About Vanilla Coffee Overnight Oats

Vanilla Coffee Overnight Oats are a delicious combination of rolled oats, coffee, and milk. It is a breakfast treat for coffee lovers.

These overnight oats with coffee are a perfect grab-and-go breakfast for your travels or busy workdays. They take 5 minutes of working time, and you get ready to eat breakfast the following day.

Double or triple the recipe, transfer it to single-serving mason jars (or glass jars), and meal prep a delicious breakfast for the entire week. Then, you just need to grab one jar and take it with you.

These coffee-flavored oats are vegetarian and gluten-free. You can easily make them vegan as well.

Ingredients

Oats – I prefer rolled oats (also known as old-fashioned oats) for making overnight oats, as they absorb liquid well without becoming mushy.

Don’t use steel-cut oats for this overnight oats recipe, as they will not become soft simply by soaking overnight. And don’t use instant oats; otherwise, they will get mushy.

Coffee – I used instant coffee powder to make coffee oatmeal, but you can use any coffee you prefer. French Press Cold Brew Coffee, an espresso shot, coffee brewed in a Mocha Pot, or even coffee brewed in a simple coffee maker 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 used dark brown sugar. You can also use honey, agave syrup, maple syrup, or other sweeteners.

Chia Seeds – Add some chia seeds, 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 Oatmeal

Add the following ingredients to a medium-sized mixing bowl and mix well.

  • 1 cup rolled oats (old-fashioned oats)
  • 1 teaspoon instant coffee powder

  • 1 teaspoon vanilla extract
  • 2 tablespoon dark brown sugar

Note: Increase the coffee amount slightly if you prefer a stronger coffee flavor.

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 good fats to these oats by topping them with nut butters like almond butter, peanut butter, or pistachio butter.

You can top the creamy oatmeal with chopped nuts, such as almonds, pistachios, walnuts, pecans, or pine nuts.

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, such as bananas, berries, peaches, and mango, also pair well with these.

Nutella, coconut flakes, dark chocolate chips, and whipped cream are some other topping options to consider.

Pro Tips By Neha

You can replace coffee and milk in the recipe with a ready-made vanilla latte.

You can add some Greek yogurt or vanilla yogurt to the oats.

Storage Suggestions

Prepare the coffee vanilla overnight oats and store them in a mason jar or any other covered container in the fridge for up to 5 days.

Although it stays good for five days, I recommend eating it within two days for the best taste.
