I'm planning to make crème brûlée-flavored French macaroons, which will consist of vanilla-flavored macaroons, topped with caramelized sugar for the shatter-y effect, and a vanilla bean custard filling. However, I'm unsure of the best way to cook the custard filling, since I'm not after the same consistency as the custard in real crème brûlée; I'd like something a bit softer and more spreadable. I doubt that cooking the custard the same way for a shorter period of time would work, but I also don't have much experience cooking crème brûlée, so any ideas would be appreciated!

  • Have you tried following an existing recipe for macarons filled with crème brûlée or other custards?

I think your flavor ideas seem fine, I'd advise against a custard filling for two reasons. First, custard is squishy, even if you make it harder it's going to squish out when the macaron is bitten into, which isn't the result you want. Second, the excess moisture in the custard could make the macarons soggy, also not the result you want.

Almost all the macaron fillings I know of use chocolate ganache or butter cream fillings because they have the right combination of spreadibility and resilience, and their low moisture content will keep the macarons from getting soggy. I would suggest you change your approach to use one of these two options. You could try making a vanilla butter cream with toasted white sugar to get a caramel flavor, it's an extra step but makes a big difference flavor-wise.

If you want to try a custard then a cornstarch (aka cornflour depending on where you are) thickened custard is likely the way to go as you can get a thicker set than an egg yolk custard, and it's easier to modify through experimentation to find out how much you will need to get the consistency you want when cooled. You will also want to give the inside of each half a thin layer of white chocolate to prevent them from absorbing moisture from the custard.


Building on GdD's suggestion that a custard might be too wet for the meringue, how about using a white chocolate ganache instead? You can make it at least reminiscent of custard by adding vanilla bean seeds. And if you make a ganache with egg yolks, you'll get some of the egg-y taste of custard.
