Start by filling your glass with ice cubes to keep your drink cold and slow ice melting, which improves the drink's texture.

Pour 3 tablespoons of strawberry syrup over the ice. The syrup will sink to the bottom, and we'll mix it later. The deep red color looks pretty as it swirls.

Next, pour ¾ cup of cold oat milk into the glass over the ice to help avoid splashes and create a nice marbled look. Use a long spoon to gently mix the strawberry syrup into the oat milk.

The drink will turn soft and milky pink. Stir three or four times to blend it without melting the ice.

In a small container, mix ¼ cup of cold oat milk with a little vanilla syrup. Use an electric whisk or shake it in a sealed jar until it's thick and frothy.

The foam should hold its shape but pour easily. Spoon or pour the cold foam over your drink to create a dome shape above the rim. The white foam on the pink drink looks nice and is great for photos.

Add a reusable straw or sip straight from the glass. The first sip gives you cold foam, and then you'll taste the strawberry-oat mixture. Stir the foam into the drink as you enjoy it; it makes a big difference.
