In a bowl take the condensed milk, add melted butter, fresh orange juice, orange marmalade, and blend well.

Next add the baking powder and baking soda, whisk and let it stand for 5 mins. Then add the flour and gently fold in.

Preheat the oven at 185 C. Line a baking loaf with parchment paper. Pour the batter into the tin and pat it down. The batter will be on the thicker side, so using a spatula scoop into the baking tin.

Bake for 30 mins at 185 C

Let it stand for 10 minutes before slicing.
