Cast iron isn’t used exclusively for savory dishes. It’s the perfect cookware for creating stunning, rustic desserts as well. There’s no better way to caramelize fruit, like for this Plum Upside-Down Cake, flavored with brown butter and orange.

Equipment
- 12" Cast-Iron Skillet
- KitchenAid 7-Speed Digital Hand Mixer
- High-Heat Scraper
- 8" Chef's Knife
- 18 x 24-Inch Plastic Cutting Board
- Glass Nesting Bowls
- Glass Liquid Measuring Cups
- Measuring Cups/Spoons Set

Ingredients
MELT
- 2 Sticks unsalted butter (16 Tbsp.)
COMBINE
- 1 ¾ cups Packed light brown sugar, divided
- 4 tbsp. Unsalted butter
- 1 tsp. Ground cinnamon, divided
- 1 ½ lb. Red plums, cut into ½-inch wedges
WHISK
- 2 cups All-purpose flour
- 1 ½ tsp. Baking powder
- 1 tsp. Kosher salt
- ½ tsp. Baking soda
BEAT
- 1 tbsp. Vanilla bean paste
- 4 Eggs
- 1 tbsp. Minced orange zest
- ¼ cup Fresh orange juice
Instructions
- Melt 2 sticks butter in a saucepan over medium heat and cook, swirling pan, until brown specks appear, 5–8 minutes. Transfer brown butter to a bowl and cool until nearly solidified.
- Preheat oven to 350°.
- Combine ¾ cup brown sugar, 4 Tbsp. butter, and ½ tsp. cinnamon in a 12-inch cast-iron skillet over medium heat, stirring until melted. Off heat, arrange plums in concentric circles over sugar mixture.
- Whisk together flour, baking powder, salt, baking soda, and remaining ½ tsp. cinnamon in a bowl.
- Beat browned butter, remaining 1 cup brown sugar, and vanilla bean paste with a mixer on medium speed until fluffy, 3–4 minutes, stopping to scrape down sides of bowl. Add eggs, one at a time, beating well after each addition. Beat in zest and orange juice. With mixer on low speed gradually add flour mixture to butter mixture, beating just to combine.
- Spoon batter over plums, spreading gently to cover skillet. Bake cake until a toothpick inserted into the center comes out clean, 30–40 minutes. Let cake sit 15 minutes, then invert onto a platter to cool completely before serving.
