Walnut & Cinnamon Cake

For the cake:

1. In a bowl, beat the brown sugar with the honey and the butter until it turns into a cream.
2. Separate the yolks from the egg whites and add the egg yolks to the previous cream and beat until a fluffy cream is obtained.
3. Add the ground walnut, the flour, the baking powder, the cinnamon and the fennel. Mix well but don't beat.
4. Beat the egg whites and incorporate them gently into the previous preparation. Pour the dough into a pre-greased, rounded paper-lined form and bake for approximately 30 minutes at 180°C or 350°F or until it's baked (do the toothpick test).
5. Let it cool, unmold and place it on a serving plate.

For the icing:

1. In a saucepan, heat all the ingredients, stirring constantly with a whisk until it boils and the butter melts.
2. Remove it from the heat and allow it to cool completely before pouring it over the cake.
