Tips for the best results
Make the brown sugar syrup ahead and keep it in the fridge so your latte comes together in seconds. Use strong coffee or espresso so it doesn't taste watered down over ice, and a pinch of cinnamon in the syrup adds warmth. Shake the syrup with the espresso for a frothy finish.

Frequently asked questions
No espresso machine? Strong brewed coffee, a moka pot, or even instant espresso dissolved in a little hot water all work well.
How long does the syrup keep? Store it in a jar in the fridge for up to 2 weeks — it's great in coffee, oatmeal, or cocktails too.
Can I make it hot? Yes — skip the ice, warm the oat milk, and stir everything together for a cozy version.
