Ingredients You’ll Need
The ingredient list is short, familiar, and easy to find. Use a white cake mix when you want the pink strawberry color to show clearly, or choose yellow cake for a slightly richer, more buttery-tasting base.
Cake mix: One 15.25-ounce box of white or yellow cake mix forms the base. Follow the package directions using the listed eggs, oil, and water.
Eggs, oil, and water: The typical amounts are 3 large eggs, 1/2 cup vegetable oil, and 1 cup water. Check your box because package directions can vary.
Strawberry gelatin: A 3-ounce box supplies the strong berry flavor and beautiful color that makes this a poke cake.
Water: Use 1 cup boiling water to dissolve the gelatin completely, followed by 1/2 cup cold water.
Whipped topping: One thawed 8-ounce tub creates a soft, creamy layer across the cake.
Fresh strawberries: One pint of sliced berries provides a bright garnish and fresh flavor.
Grease the 9 x 13-inch baking dish before adding the batter. This makes serving easier and helps the cake squares release cleanly from the pan.
How to Make It Step-by-Step
Step 1: Heat the oven to 350°F and grease a 9 x 13-inch baking pan. Prepare the white or yellow cake mix with 3 large eggs, 1/2 cup vegetable oil, and 1 cup water, following the instructions printed on the box.
Step 2: Pour the batter into the greased pan and smooth it into an even layer. Bake for 30–35 minutes, checking the center with a toothpick near the end of the baking time; the cake is ready when the toothpick comes out clean.
Step 3: Place the baked cake on a cooling surface and let it rest for about 15–20 minutes. It should be warm but not piping hot, since gelatin poured over a very hot cake can make the crumb overly soft and mushy.
Step 4: Use the handle of a wooden spoon or a large straw to make holes across the cake. Space them about 1 inch apart and take them most of the way through the cake so the strawberry mixture can spread through the crumb instead of collecting in only a few spots.
Step 5: Add the strawberry gelatin powder to a bowl with 1 cup boiling water. Whisk until no dry granules remain, then stir in 1/2 cup cold water to cool and dilute the mixture.
Step 6: Slowly pour the gelatin mixture over the cake, moving evenly from one side to the other. Pause briefly as needed to let the liquid seep into the holes, taking care not to flood just one area.
Step 7: Cover the pan and refrigerate the cake for at least 1 hour, although 2 hours is preferable. This chilling time allows the gelatin to set and gives the cake a cool, sliceable texture.
Step 8: Spread the thawed whipped topping over the thoroughly chilled cake. Finish with the sliced strawberries, then keep the cake refrigerated until you are ready to serve it.
Pro Tips for the Best Poke Cake
The small details make a difference in the texture and appearance of this simple dessert. Use these kitchen tips to get consistent strawberry flavor in every serving.
Cool before poking: Let the cake rest for 15–20 minutes after baking. A slightly cooled cake absorbs the gelatin well while keeping enough structure to hold the topping.
Make plenty of holes: Holes spaced about 1 inch apart distribute the gelatin more evenly than a few widely spaced holes. Keep them deep, but avoid pushing all the way through the bottom of the pan.
Dissolve the gelatin fully: Whisk the powder into boiling water until the liquid is clear and smooth. Undissolved granules can create uneven flavor and texture.
Pour slowly: A gradual pour gives the gelatin time to enter the holes. If it pools on top, gently tilt the pan or pause for a moment before continuing.
Chill before topping: The whipped topping should go on only after the cake is cold. Otherwise, it may soften and slide instead of forming a neat layer.
Slice with a clean knife: Wipe the knife between cuts for tidy squares with visible pink streaks and a clean white topping.

Flavor Variations and Serving Ideas
Strawberry is the classic combination, but the same method works with several other fruit flavors. Replace the strawberry gelatin and fresh strawberries with raspberry gelatin and raspberries, cherry gelatin and cherries, orange gelatin and orange pieces, lemon gelatin and berries, or lime gelatin with a suitable citrus garnish.
White cake is the most popular choice because its pale crumb shows the fruit color clearly. Yellow cake gives the dessert a deeper cake flavor and a slightly richer finish, so choose it when you prefer a more buttery-tasting base.
For a pretty presentation, serve the cake in chilled squares with one or two strawberry slices on top. It is especially inviting on a brunch table, at a summer picnic, or beside a scoop of vanilla ice cream for an extra indulgent dessert.

Storage and Serving Advice
Keep the finished Jello cake refrigerated until serving because both the gelatin and whipped topping are best when cold. Cover the baking dish with plastic wrap or foil, taking care not to press the cover into the topping.
The cake is easiest to cut after it has chilled for the full recommended time. If the topping looks soft, return the pan to the refrigerator before slicing rather than trying to cut it while warm.
Prepare the cake up to 2 hours ahead for the best texture and appearance.
Add the whipped topping and strawberries after the gelatin has had time to set.
Store leftovers covered in the refrigerator and serve them cold.
Use a sharp knife and wipe it clean between portions for attractive slices.
Because the recipe makes 12–15 servings in one pan, it is well suited to sharing. Keep any uneaten portions chilled so the topping stays fluffy and the fruit remains fresh.
Easy Jello Cake Recipe
A fluffy strawberry poke cake made with boxed cake mix, strawberry gelatin, whipped topping, and fresh strawberries. It is an easy chilled dessert that serves 12–15 people.
Heat the oven to 350°F and grease a 9 x 13-inch baking dish. Prepare the cake mix with the eggs, vegetable oil, and water according to the directions on the package, then pour the batter into the prepared pan.
Bake the cake for 30–35 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool for about 15–20 minutes before adding the gelatin.
Use the handle of a wooden spoon or a large straw to poke holes about 1 inch apart across the cake. Make the holes reach most of the way through the cake without breaking through the bottom.
Whisk the strawberry gelatin powder with 1 cup boiling water until completely dissolved. Stir in 1/2 cup cold water, then slowly pour the mixture evenly over the cake so it flows into the holes.
Refrigerate the cake for at least 1 hour, preferably 2 hours, so the gelatin can set and the cake can become thoroughly chilled. Spread the thawed whipped topping over the chilled cake and garnish with sliced strawberries.
Notes
Do not pour gelatin over a piping-hot cake because the cake may become overly mushy. Chill thoroughly before topping and slicing, and keep the finished cake refrigerated until serving.
Final Thoughts
This easy Jello cake recipe proves that a memorable fruit dessert does not need a long ingredient list or advanced baking techniques. A boxed cake, strawberry gelatin, whipped topping, and fresh berries create a soft, colorful poke cake with plenty of crowd-pleasing flavor.
Give the cake time to cool before adding the gelatin, make evenly spaced holes, and refrigerate it thoroughly before topping. Those simple steps ensure that the strawberry flavor reaches throughout the cake while the whipped topping stays light and easy to spread.
Serve the chilled squares at your next gathering and watch them disappear. Once you try the strawberry version, experiment with raspberry, cherry, orange, lemon, or lime gelatin and matching fruit for a new variation whenever the occasion calls for something bright and refreshing.
