Preheat oven to 375 degrees. Whisk together the eggs and sugar until frothy. Add vanilla specks, flour, and salt. Mix until incorporated. Fold in the milk and 1/2 the creme fraiche.
Spray a 10-inch teflon pan with vegetable spray. Pour 1/3 of the batter into the pan. Bake in the oven for 3 minutes, just until the batter sets. Remove pan from oven and spread the mixed berries on as the next layer. Pour remaining batter over the berries. Return the pan to the oven and continue baking for 12 to 16 minutes, or until the edges start to brown and the middle rises. Take out and let cool for 20 minutes.
Mix the remaining 1/3 cup of creme fraiche with the confectioners' sugar. Cut the clafouti into 4 to 6 wedges, dust with the extra confectioners' sugar and serve with the remaining berries and sweetened creme fraiche.
