I'm about to make filled cupcakes for the first time. It'll be this cupcake from Ming Makes Cupcakes. The filling is basically lemon curd, i.e. a custard. Most tutorials on making filled cupcakes mention either:
- Spritzing it in with a piping bag, which I don't have. Also apparently it only allows for a small amount of filling.
- Cutting a cone out of the cupcake, filling the hole, and then replacing the cone - this seems fiddly and I'm kind of a klutz and it sounds like a recipe (badoom-tsch) for having half my cupcakes fall apart.
One last how-to mentioned that it's possible to bake fillings that won't be absorbed into the batter (candy, an Oreo, etc) inside the cupcake. I'm wondering: would this be possible with lemon curd? Since it's a custard, I'm guessing it shouldn't dissolve in the heat.
Does this sound feasible or has anyone tried this? If so, any things I should be careful of? E.g. should I make the custard thicker so it keeps together inside the batter? Or thinner so it finishes cooking while baking? If so how to make it keep together until the batter sets? (I'm guessing chilling thoroughly? Freezing is probably a bad idea though.)
