Gather all your ingredients and tools, including a large mixing bowl, saucepan, spatula, trifle bowl, and whisk.
Place your berries in a saucepan, sprinkle with cinnamon and lemon zest, then simmer over medium heat until the berries release their juices and become fragrant, about 5-7 minutes. Let the mixture cool completely.
Crush the ladyfingers or sponge cake into small pieces, about the size of a walnut, to help them soak up the custard and layer easily.
Pour the vanilla custard into a large bowl and whisk until smooth and slightly thickened, about 1-2 minutes.
Start assembling your trifle by placing a layer of crushed ladyfingers at the bottom of your glass bowl, pressing lightly to settle.
Spoon a generous layer of custard over the ladyfingers, smoothing with a spatula for an even surface.
Spread a layer of cooled berry compote over the custard, distributing the mixture evenly for vibrant color and flavor.
Repeat the layers—ladyfingers, custard, and berries—until the bowl is nearly full, finishing with a layer of berries on top.
Top the assembled trifle with softly whipped cream or mascarpone, spreading gently to cover the surface.
Decorate with small pieces of candied ginger or sprigs of fresh mint for a festive touch and extra flavor.
Refrigerate the trifle for at least 2 hours to allow the flavors to meld and the layers to set. Serve chilled and enjoy a delightful, colorful holiday dessert.
