I also made them! I couldn't get Soy Milk powder in time so I used Soy Protein powder and and Egg Replacer... they were still good! I have never heard of hazelnut agave! I'll be on the look out for it though!
I was going to make these, but in the book Alicia mentioned they need to be eaten right away. Did you find that to be true or did they keep for a few days? I know my husband and I can't eat them all in one sitting (well we probably could...haha) so I could only make them if we had a few days to eat them.
I made these for a non-vegan birthday party and they were so well-loved by the meat eaters that they kept all the leftovers for themselves! I was thrilled :) :) :) I too love the frosting! Melissa-- I found that they keep for a good 2 days before you probably don't want to look at them any more. Maybe they'd stay even longer if you popped them in the fridge. They're so incredibly moist that I'm sure they won't get dried out! I made them with maple syrup as I didn't have the agave for both the cupcake and frosting. Also, I didn't have any powdered soy and did not think the frosting was runny in the slightest. Perhaps it was because of the maple syrup. :)
Made these again tonight. sub coconut oil for the safflower oil since i ran out and the cupcakes turned out well. That being said, I didn't have enough agave for the frosting so I used half agave, half brown rice syrup and no soy milk powder...what a mistake! the frosting wasn't runny but it did taste kind of off...i think mixing agave with rice syrup was a bad idea as the flavors are totally different. i'll probably just eat the cupcakes without the frosting.
