Preheat oven to 350°F. Butter a 9″ pan.
In a large mixing bowl, whisk together the olive oil, eggs, and sugar. No need to use a mixer.
Add the vanilla, blood orange zest and juice. Whisk briefly to combine.
Sift together the salt, baking powder, baking soda, and flour. Alternating with the milk, add the dry ingredients to the wet ingredients in a couple of batches.
Pour the batter into the pan. Sprinkle 2 tbsp of granulated sugar evenly over the top.
Bake for 50-55 minutes. The cake should be risen and starting to turn a bit golden brown on the top.
Remove from the oven and allow to cool for about 10 minutes in the pan and then cool completely on a baking rack.
When cool, dust the top with powdered sugar, if desired.
