What Makes This Poke Cake So Moist
The secret is in the filling.
After baking, you poke holes all over the warm cake and pour a mixture of sweetened condensed milk, cream, and fresh lime juice over the top. It soaks down into every bite, making the cake incredibly soft and flavorful.
This is what gives poke cakes their signature texture and why they’re so popular.
Key Lime Poke Cake with Condensed Milk
The combination of sweetened condensed milk and key lime juice creates a rich, slightly thickened filling that is both creamy and tangy.
- The condensed milk adds sweetness and body
- The lime juice brings that bright, fresh flavor
- The mixture thickens slightly as it sits, helping it stay inside the cake
It’s simple, but it makes a big difference in both flavor and texture.
Ingredients for Key Lime Poke Cake
This easy key lime dessert uses simple pantry staples to create a rich and refreshing cake.
- White cake mix
This keeps things quick and easy. You can also use yellow cake mix if that is what you have on hand. - Water
Used to prepare the cake batter according to the mix directions. - Vegetable oil
Adds moisture and helps create a soft texture. - Eggs
Provide structure and richness to the cake. - Sweetened condensed milk
This is the key ingredient that creates that signature poke cake texture. It adds sweetness and helps the filling soak into the cake. - Heavy whipping cream
Adds richness to the filling and makes it extra creamy. You can use half and half if needed, but I prefer the texture with heavy cream. - Key lime juice
Gives the cake its bright, tangy flavor. Regular lime juice works if that is what you have. - Lime zest
Adds fresh citrus flavor and enhances the overall taste.
For the topping:
- Heavy whipping cream
Creates a light, fluffy topping that balances the rich filling. - Vanilla extract
Adds a subtle sweetness and rounds out the flavor. - Powdered sugar
Sweetens and stabilizes the whipped cream.

Frequently Asked Questions
Yes. Regular lime juice works just fine and still gives you that bright citrus flavor.
No. You can use a store-bought whipped topping if you prefer. Homemade just gives it a lighter, fresher taste.
That is normal. The lime juice reacts with the condensed milk and causes it to thicken. Just pour it over the cake quickly after mixing.
You can freeze it, but the texture is best when fresh. If freezing, do so without the whipped topping and add it after thawing.
Absolutely! This cake is even better after chilling for several hours or overnight.

Ingredients
- 15 oz box white cake mix
- 1 cup water
- ½ cup vegetable oil
- 3 eggs
- 14 oz can sweetened condensed milk
- ¾ cup heavy whipping cream
- ½ cup key lime juice
- zest of 1 lime
For the Topping
- 1 ½ cups heavy whipping cream
- 1 tsp vanilla extract
- ½ cup powdered sugar
Directions
- Preheat oven to 350 degrees F. Grease a 9×13-inch baking dish. Set aside.
- In a large bowl, beat together the cake mix, water, vegetable oil, and eggs for 2 minutes. Pour into the greased pan. Bake for 22-28 minutes until a toothpick inserted into the center comes out clean.
- While the cake is still warm, use the handle of a wooden spoon or a wooden skewer to poke holes all over the top of the cake.
- In a medium bowl, add sweetened condensed milk, whipping cream, and lime zest. Whisk to combine. Add lime juice and whisk quickly. Before the mixture thickens, pour it over the cake and use a spoon to spread it to cover the cake completely. Refrigerate the cake for at least 1 hour or overnight.
- When ready to serve, beat heavy whipping cream and vanilla extract in a small bowl until it starts to thicken. Add the powdered sugar and continue beating until stiff peaks form. Spread over the cold cake. Garnish with sliced limes or lime zest.
