How to Make Key Lime Poke Cake
- Bake the Cake:
Preheat your oven and prepare the cake mix according to the package instructions. Bake in a 9×13-inch pan until done. Let it cool for about 5 minutes. - Poke the Cake:
Using the handle of a wooden spoon, poke holes all over the cake. Be careful not to poke through the bottom — you just want deep pockets for the filling to soak in. - Prepare the Filling:
In a medium bowl, whisk together the sweetened condensed milk, heavy cream, and lime zest. Slowly add the key lime juice and whisk until the mixture thickens slightly. - Add the Filling:
Pour the filling evenly over the warm cake, using a spatula to help it flow into the holes. Cover and refrigerate for at least 1 hour, or overnight for best results. - Make the Topping:
In a clean bowl, beat the whipping cream and vanilla extract until it begins to thicken. Gradually add powdered sugar and continue beating until stiff peaks form. - Frost and Garnish:
Spread the whipped cream topping over the chilled cake. Garnish with lime zest or thin lime slices for a decorative touch. - Serve and Enjoy:
Slice and serve chilled for the most refreshing flavor experience!
Storage
- Refrigerator: Keep the cake covered and chilled for up to 4 days.
- Freezer: Freeze individual slices tightly wrapped for up to 2 months. Thaw overnight in the fridge before serving.
- Tip: This cake tastes even better the next day as the flavors blend and deepen.
