You describe yer site as a cupcake site, but it is also about cakes; so it is more accurately a baking or cake site. As to the site:
The "cake-supplies.org" logo seems a be a bit lackluster. The menu widths are probably fixed; but the highlight on the menu title does not match the width of the menu itself - although it seems as if it should. When you click on a menu title, is it doing what you intend? It doesn't seem so. You might want to disable those links. I don't see where it says where you actually are - a reassuring thing when you actually want to do business with someone. Your name(s) might help too. Your categories all concern cupcakes, but you have non-cupcake items, such as cake items, and video games. Some of your product categories lack the handy sorting options. One thing says "Email us at" and then gives a web address, but clicking on the email address does not bring up the expected email client a real "mailto:" address would; but navigates to your Contacts page. Is there a 'search this website' search? I see the one for searching for products, but that's not really the same thing. It appears that that is what yer search does; so I suggest it say "Search This Site" instead.
The text
"We are the best on bakery cake !
It's the largest page on the web that helps you step-by-step to make your party cake, birthday cake, wedding cake, christmas cake and other celebrations cake."
seems a bit facetious. Are you really the largest, or are you lying to us? Amazon surely has more, although they aren't specialized. It doesn't really help you step-by-step, unless you buy one of the cookbooks. I don't really see any advice that doesn't simply point you to a product. "Christmas" should be capitalized. Do people really eat a lot of Christmas cakes?
Finally, is there anything that can be done to bring cupcakes into line with the recommendations of the Weston Price Foundation? They posit that primitive cooks would always do two of the following three things for better nutrition: 1) ferment grains, 2) soak grains overnight, or 3) sprout the grains. They also hold that grains other than white wheat flour are far more healthy. I'm sure you have no idea what I'm talking about (I blame lamestream media and the school system); but just sayin'.
