In a large mixing bowl, using a hand mixer or a stand mixer, combine heavy cream, powdered sugar, and vanilla extract. Start mixing on low speed to avoid splatters, then gradually increase the speed to high. Beat this mixture until stiff peaks form, which usually takes about 3 to 5 minutes. It’s important to keep an eye on it; you want it to be fluffy and light, not over-beaten and grainy. Once ready, set aside about half a cup of this whipped cream for later use.
In a separate medium mixing bowl, beat cream cheese until it’s smooth and creamy. This takes about 2 to 3 minutes. Make sure there are no lumps, as you want a silky texture. Once it’s smooth, gently fold the remaining whipped cream into the cream cheese mixture. This folding technique ensures that you keep the airiness of the whipped cream, making your cake light and fluffy.
Now, it’s time to assemble your cake. Take a 9X9-inch baking dish and spread a thin layer of the cream cheese and whipped cream mixture on the bottom. This layer acts as a glue, helping the graham crackers stay in place.
Next, carefully place a layer of graham crackers over the cream cheese mixture. Make sure to cover the entire surface. This layer will provide a nice crunch and will soak up some of the creaminess from above.
Spread half of the cream cheese and whipped cream mixture over the graham crackers. Use a spatula to smooth it out evenly.
Now, add one cup of your fresh mixed berries onto this layer, distributing them evenly. This adds a burst of flavor and color that really elevates the cake.
Repeat the layering process: add another layer of graham crackers, followed by the remaining cream cheese mixture, and top with another cup of berries. Each layer enhances the cake’s overall texture and flavor.
The final touch is to add one last layer of graham crackers. Once done, take the reserved whipped cream and spread it over the top layer of graham crackers. This creates a beautiful white surface that will be lovely once garnished.
For the finishing touch, sprinkle the final cup of berries over the whipped cream layer. If you want to be festive, you can arrange them in a flag pattern for holidays!
Cover the baking dish with plastic wrap and place it in the refrigerator for at least 4 hours, or overnight. This allows the graham crackers to soften and absorb the flavors, creating a magical transformation!
