Elizabeth Olsen has been working up a sweat around Los Angeles to stay in fighting form for her forthcoming superhero flick Avengers: Infinity War.

And the actress rewarded her discipline on Monday in Studio City, California, when she popped into McConnell’s Scoop Shops for a frozen treat.

The younger sister of actresses Mary-Kate and Ashley Olsen sampled four different flavors before selecting one to fill a pint-size order, along with a large cookie that she carried out in her hand.

The blonde was casual for the solo outing and kept her look simple with jeans, a brown sweater and a black jacket. Her ombre tresses were styled loose and rested around her shoulders, and she opted to go make-up free.

Last week she turned 28 years old and didn’t shy away from cake when she celebrated among friends.

And there are more big things ahead for the movie star to celebrate, as her big screen career is busier than ever.

The movie star is currently reprising her role as Scarlet Witch in the third installment of the Avengers, which will hit theaters next year.

Last month she wrapped promoting her two forthcoming pictures at the Sundance Film Festival, Wind River and Ingrid Goes West.

Just premiered: In Ingrid Goes West, Elizabeth stars as Taylor, a social media celebrity whose online presence enraptures Ingrid, an unhinged woman played by Aubrey Plaza

Haunting: Wind River stars Jeremy Renner as Cory Lambert, a US Fish & Wildlife agent, and Elizabeth as Jane Banner, a rookie FBI agent

In the drama Wind River, she plays opposite her Avengers co-star Jeremy Renner as a rookie FBI agent who teams up with the US Fish & Wildlife agent in the investigation of a dead and raped teenage girl who was discovered in Wyoming’s Wind River Indian Reservation.

In the dark comedy Ingrid Goes West, Elizabeth stars as Taylor, a social media influencer whose e-fame enraptures an unhinged woman played by Aubrey Plaza.
