Pineapple Upside Down Cake Doesn't Get Any Better Than This!

• 1 cup firmly packed dark brown sugar
• 12 cup unsalted butter
• 1 (20 ounce) can pineapple slices
• 1 12 cups all-purpose flour
• 6 tablespoons cake flour
• 6 tablespoons ground almonds (from ~2 oz. of whole almonds)
• 34 teaspoon baking powder
• 12 teaspoon salt
• 1 34 cups sugar
• 1 cup unsalted butter, at room temperature
• 4 large eggs
• 34 teaspoon vanilla extract
• 34 cup sour cream

1. Start by making the caramel topping.
2. Take brown sugar and butter and combine and melt in a saucepan on medium heat until sugar disolves and the mixture is bubbly.
3. This should take several minutes.
4. (After sugar melts, don't stir.)
5. Pour mixture into a 10-inch diameter stick-free cake pan with 2 inch high sides.
6. Arrange pineapple slices in a single layer on top of the caramel mixture.
7. You should be able to fit about 7 slices.
8. Preheat oven to 325 degrees F. Whisk the flours, almonds, baking powder and salt in a large mixing bowl.
9. In a separate bowl, use an electric mixer to beat the sugar and butter together until light and fluffy.
10. Add eggs, one at a time, beating after each addition.
11. Beat in the vanilla.
12. Add dry ingredients alternately with sour cream in 2 additions each, beating well after each addition.
13. Pour cake batter over caramel and pineapple in pan.
14. Bake cake until tester inserted into the center comes out clean, about 1 hour to 1 hour 15 minutes (mine was actually done in one hour, so check after one hour).
15. Turn cake out onto platter.
16. Serve warm or at room temperature.
17. BEWARE: some caramel might drip on the bottom of your oven while baking; I cleaned it up immediately after taking the cake out, scraping it off with a spatual--be careful!
18. You know how hard it is to get that caramel off when it hardens:).
