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 Kait!

    Thanks for the comment! I walk a ‘Milo’ but he is a Golden Retriever!

  2. Hi Jamie just wanted to say that your website for dog biscuits has to be the best around. My lurcher has auto immune disorder which means she can’t eat meat or meat derivatives but she can have fish. These sardines oatcakes are one of her favourites so thanks again for the recipe. For general interest I freeze mine and just put half a dozen in her biscuit tin at a time.

    • Thanks Kate. This is my favourite biscuit recipe!

  3. Hi Jamie,

    Just wanted to let you know your recipes are great.

    My lab loves the sardine oatcakes and the Tuna cake.

    I did try the banana bombs but couldn’t get them to work.

    Liver cake next.

    Once again thanks for sharing your great recipes.

  4. Am so glad I found this website – have made the sardine oatcakes for my 4 year old staffy who was following me around the kitchen whilst I was making them!! Anyway they have been wolfed down so thanks for sharing

    • Hi Sue!

      Thanks for your lovely comments! Sardine oatcakes are one of my fav treats! All dogs love them!

  5. I am going to try these but also some berry ones as my dogs love cranberries and bluberries, will try with bananas, apple and herbs do many different varieties with the basic ingredients. Watch out dogs and cats, Mummy is going to be baking.

  6. This recipe works well with bananas instead of sardines, I used four bananas but three would probably be enough & I didn’t need any water. My lab Tess loves both versions.

    • Thanks Liz! Sounds like a great idea!

  7. Thank you 🙂

  8. Oh my, oh my… just checked out this recipe. These have to be next, they have to be next… Where’s Bernice? Where’s Bernice? Can she make these next? eh? eh? Sardines… that’s fish right? I loves fish… I really loves fish… I’ll give her a paw, that’ll work…

    Jamie I’ll keep you posted, need to go and work my magic. Wish me luck ;*)

  9. I’ve made the sardine oat cakes several times. My dogs love them. However, since they have no preservatives, they have molded for me after 6 or 7 days. So I just freeze or refrigerate them.

    • Thanks Bev. I’ve never had them longer than 2 days so had no idea about their life.
