Blueberry Earl Grey Honey Mascarpone Layer Cake with White Chocolate

A layer cake that looks as elegant as it tastes, with pale honey mascarpone cream, a deep purple blueberry layer and a glossy lavender glaze. Every element is simple to prepare, and the finished cake slices cleanly for a dinner party or celebration.

This blueberry Earl Grey honey mascarpone layer cake brings together bright blueberries, the floral note of Earl Grey tea and a smooth, lightly sweet cream. Lemon peel adds freshness to the fruit, while white chocolate gives both the glaze and the crown a soft, delicate sweetness.

The cake is built inside an acetate ring, so the sides stay straight and the layers stay neat. Set aside time for chilling between steps, because the cake needs to firm up before it is glazed and sliced. The result is a dessert with clear layers, a set glossy top and a crown of fresh berries and white chocolate curls.

Ingredients

Why this recipe works

The mascarpone and cream base stays stable when it is chilled between layers. Mascarpone is rich and fairly firm, so whipping it briefly with cold cream gives a spreadable texture that holds its shape on the cake without becoming heavy.

Steeping the tea in the cream lets the Earl Grey flavor spread evenly through the whole cream instead of sitting in pockets.

The compote is cooked down with sugar and lemon juice and then thickened with cornstarch, so it spreads into a glossy, stable layer rather than running into the cream.

Cooling it fully before assembly is essential, because warm fruit would soften the mascarpone and blur the sharp line between the layers. The lemon zest lifts the blueberry flavor and keeps the sweetness in balance.

Notes and substitutions

Use a cold block of white chocolate for grating, and a fine grater so the curls stay soft and delicate. A good quality white chocolate with a clean, creamy flavor makes the glaze smooth and the garnish pleasant to eat. Keep the cream and mascarpone cold until the moment you use them, since warm dairy will loosen the texture quickly.

An 8-inch acetate cake ring gives the cleanest sides, and an offset spatula helps you spread each layer evenly. The round sponge layer can be bought or made a day ahead, so the main work is the cream, compote and finish.

Frozen blueberries work well for the compote if fresh berries are out of season, and omitting the butterfly pea powder still gives a pale, attractive glaze.

• butterfly pea flower powder: omit it for a pale cream glaze without the lavender tint
• loose Earl Grey tea leaves: 2 Earl Grey tea bags, snipped open
• fresh blueberries: frozen blueberries, thawed and drained for the compote
