Potato Gluten Free Shortbread Cookies

Since I’ve discovered that heating nut flours like almond flour etc actually increases the oxidisation of PUFAs (poly unsaturated fatty acids) in them and kind of makes them toxic (eek!), you can understand why I’m not so keen to continue making up recipes with these nutty flours in it. These Potato Gluten Free Shortbread Cookies though have none of that and more of the good stuff.

So the best choice I’ve found that isn’t a grain either and doesn’t stack up your gluten overload is Potato Starch. I use it for cookies, for the crumble part on apple crumble and to thicken up sauces. I haven’t tried it in pancakes or cakes yet, so that may be next!

Potato Starch

There is Potato Starch, which is completely white and made only from the white potato and tends to give a light and fluffy texture. And Potato Flour, which is a creamy colour and made using the skins as well. Apparently the flour is a heavier weight, which would make your baked goods a bit dense and gummy.

So the starch is definitely what I use. The only problem is just to confuse everyone more, they name it ‘flour’ for both sometimes – like this one I buy…

It’s definitely the starch despite what it says on the packet! I get it from my local Coles. And on the back it says “Potato Flour is sometimes known as Potato Starch” Bahaha! Maybe for those who don’t know what they’re talking about!!

Anyway back to cookies… the best traditional shortbread biscuits have only 3 ingredients, flour, butter and sugar – it’s just getting the proportions right and cook time that can be tricky. I tried it with more butter first and it was just a bit too rich and completely spread out on the tray.

My taste testers gave the ‘yum’ approval for this final version, as they are light and almost powdery tasting and when a junior taste tester came back for more, I knew I was onto a winner. (Even though they look a bit boring!)

Coconut Sugar

I love the coconut sugar in this too, as it gives a rich malty flavour, but really you could use any sugar. (Not so sure about honey etc – perhaps if you try it, let me know if works.)

  • saucepan
  • Cookie tray


  • 2 cups potato starch
  • 1/2 cup butter
  • 1/2 cup coconut sugar
  • 1 tsp vanilla extract


  • Preheat oven to 180C.
  • Melt butter and vanilla.
  • Pour butter mix into flour and sugar. Mix until well combined and forms a dough.
  • It may feel a little crumbly, but as long as it can press together in the next step, then it’s fine. (If it doesn’t, then add a little more butter until you’re happy.)
  • Take a teaspoonful and roll into a ball in your hand and place on a parchment paper lined tray.
  • Flatten to suit. (I use the bottom of a glass with a flat edge.)
  • Cook at 180C for 10 mins, just until slightly browned.
  • Remove from oven and allow to cool before touching or you will wreck them!


Store in an airtight container in the pantry for up to about a week. (Mine lasted about 2 weeks as I only eat them slowly, so it does last that long.)

For anyone who is concerned about the sugar content or ‘white’ flour in this recipe; turns out these are more easily digestible than some ‘health’ foods. Certain levels of sugars and carbs eaten with high levels of nutrients are actually recommended for optimal body health.

    Sadly they are beginning to put nano particles in flours to make it easier to flow. Dr. Peat mentioned this in a recent podcast as he was concerned about powder milk which he liked in pan cakes that he used to like making!

    Hi Chris, yes I did see that, probably the day before my new recipe book Sweet Treats was due to launch which has milk powder in it! I do think we need to be diligent and definitely contact companies and ask them to prove it doesn’t have it. I read a bit about it here in Australia and they were concerned about baby formula having it. Apparently we have a nano particle watchdog group here and all they say is that it’s not harmful – so they can’t be trusted! I think though the food industry in the US is probably the worst with the chemicals they try and pass as food. We need to be diligent for sure but not too paranoid or else we wouldn’t eat anything. Do the best you can do. Cheers and thanks for stopping by!

    Hi Chris, yes the whole food industry is turning into quite a disgrace. I think it’s the worst in the USA though but I’m sure Australia will follow suit a few years down the track. In regard to milk powder I did find an organic supplier here in Australia who has verified that they do not have the nano particles, so I will be promoting them whenever I mention a recipe with milk powder in it. I never did like the milk powder pancakes though, I tried to make them once and it was just a flat, easily burnt disaster that didn’t taste that great. I’ve put a new potato crunchy type hash brown in my new book though that’s better and no flour! Cheers Kristy
