Amid the meteoric growth of women's sports and exceedingly larger appetites from fans who are eager to enjoy all the action, ESPN has met the demand by stacking its lineup with the inaugural season of Athletes Unlimited Softball League.

As four teams made up of the world's best professional softball players take the diamond for a 24-game slate, the group of gals behind Sistersnacking teamed up with ESPN to create a little friendly food competition for its new fans.

Sara Shapiro, Carly Shapiro, Madison Vitale, and Julia Paperny -- the sisters behind Sistersnacking, popular online culinary content creators -- launched the Ultimate Snack-down with the Worldwide Leader in Sports to unveil the official snack of AUSL games.

"When Madison and I got to the stadium last week, the line was almost into the overflow parking lot of families and young girls waiting to attend the game. They were rocking the t-shirts of their favorite team and it just, it's really meaningful when we get to use our platform and work with such an amazing brand like ESPN and the AUSL to bring something so amazing to other women and young girls -- it feels really good," Sara Shapiro told "Good Morning America."

Each sister was tasked with creating a unique ice cream topping for the first-of-its-kind competition, with fans weighing in over the last few weeks to vote on their favorite via ESPNW's Instagram page.

On Thursday, Sistersnacking and ESPN announced exclusively with "Good Morning America" that the Bases Loaded Brownie Blast hit it out of the park, securing the win as the official AUSL snack.

Sara Shapiro, the oldest sister and CFO, created the winning sundae, which she said is made with "chocolate soft-serve with hot fudge drizzle, peanut butter swirl and a pretzel rod," plus "a big chunk of delicious brownie," all served with a chocolate straw.

"We all love all ice cream, so its hard to be mad about any one flavor coming out on top," said Carly Shapiro, who made the Strawberry Shortstop, a sundae inspired by strawberry shortcake. "We wanted to make sure they were all sundaes that people all across the country, because that's where the stadiums are, will love."

Vitale added, "Sara just came out on top with the chocolate. I feel like people gravitate towards that chocolate, fudgy brownie, and peanut butter. It was fun to have a tiny, friendly competition, but we were all really supportive of each flavor."
