What Ingredients are in Coffee Overnight Oats?

This recipe keeps things beautifully simple, and honestly, that’s the whole point. You want coffee overnight oats that come together in minutes, not a project that leaves your kitchen looking like a science experiment gone wrong.

Here’s what you’ll need:

• 2 tablespoons instant coffee
• 1 1/3 cups rolled oats
• 1 teaspoon baking powder
• 1/2 teaspoon bicarbonate of soda
• 1 tablespoon caster sugar
• 1 egg
• 200 g Greek yogurt, plus extra for serving
• 200 ml milk
• 40 g unsalted butter, melted
• A pinch of salt
• Icing sugar for dusting

Now, a few things worth mentioning. The instant coffee is your friend here because it dissolves so easily, no waiting around for brewed coffee to cool or dealing with grounds that refuse to cooperate.

Instant coffee dissolves effortlessly, skipping the fuss of cooling brewed coffee or battling stubborn grounds.

Greek yogurt adds that lovely tang and creaminess that makes everything feel a little more luxurious. And the butter, well, it brings richness that ties the whole thing together.

If you’re watching your sugar intake, you could dial back the caster sugar just a touch, though it does help balance the slight bitterness from the coffee. As for the milk, whole milk gives you the creamiest result, but whatever lives in your fridge will work just fine.

How to Make these Coffee Overnight Oats

Getting started is wonderfully straightforward, the kind of thing you can do while still half-asleep, which feels rather fitting for a coffee-based breakfast. First, mix those 2 tablespoons of instant coffee with 2 tablespoons of boiling water and set it aside to cool down a bit.

While that’s happening, grab a bowl and sift together your 1 1/3 cups of rolled oats, 1 teaspoon of baking powder, and 1/2 teaspoon of bicarbonate of soda. Toss in the 1 tablespoon of caster sugar and a pinch of salt, giving everything a little whisper of a stir.

Now here’s where it all comes together like a warm hug in a bowl. In a separate bowl, use a wooden spoon to beat the 1 egg with the 200 g of Greek yogurt, 200 ml of milk, and 40 g of melted butter. Pour in that cooled coffee mixture and stir until everything becomes one beautifully unified batter. The color will be this gorgeous caramel-meets-latte shade, honestly quite lovely to look at.

Add this wet mixture to your dry ingredients and stir gently, just enough to combine. Resist the urge to overmix, lumps aren’t the enemy here, they’re just little pockets of potential.

Transfer everything into your container of choice, whether that’s a mason jar that makes you feel like you have your life together or just a regular bowl with a lid. Pop it into the refrigerator and let the magic happen overnight, those oats slowly softening and soaking up all that coffee-kissed goodness.

Come morning, give it a stir, dollop on some extra Greek yogurt, and dust the top with icing sugar like the first snow of winter settling on a quiet hillside. The aroma alone is worth waking up for.

Coffee Overnight Oats Substitutions and Variations

Because this recipe loves to be played with, you have plenty of room to make it your own.

For the liquid, try any nut milk you enjoy. Almond milk brings a gentle sweetness. Oat milk feels extra creamy. Coconut milk adds a soft tropical whisper.

Your sweetener options are wide open too. Maple syrup works beautifully. A drizzle of honey. A sprinkle of brown sugar. Or nothing at all, if the coffee speaks loudly enough for you.

Flavor variations invite adventure. Add a pinch of cinnamon. A drop of vanilla. A spoonful of cocoa for mocha mornings.

And topping ideas? This is where you play. Fresh berries. Sliced banana. A handful of granola for crunch. Chopped nuts. A swirl of nut butter.

Make it yours.

What to Serve with Coffee Overnight Oats

Your oats are ready, dressed in whatever flavors you chose, and now you might wonder what belongs beside them.

I like to keep breakfast pairings simple. A handful of fresh berries. A sliced banana that softens against the cold oats. Maybe a spoonful of nut butter, melting slowly into something rich.

For tasty toppings, think about texture. Crunchy granola. Toasted coconut flakes. A scatter of dark chocolate chips that feel like a small gift.

Sometimes I set out a cup of fresh fruit on the side. Strawberries cut into hearts. Blueberries that roll like tiny marbles.

A warm drink helps too. Tea, if you want something gentle. Or just water with lemon, bright and clean.

Nothing fancy. Just enough to make the morning feel whole.

Final Thoughts

When you take a few quiet minutes the night before, you give yourself a gift that waits patiently until morning.

That jar in your fridge holds more than oats and coffee. It holds a slower pace. A gentler start. A healthy breakfast that asks nothing of you when your eyes are still soft with sleep.

Your morning routine doesn’t have to feel rushed. It can feel like a deep breath instead.

So tonight, measure your oats. Pour your coffee. Stir everything together with a quiet spoon. Then close the lid and let time do its gentle work.

Tomorrow, you’ll wake to something ready and waiting. Something nourishing. Something made with care by the person who knows you best.

You.
