1/2 cup of orange juice
1/2 stick of butter
Whisk the butter, condensed milk and orange juice together and then add the cake mix and whisk until smooth. Set aside. In a separate bowl whisk the eggs and gently fold into the previous mixture. This will make your cake feel lighter (although this is not a light cake - it will be a bit dense but super moist and yummy). Then prepare the pan dish of your preference (butter and flour) - I used a bundt cake pan but you can also use a pound cake pan. Pour the mix and bake per the box instructions. In my case, it was 35 mins at 375 deg F.
