McDonald’s Iced Coffee Copycat Recipe
McDonald’s iced coffee is one of those drive-through orders that’s genuinely hard to stop buying once you’re hooked. This recipe gives you the same cold, sweet, creamy cup at home for a fraction of the cost, ready in about 5 minutes.
It uses pantry staples and works with whatever milk you have on hand. Make it once and you’ll wonder why you ever waited in that line.

Why I Love This Recipe
The coffee flavor is bold enough to come through the cream and sweetener, which is where a lot of homemade iced coffees fall flat. The trick is using a stronger brew ratio so it stands up to the ice.
It’s also genuinely customizable. Want it less sweet? Use 1 tablespoon of syrup instead of 2. Want it richer? Swap in half-and-half.
This is the version I keep coming back to on weekday mornings when I want something that feels a little more put-together than a straight black cold brew.
Recipe Ingredients

- 1 cup strong brewed coffee, cooled – Brewed at double strength or use cold brew concentrate; this is the backbone of the drink
- 2 tbsp vanilla simple syrup – Store-bought works fine, or make your own with equal parts sugar and water plus a splash of vanilla extract
- 3 tbsp heavy cream – Gives that signature richness; half-and-half works for a lighter version
- 1 cup ice cubes – Standard cubes; crushed ice melts faster and dilutes the coffee
- 1/4 cup whole milk – Whole milk gives the closest result to the original; 2% is a fine swap
Variations / Substitutions
- Hazelnut syrup – Swap the vanilla syrup for hazelnut to get a nutty, slightly toasty flavor that works really well with darker roasts.
- Oat milk – Replace the whole milk and heavy cream with oat milk for a dairy-free version that still has some body and sweetness.
- Brown sugar syrup – Use brown sugar dissolved in warm water instead of vanilla syrup for a caramel-forward, slightly molasses-y flavor.
- Caramel drizzle – Add 1 tbsp of caramel sauce on top for a closer match to the McDonald’s caramel iced coffee specifically.
- Coconut milk – Swap in full-fat canned coconut milk for the cream to get a tropical-leaning richness with a hint of sweetness.

How To Make McDonald’s Iced Coffee
Step 1: Sweeten the Coffee

Pour the 1 cup of cooled strong coffee into a tall glass or shaker. Add the 2 tbsp vanilla simple syrup and stir for about 10 seconds until the syrup is fully dissolved into the coffee.
Cold syrup can sink and stay at the bottom if you skip this step, so give it a real stir now rather than hoping it mixes itself later.
Step 2: Fill the Glass With Ice

Add the 1 cup of ice cubes to a 16 oz glass. Pack it in fairly full so the drink stays cold and the cream doesn’t warm up the second it hits the glass.
Step 3: Pour and Layer the Drink

Pour the sweetened coffee over the ice, then add the 1/4 cup whole milk. Finally, pour the 3 tbsp heavy cream slowly over the back of a spoon held just above the surface of the drink. This keeps the cream floating briefly on top for about 2 to 3 seconds before it starts to drift down through the coffee in ribbons.
That layered look is what makes this feel like a proper coffee shop drink. Once you hand it over or start stirring, it all comes together into a uniform, creamy tan color.
Step 4: Stir and Serve

Give the drink 3 to 4 slow stirs with a long spoon or straw to bring the cream down through the coffee. Serve immediately with a straw, and if you want to take it up a notch visually, add a light caramel drizzle in a spiral around the inside of the glass just before you pour in the ice.
Recipe Tips
- Use coffee that’s fully cooled. Hot or even warm coffee melts the ice fast and waters the drink down within a minute or two. Brew it the night before and refrigerate it, or spread it thin on a sheet pan for 10 minutes to cool it quickly.
- Double-strength brew matters. Use 2 tablespoons of ground coffee per 6 oz of water instead of the usual 1 tablespoon. This keeps the flavor from tasting watery once the ice and milk go in.
- Taste before you pour over ice. Take a small sip of the sweetened coffee before adding milk and cream. It should taste slightly too sweet and slightly too strong at this stage, because the ice and dairy will balance it out.
- Store extra vanilla syrup in the fridge. If you make a batch of simple syrup, it keeps for up to 2 weeks in a sealed jar and makes the next cup take about 90 seconds to put together.
Scale it to your cup size:
| Cup Size | Cooled Coffee | Vanilla Syrup | Heavy Cream | Whole Milk | Ice |
|---|---|---|---|---|---|
| Small (12 oz) | 3/4 cup | 1.5 tbsp | 2 tbsp | 3 tbsp | 3/4 cup |
| Medium (16 oz) | 1 cup | 2 tbsp | 3 tbsp | 1/4 cup | 1 cup |
| Large (22 oz) | 1.5 cups | 3 tbsp | 4 tbsp | 1/3 cup | 1.5 cups |
How To Store
- Refrigerate – If you want to prep this ahead, mix the sweetened coffee (coffee plus syrup, no ice, no milk, no cream) and keep it in a sealed jar in the fridge for up to 3 days. Add the ice, milk, and cream fresh when you’re ready to drink it.
- Serve Cold – This drink is meant to be served immediately over ice. It does not reheat.
Frequently Asked Questions
Can I use instant coffee instead of brewed?
Yes. Dissolve 2 teaspoons of instant coffee in 2 tbsp of hot water, then top it up to 1 cup total with cold water. It works well and the flavor is close enough for a quick weekday drink.
How sweet is this compared to the actual McDonald’s version?
The 2 tbsp of vanilla syrup lands at roughly the same sweetness level as McDonald’s medium iced coffee. If you’ve had theirs and found it too sweet, start with 1 tbsp and adjust from there.
Can I make a big batch for the week?
You can batch the sweetened coffee up to 3 days ahead, but don’t add milk or cream until serving. Dairy mixed into cold coffee starts to separate and get a slightly sour edge after about a day.
What’s the best coffee roast to use?
A medium or medium-dark roast holds up the best once the milk and cream go in. A very light roast can taste thin and acidic against the sweetness; a very dark roast can turn a little bitter.
