In a mixing bowl, whip the chilled heavy cream on medium-high speed for about 3 minutes until soft peaks form, and it holds a gentle curl when you lift the beaters.
In another bowl, beat the softened cream cheese, vanilla extract, and sugar (if using) until smooth and slightly fluffy, about 2 minutes. This creates a creamy, tangy base.
Gently fold the whipped cream into the cream cheese mixture using a spatula, adding a little at a time. Carefully combine until the mixture is light, airy, and uniform.
Chop the candy corn into small, bite-sized pieces, ensuring they’re not mushy but still show in each layer.
Start layering your parfaits by spooning a layer of crushed graham cracker crumbs into the bottom of each glass, followed by a generous layer of the creamy mixture.
Sprinkle some chopped candy corn over the cream layer, then repeat with another layer of graham crackers, cream, and candy corn, finishing with a swirl of cream on top.
Gently press down on the layers and refrigerate the parfaits for at least 1 hour to allow the flavors to meld and the layers to set beautifully.
Before serving, add a few extra pieces of candy corn on top for a colorful, festive finish. Serve chilled and enjoy the creamy, crunchy layers that evoke fall’s nostalgic flavors.
