    Stir vanilla into the frosting until fully combined.

    Spoon half the frosting over the cake layer in each jar, pressing gently to fill gaps.

    Top with crushed cookies, then remaining frosting, then more cookies for the final layer.

    Chill for 5 minutes, then serve cold or at room temperature.
