The messiest and most time consuming part of this recipe is the chopped sugared walnuts topping. I made one batch with and one without. Both went of equally as well. The cupcake and frosting, though? A cinch to whip together!
I actually had a coworker tell me, days later, that she was still telling her friends about these cupcakes.
The recipe I used is from Vegan Cupcakes Take Over the World. Go get it. Seriously! How many examples of how easy and amazing this book is do I need to give you?
