Prepare the Whipped Cream: In a large bowl, beat the heavy whipping cream, powdered sugar, and vanilla extract with an electric mixer on high speed until stiff peaks form. Be careful not to overbeat, or you’ll have butter!
Layer the Cake: In a large trifle dish or a glass bowl, create a layer of pound cake cubes at the bottom. You can trim the pieces to fit the shape of your dish.
Add Lemon Curd: Spread a generous layer of lemon curd over the pound cake. If your lemon curd is too thick, you can slightly thin it with a bit of lemon juice or water for easier spreading.
Layer Raspberries: Add a layer of fresh raspberries on top of the lemon curd. Save some berries for the final garnish.
Top with Whipped Cream: Spoon or pipe a layer of whipped cream over the raspberries, making sure to cover them completely.
Repeat: Continue layering cake, lemon curd, raspberries, and whipped cream until you’ve filled your dish. Typically, you’ll have two or three layers depending on your dish size.
Garnish: Finish with a final layer of whipped cream, and garnish with fresh raspberries and lemon zest. Refrigerate for at least 2 hours before serving to allow the flavors to meld.
