Puzzle #1 is impossible. Theoretically you could play dxe6 en passant, but black’s last move wasn’t provided so we can’t assume that’s possible.

bxe5+ dxe5 isn’t mate.

I think capturing en passant was the way to mate your opponent immediately in that position

Dxe6# enpassant

The Answer is dxe6# en passant checkmate. Some people didn't notice this because the post didn't say anything about the first move. So, in conclusion the only POSSIBLE mate in 1 (without the first move being shown or displayed) is dxe6#.
