Making a refreshing instant iced coffee at home is simple.

You only need a few ingredients, which are likely already in your kitchen.

Instant Coffee Granules

Start with 1-2 tablespoons of instant coffee granules.

This will be the base of your drink.

Adjust the amount based on how strong you like your coffee.

Hot Water

You’ll need 2 tablespoons of hot water from the tap.

This small amount helps to dissolve the coffee granules quickly and thoroughly.

Cold Water

Next, you’ll need 6-8 ounces of cold water.

This cools down the coffee mixture, preparing it for the ice.


1 cup of ice will do here.

The ice not only chills the coffee but also adds a refreshing element.

Half n Half or Milk

Finally, you’ll ned about 3 tablespoons of half n half or any milk of your choice.

This adds creaminess to the coffee, balancing its flavors.

Optional Sweeteners

Lastly, you can also customize your drink with sweeteners.

Options include simple syrup, stevia, or sweetened creamer.

These can enhance the taste according to your preference.

Step-by-Step Instructions

Step 1: Dissolve Coffee

Start by adding 1-2 tablespoons of instant coffee granules to a large 8-12 oz glass.

Pour in 2 tablespoons of hot water from the tap.

Stir the mixture until the coffee granules are fully dissolved.

This step ensures that your coffee is smooth and free of any clumps.

Step 2: Add Cold Water

Next, pour in 6-8 oz of cold water.

The amount of cold water can be adjusted depending on the size of your glass and your preference for coffee strength.

Stir the mixture well to combine the dissolved coffee with the cold water.

Step 3: Add Ice

Add 1 cup of ice, or as much as you like.

The ice helps chill the coffee quickly, making it refreshing and ready to drink.

The amount of ice can be adjusted based on how cold you like your coffee.

Step 4: Add Milk

Pour in 3 tablespoons of half n half, milk, or any creamer of your choice.

Stir the mixture to combine the milk with the coffee.

This adds a creamy texture to your iced coffee, enhancing its flavor.

Step 5: Sweeten (Optional)

If you prefer your coffee sweet, you can customize it with your choice of sweeteners.

Add sugar, simple syrup, or flavored syrups such as vanilla or caramel.

Stir well to ensure the sweetener is evenly distributed.

Variations and Customizations

Stronger Coffee

If you prefer a bolder flavor, simply use more instant coffee granules.

Adding an extra tablespoon can give your iced coffee a more robust taste.

Flavored Iced Coffee

Vanilla, caramel, or hazelnut syrups can add a delightful twist.

Just stir in a teaspoon or two of your favorite syrup to create a delicious, customized drink.

Dairy-Free Options

For a dairy-free version, use plant-based milks like almond, soy, or oat milk.

These alternatives can provide the same creamy texture and are perfect for those who are lactose intolerant or prefer a vegan option.

Low-Carb/Keto Options

To make a low-carb or keto-friendly iced coffee, skip the sugar.

Instead, use keto-approved sweeteners like erythritol or stevia.

These sweeteners will keep your coffee tasty without adding extra carbs.

Blended Iced Coffee

For a smoother, slushy texture, blend your iced coffee with ice.

This creates a refreshing and frosty drink, perfect for hot days.

Simply combine all the ingredients in a blender and blend until smooth.

Tips for the Perfect Instant Iced Coffee

Using Cold Water

Instant coffee can dissolve in cold water, but it takes a bit longer.

Stir your coffee for an extended period, about a minute or so, to ensure the granules are fully dissolved.

This step is crucial for achieving a smooth, grit-free drink.

Ice Cubes

To avoid diluting your coffee, use coffee ice cubes instead of regular ice.

Simply freeze some of your prepared coffee in an ice tray.

When these cubes melt, they will keep your drink strong and flavorful.

Milk and Creamer

For a creamier texture, shake your milk before adding it to the coffee.

This adds air to the milk, making it frothier and richer.

Whether you use regular milk or a dairy-free alternative, this trick enhances the overall texture of your iced coffee.


If you want to prepare your iced coffee in advance, store the coffee mixture without ice in the fridge.

This way, you can keep it fresh and ready to use.

Just add ice and milk when you’re ready to drink it.

This method also allows you to make a larger batch and enjoy it over several days.
