Iced Oat Milk Latte

Smooth creamy and just sweet enough this iced oat milk latte is my go-to for a cooling pick-me-up that feels like a coffee shop treat but takes five minutes in my own kitchen. Whether you need a morning wake-up or an afternoon pause this simple drink never disappoints.

I started making these when my kids wanted fancy lattes on hot days but I did not want to haul everyone to the café and now it is a summer staple

Ingredients

• Espresso or strong brewed coffee: gives the drink its signature bold taste use freshly cooled shots for smoothest results
• Chilled oat milk: adds creamy sweetness and a velvety texture look for barista-style milks for best froth
• Sweetener like maple syrup or simple syrup: adds a hint of indulgence choose pure maple syrup for warmth or simple syrup for a neutral sweetness
• Ice cubes: keep your latte cold and refreshing opt for filtered ice for best appearance and taste

Instructions

Fill the Glass with Ice:

Add enough ice cubes to fill a tall glass almost to the top. This keeps your drink chilled and prevents it from getting watered down too quickly.

Pour the Coffee Over Ice:

Carefully pour the cooled espresso or strong brewed coffee over the ice. The coffee should be at room temperature or just slightly warm to avoid melting the ice right away.

Add the Oat Milk:

Slowly pour in the chilled oat milk. Doing this after the coffee makes for beautiful swirls and ensures an even mix.

Sweeten if Desired:

If you like a bit of sweetness add the maple syrup or simple syrup at this stage. Start with one teaspoon then taste and adjust if you prefer it a little sweeter.

Mix and Sip:

Use a spoon or straw to stir the drink well until everything is fully combined and serve immediately. Enjoy your homemade iced oat milk latte at its frothiest.

Oat milk is my favorite for its creamy feel and subtle flavor—it pairs so well with bold espresso I still remember the first time I tried it at a local café in summer and how it instantly became the drink I craved all June long

Storage Tips

Iced oat milk lattes taste best fresh but if you want to prep ahead you can brew your coffee and chill it in the fridge for up to two days. Store oat milk cold and only assemble drinks when ready to serve—otherwise the ice will melt and dilute the flavor. Pre-mixing with ice is not recommended unless you like a softer milky coffee.

Ingredient Substitutions

If you do not have oat milk try almond soy or coconut milk—each brings its unique creaminess. Maple syrup can be swapped for agave or honey if you are not vegan or leave it out for a less sweet drink. For the coffee base strong cold brew or instant espresso powder work in a pinch.

Serving Suggestions

Garnish with a sprinkle of cinnamon or cocoa powder for a café touch. For a layered effect pour milk slowly over the back of a spoon. Pairs beautifully with a homemade biscotti or a simple granola bar for an energizing snack.

Cultural and Seasonal Notes

Iced coffee drinks have a long history around the world—from Greek frappé to Vietnamese cà phê sữa đá. Switching to oat milk brings a new-school twist that is both sustainable and delicious. In the cooler months use the same ingredients for a hot oat milk latte or add a dash of nutmeg for holiday vibes.

Seasonal Adaptations: Use pumpkin spice for an autumn-inspired treat add fresh mint or berries for a summer refresh or try a hint of vanilla or orange zest in spring. For freezer meal conversion make double-strength coffee and freeze it in cubes for a quick grab-and-go latte.
