This key lime cake started out as a poke cake, but I made the syrup to thick to pour, but it was so delicious that I had to post it anyway. This way it is like there is a filling between the cake and the whipped cream. If you want to try and make it a poke cake, then leave the cornstarch out of the filling, and it should work great. If anyone does this, please let me know how it turns out. I will try it eventually, but I’m getting in the mood for fall, and don’t think I’m going to be making key lime cake again soon. I also wanted to make a key lime cake that was completely from scratch because all of the recipes I have seen for key lime cake were doctored cake mixes, and I really prefer to do it all from scratch.
