England began confidently and captain Jordan Henderson headed a free header wide before they took the lead in the 10th minute.
It was a first goal at Under-21 level for Blackpool's sought-after forward Thomas Ince, who poked home Adam Smith's cross from the right.
Jonjo Shelvey then somehow missed the target with a free header from six yards out but made up for it by netting the second.
The Liverpool man was presented with an easy tap-in after Ince's shot had hit a defender and looped into his path.

It was three before half-time when Ince scored his second. He was fouled in the area and followed up Josh McEachran's saved penalty to give the Three Lions a comfortable lead at the interval.
England manager Stuart Pearce made four substitutions at half-time and one of the entrants, Connor Wickham, squared for Ince to complete his hat-trick on the hour mark but he was denied by August Stromberg's save.
Sweden never really threatened the hosts' goal. Andreas Blomqvist came closest to scoring a consolation, dipping a shot wide of Declan Rudd's goal.
Wickham would be the man to score the fourth, powerfully heading home Henri Lansbury's cross 13 minutes from time to seal the win.
