These are so good, and very sweet! I was amazed at how much ganache each cupcake could hold, but still had quite a bit left over. The buttercream was very easy to work with and piped well, and it held its shape.
I made this recipe for a customer, per her request, and I found that you can easily halve the ganache quantity but double the frosting quantity. You will still have enough ganache to make a double batch of frosting. Its so sweet you don't need a lot of filling per cupcake. Also, if you're not serving them soon after you fill them, make a dam with some of the frosting before filling. Before I added the cream when making the frosting I took some frosting out and used corn starch to flatten and roll it out a bit. Then I used an apple corer to make a little hole in the cupcake. Then I put a piece of the flattened frosting inside the hole. I finished making the frosting by adding cream then added it on top. By doing this it makes the filling stay put and not make the cupcake mushy.
DD and friends are big Harry Potter fans. So we HAD to make these cupcakes. The cake has more of a muffin texture. I wish they were a little lighter. The ganache helps, but can make them mushy if you make them ahead of time. While they were good, they were a little time consuming for the end result. Not against making them again, but we will tweak and continue looking for those perfect Potter cupcakes!
