This Watergate Cake is a vintage recipe your family will love. It’s made with pistachio pudding and is an excellent addition to any spring/summer gathering.

If you are a fan of pistachio, you will definitely need to make the classic Watergate Salad! It’s a wonderful addition to any holiday; some people call it the “green stuff”.
❤️WHY WE LOVE THIS RECIPE
This cake is made from a cake mix, which makes is super simple and it comes together really quickly. We love the combination of pistachio and coconut. It just goes really well together, and the cake is very moist, you add a cool whip frosting, and you have a delicious dessert. It’s so pretty too, so it’s perfect for Easter, St. Patrick’s Day or Mother’s Day!
SWAPS
If you are not a fan of pecans, you can substitute the nuts or leave them out. Yes, this cake is made with Cool Whip. No, I don’t think you can make your own. I don’t think it will work because the stability of the Cool Whip makes the frosting. You can always try it, but I recommend using Cool Whip.

⭐TIP
Cake mix sizes have changed over the years but this recipe works fine. We prefer the white cake mix, it makes the cake much prettier. You can use a yellow cake mix in a pinch. You can also make this cake in day in advance and it must be kept in the refrigerator.
