PEACH AND BLUEBERRY UPSIDE DOWN CAKE RECIPES

Steps:

• Preheat oven to 350°.
• Melt 1 tablespoon butter in a 10-inch cast-iron skillet over medium heat; sprinkle brown sugar evenly in pan. Remove from heat. Arrange peach slices in a circle in center of pan; scatter blueberries and raspberries evenly around peach slices. Set aside.
• Place remaining 1/4 cup butter and granulated sugar in a large bowl; beat with a mixer at medium speed until well blended. Add rind, juice, egg whites, and egg; beat well. Lightly spoon flour into dry measuring cups; level with a knife. Combine flour, baking powder, baking soda, and salt, stirring well with a whisk. Add flour mixture and buttermilk alternately to sugar mixture, beginning and ending with flour mixture.
• Carefully spoon batter over fruit mixture. Bake at 350° for 35 minutes or until a wooden pick inserted in the center comes out clean. Run a knife around the edges of pan. Cool cake completely in pan on a wire rack. Place a plate upside down over skillet; carefully invert onto plate.

Steps:

• Heat oven to 350 degrees. Grease and line base and sides of a 9-inch-square cake pan with baking parchment, and grease the parchment. Sprinkle 1/3 cup sugar over base of pan, and cover evenly with blueberries.
• In a large mixing bowl, combine eggs, 1 cup sugar and orange zest. Whisk until pale and thick. Add orange juice and oil, and whisk until blended. In a separate bowl, whisk together polenta, flour, baking powder and salt. Add flour mixture to egg mixture, whisking until smooth. Pour into prepared pan.
• Bake for about 45 to 55 minutes, until golden brown and springy to the touch, and a toothpick inserted near the center comes out clean. Cool cake on a rack for about 5 minutes. Carefully invert cake onto a serving plate, and slowly peel off parchment paper. Serve warm or at room temperature.
