Patriotic Berry Trifle

Once the cake has been baked and cooled, add heavy whipping cream, powdered sugar and vanilla into a larger mixer bowl. Whip on high speed until stiff peaks form.
Layer the Trifle Dish:
Start with a layer of cake chunks on the bottom, then add half of the fresh, chopped strawberries and blueberries and half of the whip cream.
Add a second layer of cake, fruit and cream.
For a decorative finishing touch, pipe some whipped cream swirls on top and garnish with a handful of strawberries and blueberries.
