Paleo Watermelon Cake

No Bake Watermelon Cake Recipe

If you are looking to cut a few calories on cake you’ve gotta try this “Paleo friendly” No Bake Watermelon Cake recipe. I’ve never seen watermelon go so fast in my house! The kids were very excited when they saw this cake!

They acted like it was a birthday party!! I was a bit surprised to see just how excited they were!  It’s made with a homemade whipped cream recipe that was really thick!  Holds up nicely!

I’ve been trying really, really hard to stick to clean eating and it sure does help when you have a beautiful arrangement of fruit that tastes amazing.  One of my main inspirations is the Clean Eating Magazine.  You can get the first 30 days free here on Amazon too!

All you iSavers already know about our No Bake Ice Cream cake recipe and have proven your love for the “No Bake” options but now it’s time to try a healthier no bake cake. I just know you are going to like this one too!

There are many different options you can do with this cake too. For example, you can use Coconut Whipped Cream recipe found here to make it Paleo friendly! Who says you can’t have Cake while on the Paleo Plan?!! You can add different types of fruit to the top of your cake.

I choose to have raspberries and blueberries because those are our family favorites but feel free to experiment or add your own favorites. I added natural almonds to the sides of this no bake watermelon cake recipe but you can add granola too.

Stick with the Almonds if you are Paleo though. Or leave the almonds off altogether if you don’t like them.  I’ve also had friends create mini Watermelon Cupcakes topped with whipped cream!  Cute right?!!

Watermelon Cake made with whipped cream

First we cut our watermelon. We cut the round ends off and carved the cake out of the heart of the watermelon like this:

Next we frosted our watermelon with real whipped cream. (be sure to use coconut whipped cream for the Paleo version though)

Note:  I’ve not used Cool Whip topping so I’m not sure if it would work or not.  The real whipped cream purchased from HEB near the strawberries works great though!

Tip:  Be sure your watermelon is nice and cold when you are frosting it. The whipped cream sticks nicely when it’s cold.

Next I added fresh raspberries and blueberries on top! Then added the sliced almonds on the side. Feel free to add granola to leave it plain too.

Wouldn’t this cake be perfect to make for a Memorial day or 4th of July Party?!!!

Oh and the cake held up nicely in the refrigerator overnight.  When I sliced another piece there was a little bit of water in the bottom of the plate so next time I think I will lay down a paper towel under the watermelon on the plate before I decorate it.  The whipped cream held up nicely overnight too!  For some reason I was thinking it would melt right off but it didn’t!

    1. lol! Nope, no joke. This watermelon cake is intended for low calorie or paleo friendly diets! It’s not for everyone! It would make an awesome joke though!

        I would punch the person that offered me this “cake,” especially on my birthday.

        If you really thinks this “would make an awesome joke,” you are an awful terrible person.

          Gosh that is a mean reply- it is fine if it is not for you but go easy on the person who offered this cake to us- I actually can’t eat gluten and LOVE watermelon and I think it looks like an awesome summer favorite for my family…

          Thanks a ton for posting this Jennifer, I think you are an AWESOME person for doing it and giving us something fun, unusual and delicious to try! Also I looked at several versions, and didn’t want to use the coconut whipped cream but to try regular and so I was really happy to find your version! Keep these cool versions coming- eating fresh is medicine for us all!

          Wow, how rude! I bet you never have a happy birthday anyway if you talk like that. Save your self a police record of assault and not do what you say.

  5. Hi Jennifer,

    Have tried your method to do watermelon cake. It was great though doing first time in my whole life. Freezing the water melon for 15 to 30mins was actually drying the watermelon water in order to have the cream stick to it. I have actually doing it 2 times to get the cream stick to the watermelon.

    The strange thing is that when I whip the cream, as it was hot in the kitchen, I switch on the fan and whip the cream, the cream become sticky in short time. I do not know whether is it due to the quality of the cream or the fan blow towards me causes this. Well, it was fast.

    But it was fun. Would like to learn from you more.

  6. dont understand how to get the whipping cream thick. Don’t use whipping very much at all. Do i whip it with a mixer until it becomes thick. and do i put anything else in it when whipping.

    1. If you whip your whipping cream with a whisk by hand, it will not run. You can put it on squares, etc and won’t get runny like it does when you use a hand mixer.

    2. I use heavy cream and some sugar and what you do is use a whisk and whisk the cream and sugar together it will start to become thick. Try not to go over board with the sugar. Best of luck:)

    3. Put a small stainless steel bowl in the freezer with the mixer blades and allow them to get chilled. When chilled, take it out and pour the whipping cream in. Mix it non-stop until it’s thick. You can actually turn the bowl upside down and it won’t fall out when it’s thick. Mom always added a little sugar to it, too.

    4. cathy Freeman, use cold heavy whipping cream, COLD metal bowl and COLD beaters. It takes a while, be patient. I would like to try this but I would make it a ONE layer watermelon cake :). I wish these type of sites had a link at the top for printer friendly so I don’t have to copy/paste

  7. I’m going to make this this weekend for Australia Day, am going to try passionfruit yogurt instead of cream. 🙂

    I made 2 of these watermelon cakes for a covered dish dinner. I used seedless watermelon and real whipped cream. Decorated with kiwi, strawberries and raspberries… everyone loved them…. they went very fast.

  9. I made this for a friends birthday yesterday. I missed the part about the watermelon being cold. It heldup well when I put it in the fridge and then in a cooler to take it to the beach for a party. We live in Florida so I did not expect the coconut frosting to last long. It didn’t but everyone still loved it. Thanks for the recipe. I am in a fitness group and today they are all asking for the frosting recipe. Very tasty and a real hit, at the party amongst my health conscious friends.

    1. Mariella, you sure can make this fruit dip 1 8 oz reg or fat free cream cheese to 1 7oz jar of Marshmallo cream. Beat till stiff 🙂 Enjoy

    1. I’m not sure how to answer this one. You can purchase a seedless watermelon. I used a seeded watermelon and the slice I took in the photo just happened to not have seeds in it.

  11. Hey Jennifer, with your permission I would love to feature this blog in a baby shower inspiration slider!

  12. My workout buddy just made this for me for my 31st birthday! We all eat mostly paleo, so the coconut swap was perfect!

    Thanks for sharing!! 🙂

  13. I used cool whip and it worked well. I patted the watermelon with paper-towel before spreading on the cool whip and it stuck just fine. I made it about an hour before serving and it sat on the table looking pretty the whole time.

  14. I used cool whip and it worked really well! I patted the outside of the watermelon with paper towel before I put the cool whip on and it definitely stayed together in the fridge overnight.. Awesome recipe!

  15. Was the whipped cream you used stabilized whipped cream? I think that is the only way it would survive. There are a few ways to do it, one uses unflavored gelatine. I’m sure it’s easy to get the recipe online. Good Luck

    1. I used a very thick “real” whipped cream recipe. It doesn’t have to be the stabilized one but it will help if you plan to keep it out of the refrigerator for a while. I wouldn’t suggest using cool whip because it’s just not thick enough to spread on the cake. It has to be the real whipped cream.

  16. Heb??? What does that mean? I really want to make this tomorrow for fathers day. Help needed with whip cream.

    1. I have not tried cool whip. I have tried the real whipped cream that HEB makes and it works. I think it works because it’s really thick. My first thought on cool whip is that it’s creamy and not so thick and you really need it to be thick to be able to stick to the watermelon. Has anyone else tried cool whip? Please leave a comment if you have.

  17. Ok, I tried this with the whipped cream in a can that you spray out and it didn’t stick to the watermelon, it just slid down the sides. Then I went to the store to get whipped cream in a container and that didn’t work either. I’m having no luck finding the right whipped cream. This looks like such a tasty idea I really wanted it to work. we ended up just cutting the watermelon and then putting dabs of whipped cream and other fruit on top.

    1. I have not tried the whipped cream in a can. Make sure you watermelon is nice and cold. I think this makes the world of difference. Also, pat down your watermelon with a papertowel before you start.
