Chewy Halloween Monster Cookie Ingredients

For the Cookie Base

  • Unsalted Butter – Adds richness and moisture; ensure it’s at room temperature for easy creaming.

  • Vanilla Extract – Enhances flavor complexity; it’s optional but highly recommended for added depth.

For the Dry Ingredients

  • Rolled Oats – Adds a hearty texture; old-fashioned oats are ideal, while quick oats may change the crunch factor.

For the Festive Touch

  • Halloween-themed M&Ms – Infuses sweetness and color; reserve some for topping before baking for extra fun.

How to Make Chewy Halloween Monster Cookies

  1. Preheat Oven: Start by setting your oven to 350°F (175°C) to ensure it’s ready for baking these delightful treats.

  2. Prepare Baking Sheets: Line your baking sheets with parchment paper. This will prevent the cookies from sticking and make cleanup a breeze.

  3. Cream Butter & Sugar: In a stand mixer fitted with a paddle attachment, beat the softened butter and light brown sugar together until light and fluffy, about 2-3 minutes.

  4. Combine Wet Ingredients: Add the egg and creamy peanut butter to the mixture, mixing until fully combined, then incorporate the vanilla extract to enhance the flavor.

  5. Mix Dry Ingredients: Gradually add in the rolled oats, all-purpose flour, and baking soda, mixing until no dry spots remain. Be careful not to overmix for the best texture.

  6. Fold in M&Ms: Gently fold the Halloween-themed M&Ms into the dough, ensuring even distribution for that festive pop of color.

  7. Scoop & Shape: Using a scoop, portion out 1-inch balls of dough onto your prepared baking sheet, leaving enough space between them for spreading.

  8. Bake: Place the cookies in the oven and bake for around 15 minutes, or until the edges are set, and the centers appear slightly underbaked.

  9. Add Toppings: While the cookies are still warm, gently press candy corn and candy eyes into the tops so they stick beautifully.

  10. Cool: Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.

Optional: Drizzle with melted chocolate for an extra spooky touch!

Make Ahead Options

These Chewy Halloween Monster Cookies are perfect for busy home cooks who want to save time without sacrificing flavor! You can prepare the cookie dough up to 2 days in advance by mixing and refrigerating it in an airtight container. This not only saves time but also allows the flavors to meld beautifully. Additionally, you can freeze the dough in 1-inch balls for up to 3 months. When you’re ready to bake, simply take the frozen dough straight from the freezer and adjust the baking time by a couple of minutes. By taking these steps, your cookies will remain just as delightful, keeping that chewy texture and festive appeal with minimal effort!

How to Store and Freeze Chewy Halloween Monster Cookies

Room Temperature: Store cookies in an airtight container at room temperature for up to 7 days. Place a slice of bread in the container to help maintain their softness.

Fridge: If you’d like to prolong freshness, keep cookies in the fridge but consume them within 5 days to enjoy optimal texture. Bring them back to room temperature before serving.

Freezer: For longer storage, freeze cookies in an airtight container for up to 3 months. Thaw at room temperature, or warm them briefly in the microwave to regain their chewy goodness.

Cookie Dough Storage: You can also refrigerate the cookie dough for up to 2 days or freeze individual cookie dough balls and bake them straight from frozen—just add a couple of extra minutes to the baking time!

Tips for the Best Chewy Halloween Monster Cookies

  • Room Temperature Butter: Ensure your unsalted butter is at room temperature to achieve a light and fluffy texture when creaming with brown sugar.

  • Don’t Overbake: Pull the cookies out of the oven when the edges are set but the centers look slightly underbaked. This helps achieve that chewy, delicious texture.

  • Chill the Dough: For perfectly shaped cookies, chill the dough for at least 30 minutes before baking. This prevents them from spreading too much.

  • Gently Fold in Candies: When adding M&Ms, fold them gently into the dough to keep their shape and avoid breaking.

  • Experiment with Ingredients: Feel free to swap peanut butter for almond or sunflower seed butter for a different flavor in your Chewy Halloween Monster Cookies.

Chewy Halloween Monster Cookies Recipe FAQs

How do I choose the right peanut butter for the cookies?
When selecting peanut butter for your Chewy Halloween Monster Cookies, I recommend using a creamy natural peanut butter without added oils or sugars. This will ensure a smooth dough and enhance flavor. You can also opt for almond or sunflower seed butter if you have nut allergies or want a twist in flavor!

How should I store my Halloween Monster Cookies?
To keep your cookies fresh and delicious, store them in an airtight container at room temperature for up to 7 days. You can also add a slice of bread to the container to help maintain their softness. If you’re looking for long-term storage, pop them in the freezer where they’ll remain tasty for up to 3 months. Just remember to thaw them at room temperature before enjoying!

Can I freeze the Chewy Halloween Monster Cookie dough?
Absolutely! Freezing your cookie dough makes future baking a breeze. Shape the dough into 1-inch balls and place them on a baking sheet lined with parchment paper. Freeze until solid, then transfer the frozen balls into an airtight container or freezer bag. You can bake them straight from frozen, just add an extra minute or two to your baking time for perfect chewy cookies!

What should I do if my cookies turn out too hard?
If your Chewy Halloween Monster Cookies come out harder than expected, it’s likely due to overbaking. Always keep an eye on them towards the end of the baking time; they should come out of the oven with slightly underbaked centers. To rescue already baked cookies, you can place them in an airtight container with a slice of bread for a day, which helps to soften them again.

Are these cookies suitable for a vegan diet?
Yes, you can easily modify the Chewy Halloween Monster Cookies to be vegan! Simply substitute the regular egg with a flax egg (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water, let it sit for 5 minutes) and use a plant-based butter substitute. The rest of the ingredients can remain the same for a delicious treat everyone can enjoy!

What types of candies can I use for decoration?
The fun part of making these cookies is personalizing them! You can swap the Halloween-themed M&Ms with any favorite candies like chocolate chunks, pretzel pieces, or seasonal candies, depending on your taste. This flexibility lets you create a customized cookie that fits your festive spirit perfectly—The more the merrier!
