I made these as a sugar free substitute because my husband and I have been trying to cut back but still like a treat from time to time. These are awesome. We love them. I would recommend them to anyone.

Made these for guests at my daughter’s baby shower, and everyone said they were the best cookies they’ve ever had. One guest has been diabetic for over 25 years and even said they were her favorite.

Diabetic Peanut Butter Cookies
If you’re looking for diabetic dessert recipes, experiment with different types of sugar substitutes to find one that fits your diet plan.
For this recipe, I used Splenda and didn’t notice any aftertaste. As always, check with your doctor to determine which sugar substitute is best for your specific dietary needs.
Sugar Substitute for Baking
To lower the sugar content in these sugar free peanut butter cookies for diabetics even more, choose a natural peanut butter or one that’s lower in sugar than traditional brands.
Check out Stevia/Sugar Substitutes article for expert advice on selecting the ideal sugar substitute. Remember to consult your doctor for more tailored information.

Substitutions and Variations
Use natural peanut butter: Choose a variety with no added sugar for a less sweet, more traditional peanut butter flavor.
Add warmth with spices: Stir in a pinch of cinnamon along with the vanilla extract to give the cookies a cozy flavor boost.
Create a sweet-and-salty contrast: Sprinkle a little sea salt on top before baking for extra flavor and texture.

Step-by-Step Instructions
This section provides step-by-step photos and instructions to guide you through the recipe. For the complete printable version, scroll down to the recipe card below.

Step 1: In a mixing bowl, beat together the egg, sugar substitute, baking powder, and vanilla for about a minute. Add the peanut butter and water, then continue mixing until everything is well combined. The dough will be fairly thick and dry—just make sure the peanut butter is fully blended with the other ingredients.

Step 2: Using a cookie scoop, measure out a heaping teaspoon of batter for each cookie and place on a baking tray that has been sprayed with non-stick cooking spray or lined with parchment paper.

Step 3: Then using a fork, make indentations into each cookie. Spray the fork with cooking spray so it doesn't stick to the cookie. (Or dip the fork in a little of the sugar substitute.)

Step 4: Bake 8-10 minutes in a preheated 350°F oven until the cookies feel firm and are slightly browned. Transfer the cookies to a baking rack and cool.
Insider Tips from My Kitchen to Yours
✔️ DO mix the dough until the peanut butter is fully blended in with the other ingredients. The mixture comes together quickly and may look a little dry, but that’s normal.
❌ DO NOT skip spraying your fork with non-stick cooking spray or dipping the fork in the sugar substitute before making the criss-cross pattern. It prevents sticking since you won’t be using flour like in traditional peanut butter cookies.

Storing, Freezing, and Thawing Tips
Storing Tips: Store cookies in an airtight container at room temperature to prevent moisture and staleness. They’ll stay fresh for up to 3 weeks.
Freezing Tips: Place cooled cookies on a baking sheet and freeze for 1 hour. Once firm, wrap individually and store in an airtight container or freezer bag to keep them fresh.
Thawing Tips: When ready to eat, defrost the cookies in the refrigerator overnight before serving them at room temperature...yummy!
Recipe FAQ's

Yes, diabetics can enjoy sugar-free cookies, but it’s important to check the ingredients. Sugar-free doesn't always mean carbohydrate-free, so monitoring total carbs and ensuring the cookies fit within their dietary plan is key.
Yes, sugar-free peanut butter can be a good option for diabetics when consumed in moderation. It is low in carbohydrates and provides healthy fats, protein, and fiber, which can help with blood sugar control. However, it's important to check the label for added ingredients like hydrogenated oils or high sodium and choose a natural variety with minimal additives for the healthiest option.
The best peanut butter for diabetics is natural and unsweetened, made only with peanuts (and sometimes salt). Avoid brands with added sugar or oils, and choose options like Smucker’s Natural, Teddie, or Crazy Richard’s for a healthy, low-carb choice.
Yes, you can make peanut butter cookies without sugar by using a sugar substitute such as Splenda, Stevia, or Monk Fruit. These alternatives give you the same sweet flavor without the added sugar, making the cookies a great option for anyone watching their carb or sugar intake.

Cheryl says
I made these last night and they turned out really good. I used Skippy Natural Peanut Butter and Erythritol instead of Splenda. There was definitely a cooling effect from the erythritol, but that's normal and I'm used to it by now. I ended up making 16 (they were a bit large and I had some leftover dough that I threw out because my pan was full and I didn't want to cook another batch), but the rough estimates had them coming out at 2g net carbs. Definitely a keeper.
Maz says
Hi there,
I'm assuming you mean 350 degrees Fahrenheit? I use Celsius and that seems a bit hot.
Lois says
Yes, sorry for any confusion. I do mean Fahrenheit. Thank you!
Laura | Food Fun Family says
These look great! Thanks for sharing with the Delicious Dishes Recipe party!
Jamie Tomkins says
Those sound great - pinning this to try! 🙂 Thank you for sharing this with us at the #HomeMattersParty
Demi says
they look yummy and simple!!
JanVinyard says
Thanks for sharing this recipe - my husband's diabetic so I look forward to making them for him. Blessings, Janet
Yvonne says
I suppose if one is Diabetic then this recipe may suffice. It is certainly not healthy as Splenda is an artificial sugar substitute, complete with side effects.
Dee M says
I've made flourless peanut butter cookies before but not sugarless ones. Thanks for sharing this version at Merry Monday! 🙂
Lee MacArthur says
Isn't Splenda an artificial sweetner? That would be my only concern with this recipe. Otherwise it sounds quite good.
Just Plain Marie says
I'm sharing this in my Saturday Round Up email, Lois. It looks great, and it's awesome for anyone who is counting carbs. Only change I'd make is to use Xylitol (which, despite the weird name, is a natural sweetener) instead of Splenda.
