In Christmas baking, you often have egg whites leftover from another recipe.
So, what to do with Leftover Egg Whites? To avoid tossing them away here's a wonderfully tasty, very quick, easy-to-make cookie recipe that will turn your leftover egg whites into delicious little cookies.
The fantastic thing about this recipe is that it only requires three ingredients.
In addition, these cookies are free from flour and dairy, which makes these little delicacies an amazing lactose- and gluten-free treat.
With two egg whites left over from another recipe, you can find the ingredients for a small batch of cookies here (about 20 of them). Double the number of egg whites, ground nuts, and sugar if you feel like making more cookies or making a variation with a different type of nuts.
- 2 Egg Whites
- 5.29 oz (150 g) Ground Walnuts
- 5.29 oz (150 g) Powdered Sugar
- Baking Sheet
- Parchment Paper
- Mixer or Food Processor
- Piping Bag (Pastry Bag)
- Mixing Bowl
- Cookie Jar
Since these cookies are really quick to prepare, I recommend you do all the necessary prep work first. This prep will save you time, as pre-heating the oven usually takes longer than preparing the cookies.
Preheat the oven to 302 °F // 150 °C top/bottom heat and cover the baking tray with baking paper.
Start beating the egg whites with the mixer until stiff. Gradually add the grated walnuts and powdered sugar.
Once the ingredients are well combined, you can pour the thick mixture into a piping bag. You do not need a special nozzle for the pastry bag. It is sufficient to cut off the tip of the piping bag a little bit.
Now pipe tiny heaps of the mixture onto the baking tray lined with baking paper. Make sure to leave enough space between the heaps so that they do not merge during baking.
Since this particular recipe works without cream of tartar baking powder, they run more in width than in height and are less firm.
The baking time is between 20-25 minutes, depending on your oven. In any case, please keep them in the range until they turn a light brown color.
When the cookies reached the correct color, take them out of the oven and let them cool down.
After that, you can store them in a well-sealed cookie jar in a cool place.
As always, I recommend lining the cookie jar with greaseproof paper before you put the cookies in. The greaseproof paper helps a lot that the cookies won't stick anywhere in the cookie jar.
So you won't get annoyed when you want to have a bite.
The easiest way to vary these cookies is to make them with different kinds of groundnuts. Grated almonds, pecans, and even peanuts are particularly suitable here, as also coconut. If you want to try the grated coconut version, try my coconut kisses (meringue)cookie recipe.
How Long Do Meringue Cookies Last?
When stored in a cool, dry place, meringue cookies stay fresh for up to 2 weeks. If frozen, they can last a couple of months.
Are meringues supposed to be chewy and crunchy?
Yes, and yes. If baked properly, meringue cookies have a lightly crunchy exterior and a soft, chewy interior.
Can you freeze meringue cookies
Yes. Personally, fresh meringue cookies are always the best. However, you can freeze these meringue cookies for up to 3 months.
Can you make meringue cookies without cream of tartar?
Yes! The recipe described here is made completely without cream of tartar baking powder! Omitting the cream of tartar baking powder makes the cookies chewy and moist on the inside, but nice and crispy on the outside. Meringue cookies with cream of tartar are, on the other hand, thoroughly crisp and dry.
What does cream of tartar do in cookies?
Cream of tartar helps stabilize whipped egg whites, prevents sugar from crystallizing, and acts as a leavening agent for baked goods. If you're halfway through a recipe and find that you don't have any cream of tartar on hand, there are plenty of suitable replacements.
How long do egg white last in the fridge
Egg whites will keep in the fridge for up to two days.
How to freeze egg whites?
An ice cube tray is the best way to freeze egg whites. The tray helps not to get confused with the quantities. Otherwise, two teaspoons of egg white equal one large egg white.
