Wholesome Ingredients for This Cookie Dough Overnight Oats

What makes these healthy overnight oats so special? Here’s a look at the nutrition-packed ingredients:

Old fashioned rolled oats: These form the creamy base and are high in fiber to keep you feeling full. If needed, use certified gluten-free oats for a gluten-free version.
Vanilla protein powder: Both whey and plant-based varieties work. Choose a clean-label brand for the best results. Pro tip: plant-based protein requires more liquid, so plan accordingly.
Chia seeds: Tiny yet powerful, chia seeds offer omega-3 fatty acids and help thicken the oats for a pudding-like texture.
Cashew butter: This adds a smooth, nutty richness that mimics cookie dough. Swap it for almond butter, peanut butter, or sunflower seed butter if needed.

How to Make Cookie Dough Overnight Oats

In a mason jar or an airtight container, combine the oats, protein powder, chia seeds, cinnamon, and a pinch of salt.
Add the almond milk, cashew butter, maple syrup, and vanilla extract to the dry mix.
Stir well to ensure all the ingredients are thoroughly combined.
Fold in the mini chocolate chips for that irresistible cookie dough appeal.
Seal the container and refrigerate overnight, or for at least 4 hours, to allow the oats to absorb the liquid and soften.

Our Team’s Tips for the Best Cookie Dough Overnight Oats

For the best texture, use old fashioned rolled oats instead of quick oats.
Add the chocolate chips right before serving to maintain their texture if you prefer a crunch.
Batch-prep multiple servings on Sunday night for an easy grab-and-go breakfast all week.
Shake the jar or container before refrigerating if you’re prepping multiple servings.
Store in an airtight container for up to 5 days—just add a splash of milk to refresh the consistency each morning.

Cookie Dough Overnight Oats FAQs

Can I use steel-cut oats instead of rolled oats?

Steel-cut oats require more liquid and soaking time to soften, so they aren’t ideal for this recipe. Stick to rolled oats for the best texture.

Can I freeze cookie dough overnight oats?

Overnight oats are best enjoyed fresh from the fridge, but you can freeze them in individual portions for up to 1 month. Thaw in the refrigerator overnight before eating.

How do I make this recipe more filling?

Add a handful of nuts, seeds, or a dollop of Greek yogurt for additional protein and texture.

What’s the best milk to use for overnight oats?

We love unsweetened almond milk for its light, neutral flavor, but any milk—dairy or plant-based—will work perfectly.

Is this a good post-workout meal?

Yes! These protein-packed overnight oats are an excellent option for refueling after a workout, thanks to their mix of protein, carbs, and healthy fats.
