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 – especially if you are serving them at a Halloween party!
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.
