The young striker hit four goals in their 5-0 rout of Ipswich Town.
Hammers U21 coach Nick Haycock told West Ham TV: "We were just laughing about it in the tunnel because we thought he could have had eight goals today and he probably knows that.
"Elliot's a finisher and he's the type of forward who could miss two easy chances and still end up with a goal and that's the sign of a good striker.
"The other week against Manchester City he worked hard but didn't have any chances and sometimes that happens but when he gets chances he takes them."
