If you don't have a high-sided 10-inch cake pan, you might try making this in a springform pan. Line the inside with foil so the caramel doesn't leak, and bake on a rimmed baking sheet just in case it does. (Thanks to a tip in the comments!)
- 1 cup of firmly packed dark brown sugar
- 1/2 cup unsalted butter
- 1 can (20 oz) of pineapple slices
- 1 1/2 cups all purpose flour
- 6 Tbsp cake flour
- 6 Tbsp of ground almonds (from about 2 oz of whole almonds)
- 3/4 teaspoon baking powder
- 1/2 teaspoon salt
- 1 3/4 cups of sugar
- 1 cup (2 sticks) unsalted butter at room temperature
- 4 eggs
- 3/4 teaspoon vanilla extract
- 3/4 cup sour cream
1 Start by making the caramel topping. Take brown sugar and butter and combine and melt in a saucepan on medium heat until sugar dissolves and the mixture is bubbly, this should take several minutes. (After sugar melts, don't stir.) Pour mixture into a 10 inch diameter stick-free cake pan with 2 inch high sides. Arrange pineapple slices in a single layer ontop of the caramel mixture.
2 Preheat oven to 325° F. Whisk the flours, ground almonds, baking powder, and salt in a large mixing bowl. In a separate bowl, use an electric mixer to beat the sugar and butter together until light. Add eggs one at a time, beating after each addition. Beat in the vanilla. Add dry ingredients alternately with sour cream in 2 additions each, beating well after each addition. Pour cake batter over caramel and pineapple in pan.
3 Bake cake until tester inserted into the center comes out clean, about 1 hour to 1 hour 15 minutes. Cool cake in pan on a rack for 10 minutes. Turn cake out onto a platter. Serve warm or at room temperature.
Makes 12 to 14 servings.
* Note an alternative topping: 2 cups granulated sugar, 1/2 cup water, 1/4 cup butter. Combine sugar and water in a medium saucepan. Heat on medium until all sugar is dissolved. Increase heat to medium high and bring to a boil. Boil until syrup becomes warm amber in color (about 10 minutes). Add 1/4 cup butter, carefully as it will foam up a bit. Swirl the pan so that the butter is all incorporated, stirring with a wooden spoon if necessary. Remove from heat and pour out into cake pan. Continue with recipe as noted.
