Watergate Dream Cake

Sharing is caring!

This recipe for Watergate Cake has been enjoyed by my family for years. It’s creamy and luscious thanks to a box of pistachio pudding mix and Dream Whip.

Watergate Dream Cake

This year my family celebrated Christmas twice – well, sort of.  Because of busy schedules, the family celebration on one side was postponed until this month.  I think I actually liked it better this way.  December seemed a little less hectic, plus it allowed us to have a good time together in January sans all of the holiday stress.

My in-laws provided the main dish (thank you!), so I brought one of my family’s favorite easy dessert – Watergate Dream Cake.  A few simple additions to a box of cake mix, plus a creamy topping make this a winning cake.  If you like Watergate Salad, then you’re going to love this cake!

IngredientsThe day before getting together, I baked my cake in a 9 x 13 glass dish.  I allowed it to cool completely and then made the whipped topping.  The incredibly yummy topping that I make with Dream Whip.

I spread the topping on top of the cake and placed it in the refrigerator.

Then when it was time to go, I placed the cake in an insulated carrier and attached the carry tote. We drove to my in-laws, over an hour away.

Everyone is out of the dream whip. Is there a substitute for dream whip?

I am not sure. I googled it and this is some info that I found:

"Dream whip is a mix to make your own whipped cream - yes you can use it in place of Cool Whip. ... whip cream is natural, dream whip is synthetic, and cool whip is pre-whipped synthetic. If it calls for dream whip, read the recipe to see if it mixes anything other that milk and vanilla into the powder." From

I imagine that you could probably blend the pudding mix with Cool Whip or make whipped cream by beating heavy cream and then add the pudding mixture to the cream.

Lynda, Thank you for sharing a nice and easy recipe. I opted for lemon pudding, rather than pistachio, in the cake as well as the frosting for a nice summertime dessert. Yummy!

I've made this for years,. It's even better if you add drained crushed pineapple, You can even use the juice in the cake. And since I am diabetic it works just as well with the no sugar pudding.
