Ingredients You’ll Need
These ingredients are simple, affordable, and likely already in your pantry or fridge. Here’s what makes this recipe shine:
The Base
Rolled oats are the star of the show. Old-fashioned rolled oats work best for overnight oats because they soak up liquid beautifully without turning to mush. Avoid instant oats if you can — they tend to get a bit too soft and paste-like overnight.
The Coffee Element
You can use either freshly brewed espresso (cooled to room temperature) or strong brewed coffee. If you have an espresso machine, one or two shots work perfectly. Alternatively, dissolve a teaspoon of instant espresso powder in a tablespoon of warm water — this is the easiest option and delivers a wonderfully concentrated flavor.
The Creaminess
A combination of milk (dairy or plant-based) and Greek yogurt creates the perfect thick, creamy texture. The yogurt also adds a welcome protein boost and a slight tang that balances the bitterness of the espresso.
The Extras
A tablespoon of chia seeds thickens the mixture further and adds omega-3s. A drizzle of maple syrup or honey sweetens things naturally, while a dash of vanilla extract rounds out all the flavors. For topping, dark chocolate chips and a light dusting of cocoa powder are absolutely dreamy.
How to Make Espresso Overnight Oats
This recipe is almost embarrassingly simple. Here’s a quick overview of the process before you dive into the step-by-step instructions:
- Mix your dry ingredients in a mason jar or airtight container.
- Stir in the wet ingredients until everything is well combined.
- Seal and refrigerate overnight (or for at least 6 hours).
- In the morning, give it a stir, add your toppings, and enjoy.
Step-by-Step Instructions
Step 1: In a mason jar or medium-sized bowl, combine rolled oats and chia seeds. Stir to mix the dry ingredients evenly.
Step 2: Add the cooled espresso shot, milk, Greek yogurt, maple syrup, and vanilla extract. Stir everything together thoroughly, making sure there are no dry clumps at the bottom of the jar.
Step 3: Seal the jar with a lid or cover the bowl with plastic wrap. Refrigerate for at least 6 hours, but overnight (8–10 hours) is ideal for the creamiest texture.
Step 4: In the morning, remove the jar from the refrigerator. If the oats seem too thick, stir in a splash of milk to loosen them up. Taste and adjust sweetness if needed.
Step 5: Top with dark chocolate chips, a light dusting of cocoa powder, and a few coffee beans if you’re feeling fancy. Serve cold and enjoy!
Tips for the Best Results
Use the Right Oats
As mentioned, old-fashioned rolled oats are the gold standard here. If you only have quick oats, they’ll still work, but reduce the soaking time slightly to avoid a mushy texture.
Let the Coffee Cool
Never add hot espresso directly to your jar — it can curdle the yogurt and affect the texture. Allow it to cool to room temperature before mixing, or brew it the night before and store it in the fridge.
Meal Prep Like a Pro
This recipe scales beautifully. Simply multiply the ingredients by the number of servings you need, prepare individual jars, and they’ll keep in the fridge for up to 5 days. Add toppings fresh each morning for the best texture.
Adjust the Coffee Intensity
Love a strong coffee flavor? Add a full double shot of espresso. Prefer something milder? Cut it back to half a shot or use regular brewed coffee. You’re in complete control of the caffeine level here.
Topping Ideas to Try
While dark chocolate chips and cocoa powder are a classic pairing with espresso, there are plenty of other delicious ways to top these oats:
- Whipped cream + cinnamon for a cappuccino-inspired vibe
- Sliced banana + almond butter for extra creaminess and natural sweetness
- Crushed hazelnuts + chocolate drizzle for a mocha-hazelnut treat
- Coconut flakes + caramel sauce for a tropical-coffee fusion
- Granola + fresh berries for added crunch and freshness

Frequently Asked Questions
Can I make this without an espresso machine?
Absolutely! Instant espresso powder dissolved in a small amount of warm water works wonderfully. You can find it at most grocery stores or online. Strong brewed coffee is another great alternative.
How long do these overnight oats last in the fridge?
Up to 5 days when stored in a sealed container. Add any fresh toppings just before eating.
Can I eat them warm?
Yes! While overnight oats are traditionally served cold, you can microwave them for 60–90 seconds if you prefer a warm breakfast. Add a splash of milk before heating to prevent them from drying out.
Is this recipe vegan?
It can be! Swap the Greek yogurt for a plant-based alternative (coconut yogurt works great) and use plant-based milk. Replace honey with maple syrup if you use honey as your sweetener.
