Key Ingredients & Substitutions
Yellow Cake Mix: This is the base of the poke cake. You can use any brand you like. If you’re feeling adventurous, try making a homemade yellow cake from scratch for a personal touch!
Raspberry Gelatin: The gelatin gives that lovely raspberry flavor. If you want to skip the gelatin or avoid artificial flavors, try using pureed fresh raspberries mixed with some sugar and cornstarch. This may change the texture a little, but it will be delicious!
Frozen Raspberries: Thawed raspberries work best for mixing into the cake. If unavailable, fresh raspberries are fine, but you might need to crush them a bit. Frozen berries are often easier to work with and add a nice texture.
Heavy Whipping Cream: This provides a fluffy topping. If you’re looking for a lighter option, use whipped coconut cream or a store-bought whipped topping. However, homemade whipped cream really does add a special touch!
How Do You Ensure the Gelatin Soaks in Perfectly?
Poking holes in the cooled cake is crucial for allowing the gelatin to seep in nicely. Use the handle of a wooden spoon or a skewer to make holes all over the cake. Make them pretty close together to soak up as much flavor as possible!
- Let the cake cool completely to avoid cooking the gelatin when poured.
- Pour the gelatin mixture slowly, so it has time to absorb.
- Spread the raspberry and juice mixture evenly for added sweetness and flavor.

For the Cake:
- 1 box yellow cake mix (plus ingredients called for on the box, usually eggs, oil, and water)
For the Raspberry Layer:
- 1 (3 oz) package raspberry flavored gelatin (Jell-O)
- 1 cup boiling water
- 1 (10 oz) package frozen raspberries, thawed, juice reserved
- 1 cup granulated sugar
For the Topping:

How Much Time Will You Need?
This delightful Raspberry Poke Cake will take about 20 minutes of prep time, plus around 30-35 minutes for baking. After that, you’ll need to chill it in the refrigerator for at least 2 hours before serving. So, plan for about 2 hours and 55 minutes total to enjoy this refreshing treat.
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven as directed on the yellow cake mix box. This ensures that the cake bakes evenly and rises nicely.
2. Prepare the Cake Batter:
In a mixing bowl, prepare the yellow cake mix batter according to the directions on the box. Usually, this will involve mixing the cake mix with eggs, oil, and water until smooth.
3. Bake the Cake:
Pour the batter into a greased 9×13-inch baking pan. Bake in the preheated oven until a toothpick inserted into the center comes out clean. This should take around 25-30 minutes. Once baked, allow the cake to cool completely in the pan on a wire rack.
4. Dissolve the Gelatin:
While your cake cools, dissolve the raspberry gelatin powder in 1 cup of boiling water. Stir well until the gelatin is fully dissolved and set it aside.
5. Mix the Raspberry Layer:
In another bowl, combine the thawed raspberries (make sure to reserve the juice), along with the reserved raspberry juice and granulated sugar. Mix everything together until well combined.
6. Poke the Cake:
Once the cake is completely cool, use the handle of a wooden spoon or a skewer to poke holes all over the top of the cake. This step is important as it allows the gelatin mixture to soak in!
7. Add the Gelatin:
Pour the dissolved gelatin mixture slowly over the cake, ensuring it seeps into all the holes. Take your time with this step to let the flavor fully absorb.
8. Spread the Raspberry Mixture:
Now, pour the raspberry and juice mixture over the top of the cake, spreading it evenly for a delicious topping.
9. Chill the Cake:
Cover the cake and refrigerate it for at least 2 hours or until the gelatin is set. This chilling time helps everything meld together beautifully.
10. Whip the Cream:
In a mixing bowl, whip the chilled heavy cream with the powdered sugar until medium peaks form. This will create a light and fluffy topping for your cake.
11. Add the Whipped Cream:
Once your gelatin is set, spread the whipped cream over the top of the cake, covering it completely.
12. Garnish:
Top your cake with dollops of whipped cream and fresh raspberries for a pretty decoration.
13. Serve and Enjoy:
Your Raspberry Poke Cake is now ready to serve! Slice into squares, serve chilled, and enjoy this deliciously refreshing dessert with family and friends!
Can I Use a Different Flavor of Gelatin?
Absolutely! Feel free to swap the raspberry gelatin for any flavor you prefer, such as strawberry, cherry, or even lemon for a refreshing twist. Just keep in mind that the overall flavor of the cake will change based on your choice!
How Can I Make This Cake Gluten-Free?
You can use a gluten-free yellow cake mix instead of regular cake mix. Just follow the same instructions on the packaging, and you’ll have a delicious gluten-free version of this poke cake!
What’s the Best Way to Thaw Frozen Raspberries?
The easiest way to thaw frozen raspberries is by transferring them to the fridge and letting them thaw overnight. If you’re in a hurry, you can place them in a colander and run cold water over them for a few minutes until thawed. Just be sure to reserve the juice!
How Long Can Leftovers Be Stored?
Leftover Raspberry Poke Cake can be stored in an airtight container in the refrigerator for up to 3 days. Make sure to cover it well to maintain its freshness. Just re-add some whipped cream and fresh raspberries before serving for the best taste!
