This is the very good lemon cake that Mom makes with the lime jello in it on the first day of Spring.
Topping (see note below):
Prepare 9 x 13” lemon cake normally, following box instructions. Let cake cool completely in pan.
Fully dissolve lime jello mix in the boiling water, stirring 2 min. Add cold water and stir. Refrigerate until jello begins to thicken (just under 1 hour). Whisk thoroughly.
Poke holes in cake 1” apart and pour jello in holes. Make sure each hole gets filled with jello by banging pan gently on counter, and redistributing jello on top of cake to fill holes.
To make topping: Combine Dream Whip, lemon instant pudding mix, and milk. Beat for 3-8 minutes and refrigerate. Spread on cake before eating.
Note: Alternatively, if Dream Whip is unavailable (like if you move to Houston),to make the topping without Dream Whip, use 1 cup cold milk, 1 cup Cool Whip, and lemon instant pudding mix.
