We all knows how nicely crispy and chewy cookies normally are. In this recipe, they are are complemented by that soft and fluffy marshmallow center. This creates a wonderful and unique contrast that is certainly enjoyable. It reminds me of something like a whoopie pie. For those who have eaten Lotte chocolate pies, it is something similar in concept as well except without the final chocolate coating around the shells of the cookies. If you want, you can definitely feel free to coat it with chocolate!
For the flavour, there is a nice contrast created by this recipe too.
There is a relatively large amount of cocoa powder added with a low amount of sugar. This is to ensure that the cookie is still nicely edible and sweetened but it maintains that nice bitterness of the chocolate. You can definitely feel free to add about 1/4 cup more of granulated white sugar if you are not a big fan of the bitterness of cocoa powder!
There comes the contrast. Between the two bittersweet cocoa cookies, they sandwich a sweet melted marshmallow. This makes it such that there will not be any overlapping of flavours and you can tell that here there are two distinct components.
On top of which, you can spice up these cookies. Not literally by adding spice of course!
You can add things such as chocolate chips or nuts ( which I did ), up to an amount of about 3/4 cup. These will add a third dimension to these Marshmallow Sandwich Cookies. It will allow them to have that pleasant and audible crunch as you bite into them!
One of the other things I added on top of Chocolate Chips is my Funfetti or Confetti or Colour Rice ( depending on which country you live in ). These add a pretty visual appeal to these cookies with their vibrant colours!
Ultimately, it is pretty much up to you!
For the method, it is not too difficult. As long as you have an oven, you are good to go.
