Oat milk and honey were made for each other, and cinnamon ties them together. This is the drink we make most often when it's cold out — sweet without being cloying, and rich enough to feel like a treat without a pile of syrup in it.
It takes about three minutes. The only step people get wrong is the milk, and there's a fix for that below.
The recipe
Makes one 12oz latte · 3 minutes
Ingredients
- 2 shots espresso (or ½ cup strong brewed coffee)
- 1 cup oat milk — barista edition if you can get it (see below)
- 1 tbsp honey, or maple syrup to keep it vegan
- ¼ tsp ground cinnamon, plus a little for the top
- ½ tsp vanilla extract
- Optional: a pinch of nutmeg
Instructions
- Stir the honey into the hot espresso first. This is the step that matters most and the one every version of this recipe gets wrong. Honey doesn't dissolve properly in warm milk — it sinks and sits at the bottom of the mug. Two shots of fresh espresso are hot enough to take it into solution immediately.
- Add the cinnamon and vanilla to the same cup and stir. Ground cinnamon won't dissolve, but suspending it in the espresso keeps it from clumping on the surface of the milk later.
- Heat the oat milk to about 60°C / 140°F. Steam wand, frother, or a saucepan — all work. Do not let it boil. Oat milk splits and turns thin and chalky above roughly 70°C, and once it's split there's no recovering it.
- Froth it. If you're using a steam wand, keep the tip just under the surface for the first three or four seconds to introduce air, then drop it deeper to spin the milk smooth. Aim for wet paint, not bubble bath.
- Pour. Start high and slow to let the milk go under the espresso, then drop the pitcher close to the surface at the end to bring the foam through.
- Dust with cinnamon and drink it while it's hot.
The oat milk is the whole game
If your oat milk lattes have ever come out thin, grey, or separated, it's almost certainly the milk rather than your technique.
Ordinary oat milk is built for cereal and cold glasses. It has relatively little fat and no added stabilisers, so under heat and air it thins out instead of building foam, and it curdles on contact with hot coffee — that's the grey flecking you sometimes see at the edge of the cup.
Barista edition oat milk is a different product. It carries more fat and an added acidity regulator, usually dipotassium phosphate, which stops the proteins curdling when they hit espresso. It froths into genuine microfoam and holds it. It costs a dollar or so more per carton and it is the single biggest improvement you can make to this drink.
Two more things that help:
- Start cold. Cold milk gives you a longer window to introduce air before it reaches temperature. Milk that starts at room temperature is already halfway to done.
- Watch your temperature. 60°C is the target. Oat milk has a narrower window than dairy and punishes overshooting far more harshly.
We went through how the different milks behave under steam in which milk is best for frothing and steaming, if you want the fuller comparison.
What you need to make it
You need a way to make strong coffee and a way to heat milk. Everything past that is a refinement.
- Machine: the Breville Barista Express at $699.95 is the usual all-in-one answer — espresso and steam wand in one box. The Bambino Plus at $499.95 does the same job in a smaller footprint if you already have a grinder.
- Grinder: the Turin DF54 at $225 is the cheapest one we'd recommend for espresso, and it transforms what a Barista Express can do versus its built-in burrs. If you want more, the Turin DF64 at $354 is our most-recommended grinder overall.
- Pitcher: the LUCCA Frothing Pitcher at $30. A proper spouted pitcher is the difference between pouring latte art and pouring a puddle.
- Glass: the notNeutral VERO 6oz Cappuccino Glass at $22.50, if you want to see the layers.
No machine? A milk frother and any strong coffee will get you most of the way there. The drink is forgiving — it's the milk temperature that isn't.
Why this combination works
Honey and oat are both sweet in a rounded, low-acid way, and they reinforce rather than compete. Cinnamon adds the aromatic edge that keeps the whole thing from being flat, and vanilla smooths the join between the coffee's bitterness and the honey's sweetness.
It's also less sweet than most café versions of the same idea. One tablespoon of honey in 12 ounces is a fraction of what goes into a flavoured latte off a chain menu, and you can taste the coffee underneath it — which is rather the point of making it yourself.
Frequently asked questions
Can I make this latte without an espresso machine?
Yes. Use half a cup of strong brewed coffee — a Moka pot, AeroPress or a concentrated French press brew all work well. You want something noticeably stronger than regular drip, or the oat milk and honey will bury it entirely.
What if I don't have oat milk?
Whole dairy milk works beautifully and is more forgiving to steam. Almond milk is thinner and prone to splitting; soy sits somewhere in between and froths reasonably well. Whichever you use, look for a barista edition if one exists — the formulation difference matters more than the brand.
Is this drink vegan?
Not with honey. Swap in maple syrup at the same quantity and it is — maple's slight caramel note actually suits the cinnamon well, so it's a genuine alternative rather than a compromise.
Can I prepare the milk without a steam wand?
Yes. A handheld frother, a French press plunger pumped rapidly, or a jar with a tight lid shaken hard for thirty seconds will all produce foam. Heat the milk to about 60°C first — you can't froth it properly once it's too hot, and you can't fix it after it splits.
Can I use pre-ground coffee?
You can, but it goes stale within days of grinding and you'll taste the difference in a drink this simple. A burr grinder is the highest-return purchase in home coffee — our roundup of grinders under $500 covers the options.
Can I make a larger batch?
Scale the espresso, honey and spices directly, but steam the milk in batches no larger than your pitcher is built for — an overfilled pitcher won't froth. For a crowd, make a jug of the espresso-honey-cinnamon base ahead and steam milk to order.
How can I make it sweeter?
Add honey a teaspoon at a time rather than jumping to two tablespoons. Sweetness builds faster than you expect in a drink this size, and once it's over-sweet the coffee disappears completely.
What other spices can I use?
Cardamom is the best of the alternatives — just a pinch, and it turns the drink in a completely different direction. Nutmeg adds warmth, star anise gets interesting with maple syrup, and a small amount of ginger works if you want some heat to it.
