apple cinnamon – While mixing, add ½ tsp of vanilla extract and ⅓ tsp of ground cinnamon. Then, top with diced apple before eating.
- Banana peanut butter – Replace maple syrup with ½ mashed banana, then stir in ½ tsp of vanilla extract and ⅓ tsp of ground cinnamon. Enjoy with slices of banana and a drizzle of peanut butter, if you’d like.
- Double chocolate – Add 1 tbsp of unsweetened cocoa powder or chocolate protein powder. Before serving, stir in 2 tsp of chocolate chips of desired.
Recipe tips
- Use a good powdered peanut butter – Stick to a trusted brand you like. Low quality products can make your oatmeal grainy, chunky and tasteless.
- Adjust the consistency – Oats and pb2 will soak in the liquids while refrigerating. If your porridge gets too thick, stir in a spoonful of Greek yogurt or milk before serving.
- Add mix-ins and toppings before serving – As the oats soak, crunchy bites like walnuts will soften while fruit may oxidize and get black. To preserve texture and freshness, add these only before serving.
How to store pb2 overnight oats?
If you’re prepping ahead, store your PB2 oats in mason jars or airtight containers in the fridge. They’ll stay fresh and creamy for up to 5 days. Just give them a good stir before eating to restore their creamy texture.
For a longer storage, you can also freeze them in freezer-safe jars for up to 2 months. Let them thaw overnight in the fridge and stir your porridge with a spoon or fork before eating.
Frequently asked questions
What is powdered peanut butter?
Powdered peanut butter is a dry, fine powder made from roasted peanuts with most of the fat pressed out. It’s a lighter alternative to regular peanut butter, with fewer calories and around 6 g of protein per 2 tablespoons. Just mix it with water for a spread or use it dry in oats, smoothies, or high-protein desserts.
Where can I find powdered peanut butter?
You can find powdered peanut butter in most big grocery stores, usually near the nut butters or health foods section. Popular brands like PB2 and PBfit are also easy to purchase online from Amazon. I always keep a jar in my pantry, it’s great for oats, shakes, and pb2 protein balls.
Can I heat overnight oats?
Yes, you can definitely heat them if you prefer a warm breakfast. Simply transfer your oats to a microwave-safe bowl or jar and warm in 30-second intervals, stirring between each round, until heated through. Alternatively, you can warm them on the stovetop over low heat.
