Strawberry Poke Cake Dessert

Every spring, the request that gets sent my way is for this cake. A white cake gets baked, then Jell-O is poured over the holes, and topped with Cool Whip. To make the cake, you bake and cool the cake, poke the holes, and while it is still warm, pour strawberry Jell-O over it, and refrigerate. It’s different and overall an amazing cake. At birthday dinners and potlucks, it is the type of dessert that goes really quickly, and that’s because of the cream, the cold, and the fruit, and how it has the best wobble.

The first time I made this was for my mom’s birthday as she is firmly in the fruit dessert camp rather than chocolate and it instantly became the warm weather gathering favorite. It is super simple and doesn’t require special skills and tastes way better than it has any right to.

What Makes This One a Keeper

• The Jell-O soaks down into the holes while the cake is still warm, so every bite has strawberry flavor all the way through — not just on top
• Using milk instead of water in the cake mix makes the texture noticeably richer and more tender, almost like a bakery cake
• Cool Whip stays stable in the fridge for days, so this is a genuinely good make-ahead dessert
• The whole thing is cold and creamy, which makes it a perfect summer or spring dessert when you don’t want something heavy
• Five ingredients total — cake mix, eggs, oil, strawberry Jell-O, and Cool Whip — and most of those are pantry staples

What to Know Before You Start

Before you start, here are a few things to keep in mind:

You want the Jell-O to go on warm, not hot. Let the cake sit for about 5 minutes after it comes out of the oven. After those 5 minutes, poke the holes, and pour on the Jell-O. If the cake is too hot, it can get gummy, but if it is fully cooled, the Jell-O won’t soak in as well. The warm cake is the sweet spot.

This cake is best if you put it in the fridge for a minimum of 2 hours. Even better, let it be for a whole day before you serve it. The longer the cake sits in the fridge, the better it is. The Jell-O will be perfectly set the cake will be a bit firmer than it was when you put it in, and most importantly, the Cool Whip will no longer be just sitting on top, it will be integrated into the whole cake. Don’t serve it too soon because it will be a mess!

Use a 9×13 pan. This cake is baked in a 9×13, no layer cake style. The flat surface makes the poke-and-pour method so much easier, and you get nice, clean slices.

This cake has a different texture than most other cakes. This is not a cake that is light and fluffy. This cake is moist, and even a bit denser because of the Jell-O. If you’ve never had poke cake, just know it’s supposed to be that way. In some spots it is even pudding-like, which is what people love about it.

Ingredients

The Cake Base

One box of white cake mix will work regardless of brand. If you want to make the cake nicer, use the same amount of milk instead of water when mixing. The texture will be richer and more tender without you needing to add work. I do this all the time now.

Eggs and oil — Whatever the box says. No substitutions needed.

The Poke Filling

Dissolve one 3 oz box of strawberry Jell-O in boiling water. Use the full-sugar version, not the sugar-free. The sugar-free option does not set the same and can make the cake a little soggy. Two cups of boiling water total – dissolve and pour while still liquid but not super hot.

The Topping

Cool Whip — One large tub (16 oz) thawed in the fridge. Please do not use whipped cream from a can. It will deflate quickly and won’t hold up. Cool Whip stays put for days and spreads easily. If you want to get a little fancier, you can fold a little cream cheese into it for a slightly tangier, more stable topping, but the plain version is genuinely good as is.

How to Make Strawberry Poke Cake

Step 1: Bake the Cake

Mix and bake the cake per box instructions in a greased 9×13 pan. If water is being swapped for milk, use the same measurement — just milk instead. for the bake time, you will want to pull the cake out once a toothpick comes out clean and the edges are just starting to pull away from the pan. After you take the cake out, let the cake cool for about 5 minutes. You want to cool the cake until it is warm, not piping hot.

Step 2: Poke the Holes

Use the handle of a wooden spoon to poke holes across the entire cake, about one inch apart. You want to make sure that the holes are big enough to allow the Jell-O to seep down into the cake, but not so big that you are ruining the cake’s structure. I usually work in a rough grid pattern and aim for about 30-40 holes across the entire cake. Don’t be timid — this is the purpose of the recipe.

Step 3: Pour the Jell-O

To start, boil 2 cups of water. Once water is boiled, take it off the heat and add your Jell-O powder, stirring until it is 100% dissolved. No granules should remain. Once your Jell-O is completely dissolved, pour it over the warm cake. Make sure it fills the holes that you poked. Some Jell-O may remain on the top, let it be. The Jell-O will absorb into the cake as it cools.

Step 4: Refrigerate

Let the cake cool to room temperature. Then, cover it and refrigerate it for at least 2 hours, or overnight if that is more convenient for you. The Jell-O needs time to set completely inside the cake. If you don’t wait long enough, the cake will be soggy and fall apart when you cut it.

Step 5: Top with Cool Whip and Serve

After the Jell-O has completely set, spread the cooled whip over the cake in a smooth, even layer. If you have fresh strawberries, you can add some on top for a fresh and pretty presentation. Cut and serve cold.

Helpful Tips

Don’t skip the milk swap

Using water instead of milk when making cake mix creates a big difference. The box instructions aren’t going to tell you to do this, but many bakers do this. Using milk instead of water creates a cake that is richer, but also moister and more flavorful. The amount used is the same./

Make the holes big enough

Poke cake is a common mistake saying that holes created in the cake are too small. Forks and skewers just leave Jell-O sitting on the top of the cake and not really soaking into the actual cake. For this, you want a thick wooden spoon, or something like that which makes a hole about a half inch wide.

Thaw your Cool Whip in the fridge, not on the counter

When thawed at room temperature, Cool Whip can become too thin and can be difficult to spread. If you put Cool Whip in the freezer the night before (or if you put it in the freezer at least 4 hours in advance), it will spread much more easily over the Jell-O that has set.

Fresh strawberries on top are optional but worth it

The Jell-O infuses the cake with strawberry flavor, but fresh sliced strawberries on top just before serving provide color and a bit of brightness that the Cool Whip doesn’t do. If you’re serving this at a party, or taking it somewhere, add the strawberries just before you leave — they look amazing and they take under two minutes to do.

Use a good baking pan

A metal 9×13 pan will bake the cake more evenly than a glass one. If you are using glass, add an additional 5 minutes to the baking time, and wait for the edges to pull away from the pan before removing the cake from the oven. For a party, you can use a disposable foil pan for easy transport and no pan to wash.

A good metal 9×13 pan is worth keeping in your cabinet. It’s what I use for this cake, brownies, bars — everything. The even heat makes a real difference.

Variations and Substitutions

Change the Jell-O flavor

While strawberry Jell-O is the traditional option, feel free to use any flavor. If you’re using white cake then cherry and raspberry are both excellent choices. For a more poke cake-like experience, go for Lemon Jell-O. In the summer, orange makes a nice choice. The method stays the same, so use whichever 3 oz box you have!

Use a yellow cake mix instead

White cake looks cleaner than yellow cake — it will be clearer when cake is cut and pink Jell-O streaks can be seen. Yellow cake mix tastes just as good though. The color inside may be a little more toned down. Both work.

Add fresh strawberries to the filling

Some people slice fresh strawberries and layer them on the cake before pouring the Jell-O so the berries become embedded in the cake as the Jell-O sets. This gives the cake some real strawberry texture on the inside and not just the top. I have also done this if I have extra berries to use up and it looks nice.

Cream cheese Cool Whip topping

To start, beat 8 oz softened cream cheese until smooth. Then, fold in some of the thawed Cool Whip. This makes a thicker topping that can slice even cleaner and holds up even better than the others. It’s the one I make when I’m taking this somewhere and want it to look good.

Make-Ahead, Storage, and Leftovers

Make-ahead: This is truly one of the best desserts to make ahead of time. Prepare this a day before you need it. Once it is made, cover it tightly with plastic wrap and store it in the fridge overnight. The Jell-O will settle overnight and the flavors will blend nicely. Wait to put on the Cool Whip until the day of serving, and the add fresh strawberries just before serving.

Storage: Store leftovers covered in fridge. Cool Whip is good for 3-4 days. After that the topping will start getting a little watery and the texture of the cake will change. It is still safe to eat; it just won’t be as good.

Freezing: You can freeze this, but the Cool Whip topping does not defrost well, as it gets watery and separates. If you want to freeze it, do so before the topping has been added. Wrap the Jell-O-soaked cake well and freeze for up to 1 month. To serve, thaw in the refrigerator overnight, then top with Cool Whip.

Transporting: This cake is easy to transport as it is in its final container. Simply cover it with plastic wrap and keep it cold during transport. At the party it is fine to be out of the fridge for a few hours — just don’t let it sit in the sun.

Frequently Asked Questions

Can I use sugar-free Jell-O?

You can do this, but the results will be a little different. Sugar-free Jell-O will not hold as firmly, leading to a wetter cake, and the texture will be less defined when cutting. If sugar is a concern, it will still taste fine, just know the consistency will be a little different.

How far in advance can I make this?

One day ahead is the sweet spot. Two days is okay. \n\nAfter that, the texture of the cake will change, and the Cool Whip can get a little watery. For the best results, bake and Jell-O the cake the night before, then add the Cool Whip topping in the morning and put fresh berries on right before serving.

Does the cake need to be fully cooled before adding Jell-O?

No, and it shouldn’t be. When the cake is warm, Jell-O soaks in better. Let it cool for about 5 minutes after it comes out of the oven, poke the holes, and then you can pour the Jell-O. As long as the cake is not completely cooled to room temp, it will not be sitting on top, as Jell-O will be soaking in.

Can I use homemade whipped cream instead of Cool Whip?

It technically is yes, but it won’t stay the same way. True whipped cream deflates after a couple hours in the fridge and can get a little weepy. If you want to use real cream, you can stabilize it with a bit of cream cheese or instant pudding mix. Or just go with Cool Whip— that’s what this recipe is intended for and it does the job!

Why is my poke cake soggy?

There are a few factors that could lead to this happening. Maybe the Jell-O was too hot when poured. This can affect the structure of the cake. Possible additional liquid was added. Or the dessert simply didn’t chill long enough. Be certain to use 2 cups of boiling water for the Jell-O and to NOT use the box instructions that require cold water bc that will have an impact. For poke cake, instructions state to dissolve in 2 cups boiling water only, and to pour that on the cake immediately. The cake needs to chill for a full 2 hours minimum.

What if I don’t have a wooden spoon handle to poke the holes?

Use anything you have that has a hole about half an inch wide. This could include a thick chopstick, a spatula, or even the handle of a butter knife. Just make sure that the holes are large enough for the Jell-O to actually get inside. Small holes created by a skewer or a fork, for example, are not very effective.

Serving Ideas

This cake is perfect for spring and summer get-togethers. Think Mother’s Day, Memorial Day, July Fourth, graduation parties. It’s cold, can be easily portioned into square servings, and feeds a lot of people right from the pan. Here are some ideas to make it feel a little more special:

• Top individual slices with a few sliced fresh strawberries right before serving
• Add a drizzle of strawberry sauce or jam thinned with a little water if you want even more strawberry flavor on top
• Serve alongside a scoop of vanilla ice cream if you’re serving it as a sit-down dessert rather than a buffet item
• Garnish with mint leaves if you have them — the color contrast looks great against the white Cool Whip
