Key Lime Poke Cake

Key Lime Poke Cake is a refreshing citrus dessert made with a tender white cake soaked in tangy key lime filling, topped with whipped cream and lime zest—perfect for warm-weather gatherings and easy entertaining.

Ingredients

Scale
  • 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

Instructions

  1. Preheat oven and prepare cake mix according to package directions. Bake in a 9×13-inch pan and let cool for 10 minutes.
  2. Using the handle of a wooden spoon, poke holes all over the cake, about 1 inch apart.
  3. In a bowl, whisk together sweetened condensed milk, key lime juice, and lime zest until smooth.
  4. 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.
  5. In a chilled bowl, whip heavy cream with powdered sugar and vanilla until stiff peaks form.
  6. Spread whipped cream over the chilled cake. Garnish with lime zest or slices if desired.
  7. 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.
