I'm making some bunny cupcakes for good Friday and, was thinking off adding a Nutella filling to my vanilla cupcakes using my Bismarck tip and wondering if anyone has done this and, if so, did you just use straight Nutella, melt it over double boiler to make it easier to inject, add some heavy cream to make it a ganache? Just wondering what would work/taste best.
I'm looking for something that is kid and adult friendly.
I've never used Nutella, but to make peanut butter filling, I add 1/2 cup of peanut butter to my buttercream filling recipe and it's perfect. I would imagine that Nutella would be about the same - you will just have to adjust the amount to your tastes.
You could warm the Nutella slightly but I normally just put it in the cupcakes as it comes out of the jar. I stir up the contents and then fill my bag. If you like you can use a coupler and tip #21 and fill that way. I don't care for the bismark tip as it gets filling around the outside of the tip since it does not use a coupler. HTH.

My jar only says not to put in the fridge. I googled and, there are lots of recipes or references to warming nutella so, not sure.
Nutella right out of the jar is pretty stiff. You might need to warm it for a few seconds to soften it up enough to inject. I even had to warm it a bit to spread it for filling between cake layers.
I have also used a store brand version of Nutella and it was softer. It's probably the perfect consistency to inject.
