Preheat oven to 300 degrees F. and adjust oven rack to center position.
Prepare Bread Crumb Lining and line the baking pan; set aside.
In a small bowl, combine 1/2 cup cake flour, 1 teaspoon cinnamon, coriander, cloves, and nutmeg; set aside.
In another small bowl, combine the remaining 2 tablespoons of cake flour and 1/2 teaspoon cinnamon; set mixture aside and save for the top.
In a medium saucepan over low heat, combine honey and sugar. Cook, stirring occasionally to prevent scorching, until mixture comes to a full boil; remove from heat. Stir in candied fruit and almonds or hazelnuts. Sift in flour mixture; stir until well blended. Pour batter into prepared pan. Smooth top with the slightly wet palm of your hand. Sift reserved cinnamon-flour mixture over the top.
Place cake in center of middle oven rack. Bake 30 minute or until panforte just starts to simmer around edge of pan. Remove from oven; cool completely on a wire rack.
Loosen from pan by running a small knife around perimeter (if using a Springform Pan, remove sides of springform pan). Invert onto a wire rack, letting excess cinnamon flour fall away. Use knife to peel away parchment or rice paper. Invert panforte again and transfer onto a wire rack. Dust top with powdered sugar.
When cool, it can be wrapped in several layers of plastic wrap and a layer of aluminum foil and stored in an airtight container for several weeks, or frozen for up to six months.
Serve at room temperature. Before serving, dust lightly with additional powered sugar. Cut into small wedges to serve.
Makes 16 servings.
Brush an 8-inch cake pan or an 8-inch Springform Pan with butter. Cut a dish of parchment paper, or rice paper* to fit pan bottom. Brush paper with butter and fit into pan bottom. If using Asian-style rice paper, wet the paper to make it easier to cut, then trim it to the correct size with scissors.
In a small bowl, combine cake flour, bread crumbs, and almonds or hazelnuts; evenly scatter over sides and bottom. Pat gently into place.
* To toast nuts, preheat oven to 350 F. Place nuts in a single layer in an ungreased shallow pan or rimmed baking sheet. Bake 5 to 10 minutes, stirring once or twice during toasting to aid in even browning, or until they are golden brown. Remove from oven and remove from pan; let cool. If using hazelnuts, remove from pan; place hazelnuts in a clean terry-cloth towel and wrap it closed. Let the nuts steam for 4 to 5 minutes then rub vigorously for 1 to 3 minutes on a hard surface to remove skins; discard skins.
