What Are South African Rusks?

South African rusks, also known as beskuit, are twice-baked biscuits traditionally enjoyed dunked into tea or coffee.

Unlike soft biscuits or cookies, rusks are baked until completely dry and crisp, making them perfect for storing in tins and enjoying over weeks.

They’re a staple in many South African homes and are often served:

• with early morning coffee
• during family visits
• on road trips
• on rainy days
• alongside tea with Ouma

This carrot cake version combines the warm spice flavours of classic carrot cake with the crunchy texture of traditional buttermilk rusks.

Step 1: Prepare the Oven for South African Rusks

Step 2: Mix the Dry Ingredients for Carrot Cake Rusks

In a large mixing bowl, combine:

• flour
• oats
• bran flakes
• brown sugar
• cinnamon
• mixed spice
• baking powder
• salt

Mix well.

Stir through the grated carrots, chopped pecans, and raisins if using.

Step 3. Add Wet Ingredients for the Rusks

In a separate bowl, whisk together:

• melted butter
• eggs
• buttermilk
• vanilla extract

Pour the wet mixture into the dry ingredients and mix until fully combined.

The dough should be:

• thick
• soft
• slightly sticky
• easy to press into the tray

Avoid adding extra flour unless absolutely necessary.

Step 4. Bake the Carrot Cake Rusks

Press the mixture firmly and evenly into the prepared baking tray.

Bake for:
40–45 minutes

The top should be golden brown and firm to the touch.

Do not overbake at this stage.

Step 5. Slice the Homemade Rusks While Warm

Allow the baked slab to cool for only 15–20 minutes.

While still warm, cut into chunky rusk fingers or squares.

Cutting while warm helps prevent crumbling and cracking.

Step 6. Dry the South African Rusks Until Crisp

Reduce the oven temperature to:
90–100°C

Arrange the rusks on baking trays or directly onto oven racks.

Dry for:
4–6 hours or overnight

Leave the oven door slightly open using a wooden spoon to allow moisture to escape.

The rusks should be completely dry and crisp.

Tips for the Best Buttermilk Rusks Texture

Don’t Let the Dough Become Too Dry

Toast the Pecans First

Toasting the pecans before adding them to the dough gives this carrot cake rusks recipe a richer bakery-style flavour.
