I'm just going to keep it short here because November seems to be kicking me in the butt a little - there is a pre-christmas rush at the studio, a zillion things on, more foster cats, and the holidays to plan for. Maybe it's the light - it gets dark here around 4.30 now, which means I can't really shoot past 3, so maybe the days have felt a little more stressful because I feel the time pressure. It's so, so busy, but the best kind of busy. The sort of busy where you go to sleep exhausted. I have managed to keep somewhat of a routine, and getting up at 6am to have some me time as the sun rises seems to be helping a lot. I can chill out for a little bit with just me awake, and prepare myself a little for the day ahead. I have lots of exciting things coming up here so watch this space!
These cookies are ridiculous. Most things I make with Jill usually turn out to be ridiculous. We made these a couple of weeks back but didn't quite get things right. They were delicious, but ugly AF, so we tweaked them a little last week and I think we have nailed it. We used the TKO recipe from the Bouchon Bakery book, which yields super rich, not too sweet, thin crispy cookies, and we sandwiched these with a tahini marshmallow. Tahini marshmallow is every bit as magical as it sounds, and you need it in your life. It's literally just tahini folded into my regular marshmallow recipe, but it somehow cuts the sweetness of the marshies, while perfectly complimenting the chocolate. These are great. You should make them.
Jill and I actually shot these separately because we lost light on the day we made them - but pop over to her site and have a look, because we ended up with some very similar images! Great minds 😉
A few wee notes:
- Make the tahini marshmallow first - this will give it time to cure while you do the cookies.
- I have included in the marshmallow instructions to whip until you see strands forming round the edges of the bowl - this may seem like you have taken it too far and it will be quite stiff, but the structure is needed for when the tahini is added.
- We used Honey for the marshmallow because it compliments the tahini very nicely, but corn syrup or glucose will work too!
- If you don't like tahini - just leave it out.
- The dough for the cookies can be made the night before if you would like - sometimes it takes more than an hour for it to really firm up.

A note on salt and oven temperature
It is important to note the type of salt that is called for in a recipe. I use Diamond Crystal salt throughout my recipes - if you use a different sort of kosher salt or regular table salt you will need to adjust accordingly as some salt is 'saltier' than others. Morton's salt is twice as salty, so you will need half the quantity. Same goes for a regular table salt. I am working to get gram measurements throughout my recipes for salt but still getting there.
All oven temperatures are conventional unless otherwise stated. If you are baking on fan / convection, you will need to adjust the temperature. An oven thermometer is a great investment to ensure that your oven is the correct temperature.

Why is this recipe in grams?
I post my recipes in grams as it is the most accurate way to bake. Cups are not only inaccurate but they vary in volume worldwide. There is no way for me to provide one cup measure that works for everyone. However, posting in weight fixes this issue. If you would like the recipe in cups you are welcome to convert it yourself via google, but please do not ask me to do it for you as I am not comfortable providing a recipe using a method that I have not tested. Baking with a scale is easy, accurate, and also makes cleanup super simple. Here is the scale that I use if you would like a recommendation! Here's to accurate baking! If you would like to scale this recipe or convert for another pan size, use my calculator!

Description
Chocolate Sandwich Cookies with Tahini Marshmallow
Ingredients
Tahini Marshmallow
- 21g (0.75oz, or 3 packets) gelatine
- 114g (4 oz, 114ml) cold water
- 155g Liquid honey
- 114g (4oz, 114ml) water
- 400g (14oz) sugar
- 1 Tbsp vanilla paste, or the seeds of 1 vanilla bean
- ¾ cup (170g) tahini
Marshmallow "Dust"
- ½ cup (65g) powdered sugar
- ½ cup (65g) Corn Starch
Chocolate Cookies
- 389g All-purpose flour
- 131g dutch-process cocoa
- 2.4g (heaped half teaspoon) baking soda
- 345g (3 sticks) unsalted butter, at room temperature
- 6 g (2 tsp) salt
- 242g sugar
- 1 tsp vanilla
To finish
- 100g milk or dark chocolate, melted (optional)
Instructions
TAHINI MARSHMALLOW
- Grease a 12" x 16" baking sheet (half sheet), or jelly roll pan with neutral oil or butter. Combine the powdered sugar and corn starch and set aside. This is your "Marshmallow dust".
- In the bowl of a stand mixer fitted with the whisk attachment, combine the cold water and gelatine. Mix well with a fork, and leave to bloom while you prepare the sugar syrup.
- In a medium pot, combine the water, honey, vanilla, and sugar. Heat over medium to high heat, stirring occasionally. Heat until the syrup reaches 240˚f / 120˚c, then remove from the heat and leave to cool to 210˚f / 100˚c.
- Turn the mixer on to medium, and mix for a few seconds to help break up the bloomed gelatin. With the mixer running, VERY carefully pour the hot sugar syrup into the mixer. Turn the speed up to high, and whip for 7-10 minutes, until the marshmallow has doubled in volume, has turned white, and holds somewhat of a peak when you stop the mixer and lift out the whisk. You want to see little strands starting to form around the whisk attachment as it whips - this may seem like you have taken it too far, but you need the structure for when you add the tahini.
- Add the tahini, and fold in well with a spatula.
- Working quickly, scrape the marshmallow into the prepared tin using a lightly oiled rubber spatula. Smooth the surface using an oiled offset spatula, or back of a spoon. Use wet fingers to help the smoothing process if needed. Dust liberally with the marshmallow dust. Allow to cure for 3-4 hours.
- Carefully turn out onto a board, and dust the entire surface with the powdered sugar and corn starch mix. Using a 2 ½ inch cutter dusted with marshmallow dust, cut circles out of the marshmallow. Set aside on a plate, dusting with extra marshmallow dust if needed.
CHOCOLATE COOKIES
- In a medium bowl, sift together the flour, cocoa, and baking soda.
- In the bowl of a stand mixer fitted with the paddle attachment, beat the butter on high until smooth and creamy, 2-3 minutes. Add the salt, and mix for another 30 seconds, then add the sugar and vanilla and mix for a further 3-5 minutes, until pale and fluffy.
- With the mixer on low (be careful not to puff flour everywhere!), add half of the dry ingredients, and mix until just combined. Add the second half, and mix until incorporated. Turn the mixture out onto a piece of plastic wrap, and bring together to form a rectangle. Wrap tightly and place in the fridge for at least an hour, or until firm.
- Preheat the oven to 325˚f / 165˚c, and place oven racks in the upper and lower thirds of the oven. Line two baking sheets with parchment paper. Place the rectangle of cookie dough on a sheet of parchment paper, and top with a second piece. Hit it a couple of times with your rolling pin to help flatten. Roll out the dough to approximately ⅛" thickness, then transfer to a baking sheet or board, still between the parchment paper, and place in the fridge for about 10 minutes to help it firm up.
- Remove the dough from the fridge and peel off the top layer of parchment. Using a 2 ½ inch cutter, cut circles from the dough, and place on the lined baking sheets, leaving about ½ an inch between. Re-roll scraps and cut more cookies if desired. Bake for 15-17 minutes, rotating once during cooking, until the cookies have firmed. Remove from the oven, allow to cool for 10 minutes on the baking sheet, then transfer to a wire rack to cool completely.
ASSEMBLY
- Pair up the cookies into pairs of equal size. Place a marshmallow circle between each pair of cookies. Secure with a little melted chocolate if needed. Drizzle the finished cookies with melted chocolate. Allow the chocolate to set in the fridge if needed. Store in an airtight container.
