How often do you end up with leftover egg yolks when cooking and baking? Unfortunately, too often. And then you stand there, have a lot of yolks leftover, and wonder: "What to do with leftover egg yolk?"
It would be a shame to have to throw them away! That's why I want to give you a great idea of what to do with leftover egg yolk and how to bake delicious Christmas cookies from egg yolks!
Since I've used up 6 egg whites for the grannies egg white cookies (Kokosbusserl), I have 6 egg yolks leftover. Now I thought I'd write a little post about some fabulous walnut cookies that will use up those 6 extra yolks!
Jump to:
🥘 Ingredients
- 6 Egg yolks
- 4.23 oz (120 g) Powdered sugar
- 3 teaspoon Vanilla sugar
- 1.5 tablespoon Rum
- 1.5 Pinches of salt
- 10.58 oz (300 g) Ground walnuts (replaceable with ground almonds or hazelnuts)
- OPTIONAL: baking wafers (Just like with the grannies coconut kisses cookies, I left out the baking wafers. Simply a matter of taste.) 🙂
The nice thing about these cookies is that they don't require cream, butter, wheat, or milk as an ingredient, which is excellent for many people who have food allergies!
🍽 Equipment
- Handheld electric mixer
- Wooden spoon
- Mixing bowl
- Pastry bag
- 2 Baking paper sheets
- 2 Baking trays
🔪 Instructions
Before you start the preparation, preheat the oven to 302 °F / 150 °C (top/bottom heat). Combine the leftover egg yolks with powdered sugar, salt, and vanilla sugar and beat them using a hand mixer until foamy.
In the next step, fold in the rum and the grated walnuts (almonds or hazelnuts) with a wooden spoon into the foamy mixture.
Now fill the mixture into a pastry (piping) bag and create tiny mounds onto the baking tray lined with baking paper.
If you have opted for the variant with baking wafers, pipe the mass directly onto the wafers. Fancy decorating your cookies? Add a walnut (almond or hazelnut) on top as a decoration. Once a baking sheet is full, bake the cookies on the second rack from the bottom for about 20 minutes. In total, you get about 40 delicious walnut cookies out of the mass.
Let the cookies 🍪 rest and cool after baking. After that, you can store them in an airtight container in a cool and dry place. Serve these delicious gluten-free egg yolk cookies together with the previously prepared coconut kisses cookies with coffee or tea. Enjoy them with good music and pleasant company!

Sorry but what is vanilla sugar? Or more importantly, what can you sub for it? Vanilla extract and sugar maybe?
Nora
Thank you for the great question, Kristen! Vanilla sugar is made from sugar and vanilla pods or sugar mixed with vanilla extract. It is widely used in Austrian kitchens. As a substitute, you can use vanilla syrup, vanilla paste, sugar beet syrup, but also ground Tonka beans. Hope that gives you some alternatives!
