📖 Recipe

Watermelon milk is a refreshing fruit milk drink that's especially popular in Taiwan, where it's enjoyed during the hot summer months. You can also find packaged watermelon milk in Korean convenience stores and Asian grocery stores.

I love enjoying this beverage during the summer when watermelon is at its peak from June to August. It's one of my favorite ways to cool down on a hot day!

When I make this at home, I use fully ripe watermelon for its natural sweetness so I don't need to add much sweetener. I also blend chilled watermelon with cold oat milk so the drink is refreshing right out of the blender without needing ice.

Ingredients & Substitutes

Exact ingredient measurements are in the recipe card below.

Seedless Watermelon: Choose a sweet, ripe watermelon for the best flavor. Look for a creamy yellow field spot and a melon that feels heavy for its size. Chill before blending.
Plain Oat Milk: I prefer oat milk for its mild, creamy flavor. Unsweetened or sweetened oat milk both work. Plain almond milk or another mild-flavored plant-based milk also works. Avoid coconut milk because its flavor can overpower the watermelon. I also recommend avoiding dairy milk because it may curdle when mixed with fresh watermelon.
Maple Syrup: Honey or another liquid sweetener also works. If using sweetened oat milk, blend the drink first, then add maple syrup to taste.

Expert Tips

Chill the watermelon and oat milk before blending for a refreshing drink without diluting it with ice.
Remove the green skin and white rind before blending, using only the red watermelon flesh for the best flavor.
Use a high-powered blender for a smoother drink with fewer noticeable watermelon fibers.
Strain through a fine-mesh sieve if you prefer a smoother drink without watermelon pulp.

Instructions

Here's how to make watermelon milk:

Blend the ingredients: Add chilled, cubed watermelon and cold oat milk to a high-powered blender. Blend on high until smooth.
Sweeten and serve: Taste and add maple syrup as needed. Blend briefly to combine, then pour into two tall glasses and serve immediately.

Storage

Refrigerator: Store leftover watermelon milk in an airtight container in the fridge for up to 2 days. Stir well before serving, as natural separation may occur.
Freezer: I don't recommend freezing watermelon milk, as thawing can make the texture watery and grainy.

What to Serve With

Japanese Strawberry Sando: A creamy fruit sandwich that complements the refreshing drink.
Egg Salad Sandwich: A savory, creamy sandwich that balances the sweet watermelon flavor.
Butter Cookies: Crisp, buttery cookies that contrast with the smooth, fruity milk.

FAQ

Why is my watermelon milk separating?

Natural separation is normal because watermelon contains a lot of water. Simply stir or shake the drink before enjoying.

Can I use regular milk instead of oat milk?

Yes, but I recommend oat milk because dairy milk can curdle when mixed with fresh watermelon. If using regular milk, keep both ingredients cold, blend just before serving, and drink immediately.

Can I make watermelon milk without a blender?

Yes, you can use a food processor to blend the ingredients until smooth. Alternatively, mash the watermelon with a fork, strain through a fine-mesh sieve, and mix the juice with oat milk and maple syrup.
