Caroline Graham Hansen opened the scoring at the half-hour mark, and Ewa Pajor added two more first-half goals to effectively conclude the game before halftime.
Patri Guijarro scored the fourth goal in the 62nd minute, and Alexia Putellas sealed the win late on with a header from close range as Barcelona cruised to another Clásico victory.
The Supercopa is the first of four trophies available to Barça this season, as the Catalan club looks to duplicate last year’s quadruple, which included Liga F, the Copa de la Reina, and the Champions League.
Barcelona maintained their dominance over Real Madrid, winning the Spanish Supercopa Femenina final 5-0 for the fourth year in a row.
Madrid, meanwhile, was looking for their first trophy since acquiring CD Tacon in 2020, but they fell short against a vastly superior Barcelona team.
The two teams have now met 16 times in all competitions, with this being the first final, and Barça has won all of them.
Pere Romeu’s team dominated from the outset in Leganés on Sunday. Pajor’s early shot was ruled out by VAR, but Graham Hansen’s deflected effort fooled Madrid goalkeeper Misa RodrÃguez and led to a flurry of goals.
