There are few things in the world I love more than a perfectly tangy key lime pie! The only way to make it better? Pump all that amazing flavor into a nourishing grab-and-go breakfast in the form of these Key Lime Pie Overnight Oats!
What are overnight oats?
Overnight oats are a no-cook form of oatmeal that you mix together and let sit (surprise!) overnight in the fridge. In the morning, you have a creamy-dreamy grab-and-go breakfast that you can eat cold or warm up. If you want more details on everything overnight oats, check out our big Overnight Oats 101 post.
What makes overnight oats so special?
I think that overnight oats should be a meal prep staple. Here’s why we’ll always have them in our rotation:
- Overnight oats are super easy to meal prep. Take just a few minutes on the weekend or in the evening to mix up your oats, and breakfast will be ready to grab-and-go. Overnight oats are not only easy to make in advance—they are designed for it!
- You can customize them to fit your dietary preferences. Make your overnight oats vegan, gluten-free, super nourishing, or super decadent—make them your own! We’re covering key lime pie overnight oatmeal here, but once you get a feel for overnight oats, you can discover your own favorite flavor.
- Overnight oats are just flat-out delicious! This porridge is thick, hearty, and creamy. Who doesn’t want to feel like they are eating pudding for breakfast?
- They can be made in bulk. Overnight oats are a staple on many meal prep menus for a reason—you can make an entire week’s worth of breakfast at once. The only limitation is how many jars you have!
- They can be a healthy (or decadent) way to start the day. You are in full control of your overnight oats, so you can make them as nutrient-dense (try adding super seeds like chia, flax, and hemp) or decadent (try adding some white chocolate) as you’d like.
Do you eat overnight oats cold or heated up?
Most folks eat overnight oats cold (that’s part of the grab-and-go appeal of them), but if you’re not into that (or it is too cold outside), you can warm them in a small saucepan on the stove. Or, you can heat them in the microwave for 30-60 seconds, stirring frequently.
Can I use regular limes, or do I need to use key limes?
I prefer key limes over regular limes because they are more aromatic, which means that sweet lime flavor can really shine through in these overnight oats. But while key limes are cute and small and fun, they tend to be hard to juice. I recommend either buying bottled key lime juice or using regular limes, for ease.
Can you make substitutions to these key lime pie overnight oats?
One of the best things about overnight oats is that they are super easy to customize! You can make all sorts of tweaks to suit your dietary needs or preferences. Need them to be gluten-free, vegan, or lower in sugar? No problem! We cover all sorts of substitutions you can make in our in-depth overnight oats post, but here are some specific swap ideas for these key lime pie overnight oats:
- Make it vegan: Use plant-based cream cheese, plant-based yogurt, and maple syrup. Make sure to double-check your graham crackers for animal products.
- Make it sugar-free: Drop the sweetener, make sure to use unsweetened milk, and add 1/2 mashed ripe banana. Or use stevia or monk fruit sweetener in place of the maple syrup or honey, if you prefer.
- Make it gluten-free: Make sure to use certified gluten-free oats, and don’t add any graham cracker crumbles (or crumbled up gluten-free graham crackers instead).
