The original sardine oatcake recipe

This is personally my favourite recipe on my blog, partly cause it was the first original treat I made myself that worked out.  If you need super high-value treats – you’ve just found them!  Your dog will love these oatcakes; they are tasty, healthy, smell great, and just so easy to make!  And from preparation to cooking time they take less than one hour!

When I was thinking about a new recipe I could come up with I thought about making a type of oat based doggy flapjack then found that oatcakes were even easier to make and the perfect treat recipe to use fish!

I’ve taken these out with me several times when I’ve been dog walking and they are great for getting the attention of a dog who’s mind wanders when out for a walk!

Very simple to make, all you need is 6 ingredients and a biscuit cutter.

 

INGREDIENTS

  • 2 tins of sardines in oil (2x120g)
  • 60g (1/3 cup) of wholemeal flour
  • 300g (1 1/3 cups) of oats
  • 150ml Chicken broth (homemade broth is best)
  • 1 egg

METHOD

broth in a jug

Make around 150ml (1/4 pint) of broth or stock.  Chicken will do.  If using cubes get the low salt ones.

sardines in a mixing bowl

Add the two tins of sardines to a bowl (including the oil)!

mashed sardines

Mash the sardines thoroughly with a fork!

egg

Add an egg

oatcake ingedients in a bowl

Add the 300g (10oz) of oats and 60g (2oz) of wholemeal flour

adding broth to mixing bowl

Add a little of broth to bowl.  To start with try adding 1/3 of your broth.

Mix ingredients with your hands and make a dough ball!  Too dry?  Add more broth.  Too wet?  Add some flour or oatmeal.

If you’ve made these before, you will know what to expect

How to store

As a general guide if meat protein is present in recipe then it will last around 3 to 5 days stored in a cool place.  If it has second class protein in it eg. cheese, lentils, eggs, etc, then they will store for about 10 days in a cool place. If there is no meat or second class proteins present then it will last around 3 weeks before they go soft like human biscuits.

  1. Hi i love the ideas of these biscuits and also the other alternatives that have been suggested. Im just wondering thou, is yeast and cheese not good for them? have been told by my vet not to give either?

  2. Hi
    I just wondered if you’ve tried the sardine oatcakes with gluten free flour?

    • No yet, but I’m sure it would work jut a well

    • Yes. Gluten free flour works as a like for like replacement

  3. Great liver cake recipe. I cut mine while warm and then popped it back in the oven until the pieces were dry and crunchy. No need to freeze if they last that long! My dog trainer recommends brewers yeast as a flea deterrent – could that be added to the mix do you think?

  4. Liver cake is an absolute winner. Sardine biscuits I found a bit crumbly. Added an egg and some cheese to second batch and they were much better
    Husband tried liver cake and I ate the biscuits which I thought pretty good myself :~)

  5. I was searching for a recipe that contained ingredients I have to hand and this is one of the few ones I have found. I just made it and me and Molly the Dog like it. Will be feeding it to husband later and will report back on the state of his coat…. I will complain to Carol if his coat isn’t shiney 🙂

    • Hey Sue!

      Glad you like it. This is one of my faves!

  6. Hello Jamie – I have just made your Sardine Oakcakes and Tyson our West Highland Terrier who has loads of allergies so can only be fed on our food consisting of salmon, rice, and veg – followed me around whilst cooking and was even crying for them – so gone down well thank you.

    • Hey Karen, thanks for letting me know, I’m glad Tyson likes them. Yeah, the westies are really prone to allergies, I know 4 and they all suffer from it.

  7. Just a quick query – how long will the biscuits keep in an airtight box or in a bag? Thanks

    • I make 1/2 a batch and in an airtight container they last weeks unless the dogs get at the container (which has happened) in which case they last seconds

  8. Hi can you tell me if the oatcakes and also the liver biscuits are ok for dogs with epilepsy.
    Thank you

  9. I made the liver cake to start with. Charlie loved it and so do all his friends. Sardine biscuit’s are also a good training treat and so easy to make. My husband has tried all the treats I have made for Charlie. He now has a lovely shiny coat. I regularly make these treats and made little doggy bags for Charlie’s 1st birthday. His friends want him to have birthdays every week.

    • Hi Carol! yeah these sardine oatcakes are my fav treat of all and they are easy and that does matter. Glad your dog and his friends like them!

    • Ha Ha Ha that reads as if your Husband now has a lovely shiny coat
