I was impressed with all of these cupcakes because not only were they tender and moist, they tasted like what they were supposed to. I can't tell you how many times I've had "vanilla" or "chocolate" cupcakes where all the flavor was in the frosting. That's too much work for frosting. These cupcakes were all delicious and flavorful and very rich; I couldn't finish them, but they're great for sharing.
I think the chocolate would be my favorite of the three; it's rich and dense but not overly sweet, which is something that can easily turn me off from a cupcake. I like the presentation of the cupcakes, too, with chocolate shavings atop the chocolate and red velvet, and little white chocolate chips (I think that's what they are) on top of the French vanilla cupcakes.
I'm not sure how limited "limited time" means, but look for them at Au Bon Pain.
red velvet cupcakes, which have the most calories at 400 each (350 calories for double chocolate cupcake, 320 calories for French vanilla).
