Can you put coffee in overnight oats?

Yes. Mix cooled, strong coffee into the base the night before. It soaks in with the milk and flavours the oats by morning.

Does the salt really matter?

A small pinch makes the caramel and coffee taste fuller and less flat. Without it, the jar is simply sweet.

Can I use instant coffee?

Yes. Dissolve it in a little water first, let it cool, then mix it into the base.

Why it works

Coffee gives the oats a gentle bitterness and a little caffeine. Caramel brings the sweetness. The pinch of sea salt is what ties it together, sharpening both so the jar tastes like a salted caramel coffee rather than a sweet one.

Use strong, cool coffee

Brew it stronger than you would drink it, because the oats and milk dilute it. Let it cool before mixing it in, or it warms the whole jar before it reaches the fridge. Instant coffee dissolved in a little water works too, if a pot feels ambitious at night.

Caramel, then salt, then eat

Drizzle the caramel just before eating so it stays glossy on top. Then the salt. A tiny pinch. Flaky salt is nice if you have it. This is one of those instructions that looks optional and isn't.

If you are using a homemade base

Soak rolled oats overnight in milk with chia and a few almonds, with the cooled coffee mixed in.

Storage

Keeps covered in the fridge for a day. The coffee flavour gets a touch stronger by morning. One serving: around 470 calories, 14g protein and 9g fibre.
