Lightly Spiced Fish Biscuits for Fans of The Octonauts

My little one is a big fan of Octonauts, together with her big sister they even made their very own gups out of cardboard boxes, decorated them and spend hours inside. Shellington (the sea otter) is her favourite character, she even sometimes ask to call her that.

One of those days she asked me if we can make fish biscuits. I agreed without realizing that among about 100 cookie cutters in the house there is not a single one that resembles fish, even a bit. I walked all Brighton’s stores in search for fish cookie cutters… without luck. Finally I got one on Amazon but it was not an easy task as well as  she was very picky about shape of the fish she needed (!)

Along the cookie cutter I ordered also little Octonauts memory game to make up for the fish cutter being not round enough.

Octonauts fish biscuits recipe


  • 2 cups of plain flour + some more for dusting
  • 1 tsp baking powder
  • 1 pinch of salt
  • 150 g real butter, unsalted (softened)
  • ½ cup golden caster sugar
  • ½ tsp ready ginger bread spice mix or combination of cinnamon, nutmeg, ginger, cloves and all spice
  • 1 egg


Octonauts fish cookies recipe


  1. In a mixing bowl combine all dry ingredients, then add softened butter and egg.
  2. Knead the dough until well combined and place in the fridge for about half an hour so it will be easier to cut out the shapes when the dough is a bit harder.
  3. Roll piece of the dough at the time on floured surface, cut out the biscuits with cutters.
  4. Place them on baking trays and bake in the oven preheated to 160°C (320°F) until golden brown.
  5. Leave aside to cool down completely before serving.

Makes about 40 small cookies.


Those fish biscuits are not very sweet and would be perfect for picnics or even lunch boxes.

For a special treat top them with some chocolate spread or jam.

Your thoughts…

  1. Ha – I can completely identify with the shape of the biscuits needing to be EXACT! My kids would do the same. These sound lovely :)

  2. Fantastic! My Octonauts fans would love these treats :)

  3. Thank you Kate and Elizabeth :) I’m glad to hear that.

  4. Hi, I used regular sugar as that’s what I had. The dough was very crumbly. So I had to add some milk to knead it and get it to the right consistency. Was it the sugar that made the dough so crumbly? I would love to fix what I did wrong. They turned out great btw and the kids loved it. (I used only cinnamon since they don’t like spice).
    Also, if I want to make them gluten free, would gluten free flour work in the same proportion?
    Thank you, it was such fun making these with my kids, perfect for a Saturday afternoon.

  5. I came across this site when I searched for fish biscuits because who else would be searching for them except for Octonauts fans! I made the recipe as listed and guessed with the spices – I crushed 2 tiny balls of Allspice, 3 whole cloves, and then filled up the rest of the 1/2 teaspoon with cinnamon, as I didn’t have any nutmeg. I also replaced the golden caster sugar with regular white sugar. The first time, I didn’t roll the dough flat enough (about 5 mm this time) so the fish biscuits came out too thick but I will know to make them thinner next time. Also, my fish cookie cutters were way too big so I had a smaller number of giant cookies and I’d rather have a bunch of smaller cookies for portion control – the kids can’t control themselves! I think since I used white sugar, they didn’t brown so I just took them out of the oven when the edges started to brown slightly. Overall, the taste was wonderful, not too sweet which is great for the little ones! I’ll definitely make these again and roll them out thinner! Thanks so much for the recipe!

  6. Thank you for this! My 3yo has been begging me for fish biscuits. Her and her brother love octonauts. I’m excited to try this with her as she loves to help me bake.
