Cut gluten-free angel food cake into ½ inch cubes.
Wash and hull the strawberries, then cut into slices lengthwise.
Wash and dry the raspberries and blueberries.
In a large mixing bowl, add room temperature cream cheese, sifted powdered sugar, and vanilla extract. Use hand-held beaters or a stand mixer with the paddle attachment to whip the cream cheese on low until combined. Then whip the mixture on high until it is fluffy, about 2-3 minutes.
Scoop half of the whipped cream into the cream cheese mixture. Fold it in with a spatula. Gently fold in the remaining whipped cream until the mixture is smooth, creamy, and fluffy.
To assemble the trifle, spread a thin layer of the cream cheese mixture on the bottom of a 3 quart trifle bowl.
Arrange a layer of the angel food cake cubes, then add 1/3 of the blueberries, 1/3 of the raspberries, and 1/3 of the strawberry slices. Top with ½ of the cream cheese mixture.
Repeat with another layer of angel food cake cubes and half of the remaining berries.
Top with the last of the cream cheese mixture. Garnish the trifle with the remaining angel food cake cubes and berries.
Cover the trifle and place it in the refrigerator for 2-4 hours before serving. Trifles are best served the day they are assembled.
Store leftovers in an airtight container in the refrigerator.
