Rusks are a familiar part of many South African homes, usually tucked away in the biscuit tin for when the kettle goes on.

They’re at their best when dunked into a strong cup of coffee or tea, softening just enough before that familiar crunch comes through again.

From classic buttermilk to bran, muesli and even choc-chip versions, there’s now plenty of variety on the shelves, but the traditional buttermilk rusk is still the one most people reach for first.

With grocery prices continuing to rise, everyday treats like this are becoming more expensive.

That’s where homemade rusks start to make sense. The ingredients are simple and affordable, and the method is straightforward, but the drying stage does take time.

The oven needs to stay on for several hours at a low temperature, so it’s worth being mindful of electricity use while they slowly dry out.

What you get in return is a generous batch of golden, crisp rusks that keep well for weeks and taste exactly like the kind many South Africans grew up with.

Homemade Buttermilk Rusks Recipe

Ingredients

  • 1kg self-raising flour
  • 250g sugar
  • 250g butter, softened
  • 1 teaspoon salt
  • 2 extra-large eggs
  • 500ml buttermilk

Method

  • Preheat the oven to 180°C and line a large baking tray with baking paper.
  • In a bowl, beat the eggs and sugar together until smooth and slightly pale.
  • Add the buttermilk and mix until fully combined.
  • In a separate large bowl, sift the flour and mix in the salt.
  • Rub the softened butter into the flour mixture using your fingertips until it resembles coarse crumbs and the butter is evenly distributed.
  • Pour the wet mixture into the dry ingredients and mix until a soft dough forms. It should be thick, similar to cookie dough.
  • Press the dough evenly into the prepared tray, smoothing it out with your hands or a rolling pin.
  • Bake for 40 to 50 minutes, or until golden brown and cooked through.
  • Allow the baked slab to cool slightly before cutting it into rectangular rusk shapes.
  • Arrange the pieces on a wire rack set over a baking tray so air can circulate.
  • Reduce the oven temperature to 90°C to 100°C and dry the rusks for 3 to 5 hours, turning them occasionally if needed. They are ready when completely dry and hard throughout.
  • Let them cool fully before storing in an airtight container.

A few simple tips for better rusks

The drying stage is where patience matters most. Low heat is what gives rusks their signature crunch, so rushing it will only leave you with a soft centre that doesn’t keep well.

If your oven has a fan function, it helps speed up moisture removal slightly without affecting texture. Leaving the oven door slightly ajar during the last hour can also help release trapped steam.

Once cooled properly, these rusks keep well for weeks, making them ideal for busy mornings when all you need is something quick to dunk into your coffee.
