Unlike most fruitcakes, this one is ready to eat as soon as it cools.
Heat oven to 350 degrees. Spread nuts on a baking pan. Bake until fragrant, about 10 minutes. Rub warm nuts in a clean kitchen towel to remove skins. Set aside.
Reduce oven heat to 300 degrees. Brush a 9-inch springform pan with soft butter, fit with circle of parchment, brush parchment with butter, and set aside.
Combine fruit, nuts, brandy, and chocolates in a medium bowl; set aside. Sift 1 cup flour and 1/2 teaspoon cinnamon in a bowl.
Combine honey and sugar in a saucepan. Stirring, bring sugar to a boil; reduce heat. Simmer for 2 minutes. Combine with dried-fruit mixture, stirring until combined. Fold in flour; mix to combine. Pour into prepared pan.
With wet hands or a small metal spatula, press the mixture to form a level layer. Combine the remaining 1/2 tablespoon flour, 1 teaspoon cinnamon, and cocoa. Sift over unbaked cake. Bake until set, about 30 minutes. Remove from oven, and cool. Gently brush off flour coating before serving.
