These delicious peanut butter cookies are low carb, sugar-free, and absolutely delicious! However, baking these Low Carb Peanut Butter Cookies can be quite costly. In fact, the last time I made them, they cost me $2800! You probably think I'm joking, but I'm not.

As usual, I had my furry friends (Mr. Whiskers and Winston) in the kitchen, begging for a sample of the sugar-free cookies that I was baking.
Since dogs are known to love peanut butter, I happily obliged. Within thirty minutes, Winston began vomiting, and I had to rush them both to the animal hospital.
$2800 later, I learned that dogs can't digest sweeteners. Sweeteners, it turns out, are actually very toxic to dogs, who knew?
So, enjoy these low carb peanut butter cookies, but please don't share them with your dogs. On a side note, cats are not affected in the same way.
Why This Recipe Works
The basic recipe for sugar-free peanut butter cookies is pretty simple. All you need is peanut butter, eggs, and some granulated sweetener like Splenda, Xylitol, or Truvia.
Those are the basic ingredients, but this recipe definitely needed some improvements. For one thing, it needed more flavor.
To enhance the flavor, try mixing in some vanilla or banana extract. After all, even Elvis knew that peanut butter and bananas go hand in hand; peanut butter and banana was Elvis' favorite sandwich.
Another common complaint with sugar-free and flour-free cookies is that they're too crumbly. Adding baking powder, and coconut oil is a great solution. To add a little crunch, think about adding some ground peanuts.
How to Make This Recipe
Preheat oven to 350 Degrees F.
1. Add all the ingredients (except the preserves) in an electric mixer. Mix until thoroughly combined.
2. Using a small cookie scoop, scoop cookie dough, and place on parchment-lined cookie sheet. Score the top of the cookie dough with a fork. Bake for 15 minutes.
3. If using preserves, place scoops of dough on the cookie sheet, and make an indent in the center of the dough with your finger or thumb. Bake for 15 minutes. Once cool, fill the center of each cookie with 1 teaspoon jam.

Made these for the first time today and I'll make them again. They are tasty and my picky husband liked them also. Thanks for sharing your story about the dogs too, had no idea.

Kelly Methey says
These sound interesting. I will try them and see how they turn out!
I am so sorry about your pups! Are they totally fine? I have heard dogs can die from ingesting sweeteners. So glad you got them to the vet in time. $2,800.00 is a very expensive lesson!

Thanks, Kelly. Yes, it was quite stressful for a few days around here. So glad I took them in and that they were able to make a full recovery. As Scott said: "It's only money..."
