How To Make Key Lime Poke Cake
- Prepare the Cake:
- Bake the cake according to the package directions.
- Once baked, use the handle of a spoon to poke holes all over the cake. (The more holes, the better the cake will absorb the filling.)
- Add Cream:
- Evenly pour ½ cup of half-and-half or cream over the holes in the cake.
- Make the Filling:
- In a large bowl, mix the sweetened condensed milk with ¾ cup of half-and-half or cream.
- Quickly add the lime juice to the mixture and stir. (The filling will set very fast once the lime juice is added, so work quickly.)
- Fill the Cake:
- Pour the lime filling over the cake and use a spatula to work it into the holes. There will be some filling left on top, which is fine.
- Chill:
- Refrigerate the cake for at least 1 hour to let the flavors meld and the filling set.
- Frost the Cake:
- Gently spread whipped frosting or whipped cream over the top of the chilled cake.
- Garnish and Serve:
- Garnish with lime zest and lime slices, if desired.
- Store the cake in the refrigerator until ready to serve.
