Melt the chocolate on the lowest temperature in a small saucepan (4-5 minutes). Pour the melted chocolate into a food processor or blender. Melt the butter in the same saucepan and pot in with the chocolate.Add the eggs, cream, pumpkin, vanilla and xylitol to the melted chocolate mixture and blend until combined.
Quickly mix the flours, salt, cocoa and baking powder in a separate mixing bowl. Add the chocolate mixture to the flour mix. Whisk and pour into a buttered oven dish or brownie tin (25 x 25 cm).
Bake for 14 - 15 minutes until it is firm on the sides and somewhat gooey in the middle. Allow to cool.
