Key Lime Poke Cake is an easy cake recipe, combining a layer of white cake, a layer of zesty key lime filling and topped with some heavy whipped topping.
Prepare the cake according to the package instructions in a 9x13 inch baking dish and allow to cool completely.
Use a fork or wooden skewer to poke small holes all over the cake.
In a medium bowl, whisk together the condensed milk, lime juice, whipping cream, lime zest, and green food coloring until just combined.
Spread the mixture over the top of the cake. Cover the pan and place the cake in the refrigerator to chill for one hour.
Spread the whipped topping over the entire cake. You may not need the whole container to cover the cake. Cover the pan and return the cake to the refrigerator to chill for at least one hour or up to overnight.
Top the whipped cream with lime zest and lime slices before serving.
