I wish I could claim this genius idea as my own, but I cannot. Jordan (our sister/sister-in-law), added Starbucks VIA to her cupcake batter and icing a couple of years ago to make the Best. Mocha. Cupcakes on earth.
And even though it's not my idea, I will sleep better at night once I pass this tip along. Because if you like coffee and chocolate (and cupcakes), you haven't really lived until you've tried one of these.
The whole mocha cupcake recipe is here, but the jist is that you add three packets of VIA to the cupcake batter and two packets of VIA to the frosting. You could use homemade frosting, but the Betty Crocker Buttercream is great in a pinch.
And then, you should probably pack up a platter or two and take them to various coffee-loving friends. If not, you might look at the plate a couple hours later and realize that you've eaten eight cupcakes. Not that that's happened around here or anything.
ps- We served these at the Denver Blogger Meetup and they were quite the hit!
