Flat white is the coffee shop drink you can make at home in five minutes, with a strong espresso base and a thin, velvety layer of steamed milk. I started making these on slow weekend mornings to skip the cafe line, and now Jason requests one with breakfast every day. If you love fun drinks, our boba tea is another homemade favorite.
All you need is instant espresso, hot water, and milk to make a flat white that rivals your local barista.

Why This Recipe Works
Click to see the technique science
- Instant espresso is the shortcut. Quality instant espresso powder gives you a bold, true espresso flavor with no machine required.
- Microfoam, not big bubbles. Frothing the milk until it is silky and fine is what gives a flat white its signature velvety texture.
- A higher coffee-to-milk ratio. A flat white uses less milk than a latte, so the rich espresso flavor really comes through.
- Warm the milk first. Heating the milk to about 150 degrees helps it froth into smooth microfoam and keeps the drink hot.
- Pour slowly. Pouring the milk in slowly lets the foam settle into a thin, even layer instead of a big airy cap.
- Five minutes, no cafe. You get a barista-style coffee at home in less time than it takes to drive to the shop.
Why You’ll Love This Recipe

Key Ingredients
Here is what makes this flat white so good. See the recipe card for exact amounts.
- Instant espresso powder: The shortcut to bold espresso flavor with no machine; look for a quality brand for the best taste.
- Hot water: Dissolves the espresso powder into a strong, concentrated coffee base.

Variations and Substitutions
Here are a few easy ways to make this flat white your own.
- Dairy-free: Use oat or almond milk; barista-style versions froth up best.
- Iced flat white: Pour the espresso and cold frothed milk over a glass of ice.
- Flavored: Add a pump of vanilla, caramel, or hazelnut syrup to the espresso.
- Extra strong: Use two teaspoons of espresso powder for a bolder drink.
- Pair it with a sweet treat like our caramel milkshake for the coffee lovers.
How to Make Flat White
- Add the espresso powder to your favorite mug, then pour in the hot water.
- Stir until the espresso powder is fully dissolved, adding sweetener now if you like.
- Froth the warm milk with a handheld frother until it is silky and full of fine microfoam.
- Slowly pour the frothed milk into the espresso, holding back the foam, then spoon a little foam on top.
Recipe Tips & Tricks
- Heat the milk to 150 to 155 degrees; too hot scalds it and ruins the foam.
- Use a handheld frother for the easiest, silkiest microfoam.
- Whole milk froths best, but barista-style oat milk is a great dairy-free option.
- Hold back the foam as you pour so you get a thin layer, not a thick cap.
- Use a good instant espresso; the flavor of the whole drink depends on it.
- Warm your mug with hot water first so the drink stays hot longer.
- Add sweetener to the hot espresso, not the milk, so it dissolves completely.
Serving Ideas and Suggestions
A flat white is best enjoyed fresh and hot, right after you pour the milk. Sip it on its own as a morning pick-me-up or alongside breakfast.
It pairs beautifully with something sweet. Serve it with a pastry, or set it next to a boba tea when friends come over for a fun coffee-and-tea bar.
For a treat-yourself afternoon, make a flat white to go with our caramel milkshake or a shamrock shake. There is a coffee or shake for everyone.
Flat White FAQs
A flat white is an espresso-based coffee drink topped with a thin layer of steamed milk and fine microfoam. It has a higher coffee-to-milk ratio than a latte, so the espresso flavor is bold and front and center.
A flat white has less milk and a thinner layer of microfoam, so it tastes stronger and more espresso-forward. A latte has more steamed milk and a thicker foam cap, making it milder and creamier.
Yes. This recipe uses instant espresso powder dissolved in hot water for the espresso base, and a handheld frother for the milk, so no machine is needed at all.
Whole milk is traditional because it froths into the silkiest microfoam. For a dairy-free version, barista-style oat milk froths beautifully and has a naturally sweet flavor.
Warm the milk to about 150 to 155 degrees Fahrenheit. That is hot enough to create smooth microfoam without scalding the milk, which would give it a burnt taste and ruin the foam.
Absolutely. Stir your sweetener of choice, whether sugar, honey, or flavored syrup, into the hot espresso before adding the milk so it dissolves completely and blends evenly.

Notes
- If your milk is cold, you’ll need to heat it to about 150-155°F for a good flat white. Don’t overheat, or it might scorch.
- If you don’t have a steam wand, you can use a handheld frother, a French press plunger, or even shake warm milk in a jar. Just watch for spillage!
- Typically, a traditional flat white is 1 part espresso to 2 parts milk, or thereabouts. But you can tweak it to suit your taste.
- Once you have your micro foam, tilt your milk jug or container and pour in a thin stream to avoid big bubbles on the surface of the drink.
- If you have an espresso machine, pick a best coffee beans brand you love. A stronger coffee flavor helps the drink shine.
- If you want latte art, swirl the milk gently near the top of the espresso—just for fun, even if it’s not perfect.
