Tips for success
Chill the assembled cake between each cream layer, and again after the glaze, so the layers stay crisp and the sides stay straight. A short chill gives a cleaner cut than slicing a cake that is still soft in the middle. Keep the offset spatula warm by dipping it in hot water and wiping it dry, which helps glide the cream smoothly and gives a polished finish on the sides.
Grate the white chocolate just before decorating, since the soft curls can soften and lose their shape if they sit out for long. Store any remaining grated chocolate in a covered container in the refrigerator until you need it. Add the blueberries and the crown at the last moment so they stay bright and plump rather than bleeding color into the glaze.
Variations
- Lemon-free compote: Leave out the lemon zest and juice from the blueberry compote and add a pinch of salt instead. This gives a softer, more purely berry flavor that suits guests who prefer less citrus in the dessert.
- Vanilla cream: Add half a teaspoon of vanilla extract to the mascarpone and cream before whipping. The vanilla rounds out the honey and tea, giving the cream a warmer, more familiar sweetness.
- Raspberry swap: Replace the blueberries in the compote with raspberries and keep the crown of blueberries for color. The brighter berry flavor pairs well with the lemon and honey in the cream.
- Plain white glaze: Skip the butterfly pea powder and tint the glaze with a few drops of a food-safe color, or keep it creamy white. This version keeps the cake pale and gives the crown of blueberries more contrast.
Storage and make-ahead
- Fridge
- Keep the cake refrigerated, covered loosely, for up to 3 days to hold its shape and flavor well.
Keep the cake refrigerated in its ring or on a board covered loosely with plastic wrap, so the surface does not absorb odors from the refrigerator. Store it away from strong-smelling foods, since mascarpone and cream pick up flavors easily.
The cake keeps well for up to 3 days when chilled, and the blueberry compote and glaze hold their texture during that time. Slice only the portion you plan to serve, and cover the cut face with plastic wrap to keep the layers from drying. Return any leftovers to the refrigerator within two hours of serving.
Prepare the components up to two days before serving to make assembly easy. Make the blueberry compote, cool it fully and store it in a covered container in the refrigerator. Infuse the Earl Grey cream and keep it chilled, then whip the mascarpone cream just before assembling.
The sponge layer can be bought or made a day ahead and wrapped tightly at room temperature. Grate the white chocolate and keep the curls in a covered container, away from humidity. Assemble and glaze the cake on the day you plan to serve it, adding the crown of berries and curls last so the garnish looks fresh.
Serving ideas
Serve the cake chilled, with a thin slice cut using a warm knife for clean edges. Each slice shows the sponge, the blueberry compote and the pale honey cream in distinct layers, so cut through the center for the best view.
Pair the slices with a cup of hot tea, which echoes the Earl Grey in the cream and makes the flavors feel connected. A few extra blueberries on the side of each plate add color and a fresh contrast to the rich cream.
For a special occasion, present the cake whole on a flat serving board with the crown of blueberries and white chocolate curls facing up. Let guests see the layers by slicing at the table, and keep a small offset spatula nearby to lift each slice.
The cake holds well for a relaxed gathering because it is served cold, and the glaze and garnish stay neat until the last piece is taken.

Blueberry Earl Grey Honey Mascarpone Layer Cake with White Chocolate

Ingredients
- 1 round sponge cake layer, store-bought or made ahead
- 2 cups fresh blueberries, divided
- 1 lemon, for zest and juice
- 2 tsp loose Earl Grey tea leaves
- 16 oz mascarpone cheese, cold
- 1 cup heavy cream, cold
- 1/3 cup honey, plus more for the glaze
- 1/4 cup granulated sugar
- 1 tsp cornstarch mixed with 1 tbsp water
- 3 oz white chocolate, plus extra block for grating and pieces
- 1 cup confectioners' sugar
- 1/4 tsp butterfly pea flower powder, for a lavender tint
Instructions
- Set the blueberries aside. Cut thin strips of peel from the lemon, avoiding the white pith, then pull them into curled zest with your fingers. Steep the loose Earl Grey leaves in the warm heavy cream for 10 minutes, then strain.
- Combine 1 1/2 cups of the blueberries, the sugar, and the lemon juice in a small saucepan. Simmer over medium heat until the berries burst, about 8 minutes. Stir in the cornstarch slurry, cook 1 minute more, then cool completely.
- Hold the block of white chocolate over the cutting board and grate it with a fine microplane-style grater. Collect the soft white curls and shavings, then chop a few pieces for the crown. Keep the curls cool until serving.
- Beat the cold mascarpone with the honey until smooth. Add the tea-infused cream in a slow stream and whip to soft peaks, about 2 minutes. Keep the cream chilled until assembly.
- Place the sponge layer inside the acetate ring on a board. Spread a thin, even coat of the mascarpone honey cream over the cake. Spoon the blueberry compote into the center and spread it outward with a spoon, leaving a border.
- Spread a second layer of cream over the fruit, smoothing it level with an offset spatula. Add the remaining cream over the top and sides so the layers are covered. Chill the cake in the ring until the cream is firm.
- Melt the 3 oz white chocolate with 2 tablespoons of heavy cream, stirring until smooth. Whisk in the confectioners' sugar, a spoonful of honey and the butterfly pea powder for a lavender tint. Cool slightly until pourable.
- Pour the glaze over the top of the chilled cake and let it run down the sides. Chill until the glaze sets, then crown the top with the remaining fresh blueberries, grated white chocolate curls and chopped white chocolate pieces.
- Remove the acetate ring carefully. Lift the cake onto a serving board with an offset spatula, keeping the layered interior visible. Slice with a warm knife and serve chilled.
