I have 10 years experience in the pastry field and have worked at some really amazing restaurants/hotels/bakeries. Having an open mind and being driven to constantly be learning and trying new things will get you far in any career you choose. I would echo the answer that if you are looking to open your own business in the future, pursuing a degree with business would be very helpful.
I graduated from the French Pastry School in Chicago with a L'Art de la Pâtisserie certificate (Pastry and Baking). The program is through Robert Morris University. I took the program in 2007 and at that time it was just a certificate. Now, "students are formally enrolled in RMU's Bachelor of Professional Studies - Advanced Culinary and Hospitality Management degree when they attend the FPS full-time courses. They have the option of only completing the FPS courses or they can continue with additional coursework at RMU in pursuit of a BPS degree."
I have been a pastry chef in the industry for 10 years and I have found that you don't need a four year degree to be a successful pastry chef. I have worked as a Chocolatier at the Aria Resort & Casino in Las Vegas and owned my own gelato business with a certificate. However, there are four year programs if you would like to earn a degree!
That is a tough question! There are culinary art schools, separate from colleges, but I don't know if they let you specialize in baking. You will want to check them out. As for traditional colleges, they too offer food science and other such courses. I would encourage you to find the best pastry program that you can, and then to minor in business, if you are thinking of starting your own business.

Our diploma programs have a range of concentrations from cuisine to culinary arts to baking and pastry making. If you are a beginner, completing a diploma program will give you the foundation you need to start a culinary career. For students who wish to learn more, we offer a longer Associate Degree Program in Culinary Arts. Learn everything from classical to modern techniques as well as leadership and management skills.
This is from the Culinary Institute of America, in San Antonio:
Here, we offer our innovative associate degree programs in either culinary arts or baking and pastry arts, based on the same curriculum that has helped so many future food leaders at our main campus in Hyde Park, NY.
Best of luck!
