Introduction:
If you’re following a keto diet or simply looking for a low-carb, high-protein dessert option, these Keto Meringue Cookies are the perfect treat. These light, crispy cookies are made with just a few simple ingredients, making them incredibly easy to prepare. With their airy texture and subtle sweetness, they offer a delightful contrast to heavier, more indulgent desserts, and they fit seamlessly into a keto or low-carb lifestyle.
Meringue cookies, often associated with French pastries or holiday sweets, are usually made with egg whites and sugar. However, in this keto-friendly version, sugar is replaced with a low-carb sweetener, which ensures that each cookie is delicious but still compliant with the dietary restrictions of the keto diet. Additionally, they’re naturally gluten-free, dairy-free, and incredibly low in SmartPoints, making them a perfect dessert for those following the Weight Watchers program as well.
Whether you’re craving something light and crispy, or need a low-carb snack to satisfy a sweet tooth, this recipe will give you the perfect solution. Read on for a detailed guide to making these Keto Meringue Cookies, including the step-by-step instructions, helpful tips, nutritional breakdown, and how to make them work for your weight loss goals.
Ingredients:
To make these Keto Meringue Cookies, you’ll need the following ingredients:
- 3 large egg whites (make sure they’re at room temperature for best results)
- 1/2 tsp cream of tartar (this stabilizes the egg whites and helps them achieve the right texture)
- 1/2 cup powdered erythritol (or another preferred keto-friendly powdered sweetener like monk fruit sweetener or stevia blend)
- 1 tsp vanilla extract (for flavor)
- Pinch of salt (optional, but it balances the sweetness)
- 1/4 tsp lemon juice (optional, to enhance flavor and help stabilize the meringue)
Optional Add-ins:
- 1/4 tsp almond extract (for a unique flavor profile)
- A few drops of food coloring (if you want to make your meringues more colorful)
- Chocolate chips or cocoa powder (to make chocolate-flavored meringues)
Note: Make sure your egg whites are free from any yolk and your mixing tools are completely clean and free from any grease or oil to ensure that the meringues whip properly.
Equipment:
- Electric hand mixer or stand mixer (preferable for whipping the egg whites)
- Baking sheet (lined with parchment paper or a silicone mat)
- Mixing bowl (preferably glass or stainless steel, as plastic can sometimes retain oils that interfere with whipping)
- Measuring spoons and cups
- Spatula (for scraping the bowl and ensuring no mixture is wasted)
- Oven (for baking the meringues)

Instructions:
Step 1: Prepare Your Ingredients and Equipment
Start by gathering all of your ingredients and equipment. This recipe requires precision and timing, so it’s essential to have everything ready before you begin. Set your egg whites out to come to room temperature—this is crucial for them to whip to full volume. Preheat your oven to 200°F (93°C). The low temperature is key to allowing the meringues to dry out without browning.
Next, line a baking sheet with parchment paper or a silicone baking mat. This will prevent the meringues from sticking and help them hold their shape as they bake.
Step 2: Whip the Egg Whites
In your mixing bowl, add the egg whites, cream of tartar, and a pinch of salt. Use your electric mixer to begin whipping the egg whites on a medium speed. As the egg whites start to foam and turn frothy, increase the speed to high.
Whip the egg whites until they form soft peaks, which should take about 3-4 minutes. You’ll know they’re ready when you can hold the beaters up, and the egg whites form gentle peaks that curl over.
Step 3: Add the Sweetener and Flavors
Once your egg whites have reached soft peaks, gradually add in the powdered erythritol or your chosen keto-friendly sweetener, about 1 tablespoon at a time. Make sure to add the sweetener slowly to ensure the egg whites don’t deflate.
Once all the sweetener is added, continue whipping the meringue mixture until stiff peaks form. This means the peaks should stand up straight when you remove the beaters from the mixture, and the meringue should appear glossy and firm.
At this point, add the vanilla extract and, if using, the lemon juice and any optional extracts or food coloring. Mix gently until the meringue is smooth and evenly flavored.
Step 4: Pipe or Spoon the Meringue
For perfectly shaped meringue cookies, you can use a piping bag fitted with a star or round tip. However, if you don’t have a piping bag, you can simply spoon the meringue mixture onto the prepared baking sheet. Make sure to space each meringue about an inch apart to allow for even baking.
You can make small or larger meringues depending on your preference. Just keep in mind that smaller meringues will bake more quickly.
Step 5: Bake the Meringues
Place the baking sheet into the preheated oven and bake the meringues for 90 minutes to 2 hours. The low baking temperature ensures the meringues dry out without browning. After 90 minutes, check the meringues. They should feel dry and crisp to the touch, and they should easily lift off the parchment paper.
If the meringues are still soft in the center, continue baking for another 30 minutes. Be patient—this step is crucial for achieving the perfect crisp texture.
Step 6: Cool the Meringues
Once the meringues are baked, turn off the oven but leave the door slightly ajar. Allow the meringues to cool in the oven for another hour. This helps them firm up and ensures they don’t crack due to sudden temperature changes.
After they’re completely cool, transfer the meringues to an airtight container for storage.

Why These Meringue Cookies Work for Keto and Weight Watchers:
1. Low in Carbs:
Keto diets thrive on low-carbohydrate foods, and meringue cookies are the perfect match for this. By using erythritol or another low-carb sweetener, these cookies provide the sweet taste of dessert without the added sugars that can interfere with ketosis or weight loss.
2. Protein-Rich:
Egg whites are naturally high in protein, making these cookies an excellent source of this essential nutrient. Protein is key to maintaining muscle mass while on a keto diet, and these cookies offer a satisfying, protein-packed treat that can help you reach your goals.
3. Perfect for Weight Loss:
These meringue cookies are filling and satisfying while being incredibly low in calories and SmartPoints. This makes them an ideal snack for anyone on a weight loss journey, as they can help curb cravings without sabotaging your efforts.
4. Easy to Make and Customize:
Meringue cookies are simple to make, and this recipe allows for easy customization. Whether you prefer chocolate, almond, or classic vanilla meringues, you can modify the flavors to suit your tastes without increasing the carb count.
Tips for Success:
- Ensure Clean Tools: Make sure your mixing bowl and beaters are completely clean and free from any oils or grease. Even a small amount of oil can prevent the egg whites from whipping properly.
- Use Powdered Sweetener: For the best texture, always use powdered sweetener instead of granular. Granular sweeteners won’t dissolve as smoothly, and they can lead to a gritty texture in the final product.
- Be Patient While Baking: Low and slow is key when making meringues. Don’t rush the baking process—bake at a low temperature and let the meringues cool gradually in the oven to get the crisp, melt-in-your-mouth texture.
- Avoid Humidity: Meringues are sensitive to humidity, so it’s best to make them on a dry day. If your kitchen is particularly humid, consider using a dehumidifier or turning on the air conditioner while making the meringues.
