Preheat Oven: Preheat the oven to 170°C (340°F). Grease and line a cake tin with parchment paper.
Mix Wet Ingredients: In a large bowl, whisk together curd, milk, butter, oil, vanilla extract, and sugar until smooth and well combined.
Sift Dry Ingredients: In another bowl, sift the all-purpose flour, cocoa powder, baking powder, baking soda, cinnamon, clove, and nutmeg powder.
Combine Wet and Dry: Gradually fold the dry ingredients into the wet mixture until just combined.
Add Zest, Nuts, and Fruits: Gently fold in the orange zest, chopped nuts, and mixed dried fruits.
Bake: Pour the batter into the prepared cake tin. Bake for 35-40 minutes or until a toothpick inserted in the center comes out clean.
Cool and Serve: Let the cake cool in the tin for 20 minutes, then transfer to a wire rack to cool completely before serving.
