She could have just asked for an allowance.

A Texas teen was the mastermind behind a plot to carjack her dad — just to get some money out of him, Texas authorities said.

Deputies said two teen boys carjacked Susan Mize, 16, and her father Friday in their red Nissan — holding them at gunpoint and ordering them to drive home to fork over more cash, according to the Montgomery County Police Reporter.

Once at the house, the quick-thinking dad ran inside, locked the door and called 911, cops said.

The two men let Mize go and fled in the car before abandoning it and running into the woods.

One of them, a 16-year-old, was nabbed and the other is still at large.

Deputies also arrested Mize after learning she orchestrated the whole plot to steal from her dad.

She was taken to the Montgomery County Jail, where she is being held on $75,000 bond.

She faces aggravated robbery charges.
