Cookie Dough Sandwich Monster Cookies

“If you find it all too painful, then move all books and papers away from the desk and write from the heart. It may be messy and need lots of rewriting, but at least for a while, you will get something on paper as your creativity breaks through…” — Karen O’Reilly 

These great big friendly giants aren’t called cookie monsters for nothing…

Cookie Monster Cookies - Half Peanut butter, Half Triple Chocolate Chip with Cookie Dough Frosting Filling

I’ll admit, when I set out to make these I had absolutely no idea what I wanted to make. I vaguely remember feeling torn between cookie dough chocolate cupcakes, (something rich and simply fudgy), or just a good old, soft and chewy peanut butter cookie…But realistically, I also knew that all I really wanted was just one extra large bowl of frosting. I kind of figured out that anything I did make would end up with frosting slathered all over it anyway…

Indecision can be so tough, but what an amazing blur Project Frosting turned out to be…

Cookie Monster Cookies - Half Peanut butter, Half Triple Chocolate Chip with Cookie Dough Frosting Filling

I mean, is it ever possible to go OTT on cookies?

The answer = apparently so No. Never. 

Although, the final product was supremely decadent to say the least…Surely this must be what the end of the world looks like; crumbling towers of monster cookies? Cuz I’m sooooooo up for that.

They came out huge (Looks like I still haven’t mastered the art of cookie scooping) – but nonetheless warm and soft and fudgy and generally fan-tabulous  ajdakfjdkfj.

Truthfully, I was actually pretty sad about having to actually bake these! – Particularly the chocolate half – the cocoa chip cookie dough was INSANE; we’re talking like, a-knee-deep-bowl-of-pure-chocolate- fudge here. It was ridiculously thick, chocolaty, incredibly rich and super buttery…the density of it was simply out of this world. I am still day dreaming about it. Frankly, it’s worth ‘making’ a batch of these cookies just so you can witness (and devour) the incredibleness of this chocolate cookie dough for yourself! They were the best soft + chewy triple chocolate chip cookies EVER! I can’t even begin to imagine how divine these would taste with a scoop or three of vanilla or cookie dough ice cream?! *Lovestruck* jsdsjfsjkef

…I truly am my own worst enemy.

The cookie dough filling was also one of the best ideas of this year so far. It was dreamily thick and perfectly whippy; a spreadable heaven.

Join the dark side and master the art of monster cookies!

Warning:  Cravings may persist.

Peanut butter cookie

  • ½ C softened salted butter
  • ½ C brown sugar
  • ¼ C white sugar
  • ½ C flour
  • ¾ C peanut butter
  • 1 tbsp vanilla
  • 1 egg
  • ½ tsp baking soda

Triple chocolate cocoa cookie

  • ½ C softened butter
  • ½ C white sugar
  • ½ C brown sugar
  • 1 C flour
  • ½ C + tbsp cocoa powder
  • 2 tbsp milk
  • 1 L egg
  • 1 tbsp vanilla
  • 1 x C white chocolate chunks.
  • 1 x C dark chocolate chips
  • ½ tsp baking soda.
  1. The method is the same for the each of the cookies, start by creaming together the softened butter (+ peanut butter), sugar, and vanilla. Add the egg last.
  2. In a separate bowl mix the dry ingredients together, before combining the wet with the dry, incorporating thoroughly. Add the milk. You should have 2 pretty thick cookie bowls of dough.
  3. Refrigerate the dough for 15 minutes before taking equal handfuls of each mix at a time, shaping into balls, and baking at 180*/350 * for 8-12 minutes.

Cookie dough frosting filler

  • ½ C butter
  • 3/4 C brown sugar
  • ½ C icing sugar
  • 1 C flour
  • Pinch of salt
  • 1 x tbsp vanilla
  • ¼ C heavy cream (more as needed).
  • 1 C chocolate chips.

Using a whisker/hand held stand mixer, cream the butter with the brown sugar first, before adding the icing sugar gradually. Add the flour, vanilla + salt next; the dough will be very thick + heavy until you add the cream. You might want to chill the dough for a bit, but otherwise, spread the dough between the cookies and sandwich away!

Cookie Monster Cookies - Half Peanut butter, Half Triple Chocolate Chip with Cookie Dough Frosting Filling

It’s hard to believe that I actually made these monsters way back in September (muaha they’ve been hidden from you for that long, sorrrrry) …does anyone else have this ridiculously chaotic routine of making stuff/editing photos/putting it away to do *later* before darting to and from all of the responsibilities + items that have been lingering on the to-do list for way longer than they should have been? It would be nice to know that I’m not alone on this guilty little procrastination ritual; I can’t even remember the last time where I didn’t feel like I was constantly having to play catch up with everything that needs to get done round here…

The past week has been crazy – mentally draining as well as plain out tiring. I only wish I had more time to blog and bake! I totally under estimated how hard 2nd year of university would be. I am drowning in new responsibilities, books that need to be read and essays that haven’t been done…Don’t even go all dissertation and scary careers stuff on me. #sonotready.

The top quote is something I (ironically) read whilst scanning a library book for essay content ideas, but it seriously helped me to push myself and just get on with everything as best as possible when everything was beginning to pile up this week, considering that all I seem to want to do is just bake, photographs, edit, eat, and repeat.

If anything, it feels refreshingly weird being able to write freely on here. I keep driving myself crazy by checking the little word counter down on the bottom left, paranoid that some kind of cookie monster policeman will shout at me if I go over the maximum count. And then of course, I snap out of essay mode; landing softly back into the delightful world of chocolate chip, buttery goodness as I remember just how much I love writing about food and how cookie monsters will someday save the world…Hopefully I’ve cleared enough down this week to get back into the swing of sugar, spice and all things nice next week…The baking addiction has been tortured for long enough.

Have a fabulous weekend guys! Tash xo


  • Kristi @ Inspiration Kitchen

    These ARE monster cookies! And, I love them! They look so crunchy and creamy all at the same time – it makes me want to take a bite!

    • Tashiana

      Yes they are definitely a strange yet amazing mix between the two! You can have a whole bunch – What do you say we trade these for some of that apple bundt cake? 😉

  • Imogen

    I literally can’t put into words what I feel about this recipe and the look of these. It’s just perfection! We’ve literally just got an oven and the first thing I wanted to bake was cookies… so yeah, this is definitely happening!! Also I totally understand how you’re feeling about second year, when I went into my second year this time last year I found the workload very challenging because freshers was just so chilled out. You kind of just have to focus on working hard but also making time for seeing your friends and social activities that will keep you sane!

    Imogen x

    • Tashiana

      Thanks Imogen! Its so nice to hear a little about your experience on the transition too. I really like what you’re saying, it’s all about balance and keeping yourself sane, right? Speaking of university, I am getting major travel envy from your France snaps! So glad to see how well you’ve settled in. It makes me want to go! <3

  • Louise@FitRadiance

    • Tashiana

    • Tashiana

      Thanks Stacey, I love how you understand what I’m saying! You too :)

  • Chineka @ Savor The Baking

      It’s too dangerous to imagine! They would taste divine.

  • Miranda | Miranda’s Notebook

    Wow! Those do look incredible! Next time I get a chocolate craving, I’ll have to have a go trying to whip some up 😉 Good luck at uni – I remember the second year as being pretty tough, but don’t worry, it’s worth balancing everything!

    • Tashiana

      Hey Miranda, thank for your those kind words! Yes yes yes do! Then we can both gush about how helplessly addicted we have both become to huge chunky sandwich cookies :)

  • Aisling

    Hnnngh, those look AMAZING! I know all too well about making massive cookies… I remember going through a stuffed cookie phase where I basically ONLY made stuffed cookies, but I would use the regular amount of cookie dough on either side of the stuffing, resulting in frankly ridiculously large cookies. But still delicious!

    Your photos are stunning!

    • Tashiana

      That sounds like a phase I would totally welcome! Sometimes you just can’t explain these craving obsessions! I love the sound of it haha! Thank you so much Aisling, that’s so sweet! x
