Recipe by Tom Douglas. The icing for this cake is not a classic fondant, but an almost transparent powdered sugar glaze flecked with rosemary leaves and lemon zest. The rosemary is blanched first, to remove some of its pungency. For a less dressy cake, you could omit the fondant. Simply brush the cake with the lemon syrup and serve with sliced fresh figs or small bunches of grapes.
FOR THE CAKE
- 354.88 ml all-purpose flour
- 177.44 ml medium-ground yellow cornmeal
- 14.79 ml finely chopped fresh rosemary
- 14.79 ml grated lemon, zest of
- 4.92 ml baking powder
- 1.23 ml kosher salt
- 158.51 ml mascarpone
- 4 large eggs
- 314.66 ml sugar
- 118.32 ml unsalted butter, melted,plus more for buttering the pan
For the lemon syrup
- 118.29 ml fresh lemon juice
- 78.07 ml sugar
For the lemon fondant
- 14.79 ml rosemary (stripped from the stem, not chopped)
- 354.88 ml powdered sugar, sifted
- 59.14 ml heavy cream
- 29.58 ml fresh lemon juice
- 4.92 ml grated lemon, zest of
- Preheat the oven to 350°F.
- Butter a 9-inch cake pan, line it with a circle of parchment paper, and butter the paper.
- In a bowl, combine the flour, cornmeal, rosemary, zest, baking powder, and salt.
- In a large bowl, briefly whisk the mascarpone to loosen it.
- Add the eggs one at a time, whisking to combine.
- Add the sugar and whisk until smooth.
- Using a rubber spatula, fold the dry ingredients, in two batches, into the wet ingredients, mixing until smooth.
- Stir in the butter.
- Scrape the cake batter into the prepared pan and bake until a skewer comes out clean, about 40 minutes.
- While the cake is baking, make the lemon syrup.
- Combine the lemon juice and the sugar in a small saucepan over medium heat and cook a few minutes, stirring occasionally, until the sugar dissolves.
- Remove from the heat.
- Allow the cake pan to cool on a rack for 5 minutes before unmolding.
- To unmold, run a small knife around the cake.
- Place an inverted plate over the cake pan and, protecting your hands with a kitchen towel, invert the whole thing.
- The cake should slide right out onto the plate.
- Peel off the parchment paper, then place a 9-inch cardboard circle or an inverted plate over the cake and, again, invert the whole thing.
- Remove the top plate and the cake will be right side up.
- With a wooden skewer, poke a few dozen holes all over the top of the cake.
- While the cake is still warm, brush the cake with the lemon syrup.
- Continue brushing for several minutes, giving the syrup time to sink into the cake, until you've used all or most of the syrup.
- Allow the cake to cool.
- To make the lemon fondant, bring a small saucepan of water to a boil.
- Add the rosemary leaves and blanch them for one minute.
- Scoop out the rosemary leaves with a small sieve and drop them immediately into a small bowl of ice water.
- Drain, and spread the rosemary leaves on a paper towel to dry.
- In a bowl, whisk the powdered sugar, cream, and lemon juice until smooth, then whisk in the blanched rosemary and the zest.
- When the cake is completely cool, transfer it to a rack set over a baking sheet.
- (If your cake is not on a cardboard circle, use a wide spatula to transfer it.) Pour the fondant over the top of the cake and allow it to drip off the sides.
- You can gently tilt the cardboard circle or the wire rack back and forth to encourage the glaze to completely flow over the top of the cake.
- While the glaze is still wet, transfer the cake to a cake plate.
- Allow the fondant to dry, an hour or more, before serving the cake.
- (If you allow the glaze to dry before you transfer it, the glaze may crack a bit, unless you are transferring it on a cardboard circle.) Because this cake is quite moist, you can make it one day ahead.
- After the cake is brushed with the syrup, allow it to cool completely, then wrap it tightly in plastic wrap, and leave it at room temperature.
- A few hours before you're ready to serve the cake, make the fondant and glaze the cake.
Loved this! Yes, the cake was hearty, but perfect to end a light spring meal. Loved the rosemary/lemon combo. Thanks! —
The rosemary and lemon combination, which I love in savory dishes (like roasted chicken with lemon and rosemary) works really well in a desert too! The rosemary gives it a subtle flavor and aroma and looks really pretty in the fodant. THe people I made it for commented on the unique flavors and really liked it. I found the cake a little heartier than I expected. I would recommend it as a brunch cake instead of as an after-dinner dessert. Great recipe!
