Special equipment: four 6-ounce glass mason jars
Beat together the cream cheese and confectioners' sugar, in a large bowl, with an electric mixer on medium speed until well combined, about 2 minutes. Add in the sour cream, vanilla bean seeds and a pinch of salt and beat on medium-high speed until well combined, about 3 minutes.
Dissolve 1 teaspoon gelatin in 1 tablespoon hot water and beat into the cream cheese mixture.
Mix the crushed graham crackers, butter and granulated sugar in a small bowl until moist.
Spoon the graham cracker mixture into the bottom of four 6-ounce glass mason jars (don't press it down). Top with 1/4 cup of the cream cheese mixture, then 2 tablespoons of jam, spreading it all the way to the side of the jar, then another 1/4 cup cream cheese mixture. Refrigerate until set, about 2 hours. Garnish with fresh berries and mint.
