Preheat oven to 350°. Line a 9-inch springform pan with parchment paper and spray with cooking spray.
In a large bowl, whisk flour, sugar, baking powder, and salt. Set aside.
In another bowl, whisk eggs, ricotta, orange zest, orange juice, and vanilla.
Add the egg mixture into the dry ingredients and stir until blended.
Add the browned butter and fold until combined.
Gently fold in raspberries. I save some to decorate the top of the cake.
Pour batter into pan and spread evenly. Top with reserved raspberries, orange slices, pistachios, and sanding sugar.
Bake for 50 to 60 minutes or until a toothpick comes out clean.
