What is cold foam and how do you make it?
Cold foam is aerated heavy cream and brown sugar syrup whipped until fluffy. Use an electric milk frother or whisk vigorously until stiff peaks form, then top the drink immediately.
Can you make this drink ahead of time?
Prepare the espresso, oat milk, and caramel base ahead and refrigerate. Make the cold foam fresh just before serving for the best texture.
What's the difference between this and a store-bought brown sugar drink?
Homemade versions let you control sweetness and skip artificial syrups. The cold foam topping is richer and fluffier than mass-produced foam.
Can I use regular milk instead of oat milk?
Yes. Whole milk, 2% milk, or any plant-based alternative works. Oat milk adds a naturally sweet, creamy flavor that pairs well with brown sugar.
How do you get the foam to stay on top?
Pour the drink first, then spoon the freshly whipped foam over the surface. Serve immediately—cold foam is best enjoyed within a few minutes.
