Help! Aliens have taken my mother!

Something is very wrong with my mother!  Last night, she was prowling the house, complaining that we had no ice cream, cookies, or other baked goodies. 
"Don't we have any junk food?" she inquired as she opened and closed cabinets.  "Hey, we have ice cream cones.  We can have those with marshmallows and peanut butter in them."
The rest of us stared at her in disbelief.  Did our mother just suggest that we eat marshmallows?  As she assured us that she was not kidding, we were left with one conclusion: she must be under the influence of aliens from outer space!  (Yup, we were watching Star Trek.)
She proceeded to melt chocolate and serve us all ice cream cones stuffed with almond butter, marshmallows, melted chocolate, and chocolate chips.  Our confusion only deepened when Josh asked if he could have a second cone. 
"Why not?" Mommy replied.  "Have whatever you want."
What is wrong with her!?! and what do we do about it?
