A Slice of Summer: Fresh Watermelon Cake for Kids!
Slice into summer with a watermelon treat table that’s fresh, fruity and bursting with colour! Thick rounds of juicy watermelon are topped with creamy vanilla yoghurt, strawberries, raspberries, blueberries, cherries and passionfruit to create colourful watermelon cakes made for sunny-day celebrations.
With no baking required, these fruity little cakes are wonderfully simple to prepare and make a refreshing addition to a summer party or watermelon-themed snack table. Leave the bright green rind on for that classic watermelon look, or remove it to create vibrant red cakes piled high with berries and swirls of whipped cream.
Keep the juicy fun flowing with homemade melonade, a refreshing mix of watermelon and lemonade served straight from hollowed-out watermelon drink dispensers. Add watermelon-shaped cups, oversized paper straws and plenty of pink and green details for a self-serve drink station that’s almost as much fun to look at as it is to sip!
So grab your watermelons, chill the melonade and get ready to serve up a delicious slice of summer fun!

Make Your Watermelon Cakes
Serve up a sweet slice of summer with these colourful watermelon cakes! Thick rounds of juicy watermelon are topped with creamy vanilla yoghurt and piles of fresh berries for an easy no-bake treat that’s bursting with fresh summer flavour.
What You’ll Need:
- Whole watermelons
- Vanilla yoghurt
- Strawberries
- Raspberries
- Blueberries
- Cherries
- Passionfruit
- Whipped cream
- Cake stands or serving platters
- Sharp knife
💡 Tip: Confident with your knife skills? Cut the watermelon into thinner rounds to create fun watermelon pizzas instead of cakes!
Steps:
Step 1. Slice Your Watermelon
Cut the watermelon crosswise into thick, even rounds. Keep the slices chunky enough to hold their shape once the toppings are added. You can leave the rind on some cakes for a bold green edge or carefully slice it away for a completely different look.
Step 2. Add the Vanilla Yoghurt
Spread a generous layer of creamy vanilla yoghurt across the top of each watermelon round, leaving a little of the red watermelon showing around the edge.
Step 3. Add the Fruity Toppings
Now for the colourful part! Top the cakes with a mix of:
- Sliced strawberries
- Fresh raspberries
- Blueberries
- Cherries
- Passionfruit pulp
Step 4. Finish With Whipped Cream
Add a swirl of whipped cream just before serving for an extra-special cake-shop finish. For the party table, wrap whipped cream containers in watermelon-patterned paper to make them part of the colourful display.
💡 Tip: Keep the yoghurt, fruit and whipped cream chilled until you’re ready to decorate. Watermelon is at its best when everything is cold, crisp and refreshing.
Mix Up Refreshing Melonade
Keep the summer fun flowing with refreshing watermelon melonade! A fruity mix of fresh watermelon and zesty lemonade is served straight from hollowed-out watermelons for a sweet sip.
What You’ll Need:
- Whole watermelons
- Lemonade
- Watermelon flesh
- Keg drink dispenser taps
- Watermelon-shaped cups
- Large paper straws
- Blender
- Strainer
Steps:
Step 1. Hollow Out Your Watermelons
Carefully cut the top from each watermelon and scoop out the flesh, saving it to make your melonade. Fit a drink dispenser tap securely into the side of each hollowed-out watermelon.
Step 2. Make Your Melonade
Blend the watermelon flesh until smooth, then strain to remove the pulp if desired. Mix with chilled lemonade until you have the perfect balance of sweet watermelon and zesty lemon.
Step 3. Fill Your Watermelon Dispensers
Pour the chilled melonade into the hollowed-out watermelons and pop the tops back on to complete the look.
Step 4. Pour and Enjoy
Let kids pour their melonade straight from the watermelon taps into watermelon-shaped cups and finish with oversized paper straws for an extra splash of fruity fun!
💡 Tip: Make extra melonade and keep it chilled in the fridge so you can quickly refill your watermelon dispensers throughout the party.

Watermelon Cake FAQs
Can I make the watermelon cakes ahead of time?
Yes! Cut the watermelon rounds ahead of time and keep them covered and refrigerated. For the freshest result, wait until shortly before serving to add the yoghurt, berries, passionfruit and whipped cream.
Should I leave the rind on the watermelon cake?
Either works! Leaving the rind on creates a fun, instantly recognisable watermelon look and makes the slices easier to handle. Removing the rind creates a cleaner cake-style finish and lets that brilliant watermelon-red colour become the star.
What yoghurt works best for watermelon cake?
A thick vanilla yoghurt works beautifully because it’s creamy, slightly sweet and easier to spread without immediately running off the watermelon. Greek-style vanilla yoghurt is another great option if you want an even thicker topping.
What fruit can I put on watermelon cake?
Strawberries, raspberries, blueberries, cherries and passionfruit create a gorgeous mix of colours, flavours and textures. You can also experiment with kiwi fruit, grapes, blackberries, mango or whatever fresh summer fruit your kids love.
Can I get matching party items?
Absolutely! Keep the watermelon fun flowing with matching party pieces designed to bring the whole celebration together.
