This is from Rose Levy Berenbaum's 'The Cake Bible' - yummy!
Preheat oven to 350F; use a 10 inch cast iron skillet, or a 10 inch round cake pan.
FRUIT TOPPING:
14 pineapple slices, fresh or canned (packed in unsweetened juice)
14 pitted sweet cherries (or -horrors! - maraschinos!)
4T unsalted butter
1/2 cup firmly packed light brown sugar
1/4 cup pecan halves
Drain pineapple slices and cherries and place on paper towels to absorb extra moisture. You'll need 8 whole slices and 8 whole cherries, and halve the remaining six of each. In the skillet, melt butter over medium heat, stir in the brown sugar until moistened and remove from heat.
Place 1 whole pineapple slice in the center of the pan and 7 whole slices surrounding it; place the half slices side by side against the sides of the pan, the two cut edges down, touching the brown sugar. Place the whole cherries in the center of the whole pineapple slices, and the halved cherries int eh center of the half slices. Tuck the pecans into any gaps between the fruit.
CAKE:
3 large egg yolks
1/2 cup sour cream
1 tsp. vanilla
1 1/2 cups sifted cake flour
3/4 cup sugar
3/4 tsp. baking powder
1/4 tsp. baking soda
1/4 tsp. salt
9 T soft unsalted butter
In a medium bowl, lightly combine yolks, about 1/4 of the sour cream, and the vanilla. In a large mixing bowl, combine the dry ingredients and mix on low speed just to blend. Add butter and the remaining sour cream, mix on low speed til dry ingredients are moistened; increase to medium, and beat for 1 1/2 minutes to aerate and develop the cake's structure. Scrape down the sides. Gradually add the egg mixture to batter in 3 batches, beating for 20 seconds after each addition; scrap down the sides. Scrape the batter into the fruit-lined skillet, smoothing evenly with a spatula; bake for 40-50 minutes, til golden brown and and the toothpick test comes out clean.
Run a small metal spatula around the sides and invert at once onto a serving plate. Leave the skillet in place one or two minutes before lifting it. If any fruit has stuck to the skillet, simply use a small spatula to place it back on cake.
Enjoy!
