Okay, so you see this beautiful, festive flag cake?
And you think it must have been a whole project. A labor of love. A serious baking endeavor.
It’s not. It’s actually laughably simple. (The biggest effort is arranging the berries.)
How to Arrange the Berry Flag Pattern
The whipped topping is your flag canvas. Get those berries ready!
CREATE three horizontal stripes: use RASPBERRIES for the top and bottom stripes, and BLACKBERRIES for the middle stripe. Make sure the lines are straight and full.
For a classic look, think red, white, and blue but with berries: RASPBERRY (red), whipped topping (white), and BLACKBERRY (blue). Fancy, right?
Keep the cake FROZEN until you’re ready to slice. Serve IMMEDIATELY so the pattern stays sharp and the ice cream doesn’t run. Done and delicious!
Make-Ahead & Storage Tips
- Assemble up to 5 days ahead, wrapped TIGHT in plastic wrap then foil. Keeps freezer burn away (the enemy!).
- Save the whipped topping and berry design for serving day… they look way fresher that way.
- Slice with a sharp knife dipped in HOT water, wiped dry between cuts. Clean slices, no smashing.
- Leftovers in an airtight container, freezer, up to 2 weeks. (If any even survive!?!)
Ice cream cake is basically a MAKE-AHEAD DREAM. Do the work now, impress later….

Ingredients
For the crust:
- 6 graham crackers (finely crushed into crumbs)
- 1/4 cup almonds (finely chopped for a nutty texture)
- 2 tbsp brown sugar
- 4 tbsp butter (melted Kerrygold unsalted butter)
- 1/8 tsp salt (to enhance flavor)
For the base:
- 3 pints vanilla ice cream (softened for 15-20 minutes to spread easily)
- 1/2 cup blackberry jam (I use Smucker’s for the best color)
- 3 graham crackers
- 1/2 tsp lemon zest (finely grated, to mix into the jam)
For the topping:
- 3 cups whipped topping
- 12 blackberries (standard flag proportions)
- 1 pint raspberries (rinsed and patted completely dry)
Step 1: Bake the Nutty Graham Crust
- 6 graham crackers, finely crushed
- 1/4 cup almonds, finely chopped
- 2 tbsp brown sugar
- 4 tbsp melted butter
- 1/8 tsp salt
Preheat your oven to 350°F.
Pulse the 6 crushed graham crackers, chopped almonds, brown sugar, salt, and melted butter together in a food processor until the mixture resembles wet sand with some texture remaining—you want it to hold together but not become a paste.
Press this mixture firmly and evenly into the bottom of a 9×13 inch baking dish, using the bottom of a measuring cup to create an even layer.
Bake for 10 minutes until lightly golden, then remove from the oven and let cool completely to room temperature, about 10-15 minutes.
Step 2: Assemble the Creamy Jam Layers
- cooled graham cracker crust from Step 1
- 3 pints vanilla ice cream, softened
- 1/2 cup blackberry jam
- 1/2 tsp lemon zest
- 3 graham crackers
Spread the softened vanilla ice cream (about 1.5 pints) evenly over the cooled crust in an even layer—I find an offset spatula dipped in warm water works beautifully for this.
Mix the lemon zest into the blackberry jam to brighten the flavor slightly, then spread the jam mixture over the ice cream layer.
Crumble the remaining 3 graham crackers by hand and sprinkle them over the jam layer, then top everything with the remaining softened ice cream (about 1.5 pints), spreading it smooth.
Step 3: Chill Solid and Spread Topping
- frozen ice cream cake from Step 2
- 3 cups whipped topping
Freeze the ice cream cake for at least 2 hours until the ice cream is completely firm.
Once frozen solid, spread the whipped topping evenly across the top of the cake using an offset spatula or the back of a spoon, creating an even layer that will hold the berries.
Step 4: Decorate with Fresh Patriotic Fruit
- prepared cake from Step 3
- 12 blackberries
- 1 pint raspberries, rinsed and patted dry
Arrange the raspberries and blackberries on top of the whipped topping in a flag pattern: create three horizontal stripes using raspberries for two stripes and blackberries for one stripe, alternating colors.
For a classic American flag look, use two raspberry stripes on the bottom, one blackberry stripe in the middle, and finish with a raspberry stripe on top (or adjust to your preferred color pattern).
Keep the cake in the freezer until ready to serve, then slice and serve immediately so the cake doesn’t melt too quickly.
