In a large bowl, combine the berries and 1/3 cup of the sugar. Let sit for at least 15 minutes (and up to 4 hours, refrigerated).
In a medium bowl, whip the cream and the remaining 2 tablespoons of sugar until soft peaks form.
Split the biscuits in half. Top the bottom halves with the berries and whipped cream and sandwich with the remaining biscuit halves.
