Strawberry Jello Poke Cake with Fluffy Whipped Topping
This Strawberry Jello Poke Cake is a retro dessert that’s cool, fruity, and ridiculously easy to assemble. It starts with a simple white cake and turns into something soft, pink, and bursting with strawberry flavor after a quick soak.
You bake a boxed mix until it’s just set, poke holes all over, and pour a packet of strawberry gelatin right into the warm cake. As it chills, the cake drinks up the bright red liquid and stays moist for days. A thick layer of whipped topping and a handful of fresh berries on top make every slice look like a party.
Why This Strawberry Poke Cake Works
The cake stays moist long after you cut it because the Jello sets inside every pore, while the whipped topping keeps the whole thing light and creamy. It’s not overly sweet, just bright and refreshing.
It’s the kind of dessert you can make ahead, stash in the fridge, and forget about until guests arrive. The pink slices with billowy white frosting look festive on any plate, and both kids and adults reach for seconds.
Ingredients
- 1 box (15.25 oz) white cake mix: plus the eggs, oil, and water called for on the package (typically 3 large eggs, 1/2 cup vegetable oil, and 1 cup water)
- 1 package (3 oz) strawberry Jello: use the regular, not sugar-free, for the best set
- 1 cup boiling water: to dissolve the gelatin
- 1/2 cup cold water: to cool the liquid before pouring
- 1 container (8 oz) frozen whipped topping, thawed: Cool Whip or a similar brand
- Fresh strawberries: for garnish
Variations / Substitutions
- Swap the Jello flavor: raspberry, lime, and orange all work beautifully with a white cake base.
- Change the cake: yellow cake mix gives a buttery note; lemon cake plus strawberry Jello makes a cheerful summer dessert.
- Homemade whipped cream: beat 2 cups heavy cream with 2 tablespoons powdered sugar until stiff peaks form and spread it in place of the whipped topping.
- Dairy-free option: use a dairy-free whipped topping and prepare the cake mix with oil and water, no milk.

How to Make Strawberry Jello Poke Cake
Step 1: Bake the White Cake Layer
Heat your oven to 350°F (175°C) and grease a 9×13-inch baking dish. Prepare the white cake mix according to the package directions using the 3 large eggs, 1/2 cup vegetable oil, and 1 cup water. Pour the batter into the dish and bake for 25 to 30 minutes, until a toothpick inserted in the center comes out clean.
The top will be pale and spring back lightly when pressed. Let the cake cool on a wire rack for 15 minutes. It should feel warm to the touch but not steaming hot, which helps the Jello absorb properly without turning gummy.
Step 2: Soak the Cake with Strawberry Jello
Grab the handle of a wooden spoon or a fork and poke holes all over the warm cake, spacing them about an inch apart. In a small bowl, dissolve the entire 3-oz package of strawberry Jello in 1 cup boiling water, stirring until the granules are totally gone. Stir in 1/2 cup cold water, then slowly pour the liquid Jello evenly over the cake, letting it settle into every hole.
The bright liquid will pool on the surface as you pour. As the cake chills, it turns a rosy pink and firms up. Move the pan to the refrigerator and chill for at least 2 hours, until the Jello is fully set.
Step 3: Spread the Whipped Topping
Take the cake out of the fridge. Scoop the 8 oz of thawed whipped topping onto the cold cake and spread it into a smooth, even layer all the way to the edges. Work gently so you don’t pull up the stained top.
The white topping will cover the pockmarked surface completely, but you’ll see ribbons of pink Jello peeking through later when you slice. Keep the cake chilled until you’re ready to garnish.
Step 4: Garnish with Fresh Berries and Serve
Just before serving, slice a handful of fresh strawberries and scatter them over the whipped topping. Cut the cake into squares with a sharp knife and lift each piece out with a flat spatula.
The cool, creamy frosting with juicy berries makes every bite feel like summer. Serve it straight from the fridge while it’s frosty and firm.
Tips for a Flawless Poke Cake
- Make sure the cake is still warm when you poke and pour. If it’s completely cool, the Jello won’t soak in evenly and can pool on top.
- Stir the Jello until every speck of powder dissolves. Undissolved granules will leave grainy, rubbery spots in the cake.
- Use the narrow end of a wooden spoon for neat holes. The thicker the pokes, the more Jello infuses each bite.
- Thaw the whipped topping in the fridge overnight, never in the microwave. A cold, firm topping spreads cleanly without melting.
Storing Leftover Poke Cake
- Refrigerate: the cake tightly covered for up to 4 days. The whipped topping may weep a tiny bit after a day, but the cake stays wonderfully moist. Serve it straight from the fridge.
Frequently Asked Questions
Can I use homemade whipped cream instead of Cool Whip?
Yes, 2 cups heavy cream whipped with 2 tablespoons powdered sugar works well. It tastes richer but softens faster, so plan to serve the cake within a day.
Why did my Jello pool on top instead of soaking in?
The cake was probably too cool when you poured. Always poke and pour while the cake is still warm, and give the liquid a few seconds to sink into the holes before you move the pan.
Can I make this without a boxed cake mix?
Absolutely. Bake a 9×13-inch homemade white cake from your favorite recipe. Just be sure it’s fully baked and still warm when you start poking.
