To prepare a white chocolate and raspberry tart recipe, first you need to prepare the ingredients for the tart. First, you'll need the following ingredients: Preheat the oven to 375?F (190?C) Grease and flour two 9-inch tart pans. Set aside. Using an electric mixer, cream the butter and sugar on medium speed until light and fluffy. Add the eggs and vanilla and beat until combined. Gradually beat in the flour mixture, scraping down the sides of the bowl as needed. Pour the batter into the prepared tart shells and bake for 20 to 25 minutes, or until the crust is golden brown. Remove from oven and let cool before serving.
