This Pistachio Pineapple Cake is a retro favorite—moist, tender, and bursting with tropical sweetness and nutty pistachio goodness. A staple in 1970s church cookbooks and community potlucks, it uses instant pistachio pudding mix for flavor and moisture, paired with crushed pineapple for natural sweetness and a soft crumb.
Finished with a fluffy whipped cream frosting and a sprinkle of chopped pistachios, this cake isn’t just dessert—it’s a slice of nostalgia that always earns rave reviews.
