Preheat your oven to 350°F (175°C). Grease and flour a cake pan.
In a mixing bowl, combine the flour, baking powder, cinnamon, nutmeg, and salt.
In another bowl, beat the softened butter and brown sugar until creamy.
Add eggs one at a time, mixing well after each addition.
Stir in the applesauce and orange juice until combined.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Fold in the mixed dried fruits and nuts gently.
Pour the batter into the prepared cake pan and spread evenly.
Bake for 75 minutes or until a toothpick inserted in the center comes out clean.
Let the cake cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
