Keto Forgotten Cookies

If you have a giant sweet tooth, here’s a recipe you’ll be making for a long time to come: keto forgotten cookies! The name may sound odd, but let your curiosity be the reason you give them a try.

These low-carb forgotten cookies are a twist on the classic meringue recipe, as they are crispy, airy meringue cookies filled with pieces of pecans and sugar-free chocolate chips.

This recipe employs beaten egg whites and uses a sugar-free sweetener rather than real sugar—simple ingredients that make keto meringues a delicious part of a complete keto diet. You’re welcome!

The sugar-free meringue cookies are low-calorie cookies, with only 20 calories per cookie. And at .3 g net carbs, they’re virtually carb-free cookies that still make a sweet treat that the whole family will enjoy.

They might even forget they’re eating low-carb cookies to begin with!

Keto Forgotten Cookies

The name “forgotten cookies” originates from an unusual baking process. These cookies are made in under 15 minutes, placed in the oven, and then “forgotten” until the next morning.

After turning the oven off, the cookies continue to bake overnight as they cool down to a low temperature. When you wake up the next morning, they’ll come out of the oven with a glossy, crispy exterior, soft peaks, and a fluffy center.

It’s hard to resist not eating cookies as soon as they’re finished baking, so the thought of leaving cookies in the oven until the next day, let alone keto meringue cookies, will surely test your patience.

But I promise you’ll be rewarded with an amazing treat that is 100 percent waiting for.

Here are the ingredients you need to make these keto-friendly forgotten cookies.

• Egg whites (room temperature)
• Cream of tartar (added for extra stability)
• Vanilla extract (Pro-tip: Use white vanilla extract if you have it.)
• Granulated sugar substitute
• Salt
• Finely chopped pecans
• Sugar-free chocolate chips (finely chopped or mini chocolate chips)

How To Make Keto Forgotten Cookies

The first step is to line a baking sheet with aluminum foil, grease it with unsalted butter, and preheat the oven to 350 degrees F.

Using a food processor, finely chop the pecans into tiny pieces and set them aside. Then do the same with the sugar-free chocolate chips, unless you use sugar-free mini chocolate chips. 

In a large, clean mixing bowl, add the room-temperature egg whites, cream of tartar, and salt.

Using an electric hand mixer or stand mixer with a whisk attachment, beat the mixture on medium speed until it’s foamy and just beginning to turn opaque white.

While continuing to whip the egg mixture, add in the vanilla extract.

Very slowly, about a teaspoon at a time, start adding in the granulated sugar substitute while continuing to whip the egg whites.

After adding in all the granulated sugar substitute, raise the mixer to medium-high speed and whip until the meringue is glossy and forms stiff peaks.

Using a spatula, fold the chopped pecans and the sugar-free chocolate chips.

Drop the cookie dough by spoonfuls onto the prepared baking sheet.

Put the cookies in the preheated oven and then turn the oven off.

Leave the cookies in the oven overnight. Keep the door closed for about 8 hours so the heat doesn’t escape. DO NOT OPEN THE OVEN DOOR UNTIL THEY’RE READY; they are worth waiting for.

Store leftovers in an airtight container on the kitchen counter for up to 1 week or freeze them for up to 3 weeks.

Helpful Tips When Making Forgotten Keto Cookies

To ensure very stiff egg whites, be sure that all of your equipment is extremely clean and free of any grease. Any residue will not allow the egg whites to rise.

Something to remember when you separate your eggs is that they do so more easily when the eggs are cold, but you’ll achieve stiffer peaks if you allow the egg whites to come to room temperature. So plan accordingly.

Be sure that the egg whites are free of any trace of yolks. Otherwise, your meringues will never fully form. The fat from the yolks will prevent them from rising.

I recommend that you separate each egg into a small bowl, then transfer each egg white to the mixing bowl. This extra step will keep all the egg whites free of any yolk protein in the event a yolk breaks when you are separating the eggs.

In order to get pieces of chocolate and pecans in every bite, I recommend you run the pecans and chocolate chips quickly through a food processor to ensure they’re as small as possible without becoming microscopic.

The addition of cream of tartar gives the cookies extra stability and should not be left out.

Best Sugar Substitutes

As far as which sugar substitute to use for these sugar-free forgotten meringue cookies, I have a few recommendations.

Lakanto Monk Fruit Classic is their white granulated version, and it’s my go-to option whenever a recipe calls for granulated white.

It’s my favorite since the texture and flavor are what I have found to be the closest to real sugar.

The brand Swerve which is an erythritol blend, also makes a great white granulated sugar substitute. It’s a great option that’s more accessible to many as it can be found in most grocery stores now.

You could also use the stevia and erythritol-based brand Pyure if you prefer to use a granulated white stevia-based sweetener.

I, however, have not tested this recipe using Pyure and cannot guarantee the same results since you are using half the amount since it’s doubly sweet.

Lastly, if you can’t easily find a more natural sugar substitute, you can also use Splenda with great success.

I know not everyone would agree with me here, and I respect this, but in my book, it’s still better than regular sugar.

Plus, I find it doesn’t have much of an aftertaste. It’s also more economical, so there’s that too.
