At the 2015 European Championships in Montreux, Brânză switched her yellow mask for a tricolour one bearing Romanian colours. In the individual event she stopped short of the podium after a defeat in the quarter-finals to world No.1 Emese Szász. In the team event, Romania saw off Ukraine, then met Sweden, coached by Romanian Adrian Pop. Brânză entered the last relay on a draw and defeating Sweden's captain Emma Samuelsson to bring her team in the final. As in the 2013 edition they met Estonia, which they defeated this time on 45-30. Brânză claimed her sixth continental title, a record in women's épée. A few weeks later, she reached the final at the 2015 European Games in Baku after a sudden-death victory over Estonia's Erika Kirpu. She proceeded to defeat Russia's Yana Zvereva, winning Romania's first gold medal at the Games. In the team event Romania reached the final, where they met the same Estonian team as at the European Championships and produced a repeat performance to allow Brânză a double gold haul.
