  1. Prepare the cake mix as directed on the box, and bake in a 9x13” baking dish. 

  2. Let the cake cool for 5 minutes and then, using the end of a spatula or butter knife, poke holes in the cake, about ½” apart.

Chef’s tip

*Note: for the hot water, I place it in a glass measuring cup and microwave for 90 seconds. Heat in 30-second increments until you see the water start to boil. Then combine with the Jell-O package immediately.
