Rows of halved pineapple rings create an unexpected geometric pattern on this upside-down cake by Allrecipes Editor in Chief Nichole Aksamit. Her secret to a toothsome crumb and a not-too-sweet cake? Almond flour and sour cream in the batter. Serve with unsweetened whipped cream, if desired.

Stages of cooking
-
Preheat the oven to 325 degrees F (165 degrees C). Coat a 9-inch square baking pan with cooking spray.
-
Melt 1/2 cup butter in a saucepan over medium-high heat. Add 1 cup plus 2 tablespoons brown sugar, stirring until just dissolved. Cook until bubbling, about 2 minutes. Pour into the prepared pan.
-
Arrange pineapple in a single layer of diagonal rows over the brown sugar mixture.
-
Whisk together both flours, baking powder, cornstarch, and salt in a bowl.
-
Beat together white sugar and 1 cup butter in a large bowl with an electric mixer at medium speed until light and fluffy, 3 to 4 minutes. Beat in eggs, one at a time, then stir in vanilla. Beat in 1/2 of the flour mixture, followed by 1/2 of the sour cream; repeat.
-
Spread batter over pineapple in the pan.
-
Bake in the preheated oven until a toothpick inserted into the center comes out clean, 65 to 70 minutes.
-
Cool in the pan on a wire rack for 10 minutes, then invert onto a platter.
