Break the brownies into pieces and divide the chunks between 4 serving glasses. Melt the After Eight mints gently, for about 20 seconds, in a bowl, in a microwave. Add 1 tablespoon boiling water and stir until smooth and thick. Take about a third of this warm chocolate fondant and spoon it over the brownies in the serving glasses.
Next, whip the cream until thickened, not too stiff, then fold in the rest of the chocolate mixture and the smaller amount of creme fraiche. Divide the chocolate mint cream between the four sundaes: you have layers of rich cake, dark chocolate mint fondant and a lighter chocolate cream. Finish with a dollop of creme fraiche and a grating of chocolate.
