Ingredients

Oats – I prefer rolled oats (old fashioned oats) to make overnight oats as they soak up well without getting mushy.
Don’t use steel-cut oats for this overnight oats recipe.
Coffee – I used instant coffee powder to make coffee oatmeal, but you can use any coffee you prefer. French press cold brew coffee, espresso shot, coffee brewed in a mocha pot, or even coffee brewed in a simple coffee brewer also works fine.
If using brewed coffee, then reduce the amount of milk slightly.
Milk – Use whole milk (full-fat milk) for the creamiest texture. You can use skim milk or low-fat milk if you are watching your weight.
To make a vegan version, replace dairy milk with any plant-based milk (dairy-free milk) like almond milk, soy milk, coconut milk, oat milk, etc.
Vanilla Extract – Adding vanilla extract gives the oats a nice and distinct flavor and aroma.
Dark Brown Sugar – To add sweetness to the overnight oats, I have used dark brown sugar. You can also use honey, agave syrup, maple syrup, etc.
Chia Seeds – Add some chia seeds that are packed with nutrients. They fluff up a bit when soaked in milk and add a great texture to the oats.
Add a little cocoa powder or chocolate syrup to add chocolatey flavor.
Add some protein powder if making it for your pre- or post-workout meals.
How To Make Coffee Overnight Oats
Add
- 1 cup rolled oats (old-fashioned oats)
- 1 teaspoon instant coffee powder
- 1 cup whole milk
- 1 teaspoon vanilla extract
- 2 tablespoon dark brown sugar
- 2 teaspoon chia seeds
to a medium-sized mixing bowl and mix well.
Note – Increase the coffee amount slightly if you like a stronger coffee flavor.


Cover the bowl with a lid and refrigerate overnight or for at least 4 hours.

Thin out with some extra milk if the oats are too thick for your liking.

Serve chilled or heat it in a microwave to serve warm.
Garnish with cocoa nibs before serving.

Topping Ideas
I like to keep things simple and top these coffee-flavored oats with just cacao nibs, but you can add more toppings to make them even more filling and nutritious. Here are some ideas
Add healthy fats to these oats by topping them with nut butter like almond butter, peanut butter, pistachio butter, etc.
You can top the creamy oatmeal with chopped nuts like almonds, pistachios, walnuts, pecans, pine nuts, etc.
Seeds like chia seeds, sunflower seeds, toasted sesame seeds, pumpkin seeds, flax seeds, and hemp seeds are also great for topping oats.
Chopped seasonal fruits like bananas, berries, peaches, and mango also go well with these.
Nutella, coconut flakes, dark chocolate chips, whipped cream, etc., are some other topping options that you can consider.
Pro Tips By Neha
You can replace coffee and milk in the recipe with a readymade vanilla latte.
Add some Greek yogurt or vanilla yogurt to the oats to make them healthier.
Storage Suggestions
Prepare the coffee vanilla overnight oats and store them in a mason jar or any other covered container for up to 5 days in the fridge.
Although it stays good for five days, I recommend eating it within two days for the best taste.
