You don’t even know what a huge step this is for me. Normally my Halloween celebrations are limited to festive cocktails (like this Absolut Elyx Black Magic Martini and this Butterbeer Cocktail) and a big vat of spicy chili while I cuddle up waiting for trick-or-treaters with Hocus Pocus.

This year I thought I’d broaden my horizons and experiment with a festive dessert this Halloween.

I don’t know why, but when fall rolls around, peanut butter starts making a more regular appearance in my diet. I think it’s because it’s so rich and creamy, and it pairs so well with those freshly harvested apples.

Is there anything better than a freshly baked, chewy peanut butter cookie with a giant glass of milk?

The chewy cookie, the deep peanut butter taste… It’s one dreamy bite after another.

I mean, why not kick off the holiday baking season early, am I right?

The funny thing about baking is, you never really know how much using a high-quality flour matters until you start using one. That’s where my favorite Bob’s Red Mill Organic All Purpose Unbleached White Flour comes in!

Whether you are a novice or an advanced baker, you should be using this flour. It’s everything you need for anything that you bake from these cookies to bread, pizza crusts to cakes. It’s honestly the only flour brand I trust, because time and time again it makes all of my baked goods come out just right.

Take these cookies for example. Using the right flour REALLY matters to make sure you get just the right chewy texture.

I know some of you might be wondering if you can pull off the spiderweb icing on top and let me assure you right here and now, you CAN.

First, this royal icing is ridiculously simple to make.

Second, the decoration is deceivingly simple. You simply put a layer of white icing down first. Then you put a black dot in the center and make a black spiral working out from the center to the edge.

The magic happens when you drag a toothpick from the center dot to the outer edge! You do that all around the cookie and VOILA. Perfect spiderwebs for whatever spooky celebration you have coming up this weekend!

Have a SPOOK-tacular weekend!

This Recipe’s Must Haves

I use my stand mixer to pull together the dough for these cookies, but you can also use mixing bowls and your electric hand mixer if that’s all you have!

Bake these chewy cookies on your favorite half sheet baking pan with a silicone mat. 

To get the design on top, all you need are some of your favorite wooden toothpicks!

I use a large clear squeeze bottle for the icing and a little known fact is that these are an awesome substitute (and an easier one) for piping bags!

  10. Repeat this with the remaining cookies. Let set until the icing is set, approximately 1 hour.
