Key ingredients & substitutions

  • Keto flours – The combination of almond flour and coconut flour makes a delicious shortbread cookie. The crumb and texture are delicate and the flavor is very similar to a traditional cookie. And don’t worry, these do not taste like coconut!
  • Butter – Gives these keto Halloween cookies a rich, buttery flavor.
  • Sweetener – Any sugar-free sweetener that measures cup for cup with sugar will work in this recipe. Consider using a monkfruit erythritol blend. If using allulose, you may need to add a little bit more.
  • Keto chocolate – It’s easiest to use sugar free chocolate chips as they melt easily; however, keto nutella substitutes can be used as well.

  • Coconut flour
  • Salt
2
Cream butter and sweetener

In a separate bowl, cream together butter, sugar free sweetener and vanilla extract.

Tip Refrigerating the dough always for the flavors to come together and it makes it easier to punch out pumpkin shapes.

Pumpkins & jack o' lanterns

Remove cookie dough from the refrigerator and punch out pumpkin shapes using a pumpkin cookie cutter. Place each pumpkin onto a parchment lined baking tray. Using a knife, cut out a jack o lantern face in half of the cookies. Refrigerate again for 15-20 minutes.

Tip If cookies start to get soft, making it harder to cut out the pumpkin shapes, return dough to the refrigerator to reharden. Refrigerating the dough the second time prevents the cookies from spreading too much during baking.
6
Bake

Bake at 350 degrees for 6-7 minutes or until edges start to turn golden brown. Remove from the oven and let them cool completely. DO NOT try to handle the cookies before you have let them cool completely on the baking tray or else they will crumble and break. They are very soft after baking but will harden once they cool.

Tip If your keto cookies did spread, use a knife to reform the edges of the cookie while they are still warm.
7
Chocolate face

In a small bowl, add chocolate chips and coconut oil. Melt by microwaving at 30 second intervals, stirring in between. Spread melted chocolate on the pumpkin cookie that is whole (no face) and place the jack o lantern cookie on top. Repeat with remaining cookies.

Frequently Asked Questions

Why did my cookies spread?

Your keto cookies may have spread because your cookie dough was too soft and warm when you put the cookies in the oven to bake. Don't skip the refrigeration step because it helps to firm the cookies up before baking in order to keep their shape.

Can I make smaller or bigger cookies?

Yes, you can make different sized Jack O' Lanterns. Just use smaller or larger cookie cutters. Macros per cookie will vary based on size.

Why did my cookies crumble after I picked them up?

It sounds like you didn't let the cookies cool completely before handling them. I have made this recipe many times and know that once they have cooled for several minutes, you can pick them up and handle them without crumbling.

    These turned out really cute and the chocolate center was perfect. I noticed my dough was a bit sticky after mixing — is that normal or did I maybe soften the butter too much?

      As long as your cookies turned out good, I don't see the sticky dough as a problem. You could also add more keto flour if you feel like the cookies spread too much during baking.
