Preheat the oven & prepare the pan: Preheat oven to 180ºC (356ºF). Line an 8-inch round baking pan with parchment paper and set aside. Note: If using a non-stick pan, liberally grease it with melted butter and dust it with flour for smooth cake sides.
Beat the sugar, eggs, and lemon: In a large mixing bowl, add sugar, eggs, lemon zest, and lemon juice. Using electric hand beaters, beat on low-medium speed for 30 seconds until well combined. Scrape down the sides if needed.
3/4 cup granulated sugar, 2 large eggs, , 2 Tbsp lemon zest,, 2 Tbsp freshly squeezed lemon juice,
Emulsify the olive oil: With the beater running on low-medium speed, slowly drizzle in the olive oil in a steady stream while beating for about 50 seconds until fully emulsified.
3/4 cup extra virgin olive oil
Add the milk and vanilla: Pour in the milk and vanilla extract. Beat for 15 seconds until well combined. Scrape down the sides if needed.
3/4 cup whole milk, , 1 tsp vanilla extract
Incorporate dry ingredients: Add flour, baking powder, salt and the finely chopped rosemary. Beat for about 15 seconds, just until incorporated into a smooth batter. Do not over-mix. Scrape down the sides.
1 1/2 cups (225g) all-purpose flour,, 1 1/2 tsp baking powder, 1/2 tsp salt, 2 Tbsp fresh rosemary sprigs,
Transfer batter to the pan: Pour the batter into the prepared baking pan, smoothing out the top.
Bake the cake: Bake for 30-35 minutes or until a toothpick inserted into the middle comes out clean and the top is lightly golden.
