"Pangiallo is a traditional Italian Christmas cake, originally from Rome. Dried fruits and nuts are mixed with oil, wine, and flour to create a humble yet tasty treat that is vegan to boot! Wrap in cellophane or Christmas paper and give as gifts to friends and family."
Preheat oven to 350 degrees F (175 degrees C). Line a baking sheet with parchment paper.
Combine prunes, raisins, almonds, walnuts, hazelnuts, sugar, orange marmalade, candied orange peel, and cinnamon in a large bowl and stir to combine with a wooden spoon. Pour in wine and olive oil. Add flour and mix everything into a sticky dough, adding more flour if mixture does not stick together.
Shape mixture into 8 similar sized logs with wet hands and place onto prepared baking sheet.
Bake in the preheated oven until golden, about 30 minutes.
