🛒 Ingredients

(Makes 18–20 sandwiches)

For the Cookies

36–40 Chips Ahoy cookies (for 18–20 sandwich pairs)

For the Frosting

1 cup (2 sticks) unsalted butter, softened
4 cups powdered sugar
2–3 tablespoons milk or heavy cream
2 teaspoons vanilla extract
Food coloring (Halloween colors like orange, green, purple, etc.)
Candy eyes (variety of sizes if desired)

Step 1: Make the Frosting

In a medium bowl, beat the softened butter and powdered sugar together until well combined. Add vanilla extract along with 2–3 tablespoons of milk or cream. Continue beating until the mixture becomes light and fluffy.

Step 2: Color the Frosting

Divide your frosting into separate bowls based on how many colors you’d like. Add food coloring to each bowl, mixing until you achieve vibrant hues that capture the spirit of Halloween.

Step 3: Prepare Piping Bags (Optional)

Spoon your colored frosting into piping bags. If you don’t have piping bags, you can simply use a zip-top bag with one corner snipped off.

Pair up cookies based on their size and shape. Flip one cookie upside down from each pair. Pipe or spread a generous dollop of frosting onto the flat side of this cookie. Top with the second cookie to create a sandwich.

Step 5: Add Candy Eyes

While the frosting is still soft, gently press candy eyes into the sides of each sandwich so they peek out like monster eyes. Feel free to be creative with how many eyes you add!

Step 6: Let Set & Store

Allow your assembled sandwiches to sit until the frosting firms up slightly. If you’re not serving them right away, store them in an airtight container in the fridge for up to 1–2 days. Enjoy your delightful Monster Cookie Sandwiches!

To make sure your Monster Cookie Sandwiches turn out perfectly every time, follow these helpful tips.

Bold Butter: Ensure your butter is softened before mixing. This helps create a smooth and fluffy frosting that spreads easily.
Bold Color Mixing: When adding food coloring, start with a small amount and gradually increase until you achieve your desired shade. This prevents over-coloring and keeps the frosting vibrant.
Bold Cookie Pairing: Choose cookies of similar sizes for even sandwiches. This not only looks better but also ensures balanced bites.
Bold Frosting Application: Use a piping bag to apply frosting for cleaner edges and more control over the amount used, making your sandwiches visually appealing.

Pair your Monster Cookie Sandwiches with fun side dishes that complement their sweetness. Here are some great options:

Fruit Skewers: Colorful fruit skewers made with seasonal fruits add freshness and balance to the sweet treats.
Veggie Platter: A crunchy veggie platter with dips provides a savory contrast to the sweetness of the sandwiches.
Popcorn Mix: Create a Halloween-themed popcorn mix with candy corn, nuts, and chocolate for an exciting snack.
Cheese Cubes: Offering cheese cubes adds a salty element that pairs well with sweet cookies, making for diverse flavor experiences.
Mini Cupcakes: Serve bite-sized cupcakes topped with colorful frosting as an additional sweet treat that matches the festive theme.
Trail Mix: A homemade trail mix featuring nuts, seeds, dried fruits, and chocolate bits creates a crunchy side that complements the softness of cookie sandwiches.

Common Mistakes to Avoid

Making Monster Cookie Sandwiches can be a fun experience, but there are common pitfalls to watch out for.

Not Softening the Butter: Using cold butter can make it difficult to achieve a smooth and fluffy frosting. Always soften the butter at room temperature before mixing.
Overmixing the Frosting: While you want a light and fluffy texture, overmixing can lead to a runny consistency. Beat just until combined for the best results.
Ignoring Cookie Size: Pairing cookies that are too different in size can lead to uneven sandwiches. Always match similar-sized cookies for balanced sandwiches.
Not Letting Frosting Set: If you serve right away, the frosting may not hold up well. Allow it to set in the fridge for a little while before serving for better results.
Using Too Much Food Coloring: Adding too much coloring can alter the frosting’s texture. Start with a small amount and gradually add more until you achieve your desired color.
