Sourdough Discard Pineapple Upside-Down Cake

This pineapple upside down-cake is so moist, soft and tender with a delicious caramel topping that’ll make you wonder why people bother with frosting at all.

Pineapple upside-down cake is a favorite in my household so I really wanted to get this recipe right. I wanted to incorporate my sourdough discard in the recipe because well…my overflowing discard jar is basically my excuse for baking and eating sweet treats like banana bread, oatmeal cookies and chocolate chip cookies.

Speaking of unhealthy treats, this pineapple upside-down cake is not a health food. This cake has a lot of sugar, butter and even alcohol (rum, which is optional but highly recommended). I’m not kidding there’s TONS of sugar in this recipe, by weight, it’s more sugar than flour. This cake is an indulgence, and believe me, it tastes like it too.

I based this recipe on the epicurious recipe for pineapple upside-down cake, and converted it to sourdough. I’ve used other recipes before but this one resulted in the best tasting cake. It had an incredibly soft, tender, and crumbly crumb, and a wonderfully complex multi-dimensional flavor thanks to the addition of rum and cardamom. Cardamom really put this cake’s flavor over the top, so far if you don’t already have it in your spice rack, I definitely recommend purchasing some before making this recipe.

Preheat oven to 350 F / 176 C

Add eggs, 1 at a time, beat well and wait until fully incorporated before each addition.  

Beat in sourdough starter, vanilla and 2 tablespoons of rum.

Add half of flour mixture and beat on low speed just until blended. Careful not to over beat or cake may turn out rubbery.

Beat in pineapple juice, then add remaining flour mixture, beating just until blended. Your batter may look curdled, this is ok.

Spoon batter over pineapple topping and spread evenly.
