Ingredients & Possible Substitutions
Oats are an amazing ingredient to bake with and they are pretty healthy too. I use basic oats most of the time, but any other type of oats will be fine to use for this recipe. You are welcome to use gluten-free oats if you are making this recipe gluten-free.
I’ve used plain flour with this recipe, but you can also use Gluten-Free or All-Purpose Flour. If you are using gluten-free flour don’t forget to add a 1/2 teaspoon of xanthan gum (unless it’s already mixed in for you in your flour mix).
Spelt or buckwheat flour would work well with this recipe. To keep the cookies light, use a mix of 50% spelt or buckwheat flour and 50% plain flour.
You can use any kind of sugar with this recipe, but white caster sugar works best for me. If you use darker sugars, the mint might get lost in the caramelised flavour.
Baking powder will give you an even rise with this recipe. If you want to keep this recipe gluten-free, just double check that your baking powder is also gluten free.
I’ve used basic sunflower oil, but you can also use vegetable oil.
A large pinch of salt will help to balance out the flavours in this recipe.
You might need some milk to bring the cookie dough together to achieve a soft (but still firm) consistency). You can use a dairy-free milk or any kind of milk for this recipe. A watered down white yoghurt, cream or buttermilk would also work with this recipe well.
If you are after a vegan/vegetarian version of this recipe, use one tablespoon of chia seeds mixed with 3 tablespoons of water and left for about 1-24 hrs to soak up before you use it.
The longer you leave the chia seeds the better, as they soak up the water and turn into jelly like consistency. You can use ground chia seeds or regular (non-milled chia seeds).
You might need to adjust the amount of mint extract in this recipe depending on how strong your extract is. You want to make sure you have a good strong flavour, as when you bake the cookies, the flavour will get a little more mellow.
This recipe would also work with fresh mint if you wanted to add some in, but I’d still leave some mint extract in, to make sure there is enough flavour.

How to make Mint & Chocolate Oat Cookies
Preheat your oven to 375°F (180C for fan oven).
Line a couple of cookie sheets with baking parchment paper.
In a large mixing bowl measure out the flour, oats, baking powder and a very large pinch of salt and mix until all combined.
In another bowl or a jug mix together the vegetable oil, milk, egg and mint essence.
Add the wet ingredients to the flour ingredients and mix them together. There is no need to cream or overmix the dough, just bring it all together.
Add the chocolate chips and carefully stir them in. I normally add about 1/2 pack (about 50 grams) and then I add more because it doesn’t look like there is enough. Anything up to about 100 grams (1 packet) will work with this recipe, so it really depends on how much you have or how much chocolate do you want to have in your cookies.
Using a desert spoon, scoop the dough and drop on your baking tray, making sure that you leave good space between each cookie. Use more trays if needed as the cookies will spread a little.
Place in the middle of your oven and bake for 10 minutes or until the cookies start to crack a little.
Using the greaseproof paper, lift your cookies from the baking tray and place them on the cooling rack. Leave to cool down completely.
It all depends on how big you make your cookies, but I find that I usually make about 12-16 large cookies from this dough batch. If you are making your cookies smaller, they will bake quicker, so bake them for about 5-7 minutes.
Scaling up or down this recipe
You are welcome to make 1/2 the recipe (providing you have 1/2 egg – e.g. leftover from another recipe or use 1/4 of mashed banana).
You are welcome to double or triple this recipe to make more cookies if you are baking for a school bake sale or planning a party. These cookies freeze well, so you can make a bigger batch and then freeze them for later.
How to store cookies
It’s best to store your cookies in an airtight container like a plastic tub, cookie jar or large glass jar. They will be also perfectly fine in a plastic bag.
You can freeze these cookies on the day you’ve made them and keep them in the freezer for up to 3 months. Defrost in a room temperature, leaving the freezer bag open to prevent the biscuits from absorbing too much moisture.
