Buttermilk bran rusks with raisins and seeds
I have taken my best buttermilk bran rusk recipe and added raisins and seeds to it. These are so delicious dunked into your tea or coffee.
Since I have added raisins to this recipe I reduced the sugar down by about 25% from my original recipe. I give all the options below so you can choose which you prefer.
I have also played around using half artificial sugar and a little less than half the sugar and this also worked out very well.

Rusks are a classic South African confection and something missed by expats living abroad. They are especially delicious in winter with a hot drink.
As they are quite time-consuming to make, you might want to double the batch. They dry out particularly well if you have a fan-forced oven. This way you can put 2 large trays in at a time.
Tips for making Buttermilk bran rusks
- Mix the dry ingredients together to ensure the baking powder is well incorporated. Then add the wet ingredients.
- The batter for rusks is quite dense, so it’s best to make these by hand.
- Rusks are first baked in a moderate oven for 30 minutes before cooling and then cutting.
- Once cool, use a very sharp knife to slice them into the size you prefer. I recommend slicing them thinner as these will dry out more easily.

Hi Sam! May I ask, what whole-wheat flour do you use for this recipe? All come across is cake or bread flour, or “wheat bran” flour – is this the one to go for? In SA. Thanks so much, look forward to trying them for a reduced sugar option!
Hi Meg. You get wholewheat flour in SA. Snowflake and Golden cloud make it as well as other milling companies like Eureka and Gideon. They have bits of the wheat kernel in. You should get this at any supermarket.
Really 250 grams of butter?
Hi and yes its 250 grams of butter for the recipe
Great and easy recipe.
Very tasty rusks.
I replaced the brown flour with white and the buttermilk with double cream plain yoghurt. Works perfectly.
Hi Evan, I am so glad you enjoyed this rusk recipe.
This recipe is amazing! I’ve already made it once, and now I’ve got some dry ingredients ready for another batch, but realise that my family don’t like raisins – what can I substitute? Nuts perhaps?
Hi, Claire, you can just leave them out entirely or add dried cranberries instead if you want to keep a fruity element.
Gurl, nothing could have prepared me for the lost real estate when I was cutting them up. I, in the end, had a bowl of broken up pieces – fun snack but it was sad. Otherwise, such a great recipe ! Thank you thank you.
Hi Uvile, there is always a little bit of crumbling when making rusks but it shouldnt be as seer as you describe. It sounds ike the dough was too dry.
