After taking a break from baking, I decided to whip up some chocolate cupcakes with marshmallow frosting the night before my FIG lecture.

This was also the very day that I invited Dr. Iverson to come to my FIG. He’s a popular organic chemistry professor at the University of Texas and the coauthor of the textbook Organic Chemistry. Gesturing toward the cupcakes he asked, “What’s the occasion?” Amanda told him that she brings food every time. Satisfied with the answer he plopped down and helped himself to one. He was even more pleasantly surprised that they were cream filled.

Over the past couple of weeks my students have been asking if Iverson really discovered the cure for Anthrax. 
Indeed, the rumors are true. 
More interesting the idea struck him when he was watching Balto the Disney movie with his daughter.

First time I had marshmallow frosting and I enjoyed it :). Not to mention it’s super easy. However, I’m not impressed with the chocolate cupcakes. Stay tune for my favorite chocolate cupcake recipe!
