Method
- Heat the oven to 350 F. Butter a 9 inch round cake pan, line the bottom with a circle of parchment, and lightly flour the sides, tapping out the excess.
- In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
- In the bowl of a stand mixer fitted with the whisk attachment, add the eggs and granulated sugar. Whip on medium-high for 4 to 5 minutes until the mixture is pale yellow, thick, and falls in a ribbon when you lift the whisk.
- With the mixer running on low, slowly stream in the olive oil in a thin, steady drizzle, taking about 1 minute. The batter should look glossy and emulsified.
- Add the lemon zest, lemon juice, and whole milk. Mix on low just until combined.
- Remove the bowl from the mixer. Sift the flour mixture over the wet ingredients in two additions, folding gently with a rubber spatula after each one until no streaks of flour remain. Do not overmix.
- Pour the batter into the prepared pan and smooth the top. Tap the pan once on the counter to release any large air bubbles.
- Bake on the center rack for 35 to 40 minutes, until the top is deeply golden, the cake is domed, and a tester inserted into the center comes out clean. The edges should be pulling away slightly from the pan.
- Cool the cake in the pan on a wire rack for 15 minutes, then run a thin knife around the edge, invert onto the rack, peel off the parchment, and turn right side up to cool completely, about 1 hour.
- While the cake cools, make the whipped mascarpone. In a clean mixer bowl, combine the cold mascarpone, cold heavy cream, powdered sugar, and vanilla extract. Whip on medium speed for 1 to 2 minutes, just until the mixture holds soft, billowy peaks. Do not overwhip or it will turn grainy.
- To serve, place the cooled cake on a serving plate and dust lightly with powdered sugar. Spoon generous clouds of the whipped mascarpone over the top, letting it drift toward the edges.
- Scatter the fresh mixed berries over the mascarpone, slice into wedges, and serve at once.
