Start by making the crust. In a food processor crush gluten free pretzel sticks. In a medium bowl combine the crushed pretzels, melted butter, and brown sugar and stir until the pretzels are coated.
Press the pretzel mixture into the bottom of a 9×13 pan.
To make the cheesecake combine the cream cheese, sugar, heavy whipping cream, vanilla, and salt in a large mixing bowl. Beat until smooth.
Spread the cheesecake mixture on top of the pretzel crust and smooth with a spatula.
Next top the cream cheese layer with strawberries and blueberries.
Drizzle melted chocolate on top of the berries.
Chill for a minimum of 4 hours before serving.
