Now, I am more of a savory breakfast person. However, when I am craving a sweeter breakfast, I often turn to overnight oats. To me, they taste a lot like dessert yet they’re super nutritious and healthy for you! I always put a scoop of protein powder in mine and it ends up being even higher in protein than my typical egg breakfast. It’s a win-win.

The flavors of key lime pie are all there in these decadent overnight oats – they’re tart, citrusy, creamy and sweet all in the same bite. I added raspberries so it’s a perfectly well-balanced meal. Raspberries are actually one of the highest fiber foods with 8 grams per one cup serving!

Why I Love These Overnight Oats

  • Creamy, decadent and not too sweet. The combination of coconut milk and yogurt makes these overnight oats extra creamy. The lime adds the perfect amount of tartness. Add some whipped cream and graham crackers on top and it’s just so delicious.
  • Easy meal prep. This recipe takes 5 minutes to prep and provides 3 servings for an easy, grab-and-go breakfast in the morning.
  • They’re extremely good for you. You’ve got complex carbohydrates, 1-2 servings of fruit, protein and fiber. There are 26 grams of protein and 7 grams of fiber in each serving. Plus, the live, active cultures from the yogurt help increase the variety of good bacteria in our gut.

Ingredients

Individually portioned ingredients for the raspberry key lime pie overnight oats.
  • 1 cup of old-fashioned rolled oats.
  • 1 cup of vanilla Greek yogurt. Sub with a higher protein plant-based yogurt to make these overnight oats dairy-free.
  • 1 1/4 cups of coconut milk. Can sub with preferred milk it just might not feel quite as creamy.
  • 2 scoops of protein powder, vanilla for best results. Vanilla protein powder will add more sweetness. If using unflavored, just add a little bit more honey to taste.
  • Juice of one lime, with zest per your preference.
  • 2-3 cups of fresh or frozen raspberries. Aim for at least a 1/2 cup of raspberries per serving.
  • 2-3 tablespoons of chia seeds, optional.
  • Topping recommendations: crushed graham crackers, a tablespoon of chopped walnuts, whipped cream, toasted coconut flakes.

How to Make Raspberry Key Lime Pie Overnight Oats

A birds-eye view of the graham crackers, whipped cream, and raspberries on top of the protein overnight oats in two glasses on a counter.

This recipe makes three servings for easy, grab-and-go breakfasts! Easily customize with the various topping ideas but I highly recommend a dollop of whipped cream, crushed graham crackers, and raspberries. If using frozen raspberries, they will thaw and add some sweet juices to the oats, too. Both fresh and frozen are good options!

  1. Add rolled oats, coconut milk, yogurt, protein powder, the juice of one lime, and honey to a large bowl or airtight container. Chia seeds are optional and will likely result in a thicker consistency.
  2. Whisk ingredients together until well-combined.
  3. Refrigerate for at least 6 hours or overnight.
  4. Divide into three servings after refrigeration. Top with crushed graham crackers, raspberries, whipped cream, and lime zest. Enjoy!

I recommend adding the graham crackers on when ready to eat (or the day of) for best results or crumbling them on top of the oats when storing so they don’t get soggy. Store in an airtight container in the fridge for up to 5 days.

Variation Ideas & Tips

  • Increase the fiber content by incorporating 2-3 tablespoons of chia seeds. You may need to add milk or water after refrigeration if it seems too thick (per your preference).
  • If coconut milk solidifies, you may need to warm in microwave
  • Add lime zest on top or in the overnight oats base for a more intense lime flavor.
  • Vanilla protein powder will be sweeter and taste better, depending on the protein powder used.
  • Add a layer of raspberries in the middle if using a mason jar or glass for perfect flavor distribution.
  • Use a higher protein plant-based yogurt, like Kite Hill Greek Style, to make these dairy-free. Check the label of the graham crackers to also ensure they are dairy-free as well.
  • To make toasted coconut: add some butter or avocado spray to a pan with shredded coconut and toast for 5-10 minutes, stirring constantly.

Toppings

  • 2-3 cups frozen or fresh raspberries
  • Crushed graham crackers

  • Add rolled oats, coconut milk, yogurt, protein powder, the juice of one lime, and honey to a large bowl or airtight container.

Notes

  • Vanilla protein powder will add more flavor and sweetness to the oats. If you are using unflavored, add more honey (or preferred sweetener) to taste.
  • If the coconut milk has solidified in the can, microwave for about 45 seconds and stir. 
  • I recommend at least a 1/2 cup of raspberries per serving. Feel free to add a whole cup to reach a higher overall fruit intake. 
  • Layer the raspberries for even distribution, if you prefer. 
  • Use a higher protein plant-based yogurt, like Kite Hill Greek Style, to make these dairy-free. Check the label of the graham crackers to also ensure they are dairy-free as well.
