Purple Monster Cookie Sandwiches: 1 Batch of Pure Joy

Is there anything more fun than biting into a bright purple cookie sandwich stuffed with creamy frosting and loaded with chocolate chips and M&M’s? I first made these Purple Monster Cookie Sandwiches for my niece’s birthday party years ago, and now they’re my go-to treat whenever we need a little extra joy. The kids go wild for the vibrant color, and let’s be honest – the adults sneak seconds too! What I love most is how simple they are to whip up while still looking impressively festive. Just wait until you see the smiles when you bring out a platter of these cheerful purple treats at your next gathering!

Why You’ll Love Purple Monster Cookie Sandwiches

Trust me, these aren’t your average cookies – they’re pure edible happiness! Here’s why everyone falls for them:

• Instant party mood: That vibrant purple color just makes people smile before they even take a bite. I’ve seen grumpy teenagers light up when these hit the dessert table!
• So easy a kid could make them (and mine do!) – the dough comes together in one bowl with simple ingredients you probably have right now
• Endlessly customizable: Swap out the M&M’s for sprinkles, use different food coloring for holidays, or try peanut butter frosting instead of vanilla
• Perfect make-ahead treat: They stay soft for days, so you can bake them when you have time and assemble later

Honestly? The hardest part is not eating all the dough before it hits the oven!

Ingredients for Purple Monster Cookie Sandwiches

Now let’s talk ingredients – and here’s my golden rule: quality matters, but don’t stress about perfection. I’ve made these with whatever I had in the pantry more times than I can count, and they always turn out delicious. Here’s exactly what you’ll need:

• 1 cup (2 sticks) butter, softened – Leave it out for 30-60 minutes until your finger leaves a dent. Microwave softening is a no-no – it changes the texture!
• 1 cup granulated sugar + 1 cup packed brown sugar – The brown sugar should feel like wet sand when packed
• 2 large eggs – Room temperature blends better, but cold works in a pinch
• 1 teaspoon vanilla extract – The good stuff makes a difference here
• 3 cups all-purpose flour – Fluff it before measuring or you’ll get dense cookies
• 1 teaspoon baking soda + 1/2 teaspoon salt – Yes, both! They’re flavor boosters
• 1 cup chocolate chips + 1 cup M&M’s – I use semi-sweet chips, but milk chocolate works too
• Purple food coloring – Gel gives richer color than liquid
• 1/2 cup frosting for filling – Store-bought or homemade, any flavor you love

See? Nothing fancy – just good, simple ingredients ready to transform into something magical!

Equipment You’ll Need

Don’t worry – you don’t need fancy gadgets for these cookie sandwiches! Here’s what I always grab from my kitchen:

• Large mixing bowl – Big enough for all that dough goodness
• Electric mixer or sturdy wooden spoon – Your arm will thank you for the mixer
• Baking sheets – Two standard-sized pans work perfectly
• Silicone spatula – For scraping every last bit of purple dough
• Cookie scoop or spoons – Makes uniform cookies (but irregular ones taste just as good!)
• Cooling rack – Essential for preventing soggy bottoms

That’s it! Now let’s get mixing.

How to Make Purple Monster Cookie Sandwiches

Okay, let’s get to the fun part! Making these vibrant cookie sandwiches is easier than you think – I’ll walk you through every step like I’m right there in the kitchen with you. Just follow along, and in less than 30 minutes, you’ll have the most cheerful purple cookies ready to sandwich with creamy frosting!

Preparing the Cookie Dough

First things first – preheat your oven to 350°F (175°C). Now, let’s make that dough! Grab your softened butter and sugars and beat them together until they’re light and fluffy. This takes about 2 minutes with a mixer, or 3-4 minutes of vigorous stirring if you’re using a spoon. Add the eggs one at a time, mixing well after each, then splash in that vanilla. Here’s my trick: scrape down the bowl sides halfway through – it makes all the difference!

In another bowl, whisk together the flour, baking soda, and salt. Gradually add this to the wet ingredients, mixing just until combined. No overmixing here – we want tender cookies, not hockey pucks!

Adding Color and Mix-Ins

Now for the magic! Start with about 10 drops of purple food coloring (more if using liquid, less if using gel). Fold it in gently – you’ll see streaks at first, but keep mixing until you get that perfect monster purple. Taste the rainbow? No, we’re making the rainbow! When the color’s right, gently fold in the chocolate chips and M&M’s. The dough will be thick and glorious – resist eating it all by the spoonful (I know, it’s hard)!

Baking and Assembling

Scoop tablespoon-sized balls of dough onto your baking sheets, leaving about 2 inches between them – these babies spread! Bake for 10-12 minutes until the edges just start to golden. They’ll look underdone in the center – that’s perfect! Let them cool on the pan for 5 minutes (they’ll keep cooking), then transfer to a rack to cool completely.

Once cooled, spread about 1 tablespoon of frosting on the flat side of one cookie and sandwich with another. Press gently – you want that frosting to peek out just a little. Voila! Purple monster magic in cookie form!

Tips for Perfect Purple Monster Cookie Sandwiches

After making dozens (okay, maybe hundreds) of these cookie sandwiches, I’ve picked up some foolproof tricks to guarantee monster success every time:

• Oven thermometer check: My oven runs hot, so I always verify 350°F with a thermometer – burnt purple cookies are just sad!
• Color gradually: Add food coloring a few drops at a time – you can always deepen the purple but can’t undo it.
• Cool completely: Warm cookies melt the frosting into a messy (but delicious) puddle.
• Airtight storage: Keep them in a container with wax paper between layers to maintain that perfect texture.

Oh, and one bonus tip? Make extra – these disappear faster than you’d think!

Variations for Purple Monster Cookie Sandwiches

The beauty of these cookies? You can reinvent them a dozen ways! Try swapping the vanilla frosting for cream cheese or peanut butter filling – my kids go crazy for the PB-chocolate combo. Feeling festive? Use green food coloring for Halloween or pastel hues for Easter. And the mix-ins? White chocolate chips with dried cranberries make a gorgeous holiday version, while swapping M&M’s for rainbow sprinkles turns them into birthday magic. Honestly, once you master the base recipe, the possibilities are endless!

Serving and Storing Purple Monster Cookie Sandwiches

These cookie sandwiches disappear fast, but if you somehow have leftovers (miracle worker!), here’s how to keep them perfect. Store them in an airtight container at room temperature with wax paper between layers – they’ll stay fresh and soft for up to 4 days. Want to prep ahead? The unfilled cookies freeze beautifully for a month in freezer bags – just thaw and frost when you’re ready to serve. Pro tip: Bring them to room temperature before serving so the frosting gets that perfect creamy texture again!

Nutritional Information for Purple Monster Cookie Sandwiches

Let’s be real – we’re not eating these for their health benefits! But since you asked, here’s the scoop: Each cookie sandwich has about 320 calories, with the usual cookie suspects (sugar, butter, flour). These numbers can vary based on your specific ingredients and how generous you are with that frosting. Store-bought frosting bumps up the sugar, while homemade might change the fat content. My advice? Enjoy every purple bite guilt-free – life’s too short to skip the fun desserts!

Frequently Asked Questions

Over the years, I’ve gotten the same excited questions about these purple beauties. Here are the answers I always give my friends and family!

Can I use gel food coloring instead of liquid?

Absolutely! Gel food coloring actually gives a much more vibrant purple with less liquid added to your dough. Start with just a tiny dab (like the size of a pea) and mix it in – you can always add more if you want a deeper color.

How long do the cookie sandwiches stay fresh?

Stored properly in an airtight container, they’ll stay soft and delicious for 3-4 days at room temperature. After that, they’re still edible but lose some of that perfect texture. The unfilled cookies actually freeze great for up to a month!

Can I make these without the food coloring?

Of course! They’ll taste just as amazing – just not as wildly purple. The M&M’s still give them plenty of colorful fun. I sometimes make a “naked” version with rainbow sprinkles instead when I’m out of food coloring.

What’s the best way to get evenly sized cookies?

I swear by my cookie scoop – it’s a game changer! But if you don’t have one, just use two spoons and eyeball about 1 tablespoon of dough per cookie. Imperfect ones taste just as good (maybe better because they have character!).
