Easy Strawberry Shortcake Poke Cake
Strawberry shortcake gets a poke cake makeover that’s simpler than any layer cake and just as satisfying.
A box of vanilla cake mix, a packet of strawberry gelatin, and a carton of whipped topping turn into a cool, creamy sheet cake loaded with berry flavor. No rolling, slicing, or fussy assembly required.
Why This Strawberry Shortcake Poke Cake Is a Keeper
The cake soaks up a sweet strawberry liquid and becomes ridiculously moist, almost custardy in the center, while the edges stay light and tender. Every bite lands somewhere between fluffy shortcake and a creamy strawberry dessert bar.
I keep coming back to it because it tastes like you spent way more time than you did. A few pantry staples and a quick chill do all the work, so it’s the kind of dessert you can pull off on a Tuesday night and still feel proud to serve.
Ingredients
- 1 box (15.25 oz) white or vanilla cake mix: plus the eggs, oil, and water called for on the box
- 1 cup boiling water: to dissolve the gelatin
- 1 package (3 oz) strawberry gelatin: any brand, avoid sugar-free for the best texture
- 1/2 cup cold water: cools the mixture so it pours smoothly
- 1 tub (8 oz) frozen whipped topping, thawed: like Cool Whip, or use homemade sweetened whipped cream
- 1 pound fresh strawberries: hulled and sliced
- Powdered sugar: for dusting, optional
Variations / Substitutions
- Swap the berry: use raspberry gelatin instead of strawberry and top with fresh raspberries.
- From-scratch cake: bake your favorite vanilla cake recipe in a 9×13 pan and proceed the same way.
- Dairy-free: choose a dairy-free whipped topping and check the cake mix label.
- Richer soak: stir 1/2 cup sweetened condensed milk into the cooled gelatin mixture before pouring for a creamier layer.

How To Make Strawberry Shortcake Poke Cake
Step 1: Bake the Cake
Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan. Prepare the cake mix according to the package instructions, scrape the batter into the pan, and bake until a toothpick inserted in the center comes out clean, about 25 to 30 minutes. Let the cake cool in the pan on a wire rack for 15 minutes.
The cake should be warm but not hot when you start poking, because a piping-hot crumb can cook the gelatin. If the top rose unevenly, press it gently with a clean kitchen towel to level the surface so the liquid soaks in evenly.
Step 2: Poke the Holes
Grab the handle of a wooden spoon or a large fork and poke holes all over the cake, spacing them about 1 inch apart and reaching almost to the bottom of the pan. You want enough openings so the strawberry liquid travels through every slice.
The holes should look like they’re about the width of a pencil. Deep, generous pokes create those ribbons of color and keep the center from staying dry, so don’t be shy.
Step 3: Pour the Strawberry Layer
In a medium bowl, stir together the 1 cup boiling water and the strawberry gelatin powder until it dissolves completely, about 1 minute. Stir in the 1/2 cup cold water. Slowly pour the liquid over the cake, filling the holes in stages so it seeps down instead of pooling on top.
You’ll see the cake start to absorb it right away, leaving a glossy pink surface. Once all the liquid is in the pan, move it to the refrigerator and chill for at least 2 hours, until the cake is fully set and cold.
Step 4: Top with Whipped Cream and Strawberries
When the cake is chilled, spread the thawed whipped topping over the entire surface with a spatula, taking it all the way to the edges. Arrange the sliced strawberries on top in a single layer or pile them up as high as you like.
The topping stays fluffy and holds its shape if the cake is cold. For the freshest look, slice the strawberries just before you add them, and dust the whole thing with powdered sugar right at the end for that classic shortcake finish.
Step 5: Slice and Serve
Cut the poke cake into 12 squares and use a flat spatula to lift each piece, showing off the pink soaked crumb. Serve right away while the whipped cream is cool and the berries look glossy.
Every slice has a stripe of strawberry gelatin running through the middle, which makes it look a lot fancier than the effort it took. Store any leftovers covered in the fridge.
A Few Notes Before You Start
- Wipe your knife clean between cuts so the whipped cream doesn’t drag and smear.
- If you use a clear glass pan, you can watch the gelatin soak in from the side, which makes it easier to know when it’s ready.
- For a bigger strawberry punch, use a wild strawberry gelatin or add 1 tablespoon strawberry extract to the boiling water.
- Fold 1/2 cup of the sliced strawberries into the whipped topping before spreading for a fluffy, berry-studded top layer.
Bake times for a 9×13-inch pan:
| Pan Material | Oven Temp | Bake Time |
|---|---|---|
| Metal | 350°F (175°C) | 25-30 mins |
| Glass | 350°F (175°C) | 30-35 mins |
| Ceramic | 350°F (175°C) | 32-37 mins |
Storing Leftovers
- Refrigerate: cover the pan tightly with plastic wrap or transfer squares to an airtight container. It stays fresh up to 3 days.
- Serve cold: this cake is meant to be eaten chilled, right out of the fridge, so no reheating needed.
Frequently Asked Questions
Can I use homemade whipped cream instead of whipped topping?
Yes, it works beautifully, but homemade cream softens faster, so plan to serve within a few hours of topping.
Can I make this with a sugar-free gelatin?
You can, but the cake won’t be quite as moist and the color may come out lighter. Texture and flavor improve with the regular version.
Can I use frozen strawberries?
Frozen strawberries work if you puree them for the gelatin layer, but fresh berries hold their shape better for the topping.
How far in advance can I make it?
Assemble the cake without the whipped topping and strawberries up to 1 day ahead and keep it chilled. Add the toppings just before serving so everything stays fresh and pretty.
