Bright, Citrusy orange upside down cake is dense, moist and have wonderful orange flavor. This cake is a real show-stopper, the perfect bake for Mother's Day.
2tablespoons orange zest (zest of 1 orange - any type of orange)
1/2cupfreshly squeezed orange juice (juice of 1 orange- any type of orange)
1teaspoon vanilla extract
Instructions
Adjust oven rack to middle position and preheat oven to 350 degrees Fahrenheit.
Remove the skin from 2 oranges. Using a sharp knife or serrated knife, slice one navel orange and cara cara orange crosswise 1/4 inch thick, and picking out and discarding the seeds as you go. Set aside.
Grease 9-inch round cake pan, and line bottom with parchment paper - for easier removal. Pour melted butter over the bottom of prepared pan and swirl to coat bottom. Sprinkle the brown sugar evenly over the melted butter.
Arrange orange slices: Starting in the centre of the pan, layer the orange slices on top of the sugar, overlapping them in a circular pattern, until bottom is completely covered. Set a side.
Place the sifted flour, baking powder and salt in a medium bowl and whisk until the ingredients are well combined.
Add the sugar and eggs to the bowl of a stand mixer. Beat the sugar and egg mixture on high speed until light and fluffy, about 3 minutes. Scrape down the sides of the bowl. Add the oil gradually, vanilla extract, then add orange juice, orange zest and mix at low speed until well combined.
Add the dry ingredients in two parts and whisk until just combined. Even if using a stand mixer, I usually do the last mixing by hand (using rubber spatula), so it doesn't get over-mixed; scrape the sides and bottom of the bowl. Stir just until the last of the flour is barely incorporated into the batter.
Gently pour the batter over the orange slices and smooth the top with an offset spatula (being sure not to disturb your beautiful orange design). Bake for about 30 to 35 minutes or until deep golden brown and toothpick inserted in centre come out mostly clean.
Remove from oven and let cake cool in pan on wire rack for 15 to 20 minutes. Gently run a knife around edges of the pan to loosen cake, then invert cake onto large plate or platter. Peel the parchment paper away from the oranges. Allow the cake to cool completely before slicing and serving. Serve the cake at room temperature. Use a sharp knife to cut through the oranges and cake. Enjoy!
