Preheat oven to 350℉. Spray a bundt pan with baking cooking spray. In a large bowl, combine the cake flour, baking powder, baking soda, salt, and sugar. Mix well.
In another large bowl, combine the ricotta cheese, eggs, vanilla extract, blood orange zest, olive oil, blood orange juice, and milk. Mix well.
Add the dry ingredients to the wet ingredients and stir well to combine. Pour mixture into a prepared bundt pan. Bake for 50-55 minutes or until a toothpick when inserted comes out clean. Allow cake to cool in the pan for about 10 minutes, then transfer to a wire rack to cool completely.
In a small bowl, combine all ingredients and whisk to combine until the mixture is smooth. Pour over the cooled cake. Garnish with blood orange slices.
