Prep the Nuts and Fruits:
Toast almonds and hazelnuts in a 350°F oven for 8–10 minutes. Chop all dried fruits, candied orange peel, and nuts.
Make the Syrup:
In a medium saucepan, combine honey, granulated sugar, and brown sugar. Heat gently until sugar dissolves. Add cinnamon, nutmeg, cloves, and black pepper. Stir until fragrant.
Combine Dry Ingredients:
In a large bowl, sift together flour and cocoa powder. Mix in toasted nuts and chopped fruits.
Add Syrup:
Pour warm syrup over dry ingredients. Stir well until it forms a thick, sticky dough.
Shape the Cake:
Line an 8-inch round cake pan with parchment paper. Press the dough evenly into the pan. Smooth the top.
Bake:
Bake in a preheated oven at 325°F for 25–30 minutes. The cake should be firm but slightly soft inside.
Cool and Dust:
Let the cake cool completely in the pan. Remove and dust generously with powdered sugar before serving.
