Keto Peanut Butter Cookies – Chewy, Crunchy & Crumbly!

Keto Peanut Butter Cookies – Chewy, Crunchy & Crumbly!

Today we’re making a batch of fantastic peanut butter cookies that are chewy but crunchy, crumbly but just right. Here’s the deal, these one-biters are not only a beauty but also a flourless, three-ingredient treat that takes less than 15 minutes to put together. How cool is that?

Now when you hear the words peanut butter, you know what to expect, a nutty, slightly sweet, buttery cookie with fluttering flavors of warm cinnamon — that’s a good cookie right there and the best companion for a cold glass of milk or an iced latte.

Let’s start from the beginning. I love baking, but sometimes I feel cookies are too much work; I need to be motivated, especially with complicated recipes for cookies you have to let cool and decorate, you know what I mean, the Christmas kind. Well, today’s cookies are precisely the opposite; they’re for the laziness in me.

Three Ingredients and One Optional Ingredient

Our cookies are based on peanut butter, so here’s where you must make your first decision, plain or crunchy? Also, make sure you use 100% peanut butter. There are lots of artisan nut butters now, and they are much better than the old Jiffy. Commercial peanut butters might have added sugar, or worse, trans fats. A good nut butter should only be made with pressed nuts.

Then we’ll need a large egg. One ingredient to bring them all, and in the oven and bind them. Be kind and source eggs from pasture-raised hens with no antibiotics, they’re not only more sustainable, but they’re also tastier.

Now you must choose your sweetener, and for baking treats, I use Stevia; it’s natural and works like a charm. Erythritol and Swerve work great, too, so see what you have in hand. Are you into the keto lifestyle? Know your sweeteners.

There’s a fourth ingredient, and thanks to your reviews and comments, we’re making it optional — cinnamon powder. Cinnamon will add warmth and a pleasant fragrance to our cookies, but we can substitute it with other things as the recipe’s flavoring agent.

If you want to taste the peanut butter and nothing else, then you’re all set, but you can also substitute the cinnamon with a few drops of vanilla extract and even with a pinch of ground cardamom for an exotic feel!

As for the shape and size, you can make small one-bite size balls with your hands and press your cookies with a fork to score them and give them a nicer presentation. Then they’re ready to hit the oven.


The Magic of Substitutions

We’ve talked above about substituting the cinnamon powder for other flavorings, and that alone will change the flavor profile of our chewy cookies, but we’re just getting started.

What if we changed the recipe’s main ingredient to create an entirely different cookie? I’m talking about swapping the peanut butter for one of all the amazing nut butters that have become so popular recently. Check out this list:

And this is just the peak of the iceberg! Picture all the chewy cookies you could make. And you need not change the recipe below at all.

Now combine the different nut butters with other flavorings and spices, and you’ve got yourself a complete repertoire of 15-minute keto cookies to make for every occasion.

What You’ll Need?

Back to our recipe, to make these beauties, you’ll need an oven. Remember to preheat it to 350°F at least fifteen minutes before baking the cookies.

You’ll also need a baking sheet lined with parchment paper, and of course, a medium-sized mixing bowl to combine the ingredients. You might also want to have a silicone spatula in hand to fold the batter.

Other than that, we’re all set. Let’s make ourselves the tastiest peanut butter cookies ever. Low-carb, fast, easy and delicious. What’s not to love?

Additionally , they know what type of cars are prone to higher risk plus the higher risk they have the higher your premium rate.

Another thing I've really noticed is always that for many people, below-average credit is the reaction of circumstances further than their control. For example they may have already been saddled with illness so they have excessive bills for collections. It could be due to a work loss or perhaps the inability to go to work. Sometimes divorce process can truly send the money in the wrong direction. Many thanks for sharing your thinking on this site.
