Heat oil in a large saucepan over medium heat. Add brown sugar and eggs; add to mixture while stirring occasionally. Bring mixture to a slow boil, stirring constantly, and let heat to about 140 degrees F (70 degrees C).
Add vinegar and whisk to combine. Reduce heat to low. Gradually add chocolate, stirring gently to get chocolate into mixture. Stir in cornflakes cereal, marshmallows, remaining margarine, and vanilla extract to mixture. Continue stirring, adding as little sugar as you can, stirring vigorously, until a mixture reaches desired consistency. Cool to room temperature, about 10 minutes.
