This oat beverage is served over ice for a creamy and perfectly balanced taste and a perfect café-style iced coffee feel.

I’ve made this iced oat latte more times than I can count, especially when I want something that feels a little special without putting in too much effort. Today I am recreating it with a whipped dalgona coffee topping, which instantly makes it creamier, lighter, and more fun to drink.

What I really love about this version is how balanced it feels. The oat milk keeps the base smooth and slightly sweet, while the whipped coffee adds that bold, slightly bitter contrast. As you mix it, the foam slowly blends in to make a creamy iced latte that tastes just like a café-style drink, but fresher and more customizable.

You can swap brown sugar with any sweetener of your choice. You can also swap cinnamon with cardamom or completely omit it. This can also be made into hot coffee when you use hot milk and no ice. You can also control the sweetness and strength of this oat café latte.

Make it once, and even if you are not a big fan of oat milk, there are high chances that it will become your instant favorite.

I can say this with confidence, because I have personally seen haters converting into lovers with this oat milk latte. So are you ready to make it for yourself?

Ingredients

Oat milk: As the name suggests, this is the main ingredient of this latte coffee. It creates a smooth and creamy iced oat latte base, just like a barista-style oat milk latte. Oat milk works best for a richer texture. For a variation, you can also use soy milk, almond milk, or even dairy milk.
Ice cubes: They are needed to keep the drink cold and help maintain the layered presentation.
Instant coffee: Another essential ingredient for making dalgona coffee. Instant coffee is best to make thick, stable foam. You can use any instant coffee of your choice here.
Sweetener: To add sweetness and help stabilize the whipped coffee, I used brown sugar. You can use any other sweetener of your taste preference.
Hot water: It helps dissolve and whip the coffee mixture properly into a whipped cream-like texture.
Cinnamon powder (optional): It is an optional ingredient, but highly recommended as it adds a subtle warm flavor that complements the taste of oat milk.

How to Make Iced Oat Latte with Dalgona Coffee

Making this drink takes only 5 minutes.
To make this brown sugar oat milk latte, prepare a tall glass by filling it with ice cubes * to keep the drink cold and refreshing.
Then make the oat milk latte base by pouring warm oat milk into a glass along with cinnamon * and frothing it using a milk frother. This creates a smooth iced oat latte base. Pour it * over the ice.
Now, whip the dalgona coffee in a small glass or a bowl. In a small glass, combine instant * coffee, brown sugar, and hot water. Whisk using a milk frother or a hand whisk until thick, * creamy, and fluffy with soft peaks. To check if it is ready, flip the glass and if it * stays, it is ready. The mixture should hold its shape when lifted. That’s when it’s ready.
To assemble the drink, pour or spoon the whipped coffee over the oat milk, letting it sit * on top to create a layered effect.
Sprinkle cinnamon if desired and stir before drinking to combine the creamy foam with the * oat milk. That’s it.

Variations

Vanilla Iced Oat Latte

Love vanilla-flavored coffee drinks? Then make a vanilla version by adding a few drops of vanilla extract or vanilla bean paste to the oat milk. This will add a soft bakery-style and subtly sweet flavor.

Mocha Iced Oat Latte

Mix a little mild cocoa powder or melted chocolate into the oat milk for a light mocha-style version.

Caramel Iced Oat Latte with Dalgona

If you like iced caramel latte, then add a drizzle of caramel sauce to the glass before pouring oat milk. This makes a rich, dessert-style iced oat latte with more sweetness.

Maple Cinnamon Iced Oat Latte

Don’t like using sugar in coffee? Then feel free to swap sugar with maple syrup. Maple syrup and cinnamon give this oat latte a warm, cozy flavor that pairs beautifully with coffee.

Protein Iced Oat Latte

Want a protein boost in your coffee? Blend oat milk with a scoop of vanilla or unflavored protein powder for a more filling version that still tastes creamy and smooth.

Coconut Iced Oat Latte

If you are a fan of tropical flavors, then replace part of the oat milk with coconut milk for a slightly tropical flavor and a richer texture.

Hazelnut Iced Oat Latte

Add a few drops of hazelnut syrup or extract to add a nutty, café-style flavored iced oat latte.

Cold Brew Oat Latte

Instead of whipped coffee, use cold brew coffee in the base instead of whipped dalgona for a more iced coffee-like experience.

Spiced Chai Oat Latte Twist

Enjoy chai latte? Then instead of just cinnamon, add a pinch of chai spice to the oat milk for a subtle masala chai variation.

Serving Suggestions

Serve it immediately for the best foam texture and layering. For brunch, pair it with chocolate chip cookies, biscotti, or any light snacks like date snickers.

You can enjoy it as a refreshing afternoon drink, breakfast coffee, or coffee treat any time of the day.

The iced latte version is perfect for warm days when you want a café-style iced oat latte at home.

Storage Suggestions

It is best enjoyed fresh for maximum foam and texture.

If you want to store it for some time, then you can store the whipped coffee for a few hours and re-whip it before use. You can also freeze the whipped coffee for frozen dalgona.

Just avoid storing the assembled drink as the foam will deflate when stored.

Tips & Tricks to Make the Best Oat Milk Latte

Coffee: For this dalgona version, use instant coffee only, as it whips into a stable foamy texture unlike regular brewed coffee.
Sugar: Sugar stabilizes the foam and helps create thick, glossy peaks. I used brown sugar in this recipe, but you can also use regular granulated sugar, muscovado sugar, coconut sugar, or date sugar.
Water: Hot water is required in this recipe to dissolve the mixture quickly and improve whipping results.
Whipping: You can use a milk frother, electric mixer, or just a whisk. But remember to whisk continuously to achieve light and airy foam faster.
Consistency: It should be whipped until soft to medium peaks form that hold their shape.
Oat milk: For this recipe, I recommend barista-style oat milk for a richer and creamier iced oat latte texture. But you can also use regular oat milk, which works well too.
Ice Cubes: Use enough ice to maintain layers and keep the drink chilled longer.
Sweetness: Feel free to adjust sugar to taste, but avoid reducing too much or the foam may not form properly. A 1:1 ratio works best.
Flavoring: I added some ground cinnamon to the oat milk for a sweet, aromatic boost. You can also add a few drops of vanilla extract.
Serving: Stir the drink just before drinking to blend the whipped coffee with the oat milk evenly.
