Beat the butter and sugar until frothy. Then add the egg and pumpkin puree. Stir in the vanilla pulp, salt, nuts, chocolate and Grand Marnier (I`ve already replaced this with brandy). Finally add the flour mixed with baking powder.
Using a tablespoon, place small heaps on a baking sheet lined with baking paper and bake for about 15 minutes at 190 ° C until golden.
