Key Lime Pie Overnight Oats

Remember my Lemon Cream Pie Oats? Yeah, me too. I think about them a lot!

But lately, I’ve had a different citrus pie on my mind.


Key Lime.

Yup, I want it. Bad. So, because pie is best for breakfast (right?) and eating a big bowl of cold, creamy, flavorful oats is the nutritional route you know you should go…it’s time for some Key Lime Pie Oats!

Get your goodies together! This one is super simple!

I did’t truly appreciate Key Lime Pie until a year ago. I always thought I didn’t like it. Crazy! Until I tried it…and totally died! I ate a Key Lime Pie Tart from a downtown bakery, and I’ve been smitten ever since.


In fact, I love it so much, that when we were given a free dessert the night my fiance and I got engaged, although chocolate was my first instinct, when I saw Key Lime Pie on the menu, that’s what I got! Yes, I ate Key Lime Pie the night I got engaged.


Maybe all this wedding planning is making me reminisce about that night? Maybe I just really want some pie! Whatever the reason, these oats were definitely the way to go!

    Key Lime Pie has got to be the 8th wonder of the world. We just can’t get enough of it on dessert menus! Now it looks like we’ll be able to recreate a healthier version for breakfast! :)

    I love this idea! I’m always looking for new recipes to jazz up my usual morning oatmeal. I’ve done all of the traditional, and not so traditional, combinations of ingredients, but I haven’t tried a Key Lime version yet! Great idea, and perfect for the warmer weather right around the corner. :)

    OMG I cannot wait to make this! I’ve been seeing lots of posts on Pinterest, Twitter, etc. of “key lime” and this looks like a fabulous way to kick off my morning. I’m totally making this tomorrow night to have after my “hot” yoga class. THANKS! :)

      Thank you SO much! Can’t wait to hear from you once you’ve made it! Nothing sounds more refreshing after hot yoga than cold Key Lime Oats!

      I CAN! Because I didn’t have it for the first time until last year! And I was shocked by how much I loved it! I’ve never been a lime lover (all green Skittles and Sour Patch Kids went straight to the trash) but I tried it, and OMG I LOVED it!!! Buy some Key Limes (they’re adorable, tiny, and green) and make this! You can even use non-dairy yogurt if you want!

    I’ve never actually thought to partially cook my overnight oats…I usually just throw it all together and let it get stiff (tee hee) in the fridge. Hmm, does cooking it first make it fluffier?

    I was NEVER a key lime fan until recently…and while I could pass up the actual PIE just about any day, I really like the flavor! Have you tried Chobani’s new Key Lime Flip flavor? It comes with crushed graham crackers and tiny white chocolate chips…and it’s CHO-mazing! Just had it for the first time the other night…oh yeah, there was some swooning going on between bites! 😉

    And key lime most definitely makes me think of spring! Can’t wait!

      Yes! I partially cook the oats and it comes out way fluffier now!! And if you cook them fully, then stir in even more liquid and throw them in the fridge…volume craziness.
      I’m still waiting on my CHO Flips! But I was so excited to see that flavor!! Lime and white chocolate are a match made in heaven!

    Melissa – rather than coconut extract, can a bit of coconut oil be added? Is the extract just for flavor? I like the idea of getting all the health benefits of coconut oil, in addition to the taste!

    • says

      The coconut extract is for flavor because theres usually a hint of coconut undertones in Key Lime Pie. Honestly, you are totally welcome to try coconut oil in it! But stir it in very well while the bowl is hot before refrigerating it. If you only swirl it in, then overnight the oats in the fridge, you’ll end up with a solid swirl of coconut oil in there :)

    Can I ask why you are cooking the mixture? The whole point of overnight oats is that you DON’T cook them. They are meant to be raw, and time saving!

    • says

      Well certainly you could make yours raw and reduce the liquid. I like to cook mine because it gives it a finer, fluffier texture and a lot more volume because it absorbs more liquid in the long-run. I figure if you’re prepping your meal the night before anyways, adding 2-3 min extra to your prep isn’t going to make or break you, and the results are awesome! I like it much better.
