Instructions
to make the cake
- preheat oven to 375°F. lightly grease 2 9″ cake pans with olive oil or butter. sift together flour, sugar, salt, baking soda, and baking powder and set aside.
- in the bowl of a stand mixer with the whisk attachment, beat eggs on medium speed. slowly pour in olive oil and continue whisking until mixture thickens slightly, 2 to 3 minutes. pour in milk and orange juice and mix until just combined. add the orange zest. add dry ingredients on low speed until just combined, about 30 seconds. use a rubber spatula to scrape bowl to ensure all dry ingredients are incorporated. batter will look similar to pancake batter.
- pour batter into prepared pan. bake until cake begins to dome, about 30 minutes. rotate pan and continue baking until top is golden brown and an inserted toothpick comes out clean, 30 to 35 minutes. cool cake at least 2 hours before unmolding.
to make the frosting
- using a stand mixer with the paddle attachment (or handheld mixer) beat butter on medium speed until creamy.
- add cream cheese and vanilla, beat until fully incorporated. gradually increase mixer speed to high and continue beating until light and fluffy, scraping down the sides of bowl as necessary with rubber spatula.
- gradually add 4 cups of confectioners’ sugar, beating on low speed until well combined. add additional confectioners’ sugar until desired consistency for spreading and level of sweetness is reached.
- beat on high speed until well combined and smooth while scraping down sides of bowl as necessary, about 1 to 2 minutes. before frosting cake layers, you can re-beat buttercream to ensure smoothness.
