This Strawberry Jello Cake has to be one of our all-time favorite desserts made with yellow cake, strawberry mousse and a beautiful mirror glaze. It’s perfect for holidays like Mother’s Day, Valentine’s Day, birthdays or a party!
This strawberry jello cake video was one of our biggest Facebook videos ever with more than 15 million views! It’s a showstopper that you can make up to a day ahead for a celebration.
Serve it standalone or with fresh berries and whipped cream on the side. The jello makes it easy to serve, since the pieces can easily be lifted out of the pan with any rigid spatula. It’s one of my favorite strawberry jello desserts along with Strawberry Pretzel Salad and Strawberry Poke Cake.

You make this cake with three layers inside a rectangular baking dish. The bottom layer is a simple fluffy sponge cake (you can use store bought cake mix or make your own).
The middle layer is an easy strawberry filling made with whipped cream and strawberry jello. Halved strawberries go on the top along with a strawberry jello glaze.
How to Make Strawberry Jello Cake
Start this recipe by making the bottom yellow cake layer. You can use a cake mix, although you’ll only need half of the box to get a one-inch layer.
If you prefer homemade, simply beat 4 eggs with a 1/2 cup of sugar for about 5 minutes to get it fluffy. Then fold in a 1/2 cup of flour until blended…
While the cake is baking, you can make the jello filling. If you want to use natural jello or agar agar, Simply Delish Strawberry Jel works well as a direct substitute for the jello powder. Just note the package sizes are different than jello, so get the same number of ounces.
Let the jello set while the cake bakes and then cools. When you mix the jello with whipped cream, the jello can still be liquid or soft setting, meaning it has a slight jiggle and running a spoon creates streaks through it.
Whisk it together with whipped cream and you will get light-pink colored filling, then you’ll be ready to pour it on top of the cooled cake.
You can put halved strawberries on the filling for a beautiful presentation, and raspberries are a great substitute here too. If your filling is too liquid to hold the strawberries, simply chill for 10-15 minutes and you’ll be good to go.
Depending on how big they are, you can fit about 20 berries in about a 4×5 pattern across the top. Then chill for an hour or more for the filling to set.
After the filling has set, you’re ready to add the mirror glaze. Make more strawberry jello the same way as for the filling, and let it cool to room temperature.
If you’re in a hurry, put your bowl of jello in an ice water bath for 5-10 minutes and stir a few times and it’ll be ready.
It’s best to pour the jello glaze over the back of a spoon, which helps it to dribble and avoid penetrating your filling. It’s fine to dribble onto the strawberries as well as the filling…
Once the mirror glaze is on, carefully place the entire dish into the fridge to chill for one more hour. Then you’re ready to serve!
You can make this cake up to two days in advance, as it keeps nicely in the fridge covered in plastic wrap.

This Strawberry Jello Cake has to be one of our all-time favorite desserts... made with yellow cake, strawberry mousse and a beautiful mirror glaze. It's perfect for holidays like Mother's Day, Valentine's Day, birthdays or a party!
Ingredients
Cake
- 1/2 15-oz box yellow cake mix or white cake mix, see note
- half of ingredients on cake mix box eggs, oil, water etc
Strawberry Mousse
- 6 oz strawberry jello powder two small boxes
- 2 cups boiling water
- 1 cup cold water
- 3 cups whipped cream or cool whip, about 8 oz, see note
Mirror Glaze
- 10 fresh strawberries halved
- 3 oz strawberry jello powder
- 1 cup boiling water
- 1/2 cup cold water
Instructions
Cake
- Preheat oven to 350°F. Grease the bottom of a 13x9 inch glass baking dish and set aside.
- In a medium bowl, prepare the cake batter according to the instructions on the box. [If you prefer a homemade version, see note below]
- Pour cake batter evenly into the prepared pan. Bake for 15-20 minutes until golden and puffy.
- Remove from the oven and cool in the pan at least 30 minutes. Meanwhile, make the strawberry mousse.
Strawberry Mousse
- In a medium bowl, add 6 oz strawberry jello and 2 cups of boiling water. Stir slowly for one minute to dissolve.
Stir in 1 cup of cold water and set aside until half set (THICK BUT NOT FIRM). It takes about over 1 hour at room temperature or 5-10 minutes in the fridge. It's important to wait until it's half set, otherwise, your whipped cream and jello will separate when the mixture cools down.
Add the whipped cream/cool whip to the jello and mix until smooth. The mixture should be quite thick.
- Once the cake is cool, spread the filling evenly across the cake using a spatula. Rap the pan on the counter a few times to level the filling and remove any trapped air.
- Chill for at least 1 hour on a level surface in your fridge. Meanwhile, make the mirror glaze.
Mirror Glaze
- In a medium bowl, combine 3 oz jello powder with 1 cup boiling water and stir slowly for one minute until dissolved. Stir in ½ cup cold water and set aside to cool.
- Remove the cake from the fridge. Arrange strawberry halves on top of the filling, approx. 4 widthwise by 5 lengthwise.
- Once the jello is lukewarm, carefully pour it over the back of a spoon, dribbling across the top of the filling surface and over the strawberries.
- Chill one more hour to allow the glaze to set. Congratulations, you're done - enjoy!
Recipe Tips
-To make a yellow cake from scratch: In a medium bowl, beat 4 eggs and 1/2 cup white sugar for 5 minutes until fluffy; then fold in 1/2 cup all purpose flour until blended. -If you are planning to whip your own cream, it takes 1 1/2 cups of liquid whipping cream to make 3 cups whipped cream.

Made it last night and everybody loved it ! thanks
Why only 1/2 cake mix ?
Hi Robin, that’s to avoid having too thick of a cake layer… 1/2 box makes the cake layer about the same height as the jello cream layer, which is what you want 🙂
Is there no butter in the homemade cake mix ?
Hi Symone, Great question, it’s a yellow genoise-style cake made with eggs, sugar and flour. Try it and you’ll be amazed how easy it is 🙂
wHAT ABOUT USING A STRAWBERRY CAKE INSTEAD OF YELLO OR WHITE? SEEMS LIKE WHAT DO YOU THINK?
Sue that would be fine – any cake mix will work for this recipe 🙂
I want to make this for my daughters bday tomorrow. In glad I tried to make it beforehand. Any tips on how to make it work? Did you use whipped whipping cream or cool whip? She REALLY wants this cake for her bday.
Why did my cake float to the top when I poured in whipped cream jello mix? I whipped whipping cream to stiff peaks. Any tips?
Hi Rox, Thanks for your question and sorry you had trouble before your daughter’s birthday 🙁 So the cake should definitely not detach from the pan! Did you allow the jello to soft set before mixing in the whipped cream? It should form a thick pudding-like consistency that sits nicely on top of the cake… Make sure you watch the video to get an idea if you haven’t already. lmk if you have more questions.
hey i tried this out but my moose didn’t work out as i hoped the whipped cream and jelly separated. i would love to know why this happened
Hi Jenny, Sorry it didn’t turn out and thanks for your question. It separated because the strawberry jello hadn’t reached the “soft-set” stage, which is slightly jiggly, and/or the whipped cream was too soft. To bind together, they both need to be at that consistency. Hope you’ll try again!
i made this the other day shared with my friends and neighbors they said it’s a keeper fantastic turned out great can we use different filling such as blueberries or mixed berries thank you
Hi Beatrice, Thanks so much for your feedback and glad it turned out great! Love the mixed berry combo 🙂
Any ideas why when adding the cooled hello mix to the whipped cream it’s not smooth but like the cream has conjealed? I waited until it was cool enough to mix in?
Hi there ! What is the reason when I put the jello with mouse it soak in my sponge cake? ?
Hi Armine, you need to let the jello half set before mixing with the whipped cream. When it’s nice and thick, it won’t soak into your cake. Hope it helps.
I was wondering if there is a way to make this in a round cheesecake pan, if so what size would you recommend? 9 or 10″
Hi Lucy, Thanks for your question. I wouldn’t recommend a round pan because it’d be difficult to cut and serve, plus the proportions would be off. A rectangular pan is far better. Hope that helps 🙂
