Having lived in Amarillo for a few years on and off,  I usually try to keep up with anything cool going on there, especially if it is not happening in the Hub City. Amarillo has finally given up one of their coolest products to Lubbock, The Biti Pie. First of all, the Biti Pie can also be a Biti cake, but the franchise is called Biti Pie's and they are available at Lubbock Walgreen stores.
I have been fortunate enough to have been able to try the coconut cream Biti Pie and the german chocolate. The quality is as good as or better than you'd find at any bakery and the size is just right. For more on Biti Pies go HERE.
