Sugar Free Peanut Butter Cup Cookies

These Halloween keto peanut butter cup cookies have to be the cutest Halloween cookie I’ve made. My kids flipped for these when I first made them and they demanded that we make them together ASAP! Luckily, this keto cookie recipe is very easy to make so it’s an easy one to get your kids involved with. Plus it only takes around around 30 minutes to make.

These keto cookies are for my peanut butter and chocolate fans. The cookie base is a keto peanut butter cookie, which surrounds a creamy, sugar-free peanut butter cup.

Decorate these keto halloween cookies as spiders or zombies. Both are fun options that everyone will enjoy – espcially if you are serving them at a Halloween party!

Keto Approved Peanut Butter Cups

You could make your own sugar-free peanut butter cups with this recipe or these keto peanut butter fat bombs, but if you don’t want to go through all of that hassle, then buy them! A couple of brands are making keto peanut butter cups to purchase but my favorite is ChocZero. Their keto peanut butter cups are sugar free and sugar alcohol free.

ChocZero has three different varieties of low carb peanut butter cups – dark chocolate, milk chocolate and white chocolate. For this halloween keto peanut butter cup cookie recipe, I used all three flavors. I used the sugar-free dark and milk chocolate peanut butter cups to make the spider cookies. I used the white chocolate keto peanut butter cups to make the zombie cookies.

Is Peanut Butter Keto?

Peanuts are one nut that you should eat in moderation on the keto diet as they contain a higher carb count compared to other nuts. One cup of peanut butter has 32 grams net carbs! There is no way you should be consuming 1 cup of peanut butter in a day on the keto diet. However, you can get away with using 1 cup of peanut butter in a recipe if the serving count is high.

These keto peanut butter cup cookies make around 15 cookies. That means that the peanut butter contributes to around 2 grams net carbs per cookie. This is just enough to keep these sugar-free halloween cookies low carb but still make them enjoyable and taste like peanut butter.

Substitutes for Peanut Butter

If you are still worried about consuming peanut butter on the keto diet, you can substitute the peanut butter for a more keto friendly nut butter like almond butter, cashew butter or macadamia nut butter.

I like to melt down sugar-free chocolate and put it in a piping bag. Then pipe out spider legs to make keto halloween spider cookies. You can even melt down sugar-free white chocolate and die it green to make zombie hair and a scary mouth. These keto halloween cookies are the cutest!

I add candy eyes to my low carb halloween cookies. These do have sugar in them but they hardly have any carbs in them if you just have a couple. Or you can pick them off and not eat them if you are totally avoiding sugar.

These cookies can be stored in an air-tight container at room temperature for several days. Or you can store these keto halloween cookies at room temperature uncovered for a couple days before they start to dry out.
