In a mixing bowl sift together the flour and baking powder. Set aside.
Put a small pot over a very low flame (I used the lowest flame possible) and combine the cocoa, wine, sugar and butter. Stir with a wooden spoon until the butter has melted and the mixture is smooth, about 5 minutes.
Remove from heat and whisk in the eggs one at a time, making sure each egg has been fully absorbed before adding another. Once the eggs are fully incorporated whisk in the flour and baking powder until fully absorbed.
Fold in the chocolate chips and pour into the prepared pan.
Bake for 40-45 minutes, or until the center is springy.
In the meantime make the glaze.
To make the glaze:
Put a pot over a very low flame and combine the cocoa, wine, sugar and butter. Stir with a wooden spoon until the butter has melted and the mixture is smooth. Remove from heat. The mixture will thicken as it cools.
Once the cake is baked dock the surface with a formal. Optionally you May brush the cake with extra Primitivo wine.
Place the cake over a wire rack and pour the glaze over the top. Serve with a lovely glass of Primitivo wine!
