What You Need for Summer Berry Poke Cake Recipe
- For the Cake: 1 box (15.25 oz) vanilla or white cake mix, plus the ingredients listed on the box (typically eggs, oil, and water).
- For the Soak: 1 (3 oz) box of strawberry or mixed berry Jell-O gelatin. I get mine from Amazon because I always forget it at the store.
- For the Topping: 1 cup boiling water, 1 cup cold water, 1 (8 oz) tub of whipped topping (like Cool Whip), thawed, or 2 cups of freshly whipped cream.
- For the Garnish: 2 cups mixed fresh berries (strawberries, blueberries, raspberries).
How to Make Summer Berry Poke Cake Recipe
First, bake your cake according to the package directions in a 9×13 inch pan. Let it cool for about 20 minutes. While it cools, dissolve the Jell-O powder in the boiling water, then stir in the cold water. This is your magic potion.
Step 1: Poke the Holes
Use the handle of a wooden spoon or a large straw to poke holes all over the warm cake. Go all the way to the bottom. Don’t be shy, you want lots of channels for the Jell-O.
Step 2: Pour the Soak
Slowly and evenly pour the liquid Jell-O mixture over the entire cake, aiming for the holes. It will look like a lot, but the cake will absorb it. Tilt the pan to help it spread.
Step 3: Chill Thoroughly
Refrigerate the cake for at least 2 hours, or until completely chilled and set. This step is non-negotiable for the perfect texture.
Step 4: Frost and Garnish
Spread the thawed whipped topping evenly over the chilled cake. Pile the fresh berries on top. Slice and serve cold. It’s a different vibe than my fluffy Japanese souffle pancakes, but just as satisfying in its own cool, creamy way.

Tips for Perfect Summer Berry Poke Cake
Poke While Warm
The cake should still be warm when you poke it. A warm cake absorbs the liquid much better than a cold one, ensuring every bite is infused with berry flavor.
Chill Completely
Let the cake chill for the full time, or even overnight. This allows the Jell-O to fully set within the cake, giving it that signature moist, yet sliceable texture. It firms everything up beautifully.
Get Creative with Toppings
While fresh berries are classic, you can mix it up. Try a drizzle of lemon curd, a sprinkle of toasted coconut, or even some white chocolate shavings. It’s a great canvas, much like my blueberry lemon ricotta pancakes are for breakfast.

Frequently Asked Questions
Can I use a homemade cake instead of a mix?
Absolutely. Use your favorite vanilla or white cake recipe baked in a 9×13 pan. The method is exactly the same.
Can I make this cake ahead of time?
Yes, it’s actually better the next day. Assemble the cake with the Jell-O soak up to 24 hours in advance, then add the whipped topping and berries just before serving.
Why is my cake soggy?
This likely means the Jell-O mixture wasn’t fully absorbed before chilling. Make sure your holes go to the bottom and pour slowly, letting it seep in before adding more.
I hope this becomes your new go-to summer treat. Let me know in the comments what berry combo you try.
Summer Berry Poke Cake
Ingredients
Method
- Preheat oven to 350°F (175°C). Grease and flour a 9x13-inch baking pan. Prepare the white cake mix according to package directions. Pour batter into the prepared pan and bake for 28-32 minutes, or until a toothpick inserted into the center comes out clean. Remove from oven and let cool in pan on a wire rack for 10 minutes.
- While the cake is cooling, in a medium bowl, whisk together the boiling water and raspberry gelatin until completely dissolved. Using the handle end of a wooden spoon or a large straw, poke holes all over the warm cake, going about 3/4 of the way down. Slowly and evenly pour the liquid gelatin mixture over the entire cake, aiming for the holes. Refrigerate the cake, uncovered, for at least 1 hour to set.
- In a medium bowl, combine the sliced strawberries, raspberries, and blueberries with the 2 tablespoons of granulated sugar. Gently toss and let sit at room temperature for 20-30 minutes. This draws out their natural juices, creating a flavorful syrup.
- In a large, chilled bowl, combine the cold heavy whipping cream, 1/2 cup powdered sugar, and vanilla extract. Using a hand mixer or stand mixer fitted with a whisk attachment, beat on medium-high speed until stiff peaks form. Be careful not to over-whip into butter.
- Remove the chilled cake from the refrigerator. Spread about two-thirds of the whipped cream evenly over the top of the cake. Spoon the macerated berries and their collected juices evenly over the whipped cream layer. Dollop or spread the remaining whipped cream over the berries. Garnish the top with the reserved 1/2 cup of fresh mixed berries.
- Cover the cake loosely and refrigerate for at least 2 hours, or until ready to serve. This allows the flavors to meld and the cake to firm up for easier slicing. Dust with powdered sugar just before serving, if desired.
