Description
A creamy, refreshing iced oat milk latte made in just five minutes, perfect for a quick vegan treat.
Ingredients
- 2 oz (60 ml) espresso, brewed fresh
- 2 teaspoons (8 g) brown sugar
- Oat milk, unsweetened, enough to fill glass ¾ full
- Ice cubes, as needed
- Cinnamon, for garnish (optional)
- Nutmeg, for garnish (optional)
Instructions
- Step 1: Start by brewing a double shot of espresso using your espresso machine. Aim for rich, bold espresso preferably with crema on top.
- Step 2: Add two teaspoons of brown sugar directly into the hot espresso. Stir until the sugar completely dissolves to avoid any gritty texture.
- Step 3: Take a tall glass or jar and fill it with ice cubes up to three-quarters full. This allows enough room for milk and espresso without overflowing.
- Step 4: Shake the oat milk carton briskly for 3-5 seconds to mix contents without creating froth.
- Step 5: Pour the oat milk carefully over the ice. Gently add the espresso on top by pouring slowly to maintain distinct layers in the glass.
- Step 6: Sprinkle a pinch of cinnamon or nutmeg over the latte if you prefer an aromatic twist.
- Step 7: Add a reusable straw and serve immediately to enjoy your iced oat milk latte.

Ingredient Notes
- Oat milk: Use unsweetened oat milk for a creamy base. It blends well and adds a subtle sweetness to your latte without overpowering other flavors.
- Espresso: A good shot of quality espresso brings that rich flavor. If you don’t have espresso, strong brewed coffee works as a decent substitute.
- Sweetener: Choose a sweetener you love, maple syrup or agave syrup are great choices for a hint of natural sweetness. Adjust to taste based on your preference!
- Ice cubes: Use fresh ice cubes for the best texture. Avoid using ice that’s been sitting around, as it can dilute your drink and affect the flavor.
- Optional flavor syrups: If you want to add an extra kick, flavored syrups like vanilla or hazelnut can elevate your latte’s profile. Just a splash can make a big difference!
Recipe Tips
- If your espresso isn’t very strong, brew 2 ounces using a fine coffee grind for a more robust flavor.
- When the brown sugar doesn’t dissolve, mix 2 teaspoons into the espresso while it’s still hot for quicker blending.
- For a watery latte, fill ¾ of the glass with ice before pouring in the oat milk and espresso.
- If ice dilutes your drink too fast, try using coffee ice cubes for freezing brewed coffee into cubes in advance.
- When looking to customize, add a sprinkle of cinnamon or nutmeg; a pinch goes well with the oat milk iced latte flavors.
Serving Suggestions
Serve with a slice of gluten-free banana bread or almond flour muffins. Pair with a fresh fruit salad or avocado toast.
Use to make oat milk iced latte smoothies or blended coffee desserts. Add to overnight oats or chia pudding for a coffee twist.
Top with a sprinkle of cinnamon or drizzle of nut butter. Add a dollop of whipped coconut cream or dairy-free whipped topping for richness.
Recipe variations
- You can use cold brew coffee instead of espresso for a smoother flavor in your oat milk iced latte. Add two teaspoons of brown sugar for sweetness and stir well.
- Add cinnamon or nutmeg to the latte for a subtle spice note. Use ¼ teaspoon of your preferred spice. Either ground or whole spices can be used for infusion.
- Either oat milk or almond milk can be used as the non-dairy base in the iced latte. Use ¾ cup of milk and ice to fill the glass accordingly.
- If making multiple servings, double or triple the espresso shots and brown sugar amounts. For three lattes, use 6 oz espresso and 6 teaspoons brown sugar mixed before pouring.
