Lovers of key lime pie and healthy lime recipes will love these gluten-free Key Lime Pie Overnight Oats! A high-protein oatmeal recipe that requires minimal effort with a perfect balance of sweet and tangy.
Let’s face it, sometimes you want a slice of pie for breakfast and I think it’s simply part of living your best life. What’s not to live about a perfectly fluffy key lime pie straight from the fridge? However, it’s not necessarily a healthy lime dessert recipe and we do like our healthy desserts around here.
This gluten-free Key Lime Pie Overnight Oats Recipe is the perfect way of enjoying our favorite summertime dessert for breakfast while getting all those benefits of eating overnight oats first thing in the morning. It has that perfect balance of creamy, sweet, and tangy that really wakes up those tastebuds and I love that I can make it with just a few simple ingredients.
We’re obviously not blending a slice of key lime pie with oats. No, this overnight oats recipe is made with oats, almond milk, fresh lime juice, and chia seeds and is naturally sweetened with a small amount of maple syrup.
I like to add some protein powder to this mixture to turn this into an overnight protein oats recipe.
To make this taste like a slice of key lime pie, we also add some crushed Graham crackers to mimic a graham cracker crust. The gluten-free kind is widely available these days.

INGREDIENTS NEEDED FOR MAKING THIS HIGH PROTEIN OVERNIGHT OATS RECIPE
You will need the following ingredients listed below to make this healthy breakfast (the exact measurements, nutrition information and the printable recipe card are all below):
- Certified gluten-free oats – if you are not celiac or gluten intolerant, like myself, you can use regular oats.
- Almond milk is my preference but any plant-based milk will work. Regular cow’s milk will work as well if you would prefer to use that.
- Chia seeds up the nutritional value and help thicken the mixture
- Protein powder – I love stirring protein powder into my overnight oats to turn them into protein oats. My favourite protein powder on the market is PEScience, I use their Gourmet Vanilla flavour in almost all of my overnight and baked oat recipes.

- Lime juice – freshly squeezed! Don’t go for the store-bought juice. Fresh key lime juice adds much more depth to the flavour profile
- Lime zest – since you already have fresh limes for the juice, this is a no-brainer. Or key lime zest.
- Maple syrup for sweetness
- Graham Crackers – because not key lime pie without that buttery cinnamon-y graham cracker goodness. Choose gluten-free ones.
- Greek Yogurt, cream cheese and white chocolate are combined to form the top layer aka the ganache. Can use non-dairy yogurt or vegan yogurt if desired.
WHAT’S A GOOD SUBSTITUTE FOR GREEK YOGURT?
I like to use Oikos Greek yogurt here but feel free to use your favorite thick plant-based yogurt instead or go for a low-carb yogurt. Can also use coconut yogurt for a dairy-free option.
DO I HAVE TO USE KEY LIMES FOR THIS RECIPE?
No, regular limes will also taste amazing here. Key limes are obviously more authentic and especially aromatic, but regular limes are often less expensive and more widely available so use what works for you.
Lime lovers will love either anyways with the nice creamy texture and lime flavors.
HOW LONG DO KEY LIME PIE OATS LAST?
You can refrigerate the overnight oat mixture for up to 3 days and that is really already the maximum time I recommend for storage. I know, that’s a bit shorter than what I usually recommend for my overnight oats recipes.
Stored too long in the fridge, anything with lime and lime zest added can become a bit bitter, so I would rather make less and enjoy them while they taste amazing, then make a fresh batch.
WHAT IS THE BEST CONTAINER FOR OVERNIGHT OATS?
There are lots of different options for protein overnight oats.
- Large mason jar – this option is very handy when prepping the overnight protein oats.
- Tupperware or meal prep containers – this option is great when you are prepping a bunch of protein powder overnight oats ahead of time. During the busy mornings you can just grab and go!
- A bowl – this is more so for the stay at home mom who may want to reheat your high protein overnight oats recipe in the morning!

- Once oats are set, break apart a graham wafer for layering, and grate lime peel for zest topping.
- Microwave white chocolate in 30 second increments. Mix in with room temperature cream cheese and greek yogurt. I used a wire whisk to get rid of clumps, and put back in the microwave for 15 seconds for everything to be super creamy and soft.

- In the morning, top with more graham wafer crumbs, lime zest, optional mini lime slices and grab and go!
