Instructions

Brown Sugar Topping

Pour melted butter into a 9-inch round cake pan or an 8x8 square pan.
Sprinkle brown sugar over the butter evenly.
Place the whole pineapple ring in the center and arrange the half rings around it.
Place a cherry half in the center of each pineapple ring.
Set aside while you prepare the batter.

Cake

Preheat oven to 350°F (175°C).
In a large bowl, cream together softened butter and sugar with an electric mixer until light and fluffy.
Add eggs and mix until smooth.
Mix in the sourdough discard, then add pineapple juice and vanilla.
Add flour, salt, and baking powder. Mix until just combined — do not overmix.
Pour the batter evenly over the pineapple topping in the pan.

Bake & Flip

Bake for 25–40 minutes (start checking at 25 min), or until a toothpick inserted into the center comes out clean.
Cool for 15 minutes in the pan.
Run a knife around the edges to loosen, then place a serving plate or cake stand over the pan and flip the cake.
Carefully lift off the pan to reveal your beautiful pineapple upside down cake!
