Place a small saucepan over low heat and combine sugar and honey.
Mix until the sugar is dissolved, then set aside to cool.
In a large mixing bowl, combine flour, spices, almonds, hazelnuts, orange peel, and dried fruits.
Pour the sugar and honey mixture into the rest of the ingredients.
Mix to combine evenly. Note that this part might take a bit of effort, so feel free to use your hands directly if it's easier for you. The result will be chunks of dough.
Transfer the panforte dough into the prepared pan.
Use your hand to press the dough down and to even out the top surface of the cake.
Place the panforte in the middle of the oven for 20 to 25 minutes.
Remove the pan from the oven and set it aside for at least 20 minutes to cool.
Take your cake out of the pan and sprinkle with powdered sugar on top.
Cut panforte into wedges and serve, with more powdered sugar, if preferred.
