Before you start
Before starting, bring the butter, eggs, and milk to room temperature. Grease and flour two 9-inch round cake pans and line the bottoms with parchment paper for easy release. Set up a cooling rack. Grate the white chocolate into curls and set aside. Measure all ingredients and have them ready.
The mascarpone and heavy cream should be well chilled for whipping. Prepare the candied lemon peel by slicing it into thin strips. Have the fresh blueberries washed and dried. The blueberry preserves for the glaze should be at room temperature or gently warmed to make pouring easier.

Instructions
Bake and Prep
- Prepare the Sponge and White Chocolate CurlsHeat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. In a medium bowl, whisk together the flour, baking powder, and salt. In a large bowl, beat the butter and sugar until light and fluffy. Add the eggs one at a time, beating well after each, then stir in the vanilla. Alternately add the flour mixture and the milk, beginning and ending with the flour, until just combined.Look for The cakes are golden and spring back when pressed; the white chocolate curls are fluffy and ivory.Safe temperature 160°F (71°C) internal temperature (egg dishes)Tip For even layers, use a kitchen scale to divide the batter between the pans.
- Make the Blueberry CompoteIn a medium saucepan, combine the blueberries, lemon juice, and sugar. Cook over medium heat, stirring occasionally, until the berries burst and the mixture thickens, about 10 minutes. Remove from the heat and let cool slightly; the compote should be warm but not hot when assembling the cake.Look for The compote is thick and glossy, with visible berry pieces.Tip If the compote seems too thin, simmer a few extra minutes to reduce.
The sponge layers are golden and fragrant, and they have cooled completely on the rack. The white chocolate curls are fluffy and ivory. The blueberry compote is thick and bubbling, with visible berry pieces and a glossy sheen. The kitchen smells of vanilla and warm blueberries. Before moving on, ensure the cakes are level and the compote has cooled slightly but is still warm for assembly.
Whip and Assemble
- Whip the Earl Grey Honey Mascarpone CreamIn a large chilled bowl, combine the mascarpone, heavy cream, honey, and Earl Grey tea leaves. Beat with an electric mixer on medium-high speed until stiff peaks form, about 3 to 4 minutes. Be careful not to overbeat, or the cream will curdle. Refrigerate until ready to assemble.Look for The cream holds firm peaks and is pale ivory with specks of tea.Tip Chill the bowl and beaters for 10 minutes beforehand for a fluffier cream.
- Assemble the Cake LayersPlace one cooled sponge layer on a cake stand or serving plate. Spread a generous layer of the Earl Grey honey mascarpone cream over the top, then spoon the warm blueberry compote over the cream, spreading it gently to the edges. Place the second sponge layer on top. Use the remaining mascarpone cream to frost the top and sides of the cake, creating a smooth or swirled finish. Chill the assembled cake for 20 minutes to set the cream.Look for The layers are even and the cream is smooth; the compote peeks out at the edges.Tip Use an offset spatula for a clean, professional finish.
- Pour the Blueberry GlazeWarm the blueberry preserves in a small saucepan over low heat, stirring until smooth and pourable. Let cool slightly, then pour the glaze over the top of the chilled cake, allowing it to drip down the sides. Use a spatula to spread it evenly if needed.Look for The glaze is glossy and violet, dripping elegantly over the cream.Tip If the glaze is too thick, add a teaspoon of water to loosen it.
The mascarpone cream is thick, airy, and holds stiff peaks. The cake is assembled with even layers of cream and compote, and the sides are frosted smoothly. The assembled cake has been chilled for 20 minutes, so the cream is set and firm. The glaze is warm and pourable, and when poured, it creates a glossy, violet cascade down the sides. The cake looks elegant and polished.
Garnish and Serve
- Garnish and ServeGarnish the top of the cake with fresh blueberries, white chocolate curls, and sliced candied lemon peel. For serving, slice a thick triangular wedge with a sharp knife and lift it onto a metal cake server. Serve immediately.Look for The cake is garnished with colorful berries, curls, and lemon peel.Tip Dip the knife in hot water and wipe it clean between slices for neat cuts.
The top of the cake is adorned with fresh blueberries, white chocolate curls, and candied lemon peel. The first slice is cut cleanly, revealing tall, distinct layers of sponge, cream, and compote.
The slice is lifted with a metal cake server and placed on a plate, ready to serve. The presentation is beautiful and appetizing, with the glaze glistening and the garnishes adding color and texture.
Common mistakes
One common mistake is overbeating the mascarpone cream, which can cause it to become grainy or curdle. Beat just until stiff peaks form and stop immediately. Another issue is overmixing the cake batter, leading to a dense, tough sponge. Mix only until the flour is incorporated.
When pouring the glaze, make sure it is not too hot or it will melt the cream; let it cool slightly but still be pourable. Also, ensure the cake layers are completely cool before frosting; warm layers will cause the cream to slide. Finally, use a sharp knife and wipe it between cuts for clean slices.
How to tell it’s done
The cake is done when a toothpick inserted into the center comes out clean or with a few moist crumbs. The top should be golden brown and spring back when lightly pressed. The internal temperature of the cake should read 200°F (93°C) in the center.
The mascarpone cream is whipped to stiff peaks that hold their shape on the spatula. The compote is thick and coats the back of a spoon. The glaze pours smoothly and sets to a glossy finish on the chilled cake. The assembled cake should be chilled until the cream is firm enough to slice cleanly.
