These Healthy S’mores Oat Cookie Cups are absolutely delicious and incorporate all the elements of traditional s’mores!

To me, November is all about the marshmallows so I thought it was the perfect time to create this healthier twist on s’mores. This is a great alternative to the traditional way of making them when the weather is too bad to sit outside with a fire! I based the cracker element on my Healthy Oat Chocolate Chip Cookies and used vegan marshmallows and chocolate to create a suitable nut free, gluten free and vegan version more people can enjoy.

When you bake these, the cookies will lose their shape and start to close around the marshmallow and chocolate which is actually really useful as they would be really messy if not! I personally think these are best enjoyed hot with the chocolate melted, however, they are still delicious enjoyed when cool, (as shown in the photots), the chocolate will just harden back up. These will last for up to five days in an airtight container.

I use a mixture of gluten free oats and gluten free flour in this recipe but if you wanted you could make these using just oats. Simply omit the flour and use 175g of oats instead of the amount noted. Personally I much prefer the texture that the addition of gluten free flour lends to these. 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. If you are not on a gluten free diet you can use regular plain flour and oats in this recipe.

I tend to use a bar of dairy free milk chocolate when creating these s’mores cookie cups but you could use dark or white if preferred. I simply break a few pieces off the bar and layer them between the bottom cookie disc and the marshmallow, however, you could go really wild and put them above the marshmallow instead. You could also use a handful of chocolate chips instead of chocolate from a bar if thats all you had. I have noted you will need medium to large sized marshmallows in this, however, half a handful of mini marshmallows would work too.

I use a silicone muffin tray to create these cups, however, you could use individual brownie trays to create a similar dessert this is just a different shape depending what you have to hand.
