Being entirely free from flour and dairy, these little delicacies are an amazing lactose-free and gluten-free treat. They offer a delicate crunch on the outside, a satisfying chewiness on the inside, and a rich, nutty flavor that will have everyone reaching for more.

They are light, airy, and boast a distinctive texture that sets them apart from traditional cookies. Ideal for holiday platters, afternoon tea, or simply a sweet indulgence, these walnut meringues are a versatile addition to any baker’s repertoire.

🥘 Ingredients

For a small batch of about 20 cookies, you’ll need just two egg whites and a couple of pantry staples. This recipe is easily scalable, so if you’re looking to make more or experiment with different types of nuts, simply double the quantities of egg whites, ground nuts, and sugar. Remember, using fresh, room-temperature egg whites is key for achieving those perfect stiff peaks!

• Egg Whites: The star of our meringue! Aim for large egg whites. Separating them when cold and then letting them come to room temperature (about 30 minutes) helps them whip up faster and with more volume.
• Ground Walnuts: These provide a wonderful earthy flavor and a slight chewiness, complementing the sweetness of the meringue. Ensure they are finely ground for the best texture.
• Powdered Sugar (Confectioners’ Sugar): Crucial for the delicate texture of meringues. Unlike granulated sugar, powdered sugar dissolves more easily into the egg whites, resulting in a smoother, more stable meringue and a less grainy finish.

The synergy of these three ingredients creates a cookie that is naturally sweet, subtly nutty, and incredibly satisfying. Plus, the absence of flour and dairy makes them a fantastic option for those with sensitivities or preferences for gluten-free and lactose-free desserts.

🍽 Equipment

Having the right tools can make your baking experience smoother and more enjoyable. For these walnut meringue cookies, you won’t need anything overly specialized. Here’s a list of essential equipment to get you started:

• Baking Sheet: Essential for baking your cookies evenly.
• Parchment Paper: Prevents sticking and makes cleanup a breeze. Don’t skip this for meringues!
• Mixer or Food Processor: A handheld electric mixer or a stand mixer is crucial for whipping egg whites to stiff peaks quickly and efficiently.
• Piping Bag (Pastry Bag): For neatly piping the meringue mixture onto the baking sheet.
• Mixing Bowl: Make sure it’s clean and grease-free to ensure your egg whites whip up properly. A glass or metal bowl is often preferred over plastic.
• Tablespoon: For measuring and scooping.
• Cookie Jar: For proper storage of your freshly baked cookies.

Ensuring your equipment is clean and dry, particularly your mixing bowl and whisk attachments, is paramount when working with egg whites. Even a tiny bit of grease or egg yolk can prevent your whites from achieving stiff peaks.

🔪 Instructions

These delightful cookies come together very quickly, so it’s a good idea to perform all the necessary prep work upfront. Pre-heating the oven often takes longer than preparing the cookie batter itself, saving you precious time and ensuring your oven is at the ideal temperature when your mixture is ready.

1. Preheat Oven & Prepare Baking Sheet: Preheat your oven to 302 °F (150 °C) using the top/bottom heat setting. Line a baking tray with parchment paper. This step is crucial for preventing the meringues from sticking and for easy removal.
2. Whip Egg Whites: In a clean, dry mixing bowl, begin beating the room-temperature egg whites with your mixer on medium speed. Gradually increase the speed to high. Continue beating until the egg whites form stiff, glossy peaks. This means when you lift the whisk, the peaks hold their shape firmly and don’t flop over.
3. Incorporate Dry Ingredients: Once the egg whites are stiff, gradually add the ground walnuts and powdered sugar. Add them in small batches, gently folding them into the egg white mixture with a spatula. Be careful not to deflate the air you’ve just whipped into the egg whites, as this is what gives meringues their light and airy texture. Continue folding until the ingredients are just combined and the mixture is thick and uniform.



4. Pipe Cookies: Once the thick mixture is ready, carefully transfer it into a piping bag. You don’t need a special nozzle; simply cut off the very tip of the piping bag to create an opening of about ½ inch (1-1.5 cm). Pipe tiny, consistent heaps of the mixture onto the prepared baking tray. Ensure you leave enough space between each cookie, as they will spread slightly during baking. Consistent sizing helps them bake evenly.
5. Baking & Texture Note: Since this recipe is designed to be made without cream of tartar, these meringues will be wonderfully chewy and moist on the inside, with a delicate crispness on the outside. They tend to spread a bit more in width than they rise in height, creating a softer, more rustic meringue compared to those made with a stabilizer.
6. Bake Until Golden: Bake the cookies for 20-25 minutes. The exact baking time may vary depending on your oven, so keep a close eye on them. The cookies are ready when they turn a beautiful, light golden-brown color. This indicates they are properly cooked through and will develop the desired texture.
7. Cool & Store: Once baked to perfection, take the cookies out of the oven and let them cool completely on the baking tray. Meringues are delicate when warm, and cooling helps them firm up. After they’ve cooled, transfer them to a well-sealed cookie jar or airtight container and store them in a cool, dry place.
8. Pro Tip for Storage: To prevent the cookies from sticking to the jar or to each other, I highly recommend lining the cookie jar with greaseproof or parchment paper before adding the cookies. This simple trick makes retrieving them a joy, ensuring you won’t get annoyed when you want to enjoy a bite!

📖 Variations

One of the most exciting aspects of this walnut meringue cookie recipe is its versatility. You can easily adapt it to create a variety of flavors and textures. Here are some ideas to inspire your culinary creativity:

• Different Ground Nuts: The easiest way to vary these cookies is by swapping out the walnuts for other ground nuts. Grated almonds, pecans, pistachios, or even hazelnuts are particularly suitable. Each nut brings its unique flavor profile.
• Coconut Version: If you’re a fan of coconut, try a version with grated coconut. The tropical flavor pairs wonderfully with the sweet meringue. For a dedicated coconut meringue recipe, check out my coconut kisses (meringue) cookie recipe.
• Chocolatey Twist: Fold in a tablespoon of cocoa powder with the powdered sugar for a chocolate meringue. You could also gently fold in mini chocolate chips at the very end of the mixing process.
• Citrus Zest: Add a teaspoon of finely grated lemon or orange zest to the egg white mixture for a bright, refreshing flavor.
• Extracts & Spices: Introduce different extracts like almond extract (to enhance nut flavor), vanilla extract (a classic), or peppermint extract for a festive touch. A pinch of cinnamon, nutmeg, or even a tiny bit of cardamom can add warmth and complexity.
• Food Coloring: For holidays or themed events, add a few drops of food coloring to the egg whites before whipping them to create vibrant, colorful meringues.
• Drizzles & Dips: After baking and cooling, drizzle your meringue cookies with melted chocolate, caramel, or a simple glaze for an extra layer of decadence.

Don’t be afraid to experiment! These simple variations can transform your classic walnut meringues into a new favorite dessert every time.

🙋🏻 FAQ

Can you make meringue cookies without cream of tartar?

Yes, absolutely! The recipe described here is made completely without cream of tartar or any other baking powder. Omitting cream of tartar results in a slightly different texture: the cookies will be wonderfully chewy and moist on the inside, contrasting beautifully with a delicate crispness on the outside. Meringue cookies made with cream of tartar, on the other hand, tend to be thoroughly crisp and dry throughout. The choice often comes down to personal preference for texture.

How to freeze egg whites?

Freezing egg whites is an excellent way to preserve them for future baking projects. An ice cube tray is the most convenient method for freezing egg whites because it allows you to freeze them in pre-portioned amounts, making it easy to know how many you have for future recipes. Once frozen solid, you can transfer the egg white cubes to a freezer-safe bag or container. A good rule of thumb is that two teaspoons of egg white roughly equal one large egg white. When ready to use, simply thaw them in the refrigerator overnight or at room temperature for a few hours.

Why didn’t my egg whites stiffen?

The most common reasons for egg whites not stiffening are the presence of fat (even a tiny drop of egg yolk or grease from your bowl/utensils) or using cold egg whites directly from the fridge. Always ensure your mixing bowl and whisk attachments are immaculately clean and grease-free. Also, allow your egg whites to come to room temperature before whipping.

How long do meringue cookies last?

When stored properly in an airtight container in a cool, dry place, these walnut meringue cookies can last for up to 1-2 weeks. Humidity is the enemy of meringues, so ensure the container is well-sealed to prevent them from becoming sticky or soft.

Can I use granulated sugar instead of powdered sugar?

While technically possible, powdered sugar is highly recommended for meringues. Its finer texture dissolves more smoothly into the egg whites, resulting in a more stable, glossy meringue and a melt-in-your-mouth texture. Granulated sugar can leave your meringues with a slightly grainy texture.
