Oat milk lattes have become the most popular dairy-free coffee drink in specialty cafés — and for good reason. Oat milk is naturally sweet, froths beautifully, and complements espresso in a way that no other plant milk quite matches. Here's how to make a café-quality oat milk latte at home.

Why Oat Milk Works So Well in Lattes

Oat milk has a naturally creamy texture and mild sweetness that pairs beautifully with espresso. Unlike almond milk (which can curdle) or coconut milk (which can overpower), oat milk enhances the coffee's flavor without competing with it. Barista-edition oat milk is specifically formulated to froth like whole milk — producing silky microfoam ideal for latte art.

What You'll Need

  • 2 shots of espresso (60ml)
  • 150–200ml barista-edition oat milk
  • A milk frother or steam wand
  • Your favorite latte mug (250–300ml)

For the espresso base, use the Blueprint Coffee Penrose Espresso Blend — its natural sweetness and balanced body pair perfectly with oat milk's creamy character. Grind fresh with the 1Zpresso K-Ultra Manual Coffee Grinder for the best extraction.

Step-by-Step: Hot Oat Milk Latte

Step 1: Pull Your Espresso

Brew two shots of espresso into your preheated mug. A double shot (60ml) is the standard base for a latte — strong enough to shine through the milk without being lost.

Step 2: Steam Your Oat Milk

Pour 150–200ml of cold barista oat milk into your steaming pitcher. Steam to 60–65°C using your steam wand — introduce air in the first few seconds (the "stretching" phase) then submerge the wand to create a whirlpool (the "texturing" phase). The result should be silky, glossy microfoam with no large bubbles.

No steam wand? Use a handheld electric frother: froth cold oat milk for 20–30 seconds, then microwave for 45–60 seconds. The result is excellent microfoam without any special equipment.

Step 3: Pour and Finish

Tap your pitcher on the counter and swirl to integrate the foam. Pour the steamed oat milk over your espresso in a slow, steady stream, starting from a height to sink the foam, then lowering the pitcher to let the foam float on top. For latte art, tilt the cup slightly and pour in a gentle side-to-side motion as you finish.

Iced Oat Milk Latte

  1. Fill a tall glass with ice
  2. Pour 150–200ml of cold oat milk over the ice
  3. Pull two shots of espresso and pour slowly over the milk
  4. Stir gently or leave layered for a beautiful presentation
  5. Add vanilla syrup if desired

Choosing the Right Oat Milk

  • Barista edition — always choose this for lattes. It's formulated with extra fat and stabilizers for better frothing and won't separate when mixed with hot espresso.
  • Original/regular — fine for iced drinks but may separate or produce thin foam when steamed.
  • Low-fat or "light" — avoid for lattes; produces watery foam with poor texture.

Flavor Variations

  • Vanilla Oat Latte — add 1 tbsp vanilla syrup to the espresso before adding milk
  • Brown Sugar Oat Latte — stir brown sugar syrup into the espresso; top with cinnamon
  • Hazelnut Oat Latte — add hazelnut syrup for a nutty, warming flavor
  • Oat Milk Mocha — add chocolate sauce to the espresso base before steaming

Pair your oat milk latte with a Cooper Street Chocolate Biscotti for the perfect café-at-home experience. ☕
