This recipe has a couple of items that need advance preparation. You'll want to begin making this dessert early in the day, or one day before you serve.
Bake and Slice the Cake
To begin, bake an angel food cake (either homemade or package variety) according to baking instructions. Allow to cool before cutting into pieces.
(You may opt to buy an angel food cake that is already made. If so, the loaf type would work really well for this recipe. One should be enough.)
Slice the cake into bite-size cubes. I found using a serrated bread knife works well for doing this task.
Prepare the Gelatin and Strawberries
Prepare strawberry and blueberry gelatin according to package directions. Cover each and refrigerate to set.
Rinse and drain the strawberries and blueberries. If desired, you may cut the strawberries in half or in chunks.
(If desired, you may add fresh cut strawberries to the strawberry gelatin before it sets, and/or fresh blueberries to the blueberry gelatin.)
Assemble the Dessert
Gather your ingredients so that you have everything close at hand on the counter or table.
In a large mixing bowl, using a large wire whisk, whip together one container of whipped topping and Fiori di Sicilia flavoring. (This step is optional.)
Begin assembling the dessert by making the Red layer. Spoon the set strawberry gelatin with strawberries to the bottom of the dish. If you didn't add strawberries to the gelatin, spoon them over the gelatin now in a single layer.
Next create the White layer, by spooning the whipped topping mixture over the strawberries. Sprinkle miniature marshmallows over the whipped cream. Generously add pieces of cake over this, and top with more whipped topping, pressing down to pack the cream.
The cake and cream is the "filler" for this dessert, and will take up the majority of the space. Use as much as you need to fill the dish, leaving just enough at the top for the blueberry gelatin.
Next, spoon the blue gelatin over the whipped cream mixture. Add half of the fresh blueberries over the gelatin.
Finish by covering the blue layer with the remaining whipped topping, carefully spreading it to the edges. If desired, use sliced strawberries and blueberries to make a star design.
Serve immediately or cover and refrigerate until ready to serve. Serves 8.
Notes
To make a second version of this dessert, simply follow the ingredients above, but skip the gelatin and marshmallows. Depending on the size of your serving dish, you may need to double the amounts of angel food cake, whipped topping and fruit. Assemble by layering the cake, whipped topping mixture, and fruit until you reach the top.
Both of these desserts are best served the day you make them, but may be refrigerated for up to 4 days.
