Begin by dicing 2 cups of fresh peaches and placing them in a medium bowl. Drizzle with 1 tablespoon of lemon juice to enhance their flavor and prevent browning. Toss gently to coat each piece.

In a large mixing bowl, pour in 1 cup of heavy cream. Using an electric mixer, whip the cream on medium-high speed for about 3 to 5 minutes, or until soft peaks form.

In another bowl, combine 8 oz of softened cream cheese, 1/2 cup of powdered sugar, and 1 teaspoon of vanilla extract. Using a hand mixer, blend these ingredients together until the mixture is smooth and creamy.

Carefully fold the whipped cream into the cream cheese mixture using a spatula. Begin by adding a third of the whipped cream to lighten the mixture, then gently incorporate the rest.

Once your whipped cream is fully integrated, fold in the marinated peach pieces until evenly distributed.

In a small bowl, mix together 1 cup of graham cracker crumbs and 1/4 cup of melted butter. Stir until crumbs are evenly coated.

In your chosen serving dish, add a layer of the graham cracker mixture. You can either layer it at the bottom or fold it into the fluff.

Cover the dish with plastic wrap or a lid and place it in the refrigerator. Allow the Peach Cheesecake Fluff to chill for at least 2 hours.
