🛒 Ingredients
(Makes 18–20 sandwiches)
For the Cookie Sandwiches
- 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)
How to Make Monster Cookie Sandwiches
Step 1: Make the Frosting
In a medium bowl, beat the softened butter and powdered sugar together. Add the vanilla extract along with 2–3 tablespoons of milk or cream. Continue beating until the mixture is light and fluffy.
Step 2: Color the Frosting
Divide the frosting into separate bowls based on how many colors you want. Add food coloring to each bowl and mix until you achieve vibrant shades.
Step 3: Prepare Piping Bags (Optional)
Spoon the colored frosting into piping bags. If you don’t have piping tips, simply use bags without any tip or cut a small hole at one corner.
Step 4: Assemble the Cookie Sandwiches
Pair up cookies based on their size and shape. Flip one cookie from each pair upside down. Pipe or spread a generous dollop of frosting onto the flat side of one cookie. Top it 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 the cookies so they peek out like monster eyes. Get creative — feel free to use one eye, two eyes, three eyes, or more!
Step 6: Let Set & Store
Allow the frosting to firm up before serving. If you’re not serving immediately, store your cookie sandwiches in an airtight container in the fridge for 1–2 days.
⚠️ Note: In humid climates, be sure to keep an eye on your frosting’s consistency!

Common Mistakes to Avoid
When making Monster Cookie Sandwiches, it’s easy to run into some common pitfalls that can affect the final product. Here are a few mistakes to watch for:
-
Skipping the Butter Softening: Not softening the butter before mixing can lead to a dense frosting. Always allow your butter to reach room temperature for a creamy texture.
-
Overmixing the Frosting: Mixing the frosting too long can make it too airy and difficult to spread. Beat until just combined and fluffy for best results.
-
Ignoring Food Coloring Quality: Using low-quality food coloring can result in faded colors. Opt for gel or concentrated colors for vibrant, Halloween-ready shades.
-
Not Pairing Cookies Properly: Choosing mismatched cookie sizes may cause uneven sandwiches. Take time to find pairs that fit well together.
-
Forgetting to Let Frosting Set: Skipping the setting time for frosting can make sandwiches messy when serving. Allow them to firm up before enjoying.
