Brazil put six past Uruguay without reply, including a stunning hat-trick from one of the stars of the tournament, Lucas.
Brazil booked their place in the London 2012 Olympics as well as retaining their second successive title at this level.
The game was a must win fixture for both sides and whoever came out on top would win the tournament.
Uruguay were shocked themselves to be in with a chance of winning it. A victory over Argentina saw them top the group before this match and they were confident of producing another upset.
But how wrong they were, Brazil walked all over them and fired six, yes six, goals past them in what turned out to be the tournaments most entertaining fixture.
The first goal came after 40 minutes when Sao Paolo wonderkid, Lucas, finished off a delightful team move.
Only a minute later did he double his tally and grab another for his side as he danced through the Uruguay defence to bring the title closer to Brazil.
Adrian Luna was sent off just after the break, effectively evaporating Uruguay’s chances of any comeback, and this was cemented when Matias Vecino, hero of the last round of games, skied a penalty.
The rest of the game was more a case of how many Uruguay could keep out the goal rather than going up the other end and scoring.
Constant pressure from Brazil resulted in a goal from Danilo, a brace from Neymar and one final goal for Lucas to finish his hat-trick.
Ney Franco’s side therefore triumphed in the tournament and will be made one of the favourites for the summers Under 20 World Cup.
Elsewhere, Argentina beat Colombia in their final group game 2-0 with goals from Facundo Ferreyra and Bruno Zuculini.
Ecuador defeated Chile to claim fourth place.
