The world champion-elect had been able to successfully convert pole position into a win to double up on his sprint race triumph from Saturday, having beaten Norris once again in an initially close-fought contest that eventually led to the two drivers diverging.
Verstappen was barely troubled beyond the opening 10 laps and, despite a Norris fightback towards the end as the McLaren driver had opted for a strategy offset in the final stint, had enough in hand to cross the line with a 8.2s advantage.
Although Norris was only sixth on the grid, the McLaren driver moved into contention with two key events either side of the start: first, Charles Leclerc had suffered a hydraulic issue on the formation lap and hit the wall at Ferradura, which killed his race before it had even begun.
This opened up a grid space on the front row, which Norris moved into as the slow-starting Fernando Alonso ahead offered a prime opportunity to break down the inside into the first corner and collect second, as Lewis Hamilton rounded both Aston Martins on the outside to slot in behind.
The race was red flagged thanks to a crash between Alex Albon and Kevin Magnussen at the first corner, and Norris crucially held off Hamilton at the restart to ensure he retained second place.
Norris began to put Verstappen under scrutiny over the next three tours and harried him on the eighth lap, when he attempted to prise open a gap on the outside of the first corner. He followed that up with a look at Turn 4, but this was countered by Verstappen and the McLaren driver subsequently had to back off having taken a hefty chunk of life out of his tyres.
The gap between the leaders soon opened to over two seconds as Norris struggled to get back on level terms, with the arrears continuing to increase as Verstappen had the pace advantage.
