What are overnight oats?
If you haven't had overnight oatmeal, it is a method of making oatmeal a bit differently than usual. Instead of cooking oats on your stovetop or microwave and eating them warm, overnight oats are cooked by being soaked with ingredients in the fridge overnight. By having the oats soak in the fridge, they will absorb the liquid and be ready to eat without being cooked in the typical way.

What ingredients do I need?
- Oats - Oatmeal is one my breakfast staples because it's a slow-digesting carbohydrate that will steadily provide energy. For this recipe, the oats are "cooked" by being mixed with other ingredients and sitting in the fridge overnight. I would suggest quick oats.
- Chia seeds - A scoop of chia seeds doesn't add flavor, but several nutrients. They can also help thicken up the oatmeal for a creamy texture.
- Almond milk - The almond milk is going to help "cook" the oats and serve as the liquid that the oats will absorb.
- Key lime greek yogurt - Greek yogurt is going to make the oats extra creamy. It is also an awesome source of protein! The key lime flavor is the best way to easily get a strong key lime flavor to the oats. Your local grocery store likely carries several brand options for this flavor of yogurt.
- Vanilla - A little bit of vanilla will add some extra sweetness to the oats.
- Lime Juice - I like to add the juice from a lime to the oats, just to really maximize the lime flavor in the oats. It's as simple as squeezing half of a lime and letting the juice soak in the oats overnight.
- Honey Bear Bites - The key to the pie crust texture of the recipe is to add crushed honey bear bites (or graham crackers or teddy grahams). The crumbled honey crackers will be such a treat with lime yogurt.
- Optional Add-Ins: Vanilla protein powder, cashew butter, syrup, honey, stevia, slivered almonds, coconut, etc.
What substitutions can I make?
- Oats - Because this recipe is for overnight oats, you definitely need some sort of oats. I use quick oats but you could use gluten-free, flavored, or whatever kind you like best.
- Chia seeds - This is an optional ingredient and the recipe will still turn out great if you don't add these seeds.
- Almond milk - Any other kind of milk will work well for this recipe so you can choose whatever matches your dietary needs.
- Key lime greek yogurt - I would recommend keeping this flavor of yogurt so you definitely get the key lime flavor, but you could use any kind of yogurt. For example, greek, low-fat, or dairy-free options will all work.
- Honey Bear Bites - I would definitely add some sort of graham cracker addition, whether it's a regular graham cracker or honey teddy graham. My favorite are Honey Bear Bites because they're packed with protein!
- Vanilla - I like to add vanilla for the flavor, but you could leave this out and would be okay.
- Lime Juice - If you don't have a fresh lime, you could use any kind of lime juice.

I love this recipe! It is so quick to put together the night before. I have made overnight oats before, but never thought about using lime yogurt. I do add some protein powder in with the yogurt to up the protein. I would definitely recommend this to anyone looking for a good quick breakfast.
Megan says
These were so good and so easy! Not too sweet or tart and I love the graham cracker crunch ?
Theresa D. says
Love, love, love these. So easy and delicious. A nice change of pace from the other overnight oat recipes I’ve made.
Anna says
I cannot wait to try these for meal prep! Do you add the graham crumbles to sit overnight and then top with more or do you just garnish them with the crumble? I want to get this right!
Jordan Smith says
I have made it both ways! I love the crunchy texture on top so ofter add them on top for serving. But if you're crunched for time, you can just mix them in!
