How to Make Halloween Spider Cookies

What’s not to love about peanut butter and chocolate?

This recipe for spider cookies is a classic peanut butter blossom cookie recipe. If you were making traditional blossom cookies, you’d add a chocolate kiss. But these spider cookies use peanut butter cups instead of chocolate kisses. 

Candy eyes, available at most craft stores (or even the grocery store this time of year), are set into the still-warm peanut butter cups. 

A little melted chocolate makes the legs, and you’ve got easy spider peanut butter cookies everyone will love!

Tips For Making Peanut Butter Cup Spider Cookies

After mixing your ingredients and making the peanut butter cookie dough, follow these tips so your spider cookies come out perfectly.

Weigh the dough

While you don’t have to do this, I like to weigh the dough for consistency in cookie size, and I use grams when weighing for a more precise measurement. Another reason I weigh this particular cookie is so there are enough peanut butter cups to cookies.

This kitchen scale is less than $15 and has over 90,000 5-star reviews.

Chill the cookie dough

With most cookie recipes, I find chilling the dough for half an hour to overnight results in a better cookie. You can either chill the dough before you roll them or after.

Unwrap all the peanut butter cups ahead of time

Unwrap the peanut butter cups from the foil ahead of time and keep them chilled. Once the cookies come out of the oven, you’ll need to work quickly to press each peanut butter cup into the warm cookies.  

You could enlist a little helper, provided you don’t lose half of the peanut butter cups in the process!

Under-bake the cookies slightly

I err on the side of slightly under-baked. You’ll want the cookies to be soft enough for the peanut butter cup to sink into the cookie. If they are over-baked, they will crumble. Wait about 3-5 minutes for the cookies to cool to prevent the peanut butter cups from melting too much.

Add the eyes while the chocolate is still warm

I add all the peanut butter cups first, and then go back and press the eyes into the warm chocolate. The chocolate acts like glue and helps adhere the eyes to the cookies.

Chill again

You don’t have to chill the cookies again, but I find it easier to add the spider legs after the cookies are completely cooled.

Can I Freeze Peanut Butter Spider Cookies?

Yes! You can freeze the dough after you’ve rolled it into balls, or you can freeze the finished spider cookies. 

If you’re planning on freezing the dough, skip the final roll in sugar. Freeze them flat on a cookie sheet. When completely frozen, transfer into a zip-lock bag. The dough should be used within three months. 

If you’re planning on freezing the finished cookies, wait until they are completely cool. Lay them flat on a cookie sheet and freeze until the chocolate is hard, then transfer to a zip-lock bag or other freezer safe container.

  • Pre-heat oven to 375 degrees F.
  • Using a stand mixer fitted with the paddle attachment, cream butter, brown sugar and 1/2 cup white sugar until blended, light and creamy, about 3 minutes.
  • Add egg, 1/2 cup peanut butter, milk and vanilla, and beat until well blended, 1-2 minutes.
  • In a medium sized bowl, mix flour, salt and baking soda. Slowly add flour mixture to butter and sugar, just until dough comes together. Don't over mix. For best results chill dough 30 minutes, or over-night.
  • Roll dough into walnut-sized balls, about 1 Tablespoon. Or weigh the dough and divide the measurement by 36 for uniform cookies. Cookie dough can also be frozen at this stage.
  • Roll each ball additional sugar, then place on cookie sheets lined with parchment or silpat.
  • Bake at 375 degrees F. for 10-12 minutes, until light golden brown, but still soft.
  • Remove from oven. Allow the cookies to cool about 3-5 minutes then place a peanut butter cup in the center of each cookie, pressing down slightly. While chocolate is still warm, attach candy eyes.
  • In a small bowl, melt chocolate morsels in the microwave at 30 second intervals, until chocolate is melted. Pour chocolate into a plastic sandwich bag. Snip off a tiny corner and drip 8 legs on each spider cookie. Chill until chocolate sets.

      I made these cookies and learned a few things along the way. Do NOT immediately put the peanut butter cups into the hot cookies from the oven as they literally start to melt-wait at least 5+ minutes to place the “cups” into the cookies. There’s still plenty of time for the chocolate to melt into the cookies and make placing the eyes much easier. The melted chocolate “legs” are a real mess and found Wilton black cookie icing makes much easier and thinner legs. The cookies are so cute, as well as delicious. Will make again before Halloween and use the things I have learned and will make for much nicer, less messy cookies.

      1. thanks for your tips. I found you really need to put the peanut butter cups fairly quickly before the cookies set up. Using a very thin tip helps with the legs. I prefer chocolate to black icing, but it sounds as though it worked well for you.

  1. These are so adorable and delicious looking! I am loving these and I am actually getting ready to bake cookies so maybe I will have to try this recipe as well 🙂 Thank you for sharing and pining next 🙂

  2. Wish I had read the comment about waiting about 5 minutes before put the peanut butter cup on. They melted and ran everywhere. They look like a mess. I will make them again but wait to put on the peanut butter cup and decorations.
