Prepare the Wet Mixture:
Preheat your oven to 325°F (160°C) and grease a deep 9-inch round cake tin. In a medium saucepan, combine the water, golden syrup, molasses, and butter. Heat over low flame until the butter melts and the mixture is smooth. Let it cool slightly.
Add the Sweet Zest:
Stir in the grated orange zest and sugar into the syrup mixture. Whisk until the sugar dissolves and the zest releases its aroma.
Mix the Dry Ingredients:
In a large bowl, sift together the flour, baking soda, cinnamon, and ginger. Make a well in the center.
Combine Wet and Dry:
Gradually pour the wet mixture into the dry ingredients, whisking constantly to prevent lumps. Once smooth, beat in the eggs gently.
Bake:
Pour the batter into the prepared tin and bake for 55-60 minutes or until a skewer inserted in the middle comes out clean. Cool in the tin for 15 minutes, then transfer to a wire rack to cool completely.
Prepare the Icing:
Sift the confectioners’ sugar into a bowl. Gradually stir in the orange juice until smooth and thick but pourable.
Finish with a Drizzle:
Pour the icing over the cooled cake, letting it drip down the sides. Allow the icing to set before slicing.
