This Pistachio Pineapple Angel Cake is a nostalgic, no-fuss dessert that blends the airy lightness of angel food cake with the creamy sweetness of pistachio pudding and juicy pineapple. Often called a “Watergate Cake” (a retro favorite from the 1970s), it’s moist, fluffy, and bursting with tropical flavor—perfect for potlucks, summer gatherings, or a simple weeknight treat.
Best of all? It uses just 4–5 pantry staples and bakes in under 30 minutes.
