This healthy s’mores double chocolate sharer cookie is the perfect dessert to enjoy with the marshmallow lover in your life.

The giant soft centred cookie is best enjoyed when the cookie dough is still warm and soft, the chocolate is melting and the marshmallows are gooey. The slightly bitter dark chocolate works perfectly with the sweetness of the white chocolate and marshmallows making this a truly delicious, indulgent feeling dessert.

I had the classic skillet cookie in mind when creating this and, as we are heading into s’mores season, topping it with marshmallows to create a showstopping dessert seemed like the obvious choice. I did think about using my Chocolate Chunk Cookie recipe or a similar double chocolate cookie dough as the base for this, however, I wanted to keep this as a healthier more nutrient dense dessert. This is why I opted to base this recipe on my Healthy Double Chocolate Oat Cookie recipe and plan to experiment in the future and try this with my Healthy Chocolate Chip Oat Cookies too.

I use a mixture of gluten free oats and gluten free flour in this recipe but if you wanted you could make this giant cookie using just oats. Simply omit the flour and use 160g of oats instead of the amount noted. Personally I much prefer the texture that the addition of gluten free flour lends to the cookie. In order to prepare the oats you will need to blitz them in a food processor or blender for a few minutes until they take on a fine, powdery consistency.

I like these made with cacao powder, however, if you cannot get hold of this ingredient or find it a little too bitter you could do a simple swap and use cocoa powder instead. I like these cookies made with a mixture of dark chocolate, usually 80% or 85%, and a dairy free white chocolate as I find the flavours pair well together but you could use whatever you prefer. I use medium to large size vegan marshmallows but any size would work well for this.

Rather than using chocolate chips in this recipe I actually prefer to chop a bar of chocolate into chunks and use that so the pieces of chocolate are bigger. I tend to add most of the chocolate into the batter and hold half a handful back to scatter across the top once baked, however, you can just throw them all into the batter if preferred. With this recipe you could even experiment a little and throw a handful of marshmallows into the batter in place of some of the chocolate.

The dough fits perfectly into a 6″ x 6″ cake tin but if you wanted to you could actually use a skillet for this. You could also use a blowtorch to melt the marshmallows instead of popping the dessert under the grill, however, I realise not everyone has a blowtorch in their cupboard and I want this recipe to be accessible as possible which is why I have noted down the grilling method.

I would recommend making this just before eating so it is still hot when you enjoy it. The marshmallows will be gooey, the giant cookie will be soft and the chocolate chunks will be delicious gooey puddles. You could eat this cold later on but, trust me, the experience will not be anywhere near as enjoyable. As this is best served straight away while hot, I would suggest using coconut oil or butter to line the cake tin as opposed to parchment paper for ease.
