The perfect recipe to use up leftover egg yolks


Chewy lemon and white chocolate egg yolk cookies - a delicious way to use up leftover egg yolks

Egg yolk recipes are thin on the ground, unless you’re keen to make a homemade custard. And let’s face it, who wants the bother of making a custard (or one step further, an ice cream recipe) when you’ve just whipped up a pavlova (likely the reason you have leftover egg yolks in the first place)?

This egg yolk cookies recipe is the answer. It’s a basic method I’ve used for many years, and it’s a great way of using up leftover egg yolks when you’ve made a meringue. Really simple, very quick, and you can jazz it up with pretty much anything.

This recipe makes the kind of cookies that bend rather than snap, the kind that are chewy in the middle, the kind I love the most!


Can you freeze egg yolks? 


Can you freeze eggs?

First let’s clear up some eggy facts. Do NOT attempt to freeze egg yolks. I tried once, and the freezer did a weird thing to them. When they defrosted, they’d hardened, almost as if they’d been fried before freezing. Definitely not useable.

Egg whites can be frozen, coming out of the freezer just as perfectly as they went in. In fact, it’s probably worth making these egg yolk cookies precisely so you’ll have an excuse to freeze the egg whites. And make pavlova for Wednesday dinner, just because…

What else can you add to a cookie recipe?

These chewy cookies are pretty forgiving. Not only are they easy to make, they will accommodate any kind of alteration in flavours, so go crazy with your favourites:

  • Try adding juicy raisins instead of the chocolate
  • Chopped hazelnuts with milk chocolate chips are a classic cookie combination
  • Chopped dates and some toasted walnuts for something a bit more grown-up
  • Cranberries and white chocolate (this was a reader suggestion – let me know if you’ve tried anything that worked well)

Leave out the lemon in the last 3 suggestions, or substitute with orange zest.
