Key Lime Pie Overnight Oatmeal

Question: how necessary are key limes for a key lime pie? Would anyone be offended if I used, say, your average lime? Because that’s what I did, and I’m not apologizing for it.


Since my Strawberry Limeade Oatmeal turned out so well, I thought I’d stick with the lime theme and test this Key Lime Pie Oatmeal. It’s citrusy, vibrant, and ever so creamy, thanks to the addition of coconut yogurt.

(I have actually been using Amande almond yogurt lately, but I decided to return to So Delicious coconut yogurt this week. You know what? I think I like this better! I needed time away to remember how much I enjoyed it; absence makes the heart grow fonder.)


This is an incredibly easy recipe that takes only four ingredients and a pinch of salt. The most difficult part is squeezing the lime, and if that’s too difficult for you, you could always just use the bottled lime juice. 🙂 I won’t tell.

    would this work with greek yogurt?

  2. I just found my way here from the internet, looking for something completely irrelevant. I’m glad I distracted myself though, this tasted great! So from all the way from Dubai, UAE, thank you for this!

  3. I’ve been making overnight oatmeal but was looking for some new versions.. this lead me here. This one looks perfect!

    LOVE your recipes! My sister pointed me to your site about a month ago, and I’ve made almost nothing else for breakfast except your various oatmeal recipes since then. This one is a particular favorite, though I needed a bit of sweetener so I added a tsp of honey. And in trying to duplicate the pie a little bit more, I added a crumbled up a graham cracker. Yum!

  5. Christine says:

    Would you recommend using a sweetener of any kind, or maybe vanilla yogurt? I’m thinking that the oatmeal might taste sour otherwise.

    • Lauren Smith says:

      Even though it’s plain yogurt, it’s still sweet to a degree. I found it sweet enough. However, if you prefer your oatmeal sweeter, you could add a sweetener, but I wouldn’t use vanilla yogurt. The vanilla taste would compete with the lime taste. :/

      • Christine says:

        Thanks! Sometimes I use dairy yogurt, and the plain kind is really sour. I’ll make sure to use sweetener then. Whatever the case, I’ll avoid vanilla yogurt for this recipe. I like another commenter’s suggestion about using graham cracker crumbs for topping. That sounds delicious!

    I’ve been curious about this recipe for a long time and finally tried it this morning. Since I used plain dairy yogurt, I added a couple teaspoons of honey so that the oatmeal wouldn’t taste too sour or tart. I used two tablespoons of bottled lime juice. The oatmeal wasn’t as limey as I expected, but maybe I would have gotten different results of I had used a fresh-squeezed lime. I did top my oatmeal with graham cracker crumbs and toasted coconut, which made the oatmeal taste decadent and dessert-like. When I make this again, I’ll try adding a little more lime juice. Lime zest may also be a tasty addition.

    I use a very ripe banana to add to the sweetness.
