What do overnight protein oats taste like?

These make-ahead oats are smooth, creamy, and thick, like the best stovetop oatmeal porridge without any fuss or extra dishes. This recipe is flavored with peanut butter, banana, cinnamon, and vanilla — a delectable combo I turn to time and again!

I personally like to make them as stated in the recipe, then add a little more almond milk and heat them up in the morning. It makes them a little more milky, cozy, and all-around comforting. Feel free to eat them chilled like an oatmeal pudding if you prefer.

Ingredients

As promised, you need fewer than 10 simple ingredients to make this overnight oats protein powder porridge. Here’s what to grab:

• Old-fashioned rolled oats – These are the best type of oats to use for this overnight oatmeal recipe, because they get soft while still maintaining a lovely texture. Don’t use instant or quick oats (they get really mushy) or steel-cut oats (they never soften up enough).
• Unsweetened almond milk – To give your oats a creamy, dreamy consistency.
• Chia seeds – I like to add chia seeds to most of my breakfasts, simply because they add a ton of fiber and are a great source of omega-3 fatty acids.
• Peanut butter – For an added boost of flavor and extra protein. I’m a fan of creamy peanut butter, but you can use crunchy if you like extra texture.
• Vanilla extract – For added flavor and complexity. Make sure to use pure vanilla extract instead of imitation flavoring, which is highly processed and definitely not good for your health.
• Maple syrup – The main sweetener in this recipe. It adds some sweetness without overpowering the other flavors. Just like vanilla extract, make sure to use 100% pure maple syrup!
• Cinnamon – I love adding cinnamon to this recipe. It makes the oats taste a little sweeter without adding more sugar.
• Vanilla protein powder – Use a high-quality protein powder that isn’t chalky and doesn’t have a weird aftertaste. Designer Whey is my favorite go-to protein powder, and I use it in all kinds of recipes like protein coffee, protein donuts, and all of my morning smoothies.
• Banana – The last ingredient, sliced bananas on top of your overnight oats gives them texture and another delicious flavor!

Substitutions

While I love this overnight oats recipe with protein just the way it’s written, there is PLENTY of room for you to make it your own. Here are a few quick and easy substitutions you can make depending on your needs and preferences:

• Old-Fashioned Oats – While neither instant/quick oats nor steel-cut oats are appropriate for this recipe, feel free to swap in certified gluten-free rolled oats if needed.
• Almond milk – I like to use the unsweetened vanilla flavor, but you can use any type of milk you’d like to! Regular dairy milk, soy milk, coconut milk, cashew milk, oat milk, rice milk, or any non-dairy milk would all work great in this protein-packed breakfast recipe. You can also substitute part or all of the milk for leftover coffee to get a little caffeine with your meal. Just note that the nutrition facts listed below are based on almond milk. 🤓
• Chia seeds – You can easily swap in golden flax seeds here, or omit them altogether.
• Peanut butter – You can also swap in any nut or seed butter you want. Almond butter, cashew butter, or sunflower butter would also work great.
• Vanilla extract – You’re welcome to use an equal amount of vanilla powder or vanilla paste, or half as much ground vanilla seed instead. You can also experiment with different flavors here like almond extract, lemon extract, or maple extract.
• Maple syrup – Feel free to experiment with other liquid sweeteners like honey, agave nectar, date syrup, or brown rice syrup.
• Cinnamon – Other warming spices like pumpkin pie spice, apple pie spice, cardamom, ginger, or nutmeg are excellent options. Feel free to mix and match to find your favorite flavors! You’re also welcome to use cocoa or cacao powder for a chocolate-flavored breakfast if you like.
• Vanilla protein powder – You can also swap out the flavor like chocolate protein powder, to give your oats a makeover! Just make sure to choose a high-quality type of protein powder that isn’t chalky.
• Banana – Depending on what’s in season or what’s in your budget, you can easily trade out the bananas for your favorite fruits. Try fresh or frozen berries, stewed apples or pears, or fresh or frozen mangoes. You’re also welcome to use a dollop of Homemade Chia Seed Freezer Jam if you prefer!

Tips & FAQ

• Feel free to make a bigger batch! Simply hover your cursor over the “servings” portion of the recipe card and drag to however many you like. This is a great move for families so everyone has a cup ready to go in the morning. It’s also ideal if you like to meal prep. They’ll keep well in the fridge for up to 4 days.
• Use a mason jar for simple storage. Not only are they airtight (perfect for tossing in your bag as you walk out the door), but can also be stacked in the fridge, and microwaved (so long as you remove the metal lid).
• Cut down on dishes by mixing the protein oat mixture directly in your storage container.
