Pour the plain flour into a mixing bowl and add 1/2 scoop of protein powder, along with the sweetener and baking soda. Give it all a mix.
Add the maple syrup, vanilla extract, and plain greek yogurt. Give it another mix and continue until it’s silky smooth. Now add in the chocolate chips and give it a final mix.
On a baking tray, add the cookie mixture by making blobs (the size of each blob will dictate how many cookies you end up with). You can also add some more chocolate chips at this point if you wish.
Bake in the oven at 180 degrees for 4-8 minutes (every oven is different so it may take a few minutes longer - make sure not to over bake it or it will be dry).
Once done, let them stand for 10 minutes and stack them on top to serve. Drizzle melted chocolate over the top for some extra flavour!
