Step‑by‑Step Instructions for Key Lime Pie Overnight Oats
Step 1: Combine the Base Ingredients
In a mixing bowl, combine rolled oats, 1 cup of milk (dairy or non-dairy), and ½ cup of Greek yogurt. Add 2 tablespoons of honey or maple syrup, ¼ cup of fresh lime juice, and 1 tablespoon of lime zest into the mix. Stir well for about one minute until all the ingredients are smooth and evenly incorporated, ensuring the oats are fully coated.
Step 2: Transfer to Storage
Carefully pour the mixture into a jar or an airtight container. Make sure to leave some space at the top to allow the oats to expand as they soak up the liquid. Using a spatula can help scrape out every last bit from the bowl, ensuring you don’t miss any deliciousness from your Key Lime Pie Overnight Oats.
Step 3: Refrigerate
Seal the jar or container tightly and place it in the refrigerator. Let the oats chill and absorb the flavors for at least 4 hours, preferably overnight. As the mixture sits, the oats will soften, creating a creamy texture reminiscent of classic Key Lime Pie, perfect for a refreshing morning treat.
Step 4: Final Touches Before Serving
Once your Key Lime Pie Overnight Oats have set, take them out of the fridge. Give the mixture a good stir to combine any settled ingredients, achieving a consistent texture. To add a delightful crunch, sprinkle 2 tablespoons of graham cracker crumbs on top of the oats before serving, enhancing the pie-like experience.
Step 5: Serve and Enjoy
For an extra zesty touch, you can garnish with lime slices or a dollop of whipped cream. Serve immediately for a vibrant start to your day. These Key Lime Pie Overnight Oats not only satisfy your taste buds but also make breakfast feel like a little celebration, fueling you with energy and joy.

Key Lime Pie Overnight Oats Recipe FAQs
What type of oats should I use for Key Lime Pie Overnight Oats?
Absolutely! For the best results, use rolled oats as they provide a nice structure and texture. If you require a gluten-free option, just make sure to select certified gluten-free rolled oats. Steel-cut oats won’t work here, as they require longer soaking times and won’t achieve that creamy consistency.
