Bock netted two minutes into the second period of extra time, firing home from close range after England failed to clear an inswinging corner. As the Three Lions pressed for an equaliser, Monique Kerschowski added a second with a minute to go.
The victory enabled Germany to retain the crown they won in Switzerland last year and give them their fifth continental championship overall.
"It feels great," said Germany coach Marie Meinert. "The second victory is no different to the first - they're all wonderful. It was a good game, England didn't really take the game to us, so it was important to come through in the end. In extra time they were still in good shape and it was hard to create the first goal."
"Obviously we're disappointed to lose in the manner we did, but that's the fine line between winning competitions and not," she said. "We were resilient, we were hard but I don't think we had enough quality to win the game - you have to have that extra bit of quality and Germany had that today.
"It's a new experience for all us and it shows what we can do. It's a foundation and now the bar has been raised and hopefully there are more finals to come."
Marley's side were undoubtedly the surprise package of the competition, topping group B, which included last year's finalists France, together with Span and Poland. Germany, meanwhile, enjoyed a 100 per cent record in the opening stage against Norway, Denmark and Iceland.
