Watermelon Milkshake (2 Ingredients)

Watermelon milkshake is a drink you’ll want to make all summer. It tastes like a creamy pink cloud.

Every time I make it, my little brother jumps up and down, yelling, “Milkshake time!” Honestly, I don’t blame him.

Once, he even asked for a slice of watermelon in his lunchbox instead of cookies!

The shake is so good and easy, you’ll feel like a milkshake pro in no time. Ready to blend up this dreamy dessert drink? Let’s get started!

Great for cooling down after a hot day at the beach or pool
No cooking needed – just blend and enjoy!

Ingredients You’ll Need

Fresh watermelon: The star of our shake! Pick a sweet, ripe one for the best flavor. The redder the inside, the sweeter your shake will be.
Vanilla ice cream: Creates that creamy, dreamy texture we all love. The vanilla flavor lets the watermelon shine while adding sweetness.
Whipped cream: Totally optional, but adds a fluffy cloud on top! Who doesn’t love that extra touch of creamy goodness?
Ice cubes: Add a few if you want your milkshake extra cold and thick. Perfect for super hot days!

Equipment You’ll Need

Blender: Any blender works! I’ve made this with fancy ones and cheap ones – they all get the job done.
Sharp knife: Makes cutting watermelon so much easier. A dull knife and watermelon is a slippery disaster waiting to happen!
Measuring cups: Helpful but not critical – I often just eyeball it after making these so many times.
Fun glasses: Tall glasses show off the pretty pink color. My kids love it when I use mason jars with colorful straws.

How to Make Watermelon Milkshake?

This refreshing treat comes together in just minutes! Simply blend, pour, and enjoy this perfect summer cooler.

Step 1: Prep your watermelon. Cut your watermelon into chunks, removing all seeds. For easier blending, aim for 1-inch cubes – I’ve found this size works perfectly.

Step 2: Make watermelon juice. Add 4 cups of watermelon chunks to your blender and pulse until smooth. You’ll have a beautiful, bright pink juice in seconds!

Step 3: Add the ice cream. Add 6 scoops of vanilla ice cream to the watermelon juice. Start with less – you can always add more if you want it creamier!

Step 4: Blend until smooth. Pulse until everything is mixed together. I like to stop once or twice to scrape down the sides for the perfect consistency.

Step 5: Pour and garnish. Fill glasses with your pink creation, top with whipped cream if desired, and add a small watermelon wedge on the rim. So cute!

Tips for the Best Watermelon Milkshake

Use cold ingredients. Pop your watermelon chunks in the fridge for an hour before blending for an extra cold shake without watering it down.
Check for sweetness. Taste your watermelon first! If it’s not super sweet, you might want to add a tiny bit of honey or sugar.
Don’t overblend. Mix just until combined. Overblending can make the shake too thin and melt the ice cream too quickly.
Serve immediately. These shakes are best enjoyed right away while cold and fresh. They don’t store well once mixed.
Go seedless. Save yourself trouble and buy seedless watermelon. I’ve spent way too much time picking out black seeds!

Variations and Substitutions

Make it dairy-free! Use coconut or almond milk ice cream instead. I tried this for my lactose-intolerant niece, and she loved it!
Add berries. Toss in a handful of strawberries or raspberries for extra fruit flavor. This combo has become my weekend favorite.
Try different ice cream flavors. Strawberry or coconut ice cream makes an amazing tropical twist. My wife prefers it with strawberry!
Add lime. A squeeze of fresh lime juice brightens everything up. This tiny change made a huge difference when I discovered it last summer.

Make-Ahead and Storage Tips

Prep watermelon ahead. Cut and store watermelon chunks in the freezer for quick shakes anytime. Game-changer for busy summer days!
Don’t store mixed shakes. Once blended, these are best enjoyed fresh. They separate and lose their texture when stored.
Freeze in popsicle molds. Turn leftover mixture into popsicles! My kids actually beg me to make extra just for this.
Make watermelon juice ahead. Blend just the watermelon and refrigerate the juice for up to 2 days. Then add ice cream when ready.
Use frozen watermelon. Freeze watermelon chunks for an even thicker shake without adding ice, which waters it down. This trick changed my life!

Common Questions

While watermelon provides vitamins and hydration, this treat contains ice cream with added sugar and fat. Enjoy it as an occasional summer indulgence rather than daily nutrition.

Look for a watermelon that feels heavy for its size with a yellow spot (where it sat on the ground). The deeper the yellow, the longer it ripened on the vine!

Yes! Frozen watermelon makes an even thicker, colder shake and means you need less ice cream. I often freeze extra watermelon chunks specifically for shakes.

This recipe makes about 3 generous servings. You can easily double it for a family or cut it in half if you’re just making it for yourself.

Absolutely! Kids love the pretty pink color and sweet taste.
