These healthy oat cookies are so delicious and are bursting with chocolate chunks. I love the combination of dark chocolate and sea salt together and these soft centre cookies make the perfect vessel for this flavour pairing.

I have been wanting to create a healthier, more traditional cookie for a while now and I am so happy with how these turned out. I do have a ‘healthy’ cookie on my website in the form of my Chocolate Chip Chickpea Cookies but I wanted to create something more in line with ‘regular’ cookies . These oat cookies are perfect for those who like their cookies to be soft in the centre and packed with flavour. If you like these cookies you may like my double chocolate version which you can find here or my Caramel Apple Cookie version.

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.

I like these cookies made with dark chocolate, usually 80% or 85%, as I find this is what works best flavourwise with the sea salt but you could use whatever kind of chocolate you prefer, including none vegan chocolate if you are not dairy free.

Rather than using chocolate chips in this recipe I actually prefer to chop a bar of dark 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.

If you are not on a gluten free diet you can use regular plain flour and oats in this recipe. You could try this cookie recipe with a handful of chopped nuts in too if you fancied.

I usually make six cookies from this recipe but you could make more depending on the size. Use a tablespoon or ice cream scoop to scoop out evenly sized chunks of batter, roll them into balls and place them on a lined baking tray roughly two inches apart. Press down gently on each ball to shape them into discs.

When you remove these from the oven, bash the tray a couple of times against a surface that the heat won’t damage to help the cookies flatten a little bit more. If any of the cookies are a funny shape, you can use the back of a spoon to help shape the cookies into perfect circles while they are still hot. Allow to cool completely before removing from the tray.

These cookies will keep in an airtight container for up to five days.
