Happy B-day, Nam.
Are you allergic to gluten? Never heard of a cake allergy and I was getting ready to send a cheerleader to you to jump out of a cake...
I don't know. Ever since I was 7-8 years old cake, twinkies, ho-ho's and anything similar have given me massive headaches. I like cake, I just don't like the massive headaches that come with them. I can eat muffins, though and cupcakes, and of course pie.
There is one cake I can eat that just gives me a minor headache rather than a massive one and that's carrot cake.
