This strawberry jello poke cake brings back memories of summer potlucks and family gatherings. The combination of moist white cake infused with strawberry jello and topped with cool whip creates a refreshing dessert that never fails to impress. I discovered this recipe years ago when looking for a simple yet stunning dessert, and it has become one of my most requested treats.
I first made this cake for my daughter's birthday when I was short on time, and it was such a hit that it has become our official summer celebration cake. The vibrant red jello peeking through each slice makes it look like you spent hours in the kitchen.
Ingredients
- White cake mix: Following the instructions on the box for a light and fluffy base
- Strawberry jello: 3 ounce box adds vibrant color and sweet berry flavor
- Cool Whip: 8 oz container creates the perfect creamy topping that complements the cake
Step-by-Step Instructions
- Bake the Cake:
- Follow the instructions on your white cake mix box precisely, measuring ingredients carefully. Allow the cake to cool completely in the pan for at least one hour until it reaches room temperature. This cooling step is essential before adding the jello.
- Create the Poke Holes:
- Once cooled, use the round handle end of a wooden spoon to poke holes throughout the entire cake surface. Space holes about 1 inch apart and ensure they go at least halfway through the cake to allow the jello to penetrate deeply.
- Prepare and Add the Jello:
- Mix the strawberry jello with hot water according to package directions but do not refrigerate it. Instead, pour the liquid jello carefully over the entire cake, ensuring it fills all the holes. Some jello will remain on top which is perfect.
- Chill the Cake:
- Refrigerate the jello infused cake for a full 4 to 5 hours or preferably overnight. This resting time allows the jello to set completely within the cake creating those beautiful jello pockets.
- Add the Finishing Touch:
- Spread Cool Whip in an even layer across the top of the chilled cake using an offset spatula for the smoothest finish. Return to the refrigerator until ready to serve.

The first time I made this cake, I was skeptical about pouring liquid jello over my perfectly good cake. But watching my family's faces light up when I served those first colorful slices convinced me this simple technique creates magic. The contrast between the soft cake, jiggly jello pockets, and creamy topping creates a texture experience unlike any traditional cake.
Storage Tips
This cake actually improves with time in the refrigerator. The jello has more opportunity to set and infuse flavor throughout the cake. Store covered in the refrigerator for up to 4 days. The cake will remain moist thanks to the jello infusion, unlike regular cakes that dry out. I recommend using a cake container with a lid rather than plastic wrap which might stick to the Cool Whip topping.
Flavor Variations
While strawberry is classic, this recipe works beautifully with any jello flavor. Try raspberry or cherry for similar red hues, or explore more adventurous combinations like lime jello with a lemon cake base. For a special occasion, match the jello color to your party theme. During holidays, I make this with lime jello for Christmas or orange for Halloween gatherings. You can also replace the Cool Whip with homemade whipped cream flavored with a splash of vanilla.
Serving Suggestions
For an extra special presentation, garnish each slice with fresh strawberry slices or whole berries just before serving. This cake pairs wonderfully with a scoop of vanilla ice cream for an even more decadent dessert. For brunches, serve smaller slices alongside coffee. I find chilling the serving plates for about 15 minutes before plating helps the cake maintain its structure and makes for a cleaner presentation.
