Ingredients

1/2 cup old-fashioned rolled oats
1 scoop vanilla or unflavored protein powder approximately 1/4 cup
1 tablespoon chia seeds
1/8 teaspoon fine sea salt
3/4 cup unsweetened almond milk or milk of choice
2 tablespoons creamy peanut butter
1 teaspoon maple syrup or other liquid sweetener, optional
1/2 teaspoon vanilla extract

Instructions

In a medium-sized jar with a tight-fitting lid or a small meal prep container, combine the old-fashioned rolled oats, protein powder, chia seeds, and fine sea salt. Use a spoon to stir thoroughly, ensuring all the dry ingredients are evenly distributed.
Add the unsweetened almond milk, creamy peanut butter, maple syrup (if using), and vanilla extract directly into the jar with the dry mixture.
Stir the mixture vigorously with your spoon, breaking up any clumps of peanut butter and ensuring all the ingredients are fully incorporated. Scrape down the sides of the jar as needed to prevent any dry pockets of oats or protein powder.
Once the mixture is uniform and smooth, secure the lid tightly onto the jar or container.
Place the sealed container in the refrigerator and allow the oats to chill for a minimum of 4 hours, or preferably overnight. This resting time allows the oats and chia seeds to fully absorb the liquid and thicken to a rich, creamy consistency.
The next morning, remove the jar from the refrigerator. Give the oats another good stir. If the consistency is too thick for your preference, add 1 to 2 tablespoons of additional milk, stirring until you achieve your desired creaminess.
Serve the high protein peanut butter oats chilled, directly from the jar, or transfer them to a bowl. Enhance your meal with optional toppings such as extra peanut butter, a drizzle of maple syrup, fresh fruit like sliced bananas, or a sprinkle of chopped nuts.

Notes

Give the oats a good stir before serving. Add extra milk if too thick. Top with extra peanut butter, maple syrup, sliced bananas, or chopped nuts.

Creative Ways to Customize Your Oats

Chocolate Peanut Butter: Stir in a tablespoon of cocoa powder with the dry ingredients for a decadent twist.
Berry Blast: Layer in fresh or frozen berries like raspberries or blueberries before refrigerating.
Tropical Vibes: Use coconut milk and top with shredded coconut, mango, and a sprinkle of macadamia nuts.

My Pro Tips for Perfect Oats Every Time

Stir Thoroughly: Take an extra moment to mix until no clumps of protein powder or peanut butter remain for a perfectly smooth consistency.
Patience is Key: Allow a full overnight soak for the oats and chia seeds to fully hydrate and thicken, just like my classic overnight oats.
Adjust to Taste: After chilling, taste and adjust. You can always add more milk for thickness or a drizzle of syrup for sweetness.
Use a Quality Jar: A container with a tight-fitting lid prevents leaks and ensures everything mixes well when you shake it.

How to Store and Enjoy Your Oats Later

Store: Keep prepared oats in an airtight container in the refrigerator for up to 4 days, making them ideal for weekly meal prep.
Freeze: For longer storage, freeze individual portions for up to 2 months. Thaw overnight in the fridge before enjoying.
Reheat: While best served cold, you can gently warm them in the microwave for 60-90 seconds if you prefer a hot breakfast.
Make-Ahead Tip: Prepare multiple jars on Sunday for a ready-to-go high protein breakfast all week, freeing up your mornings.

Frequently Asked Questions

Can I use quick oats instead of old-fashioned oats?

I recommend old-fashioned rolled oats for the best texture, as they hold their shape well overnight. Quick oats will work but will result in a much softer, almost mushy consistency because they absorb liquid more quickly.

What type of protein powder works best?

Vanilla or unflavored whey or plant-based protein powders integrate beautifully. I suggest avoiding chocolate flavors unless you specifically want chocolate peanut butter oats, as they can overpower the other ingredients.

Why are my peanut butter oats too thick?

This is easily fixed. Simply stir in an additional tablespoon or two of your milk of choice until you reach your preferred creamy consistency. Different protein powders and chia seeds can vary in their absorption rates.

Can I make this recipe without chia seeds?

Yes, you can omit them, but your oatmeal will be much thinner. The chia seeds are crucial for thickening the mixture into a spoonable, pudding-like texture as it rests.
