This delicious cake uses Earl Grey tea leaves as an ingredient in the cake batter and the mascarpone cream topping. Earl Grey is a fragrant black tea flavored with bergamot oranges. Bergamot oranges are grown in Southern Italy with the juice being used in making candy, liqueurs, and pastries. The essential oil extracted from the rind is used to flavor black tea, thus creating Earl Grey. I did not realize this beloved English tea has roots in Italy.
The cake is topped with soft peaks of whipped mascarpone cream, and the cake has bits of chopped chocolate in every bite. To finish the cake, I like to garnish with additional chocolate curls over the peaks of cream. Wonderful with your favorite cup of tea, or maybe an espresso.
Frosting Ingredients
3/4 cup heavy cream, divided
2 teaspoons loose Earl Grey tea
1/4 cup powdered sugar
1/2 cup mascarpone cream cheese, room temperature
Cake Ingredients
1 1/2 cups all-purpose flour
1 tablespoon loose Earl Grey tea
1 teaspoon baking powder
1/2 teaspoon fine sea salt
1/2 cup (1 stick) unsalted butter, room temperature
1 cup granulated sugar
2 teaspoons fresh grated orange zest, from 1 orange
2 large eggs, room temperature
1/2 cup whole milk, room temperature
1/3 cup chopped bittersweet chocolate, such as Ghirardelli
Additional chocolate for topping the finished cake
For the Frosting: In a small saucepan, bring 1/2 cup heavy cream to a simmer over medium heat. Remove from the heat, stir in the tea and let stand for 30-40 minutes. Strain the tea using a fine-mesh strainer into a small bowl, discarding the tea leaves. Chill the tea-cream for about an hour, or overnight.
For the Cake: Preheat the oven to 350 degrees. Use additional butter to grease an 8-inch round cake pan and line with parchment paper. In a medium bowl, combine the flour, tea, baking powder, and salt, whisking together. Set aside.
In the bowl of a stand mixer, add the butter and sugar mixing until light and fluffy, about 3 minutes. Add in the orange zest, mix to combine. Add the eggs one at a time, mixing until combined, scraping down the sides of the bowl as needed. With the mixer off, add in the flour mixture, mixing on low until just combined. Mix in the milk to combine. Use a rubber spatula to fold in the chopped chocolate. Transfer the batter to the prepared cake pan. Bake in the oven for 30 to 35 minutes until a toothpick inserted into the center comes out with just a few crumbs attached. Cool the cake in the pan on a rack for 15 minutes. Remove the cake from the pan to cool on the rack.
Finish the frosting: Add the remaining 1/4 cup of heavy cream, the powdered sugar, and the tea cream to a clean mixing bowl. With an electric mixer, whisk until medium peaks form. Add the mascarpone cheese and whisk until stiff peaks form. Transfer the frosting to the cake, smoothing and swirling to cover the top of the cake.
Top the frosted cake with chocolate curls shaved from the additional chocolate. Store the cake, and leftovers, in the fridge, letting the cake come to room temperature before serving.
