Step‑by‑Step Instructions for Monster Sandwich Cookies
Step 1: Frosting Preparation
In a medium bowl, use an electric mixer to beat 1 cup of softened unsalted butter and 4 cups of powdered sugar together on medium speed until the mixture becomes creamy and smooth, about 3-4 minutes. Then, add 2 teaspoons of vanilla extract and 2-3 tablespoons of milk, mixing until the frosting is light and fluffy, which should take another 2 minutes.
Step 2: Coloring the Frosting
Divide the fluffy frosting into separate bowls—one for each color you plan to use. Add a few drops of food coloring to each bowl, mixing vigorously until you achieve vibrant Halloween hues. You can have fun creating different shades; the mix should be well-blended and smooth to ensure an eye-catching finish on your Monster Sandwich Cookies.
Step 3: Cookie Pairing
Carefully sort the Chips Ahoy cookies into pairs based on their sizes. Make sure to flip one cookie in each pair upside down; this ensures that the flat sides face one another, ready to hold the fun frosting when assembled. This step sets the perfect foundation for transforming these cookies into delightful monster sandwiches.
Step 4: Assembling Cookies
Take one cookie from each pair and pipe or spread a generous layer of your colorful frosting onto the flat side. Ensure you have enough frosting to make the cookies stick together without spilling out too much; this adds to the monster fun. Then, place the second cookie, flat side down, gently pressing it on top of the frosting.
Step 5: Adding Candy Eyes
While the frosting is still soft, carefully press the candy eyes into the frosting on top of the assembled cookie. Arrange as many candy eyes as desired to create quirky monster faces. This step is where your creativity can truly shine, making each of the Monster Sandwich Cookies unique and even more playful.
Step 6: Setting
Once all the cookies are assembled, let them sit for about 10-15 minutes so the frosting can slightly set. If you need to store them for later, place the cookies in an airtight container to keep them fresh and prevent the frosting from getting too hard or sticky. Enjoy your charming creations when ready!

How to Store and Freeze Monster Sandwich Cookies
Room Temperature: Store your Monster Sandwich Cookies in an airtight container at room temperature for up to 3 days. This keeps them fresh while maintaining that delightful texture.
Fridge: If you’d like to extend their shelf life, place them in the fridge for up to a week. Just remember that refrigeration may slightly harden the frosting, so handle with care.
Freezer: For longer-term storage, freeze the cookies in an airtight container for up to 3 months. Layer parchment paper between cookie layers to prevent sticking.
Reheating: When ready to serve, simply let the cookies come to room temperature. If desired, you can pop them in the microwave for 10-15 seconds to soften the frosting.
Expert Tips for Monster Sandwich Cookies
-
Use Room Temperature Butter: Ensure your butter is softened to room temperature for a smooth, creamy frosting that spreads easily on your cookies.
-
Mind the Portions: Be generous but avoid overwhelming the cookies with frosting; too much can lead to messy assemblies. Aim for a delightful balance for your Monster Sandwich Cookies.
-
Frost with Precision: A zip-top bag with a snipped corner is perfect for piping the frosting neatly onto the cookies. It minimizes mess while helping control the amount applied.
-
Press Candy Eyes Firmly: Gently press the candy eyes into the frosting to guarantee they stick. If not pressed well, they may fall off during serving, risking the fun presentation.
-
Storage Savvy: Store your cookies in an airtight container at room temperature. If refrigerating, be cautious of humidity that can affect freshness and appearance.
Make Ahead Options
These Monster Sandwich Cookies are a fantastic treat to prepare in advance, making your Halloween celebrations stress-free! You can whip up the colorful buttercream frosting up to 3 days ahead of time; simply store it in an airtight container in the refrigerator to keep it fresh. For the best results, be sure to bring the frosting back to room temperature and give it a quick mix before assembling. You can also pair the Chips Ahoy cookies in advance, but it’s best to assemble them no more than 24 hours before serving to maintain their delightful crunch. When you’re ready to enjoy, just pipe on the frosting, add the candy eyes, and watch everyone delight in these fun and whimsical cookies—perfect for busy weeknights and festive gatherings!

Monster Sandwich Cookies Recipe FAQs
How do I choose the right cookies for my Monster Sandwich Cookies?
Absolutely! For the best results, opt for sturdy cookies like Chips Ahoy, which hold up well when sandwiched with frosting. If you’d like to make it more personalized, feel free to substitute with homemade cookies or other firm cookies that won’t crumble easily.
How should I store my Monster Sandwich Cookies?
I recommend storing your cookies in an airtight container at room temperature, where they stay fresh for up to 3 days. If you’re planning to keep them longer, you can refrigerate them for up to a week, but be careful as the frosting may harden slightly.
Can I freeze Monster Sandwich Cookies?
Certainly! To freeze your Monster Sandwich Cookies, first, ensure they’re completely assembled. Place them in an airtight container, adding layers of parchment paper between cookies to prevent sticking. They can be frozen for up to 3 months. When ready to enjoy, let them thaw at room temperature.
What should I do if my frosting is too runny?
Very good question! If your frosting turns out too runny, simply add more powdered sugar, a tablespoon at a time, until you achieve a thicker consistency. This will make it easier to pipe and spread without spilling over the edges of the cookies.
Are there any dietary considerations for these cookies?
Yes! If you’re making these Monster Sandwich Cookies for kids with allergies, consider substituting dairy ingredients with non-dairy alternatives and ensure that the cookies and decorations don’t contain any allergens like nuts or gluten. Always check labels, especially with candy eyes, as they can vary by brand.
How long will the candy eyes last on the cookies?
For the best presentation, it’s ideal to add candy eyes just before serving, as they can loosen over time. If you need to prepare ahead, store the cookies in an airtight container and add the candy eyes just before they’re served, ensuring they stay secure and lively!
