Frequently Asked Questions
Can I make the syrup ahead?
Yes — store brown sugar syrup in an airtight jar in the fridge for up to 2 weeks.
Can I use other milk?
Absolutely — almond, soy, or coconut milk all work, but oat milk gives the creamiest texture.
Can I make it hot instead?
Yes — skip the ice, steam the oat milk, and pour the syrup and espresso together for a hot version.
Can I make it less sweet?
Use 1–2 tablespoons of syrup instead of the full amount and adjust to taste.
