- 1 box white cake mix (plus ingredients listed on box: eggs, oil, water)
- 1 cup sweetened condensed milk
- 1/2 cup key lime juice (fresh or bottled)
- 1 tablespoon key lime zest
- 1 cup heavy whipping cream
- 1/4 cup powdered sugar
- 1 teaspoon vanilla extract
- Optional: lime slices or zest for garnish
- Preheat oven and prepare cake mix according to package directions. Bake in a 9×13-inch pan and let cool for 10 minutes.
- Using the handle of a wooden spoon, poke holes all over the cake, about 1 inch apart.
- In a bowl, whisk together sweetened condensed milk, key lime juice, and lime zest until smooth.
- Pour the lime mixture evenly over the cake, making sure it seeps into the holes. Let cool completely, then refrigerate for at least 2 hours.
- In a chilled bowl, whip heavy cream with powdered sugar and vanilla until stiff peaks form.
- Spread whipped cream over the chilled cake. Garnish with lime zest or slices if desired.
- Slice and serve cold. Store leftovers covered in the refrigerator.
Notes
- Use key limes for the most authentic flavor, but Persian limes can be substituted.
- Make sure cake is slightly warm when pouring filling to help absorption.
- Whipped topping or cream cheese frosting can be used as an alternative to whipped cream.
- This cake improves in flavor after chilling overnight.
