This has been transmitted by al-Hakam through a different chain of narrators. This version has:

O Allah, bless Muhammad and Muhammad’s family as didst bless Abraham. You are indeed praiseworthy and glorious. O Allah grant favours of Muhammad and Muhammad’s family as You didst grant favour to Abraham’s family. You are indeed praiseworthy and glorious. Abu Dawud said: This tradition has been narrated by al-Zubair b. ‘Adi as narrated by Mis’ar , except that his version goes: As You didst bless Abraham’s family. You are indeed praiseworthy and glorious. And grant favours to Muhammad. He then narrated the tradition in full.

حَدَّثَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، حَدَّثَنَا ابْنُ بِشْرٍ، عَنْ مِسْعَرٍ، عَنِ الْحَكَمِ، بِإِسْنَادِهِ بِهَذَا قَالَ ‏"‏ اللَّهُمَّ صَلِّ عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّدٍ كَمَا صَلَّيْتَ عَلَى إِبْرَاهِيمَ إِنَّكَ حَمِيدٌ مَجِيدٌ اللَّهُمَّ بَارِكْ عَلَى مُحَمَّدٍ وَعَلَى آلِ مُحَمَّدٍ كَمَا بَارَكْتَ عَلَى آلِ إِبْرَاهِيمَ إِنَّكَ حَمِيدٌ مَجِيدٌ ‏"‏ ‏.‏ قَالَ أَبُو دَاوُدَ رَوَاهُ الزُّبَيْرُ بْنُ عَدِيٍّ عَنِ ابْنِ أَبِي لَيْلَى كَمَا رَوَاهُ مِسْعَرٌ إِلاَّ أَنَّهُ قَالَ ‏"‏ كَمَا صَلَّيْتَ عَلَى آلِ إِبْرَاهِيمَ إِنَّكَ حَمِيدٌ مَجِيدٌ وَبَارِكْ عَلَى مُحَمَّدٍ ‏"‏ ‏.‏ وَسَاقَ مِثْلَهُ ‏.‏
