Instructions

To make the cake

1. Preheat oven to 350*.
2. In a large bowl, combine cake mix and can of seltzer (no need to add eggs or oil!)
3. Bake in a large rectangular cake pan (or 2 if you would like “thinner” pieces) for about 20-30 minutes until done. Let Cool.

While the cake is in the oven:

1. Whip cream cheese in a large bowl until light and fluffy.
2. Add pudding mix until incorporated.
3. Add milk until smooth.
4. Next, add whipped topping and mix on slow speed until combined.
5. (Add green food coloring at this point, if you are coloring it.)

Assemble:

1. Break up cooled cake into pieces.
2. Using a large trifle bowl or small individual cups, create alternating layers of cake pieces, key lime pie filling, and whipped mixture
