This is from the Raspberri Cupcakes site, which has lots of gorgeous, fun, delicious recipes.
And then, of course, there's the world's largest gummy bear (not sure if this is in any way associated with Haribo, but it does exist and can be purchased at the Vat 19 website).
(The world's largest gummy bear, shown above, weighs 5 pounds, is 9.5 inches tall and has a 6,120 calorie count. Wow)!
