Larsen spent the first season of her professional career with BK Skjold before moving on to Brøndby IF for the next three seasons. Larsen's first stint playing in the United States came immediately after the conclusion of the 2011–12 Danish Women's League season, she flew to the United States the day after her last match for Brøndby IF.[2] She played in seven matches for the newly established Colorado Rapids in the 2012 W-League season, the team finishing fourth in the Western Division.[3]
Following the end of the W-League season Larsen would return to Denmark, this time joining Fortuna Hjørring for two seasons. She would then return to the United States for the 2015 National Women's Soccer League season, where she made three appearances for the Western New York Flash.[4] Larsen would move from the Flash to AGSM Verona in Italy, though her time there was short as she left the club due to unpaid salary after she had surgery on her knee.[5][6]
She would return to Denmark and her former club Hjørring for a season and a half, where she would win the domestic league and cup double. Larsen would once again go abroad in 2017, this time to Vålerenga for her first season in Norway.[7] After her time in Norway, Larsen took a break from football due to her pregnancy and birth of her first child. She returned to the pitch in the 2019–20 season with FC Nordsjælland who she played with for two seasons.[8] Larsen would return to Hjørring for a third and ultimately final time ahead of the 2021–22 season.[9]
After the conclusion of the 2021–22 Danish season, Larsen moved with her daughter to England where her husband, Brian Sørensen, was managing Everton.[10] In her final match in Denmark, her 136th with Fortuna Hjørring across three stints, she scored the winning goal against Sundby BK.[11] After moving to England, Larsen would go on to join Blackburn Rovers just over halfway through the 2022–23 Women's Championship on 28 February 2023, her first time playing for an English club.[12] After encountering injuries in her partial season with Blackburn and only making five total appearances, Larsen retired on 22 May 2023, bringing an end to her 15 year professional career.[13][14]
