Ever dreamt of eating key lime pie for breakfast?! Well me too, and look no further than these key lime pie overnight oats! They are bursting with those classic pie flavors thanks to tart key lime juice, some key lime zest, and buttery crushed graham crackers! You only need 8 ingredients to make these overnight oats, and no special equipment. You can make a big batch of these at the beginning of the week so you've got easy meal-prepped breakfasts for the week. One of my favorite grab-and-go breakfasts will now be one of your favorites as well.
You guys know that I can't get enough of overnight oats as a certified breakfast lover. I also love me a good pie, specifically key lime pie. In the summer, it's all I can think about! After making my blueberry cheesecake overnight oats and birthday cake overnight oats, I thought it would be fun to make another classic dessert into a breakfast recipe!
These key lime pie overnight oats are just like your favorite nostalgic pie, but in overnight oats form! You get the key lime flavor thanks to key lime zest and juice, then I've added some crushed graham crackers for extra crunch and flavor. All the things you love about key lime pie, but in a filling and hearty breakfast that will jump start your day the right way.
If you really want to be indulgent, top these overnight oats with whipped cream! These overnight oats are a piece of pie (ok fine, a piece of cake!) and only take a few minutes to prep. I love making a large batch of these so I've got breakfast prepped for the week.
ingredients you will need
- Old Fashioned Oats: I recommend using old fashioned oats or rolled oats. They'll give you the best texture that isn't too mushy or too firm. I don't recommend using quick oats because those will get mushy overnight, and steel-cut oats are too hard. I love these protein oats for added protein!
- Chia Seeds: the chia seeds will absorb some of the liquid, help with texture, and make your overnight oats creamier.
- Crushed Graham Crackers: a must for all the key lime pie flavors! I add these at the end for extra crunch, but you could also crush some into the oats as well.
- Milk: feel free to use regular milk or dairy-free milk.
- Greek Yogurt: this will make your overnight oats creamy and help keep you fuller for longer. I found key lime yogurt at my local grocery store and it was so good in this recipe!
- Honey: this will help sweeten the oats, swap it out for maple syrup in a pinch.
- Key Limes: using juice and zest here- sometimes key limes are hard to find in store though, so I love this key lime juice in a pinch!
How to make
mix dry ingredients
add wet ingredients
mix together & let sit in the fridge
Making these overnight oats is easy & quick, which is typically my requirements for a breakfast recipe!
- start by mixing together the oats and chia seeds
- add in all your wet ingredients- milk, yogurt, key lime juice, honey. Mix until well combined (I usually make it in a jar with a lid so I can give it a good shake)
- Place in the fridge overnight!
Easy as that! I top mine with fresh zest, some crushed graham crackers, and whipped cream if I'm feeling wild (which I typically am).
What are key limes, and what if I can't find them?
Key limes are also known as Mexican limes. They're more yellow and much smaller (like lil mini limes, so cute!) compared to regular limes, which are more green and have a thinner skin. Key limes are more tart and sour than regular limes and almost have a floral flavor. I sometimes have a hard time finding them in my local grocery stores, which stinks but is understandable.
I typically like to buy premade key lime juice anyway, so no worries if you can't find actual key limes! Saves you time anyway so you don't have to juice any limes. Regular limes (also called Persian limes), can be used if you can't find key limes!
Storage and Meal Prepping
Store in an airtight container in the fridge for up to 5 days. Don't top them with whipped cream or graham cracker crumbs until you're ready to serve- graham crackers will get soggy as they sit on the oats!
If you want to meal prep these, just multiply the recipe by how many servings you want to make. I prefer making them in individual jars for easy access, but you could make one big batch in a larger bowl if you want and scoop as you go.
