Step‑by‑Step Instructions for Monster Sandwich Cookies
Step 1: Frosting Preparation
In a medium mixing bowl, beat 1 cup of softened unsalted butter with 4 cups of powdered sugar using an electric mixer on medium speed for about 2-3 minutes, until light and fluffy. Gradually add 2-4 tablespoons of milk and 1 teaspoon of vanilla extract, mixing until the frosting reaches a smooth and spreadable consistency.
Step 2: Coloring the Frosting
Divide the fluffy frosting into separate bowls, depending on how many colors you want to create. Add a few drops of food coloring to each bowl, and mix until you achieve vibrant shades that excite your imagination for these Monster Sandwich Cookies. Aim for colorful and festive hues that will make your cookies pop!
Step 3: Cookie Pairing
Take a box of Chips Ahoy cookies and carefully match them into pairs based on size and shape. Flip one cookie in each pair upside down, allowing for a flat side to spread frosting on. Align the cookies so they will create delightful sandwiches filled with that sweet, colorful frosting.
Step 4: Assemble Sandwiches
Once you have your cookie pairs ready, take the flipped cookies and pipe or spread a generous layer of your vibrant frosting on the flat side of one cookie. Gently press the matching cookie on top to form a lovely sandwich, securing your delicious frosting filling inside. The Monster Sandwich Cookies are starting to come together beautifully!
Step 5: Decorating
While the frosting is still soft, press candy eyes into the frosting of each cookie sandwich. Get creative with the placement; mix and match to make quirky monster faces. This step is fun for kids and allows everyone to unleash their inner artist, making your Monster Sandwich Cookies even more festive!
Step 6: Setting
After decorating, let the Monster Sandwich Cookies sit at room temperature for about 10-15 minutes to allow the frosting to set slightly. If you’re not enjoying them right away, store the cookies in an airtight container at room temperature to keep them fresh, and enjoy your delightful creations later!

Make Ahead Options
These Monster Sandwich Cookies are perfect for meal prep, allowing you to create a festive treat without the last-minute rush! You can prepare the frosting up to 48 hours in advance; just store it in an airtight container in the refrigerator to maintain its freshness and prevent drying out. The cookie pairs can also be pre-matched and stored in a separate container, ensuring they stay crisp. When you’re ready to enjoy, simply spread the frosting on the cookies, decorate with candy eyes, and let them set for about 10-15 minutes before serving. This approach ensures you’ll have these adorable no-bake treats ready for any Halloween celebration with minimal effort!
How to Store and Freeze Monster Sandwich Cookies
Room Temperature: Keep the cookies in an airtight container for up to 2 days to maintain freshness, perfect for easy Halloween treats.
Fridge: For extended freshness, you can refrigerate the cookies for up to 5 days; however, note that the frosting may become a bit soft when taken out.
Freezer: If you want to make them ahead, freeze the assembled cookies in a single layer for up to 3 months. Wrap each sandwich in plastic wrap before transferring to a freezer-safe bag.
