This Watergate Sheet Cake is nutty and moist thanks to pistachio pudding and pecans. Topped with a sweet, light whipped cream topping and coconut, this cake has it ALL, and it's easy to make too!
In large mixer bowl at medium speed, add cake mix, oil, pudding, eggs, and lemon lime soda. Fold in chopped pecans and coconut. Pour into greased & floured 13x9 baking dish and bake in a 350 degree oven for 32-35 minutes. Cool completely.
To frost, while cake is baking, beat pudding with milk until light & fluffy, about two minutes. Fold in Cool Whip. Refrigerate for 30 minutes or more then spread over cooled cake.
Sprinkle with pecans and coconut. Refrigerate and enjoy.
Notes
Pudding Mix. Be sure to use INSTANT pudding mix for this recipe. And try NOT to choose the "sugar free" option.
Some of you will ask if you can substitute anything for the 7 UP in the recipe. You can use other lemon lime soda, or even Fresca. You can also choose carbonated water (like La Croix). The carbonation helps create air bubbles in the batter, creating a light and fluffy texture! This is why I LOVE my 7UP Pound Cake recipe!
If you choose to not use Cool Whip, you can substitute Dream Whip (2 envelopes mixed with the milk. Then add pistachio pudding mix and beat). Or you can make a homemade whipped cream and add pistachio pudding. Our stabilized whipped cream is a copycat cool whip recipe and perfect for today.
