Why You’ll Love Chocolate Halloween Cookies

  • Fast: From mixing bowl to oven in no time!
  • Easy: No fancy techniques, just simple baking fun.
  • Giftable: Perfect for sharing with neighbors, teachers, or trick-or-treaters (if they’re lucky enough to get homemade!).
  • Crowd-pleasing: Who can resist chocolate and peanut butter together?

Ingredients

Alright, gather ’round, friends! Here’s what you’ll need for these chocolatey, peanut buttery delights. Most of these are probably already hanging out in your pantry, which makes this recipe even easier!

For the Cookies:

  • 1 cup white sugar: Just your good old granulated sugar to bring that perfect sweetness.
  • ⅔ cup butter, softened: Make sure it’s nice and soft, but not melted! This helps create a smooth, creamy base for your cookies.
  • ⅓ cup milk: Any milk will do, whether it’s whole, 2%, or even a dairy-free alternative if you’re experimenting!
  • 1 egg: The binder that holds all the goodness together.
  • 1½ teaspoons vanilla extract: A must-have for any good cookie, it really enhances the chocolate flavor.
  • 1½ cups all-purpose flour: The backbone of our cookies. Sifting isn’t strictly necessary but can make them a little lighter.
  • ½ cup cocoa powder: This is where that rich, dark chocolate flavor comes from. I love a good quality unsweetened cocoa powder for depth.
  • ½ teaspoon baking powder: Our leavening agent, giving them a lovely lift.
  • ¼ teaspoon salt: Don’t skip this! It balances the sweetness and really makes the chocolate sing.
  • 1 cup candy-coated peanut butter pieces (such as Reese’s Pieces®): The star of our Halloween show! These add incredible texture and that irresistible peanut butter flavor.

For the Frosting:

  • 3 tablespoons melted butter: Just a little melted butter makes for a super smooth, spreadable frosting.
  • 3 tablespoons cocoa powder: More chocolate, because why not?
  • 1 cup confectioners’ sugar: Also known as powdered sugar or icing sugar. This dissolves beautifully for a smooth frosting.
  • 2 tablespoons milk: Helps achieve the perfect consistency for spreading.
  • ½ teaspoon vanilla extract: Another dash to round out those delicious flavors.
  • ¼ cup candy-coated peanut butter pieces (such as Reese’s Pieces®), or to taste: For that final, festive flourish on top!

How to Make Chocolate Halloween Cookies

Let’s get baking! You’ll be amazed at how quickly these come together.

  1. First things first, preheat your oven to a cozy 350 degrees F (175 degrees C). You want it nice and warm for those cookies!
  2. Grab a big mixing bowl and your electric mixer. In it, you’re going to beat the white sugar and that softened ⅔ cup of butter together until they’re light, smooth, and creamy. This is the foundation of a fantastic cookie! Next, mix in the ⅓ cup of milk, the egg, and the 1½ teaspoons of vanilla extract. Scrape down the sides of the bowl to make sure everything gets fully incorporated.
  3. In a separate, medium-sized bowl, whisk together the flour, ½ cup cocoa powder, baking powder, and salt. Once that’s all combined, gradually add this dry mixture to your creamy butter mixture, stirring until the dough is just combined. Be careful not to overmix here; overmixing can lead to tough cookies, and we want them soft and tender! Finally, gently fold in that glorious 1 cup of candy-coated peanut butter pieces. Oh, the anticipation!
  4. Now for the fun part! Drop the dough onto your baking sheets. I like to use about 1 to 2 tablespoons per cookie. You can use a small cookie scoop for consistent sizes, or just a couple of spoons. Give them a little space because they will spread just a tad.
  5. Pop those beauties into your preheated oven and bake for 10 to 12 minutes. You’re looking for edges that are just crisping up. Every oven is a little different, so keep an eye on them.
  6. Once they’re baked to perfection, let them hang out on the baking sheets for about 2 to 3 minutes. This little rest helps them firm up before you move them. Then, carefully transfer them to wire racks to cool completely. Patience is key for that perfect frosting application!
  7. While your delicious cookies are chilling out, let’s make that dreamy frosting! In another bowl, grab your electric mixer again and beat the 3 tablespoons of melted butter and 3 tablespoons of cocoa powder together until they’re smooth and utterly creamy. Then, gradually beat in the confectioners’ sugar, 2 tablespoons of milk, and ½ teaspoon of vanilla extract until your frosting is wonderfully fluffy and smooth. If it’s too thick, add a tiny bit more milk, a half-teaspoon at a time. For another delicious chocolatey treat with peanut butter goodness, you might love our swirled brownie peanut butter cookies!
  8. Once your cookies are completely cool (seriously, don’t rush this, or your frosting will melt!), go ahead and frost them generously. Then, for the grand finale, sprinkle them with that remaining ¼ cup (or as much as your heart desires!) of candy-coated peanut butter pieces. Voila! Halloween cookie perfection!

Substitutions & Additions

The beauty of a classic cookie recipe is how easy it is to customize! Here are some ideas to make these Chocolate Halloween Cookies truly your own:

  • Candy Swap: Not a fan of peanut butter candies? No problem! You can easily swap them out for regular chocolate chips, M&M’s (try the Halloween colors!), chopped up candy bars, or even spooky sprinkles for a different look and taste.
  • Chocolate Boost: Want even more chocolate? Add a handful of mini chocolate chips along with the peanut butter candies to the cookie dough, or drizzle some melted white chocolate over the frosted cookies for a ghastly, web-like effect!
  • Spooky Sprinkles: Instead of, or in addition to, the extra candy pieces, decorate your frosted cookies with festive Halloween sprinkles. Think orange, black, purple, and green jimmies or fun ghost and bat shapes!
  • Cream Cheese Frosting: If you prefer a tangier frosting, a simple cream cheese frosting would be divine here. You could even swirl in a little orange food coloring for extra Halloween flair!
  • Pumpkin Spice Twist: For a fall-flavored kick, add ½ teaspoon of pumpkin pie spice to the dry ingredients in the cookie dough. It pairs wonderfully with chocolate and peanut butter!

Tips for Success

Even though these cookies are super easy, a few little pointers can make them absolutely perfect every time!

  • Softened Butter is Key: For both the cookies and the frosting, make sure your butter is truly softened, not melted, and not rock-hard. It should yield easily to a gentle press. This ensures smooth mixing and a perfect texture.
  • Don’t Overmix: Once you add the dry ingredients to the wet, mix just until combined. Overmixing develops the gluten in the flour, leading to tougher cookies. We want tender, chewy goodness! If you want to master the art of perfect cookies, paying attention to mixing is crucial.
  • Cool Completely Before Frosting: I know, I know, it’s hard to wait! But frosting warm cookies is a recipe for a melty, messy disaster. Let them get completely cool to the touch.
  • Room Temperature Ingredients for Frosting: While the frosting calls for melted butter, having your confectioners’ sugar and milk at room temperature can help create a smoother, lump-free frosting.
  • Even Sizing: For consistent baking and a pretty presentation, try to make your cookie dough drops roughly the same size. A cookie scoop is your best friend here!

How to Store Chocolate Halloween Cookies

So you’ve baked these beauties and perhaps managed to save a few from immediate consumption (good job!). Here’s how to keep them fresh:

Once your Chocolate Halloween Cookies are completely cooled and the frosting has set, store them in an airtight container at room temperature. They’ll stay fresh and delicious for 3-5 days. If you want to keep them longer, you can pop the airtight container in the fridge for up to a week. For longer storage, you can freeze them! Place the unfrosted cookies in a single layer in an airtight container, or separate layers with parchment paper, and freeze for up to 3 months. When ready to enjoy, thaw at room temperature and then frost as desired. You can even freeze the frosted cookies, though they might get a little condensation upon thawing, so it’s often best to freeze them plain if possible. If you’re looking for more delicious chocolatey treats that freeze well, our Reese’s Marshmallow Brownies are another fantastic option!

FAQs

Q: Can I use different chocolate candies?
A: Absolutely! Feel free to swap out the Reese’s Pieces for M&M’s, chocolate chips, or any other small, candy-coated chocolate you like. Just keep in mind it might change the flavor profile slightly if you omit the peanut butter candies entirely.

Q: My cookie dough seems too sticky. What should I do?
A: Sometimes the humidity or exact flour measurement can affect dough consistency. If your dough is too sticky to handle easily, add a tablespoon or two of extra flour until it reaches a manageable consistency. You can also chill the dough for 15-30 minutes before scooping.

Q: Can I make these ahead of time?
A: Yes! You can prepare the cookie dough a day or two in advance and store it in the refrigerator. Just bring it close to room temperature before scooping and baking. You can also bake the cookies ahead, store them unfrosted, and then frost them fresh on the day you plan to serve them.

Notes

Customize these cookies by swapping Reese’s Pieces for M&M’s, chocolate chips, or other candy. Boost chocolate with mini chips or white chocolate drizzle. Decorate with spooky sprinkles. For a tangier taste, use cream cheese frosting, or add a fall twist with ½ teaspoon of pumpkin pie spice. Ensure butter is softened, not melted, and avoid overmixing the dough for tender cookies. Always cool cookies completely before frosting to prevent melting. For best results, use room temperature ingredients for the frosting. Store cooled, frosted cookies in an airtight container at room temperature for 3-5 days, or in the fridge for up to a week. Unfrosted cookies can be frozen for up to 3 months; thaw before frosting.
