Homemade Rusks

In this post, we’ll explore the history and heart behind rusks, show you how to make a basic batch from scratch, and give you three popular variations: buttermilk rusks, muesli/bran rusks, and classic Ouma-style rusks. Whether you’re baking for breakfast, a weekend treat, or gifting a homemade snack, these rusks are the perfect dunk-worthy delight.

What Are Rusks?

Rusks are dry, crunchy biscuits that are twice-baked, first like a loaf or slab, and then sliced and slowly dried in the oven. The result is a hard but delightful biscuit that's perfect for dunking into hot drinks. Traditionally made in Afrikaans households, rusks are now beloved by South Africans of all backgrounds.

A Brief History of Rusks in South Africa

Rusks began as a practical solution; Afrikaner families needed a way to preserve bread for long journeys across South Africa. What began as a survival food evolved into a comforting staple.

In 1939, the iconic Ouma Rusks brand was born in a small town called Molteno, becoming a household name across the country. Today, homemade rusks still carry a sense of tradition, comfort, and togetherness.
