The Pineapple Upside Down Cake by Hairy Bikers is a light, fluffy sponge cake that is baked with pineapple rings and cherries at the bottom of the tin. Once baked and flipped upside down, the cake reveals a caramelized, golden pineapple top. The combination of the buttery cake with the sweet and tangy pineapples makes this dessert a nostalgic favorite for all ages.
