Preheat and Prepare Pan:
Preheat the oven as per the lemon cake mix instructions. Grease a 9×13 inch baking dish.
Bake the Cake:
Prepare and bake the lemon cake mix as directed on the box. Pour the batter into the prepared dish and bake until a toothpick comes out clean.
Let the cake cool slightly, then poke holes over the top using a wooden spoon handle, spaced about 1 inch apart.
Add Jell-O:
Prepare the lemon Jell-O according to package directions but only let it cool slightly without setting.
Pour the liquid Jell-O over the cake, filling the holes.
Chill:
Refrigerate the cake for an hour to allow the Jell-O to set.
Prepare Pudding Layer:
Whisk lemon pudding mix with cold milk until thickened, then fold in the whipped topping.
Spread this over the Jell-O layer on the cake.
Chill Again:
Refrigerate the cake for at least 2 hours.
Serve:
