For the Cake:

- In a stand mixer, cream butter, sugar, and lemon zest until pale and fluffy. Add olive oil and mix until smooth.
- Beat in eggs one at a time until fully incorporated.
- Stir in yogurt, milk, lemon juice, and vanilla until smooth.
- Fold in the dry mixture gently until just combined — do not overmix.
- Pour batter into pan and bake 30–35 minutes, until a toothpick inserted comes out clean.
- Cool 10 minutes in pan, then transfer to a wire rack.
For the Frosting:
- Beat butter and cream cheese together until smooth and creamy (2–3 minutes).
- Gradually add powdered sugar, starting on low, until combined.
- Add vanilla, salt, and optional lemon juice/zest. Beat on medium-high 2 minutes until fluffy.
Assembly:
