Blood Orange Upside Down Cake Recipe

Preheat oven to 350 degrees F and coat a 10” cake pan with nonstick cooking spray.
Evenly scatter the raw sugar over the bottom of the cake pan and place the orange slices on top.
In a large bowl whisk together the flour, sugar, baking powder, baking soda, and salt.
In a separate bowl, whisk together the eggs, buttermilk, melted butter, orange zest and orange juice.
Pour the wet ingredients in with the dry ingredients and mix with a rubber spatula until nearly combined. Some dry spots OK as you do not want to overmix the batter.
Pour the batter over the oranges and bake for approximately 35 minutes, or until the sides start pulling away from the pan and a toothpick inserted in the middle comes out clean.
Transfer make to a wire rack to cook for 5 minutes before inverting over a large plate and gently releasing from the pan.
