Sometimes you want oatmeal for breakfast. Sometimes you want a slice of pie. It’s called balance sweetie. Instead of just blending a slice of key lime pie and mixing it with some oats, I made these key lime pie overnight oats instead. They’re creamy. They’re easy. And a little bit sweet, a little bit tangy. Just like me.

How to make these key lime pie overnight oats

Start by combining 1/2 cup of rolled oats with 1/2 cup of milk (you can use whatever milk you prefer. I used unsweetened soy milk), 1 tablespoon of lime juice, 1 teaspoon lime zest, 1 teaspoon vanilla extract, 1 teaspoon chia seeds, 1/4 cup plain Greek yogurt, and 1 to 2 teaspoons of honey in a mason jar with a lid, or a resealable bowl.

Refrigerate at least 4 hours, or preferably overnight. Before serving, crumble one square of a honey graham cracker over the top. Sprinkle with extra lime zest if desired.

Pro Tips

Don’t add the graham cracker until you’re ready to eat. This helps make sure they stay crispy, just like a graham cracker crust!
You can use either key limes or regular limes in this recipe. Key limes are more authentic and aromatic, but regular limes are often less expensive and available.
Make these a little more dessert-like with a dollop of whipped cream on top!

FAQs

Can these overnight oats be heated up?

You can warm these oats up if preferred, BUT I wouldn’t heat them too much since the yogurt in this recipe can break with higher heat. If you want them to be hot oats, I would leave out the yogurt all together.

Do you have to cook the oats, or can they be eaten raw?

That’s the beauty of overnight oats – no cooking required! Letting the oats soak softens them, while taking on a lot of flavor without needing to cook or heat.

How long do these overnight oats last?

You can refrigerate the overnight oat mixture for up to 2 days. I wouldn’t suggest going too long in the fridge, since the lime can become bitter. Luckily they don’t take long at all to make!

Money-Saving Tips for these Key Lime Pie Overnight Oats

Buy in bulk. Opt for larger containers of items you use often like oats, honey, chia seeds, or yogurt instead of smaller containers. These are often more cost-effective options.
Buy store brands. Utilize store brands for basics like vanilla, oats, and milk, as they are often less expensive without sacrificing flavor or quality.
