Preheat the oven to 180 C. or 350 F.
Prepare a 10-inch spring form pan by lightly coating with an oiled paper towel then dusting with flour
With a mixer with a whisk attachment beat eggs and sugar until pale in colour.
Add the orange zest, orange juice, olive oil, vanilla and cream and whisk until combines.
Switch to a paddle attachment. Add the salt, then alternating with flour and baking powder, add the remaining dry ingredients while mixing on medium speed until just incorporated.
Using a spatula, scrap into the prepared pan. Tap the pan on the counter to remove bubbles.
Bake in the preheated oven approximately 40 minutes or until golden and a toothpick comes out clean.
Cool on a rack before removing outside of the spring form pan. Dust with icing sugar for a snack. To dress up as dessert, add a dollop of whipped cream and fresh berries! Enjoy!
