Prep pan: Grease an 8x2-inch cake pan with cooking spray and line with parchment paper.

Flour mixture: In a small bowl mix together flour, baking powder, baking soda and salt. Set aside.

Wet mixture: In a large bowl mix orange zest and granulated sugar together until well combined. Stir in olive oil. Add eggs, one at a time, mixing well after each addition. Add milk, vanilla and almond extract. Stir in flour mixture and mix until combined.

Bake: Pour batter into prepared pan and bake for 40-50 minutes at 350 degrees, or until a toothpick inserted comes out clean. Allow to cool before frosting.

Whipped Mascarpone Frosting: Add mascarpone, powdered sugar, whipping cream and zest to a bowl and beat with electric mixers (or use a food processor) until very smooth and fluffy. Spread over cooled cake. Garnish with candied orange slices and sprigs of fresh mint, or rosemary.
