Ingredients
Topping
- Nonstick cooking spray
- 2 tablespoons granulated sugar
- 1 tablespoon all-purpose flour
- 1 tablespoon sesame seeds
Batter
- 1 1/2 cups granulated sugar
- 1/2 cup (1 stick) unsalted butter, at room temperature
- 1/4 cup vegetable oil
- 1 cup sifted all-purpose flour
- 1/2 cup white rice flour
- 1 1/2 teaspoons baking powder
- 3 large eggs, at room temperature
- 1 cup milk, lukewarm
- 1 cup grated Parmesan (about 4 ounces)
- 1/4 cup raspberry jam
Sprinkle
- 1/2 cup powdered sugar
- Heaping 1/4 cup freeze-dried raspberries
- 2 tablespoons sesame seeds, toasted
Directions
- For the topping: Preheat the oven to 350°F. Spray a 9-inch springform pan with nonstick cooking spray and place on a rimmed baking sheet.
- Mix the granulated sugar, flour, and sesame seeds together in a small bowl. Powder the bottom and the sides of the springform pan with some of the sesame mixture and reserve the rest.
- For the batter: Beat together the granulated sugar, butter, and oil in a stand mixer fitted with the paddle attachment—or with an electric mixer—until fluffy, about 2 minutes. Add the eggs one at a time, mixing well after each addition. Mix the Parmesan and milk in a liquid measuring cup. Whisk the all-purpose and rice flours and baking powder together in a medium bowl. Add them alternately with the milk mixture, beginning and ending with the flour. Stir well after each addition.
- Pour the batter into the prepared pan. Dollop the raspberry jam and spread in a swirl pattern on the top of the batter with the spoon.
- Sprinkle the remaining sesame seed mixture in an even layer over the batter.
- Bake until the cake is golden brown and is mostly set, but still jiggles in the middle, about 45 minutes. Remove from the oven. Let it cool slightly on a wire rack, then while still warm, run a sharp knife around the sides and remove the ring of the pan. Let cool completely before decorating or slicing.
- While the cake is cooling, add the powdered sugar, raspberries, and toasted sesame seeds to a food processor. Blitz until it is a fine powder.
- When you are ready to serve, sift the raspberry powder onto the cake using a fine-mesh sieve. Cut into wedges and serve at room temperature.
