Ingredients
- 1 box white cake mix plus ingredients required on the box
- 4 eggs
- 1 cup milk
- 1/3 cup vegetable oil
- 3 cups lime curd (homemade or store-bought)
- 1 package (3 oz) JELL-O lime flavor gelatin
- 1 1/2 cups boiling water
- 2 cups heavy whipping cream (full fat and cold)
- 4 tablespoons sugar
- 1 teaspoon vanilla extract
- 1 tablespoon lime juice
- Zest of 1 lime
- Sliced lime, for garnish

Instructions
- Step 1: Preheat your oven to 350°F (175°C). Grease and lightly flour a 9×13 inch cake pan.

- Step 3: Allow the cake to cool for about 10 minutes. Then, use the bottom of a wooden spoon to poke holes evenly all over the cake.
- Step 4: While the cake cools, dissolve the lime JELL-O gelatin in boiling water. Stir until fully dissolved and pour this mixture evenly over the cake, letting it soak into the holes.
- Step 5: Spread the lime curd evenly on top of the cake, pressing it gently into the holes and reaching all corners.
- Step 6: Let the cake cool to room temperature before preparing the whipped cream.
- Step 7: In a large bowl, beat the heavy whipping cream with sugar, vanilla extract, lime juice, and lime zest until stiff peaks form.
- Step 8: Spoon the lime whipped cream evenly over the cake and smooth the top with a spatula.
- Step 9: Refrigerate the cake overnight or for at least 8 hours to allow flavors to meld and the cake to set.
- Step 10: Before serving, garnish with fresh lime zest and lime slices for an attractive finishing touch.
Tips & Variations

- Use homemade lime curd for a fresher, more intense flavor.

Storage
Store the cake covered in the refrigerator for up to 3 days. Keep it chilled to maintain the whipped cream’s texture. When ready to serve, slices can be eaten cold or brought to room temperature for 15-20 minutes for a softer bite.

- 1 package (3 oz) JELL-O lime flavor gelatin
- 1 1/2 cups boiling water

Garnish
- Sliced lime

Instructions
- Prepare White Cake: Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch cake pan to prevent sticking. Prepare the white cake mix according to the box instructions using the required eggs, milk, and vegetable oil. Pour the batter into the prepared pan and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Allow the cake to cool for 10 minutes.
- Poke Holes in Cake: Using the bottom of a wooden spoon, gently poke holes all over the warm cake to create space for the gelatin and lime curd to seep in, maximizing flavor infusion.
- Make Gelatin Mixture: While cake cools, dissolve the lime-flavored gelatin powder in 1 1/2 cups of boiling water. Mix thoroughly until the gelatin is fully dissolved.
- Add Gelatin to Cake: Pour the warm gelatin evenly all over the poked holes and cake surface, allowing it to soak into all parts of the cake.
- Spread Lime Curd: Evenly spread the lime curd over the top of the cake, carefully filling the holes and ensuring the corners also receive filling for consistent flavor.
- Cool to Room Temperature: Allow the cake to cool completely to room temperature before proceeding to the topping step.
- Prepare Lime Whipped Cream: In a large mixing bowl, combine heavy whipping cream, sugar, vanilla extract, lime juice, and lime zest. Beat the mixture until stiff peaks form, creating a fluffy and tangy whipped cream.
- Top the Cake: Using a spoon or spatula, spread the lime whipped cream evenly over the cooled cake, smoothing the top for a neat finish.
- Refrigerate: Refrigerate the cake overnight or for at least 8 hours to allow flavors to meld and the cake to set nicely.
- Garnish and Serve: Just before serving, garnish the cake with fresh lime zest and lime slices to enhance presentation and add a fresh citrus aroma.
Notes
- For best results, use fresh lime zest and juice to enhance the citrus flavor in the whipped cream and garnish.
- If you prefer a less sweet dessert, reduce the sugar in the whipped cream topping slightly.
- The lime gelatin helps infuse a tart flavor while moistening the cake layers perfectly.
- The cake needs to be refrigerated for at least 8 hours to fully set and develop its characteristic poke cake texture.
- You can substitute lime curd with lemon curd for a slightly different citrus flavor variation.
