A festive, no-bake dessert perfect for the 4th of July, this trifle features patriotic red, white, and blue layers. The dessert is built in a large trifle bowl by layering cubes of store-bought angel food cake, creamy white chocolate instant pudding, fresh strawberries, fresh blueberries, and thawed whipped topping. It’s a simple-to-assemble but impressive-looking centerpiece that is chilled before serving.
