Description
You can make this the standard/regular way or veganize it if you prefer. This is a true hit in our family and I bake this on a regular basis!
Ingredients
- 2.6 cups – 625 ml buttermilk or vegan milk
- 2 tsp white vinegar, if using regular milk or plant-based milk instead of buttermilk
- 1 cup – 250 ml canola oil
- 1.5 – 2 cups – 375 to 500 ml sugar, depending on your preferred sweetness
- 2 L whole wheat flour, measured as 8 cups
- 90 ml baking powder, measured as 18 tsp
- 1 1/2 tsp salt
- 2 tsp baking soda
- 8 Weetabix biscuits, crushed into fine crumbs
- 1 cup – 250 ml sunflower seeds, and 1 cup – 250 ml pumpkin seeds, or a mixture of your favourite nuts and seeds
Instructions
- If you’re using regular milk or plant based milk, pour 625 ml milk into a jug, stir in 2 tsp white vinegar, and leave it for 10 minutes. It may look slightly curdled, which is perfectly fine. If you’re using buttermilk, skip the vinegar.
- Stir 250 ml canola oil and your chosen amount of sugar, either 375 ml for a less sweet rusk or 500 ml for a sweeter batch, into the milk or buttermilk mixture until combined.
- In a very large mixing bowl, combine 2 L whole wheat flour, 90 ml baking powder, 1 1/2 tsp salt, 2 tsp baking soda, the 8 crushed Weetabix biscuits, and 250 ml sunflower seeds, pumpkin seeds, or your chosen nut and seed mixture. Mix thoroughly so the raising agents and seeds are evenly distributed.
- Make a well in the centre of the dry ingredients. Pour in the milk, oil, and sugar mixture, then stir with a sturdy spatula until everything is evenly combined and no dry flour remains. The dough will be thick and sticky, so don’t expect it to resemble a smooth bread dough.
- Lightly grease your rusk pan or a deep baking pan with cooking spray. Transfer the dough into the pan and spread it evenly. With lightly oiled hands or an oiled spatula, press the dough into the corners and level the surface. Aim for an even thickness so the rusks bake consistently.
- Use an oiled knife or your greased rusk cutter to mark the dough into individual rusks. Cut deeply enough to make the portions easy to separate after baking, but don’t worry if they’re not perfectly uniform.
- Bake in a preheated oven at 400⁰F (200⁰C) for 18 to 20 minutes, or until the top is nicely browned and a skewer inserted into the centre comes out without wet batter. If you’re using a particularly deep pan, check the centre carefully and allow extra baking time if needed.
- Remove the pan from the oven and leave the baked slab to cool in the pan until it’s firm enough to handle, approximately 45 to 60 minutes. Carefully turn it out, separate the rusks along the marked lines, and cut through any sections that haven’t separated cleanly.
- Arrange the rusks in a single layer on a wire rack set over a baking tray. Place them in an oven preheated to 190⁰F (85⁰C) and leave them to dry for approximately 5 to 6 hours, or until they’re thoroughly dry and crisp throughout. Keep the oven door slightly ajar only if your oven’s manufacturer permits it and the oven can maintain a safe, steady low temperature.
- Let the rusks cool completely before packing them into a clean, dry, airtight container. Enjoy them with coffee, tea, or your favourite hot drink.

Additional Information, Tips and Suggestions
Choosing the right milk
- You can make these rusks with buttermilk, regular milk, or plant-based milk. If you’re using regular or plant-based milk, add 2 tsp white vinegar to 625 ml milk and leave it for 10 minutes before mixing. The milk may look slightly curdled, which is normal.
- Buttermilk provides natural acidity that works with the baking soda and adds a gentle tang. If you choose plant-based milk, unsweetened soy milk is a useful option because it generally provides more protein than many nut milks.
Getting the baking powder quantity right
- The recipe uses 90 ml of baking powder, equivalent to 18 tsp. Although this may seem like a generous amount, it’s been repeatedly tested, and it’s what you need to use. Measure it carefully and mix it thoroughly into the flour to distribute it evenly.
Adjusting the sweetness
- The original recipe uses 2 cups of sugar, but 1 1/2 cups works well if you prefer less sweetness. Both options are included in the recipe, so you can choose according to your taste.
- Keep in mind that sugar contributes to more than sweetness. It also affects browning, moisture, and texture, so reducing it substantially may change the finished rusks.
Choosing seeds and nuts
- Sunflower seeds and pumpkin seeds are my favourites for this recipe. You can use either one or combine them, keeping the total quantity at approximately 1 cup.
- Chopped nuts are another option, provided they’re suitable for everyone who will be eating the rusks. If you use salted pumpkin seeds or nuts, reduce the added salt to prevent the rusks from becoming too salty.
Baking and drying for the best crunch
- The initial bake sets the dough and develops its colour. The rusks should be nicely browned, and a skewer inserted into the centre should come out without wet batter.
- The second stage is just as important. Drying the rusks at 190⁰F (85⁰C) for approximately 5 to 6 hours removes the remaining moisture and creates their characteristic crisp texture.
- Thicker rusks may need longer. If they’re still soft in the centre after cooling, return them to the low oven and continue drying until they’re crisp throughout. Let them cool before judging the final texture, as they firm up further as they cool.
Can I prepare the dough ahead?
- For the best rise, mix and bake the dough promptly after combining the wet and dry ingredients. The baking soda begins reacting with the acidic milk mixture, so leaving the prepared dough sitting for an extended period may affect its lift.
- If you’re making several batches, prepare and bake them separately rather than mixing a huge quantity at once. This helps you distribute the raising agents evenly and manage the sticky dough more easily.
Storage and freshness
- Allow the rusks to cool completely before storing them in a clean, dry, airtight container. Keep the container in a cool, dry cupboard away from humidity. Refrigeration isn’t normally necessary for properly dried rusks, and the moisture inside a refrigerator can soften them.
- Thoroughly dried rusks may keep well for several weeks, but their actual shelf life depends on how completely they’re dried and the storage conditions. Check for softness, condensation, mould, or unusual smells, and discard any rusks showing signs of spoilage.
- If the rusks soften but show no signs of spoilage, you can refresh them in a low oven until crisp again. Let them cool completely before returning them to an airtight container.
Making larger quantities
- This recipe makes approximately 60 rusks, depending on the pan and portion size. If you want to bake four to six batches, mix each batch separately using the full quantities rather than multiplying everything into one enormous bowl.
- You can make one batch with sunflower seeds and another with pumpkin seeds to give your family a choice. Just ensure each batch is fully dried and cooled before packing it away.
Serving suggestions
- These rusks are especially good with coffee, tea, or another favourite hot drink. Their firm texture makes them suitable for dunking, and their less sweet variation works well when you want something crunchy without a very sugary biscuit.
- They also make a practical homemade offering when visiting family or friends. Pack them only after they’ve cooled completely so trapped steam doesn’t soften the rusks.

Whole Wheat Weetabix Rusks with Seeds offer a hearty crunch, a wholesome whole wheat base, and the satisfying texture of crushed Weetabix with sunflower or pumpkin seeds. They’re easy to customize with your preferred sweetness and seed combination, making them a lovely homemade treat to dunk in tea or coffee and share with family.

Hi…. Your recipe says 18 Teaspoons of baking powder? Is this correct or am I reading it wrong….? Thank you
Hi Paula. You have read it correctly. Yes it is 18. I know you may think its a lot but with all the flour its correct. I have modified the recipe over the years and bake it at least every 6-8 weeks and then make 4 batches at a time.
Being so American 😉 I didn’t really know what Weetabix was before this post. This take on it sounds yummy! Thanks for sharing at Will Blog for Comments #4.
Hi Jennifer. In SA we used to get Weet-Bix and now that we’re in Canada we get Weetabix but its basically the same thing.
Weet-Bix is a whole-grain wheat breakfast cereal created and manufactured in Australia and New Zealand by the Sanitarium Health Food Company, and in South Africa by Bokomo. Wheetabix is the U.K version which we do get in Canada.
d love to know the ingredients of the plain cereal. . Saw it at Will Blog for Comments #4, open August 21 – August 26! My shares are #10 and 11. Enjoy. Nancy Andres @ Colors 4 Health.
