Perfect Gluten free Buttermilk Rusks

Gluten-free Buttermilk rusks

It is high time that I published another rusk recipe, and not just any rusk a GF Buttermilk rusk! You only need a few ingredients and even I was surprised at how good it turned out. It has the perfect crumb and there were no breaking and almost no crumbs, except the ones from eating them.

I had about four just trying to create a reel with taking a bite and breaking the rusks in half. I am not complaining. Tasting comes with the job description.

These Buttermilk rusks are easy and delicious to make and the bonus is they are gluten-free and low in sugar. You could also replace the sugar with erythritol.

Gluten-free Buttermilk Rusks

I love rusks, with early morning coffee on camping trips, holidays, hiking trips, and coffee in bed. It has been very much ingrained in me. If there are rusks in my home I will eat them. So I don’t buy them often and to the disappointment of my family, I don’t bake them often. For a lot of people that are Gluten-free, rusks are one of those things that they feel pretty bummed about not being able to eat. And the ones available in the supermarket are extremely expensive and really don’t taste that great either.

Rusks or beskuit are very much a South African thing and are basically dried biscuits something similar to biscotti but less sweet. It can be dunk in coffee & tea. It is often eaten for breakfast. If you have never made your own rusks you won’t realise what high quantities of butter and sugar are in rusks. Our grandmothers really did know how to add sugar & butter to baked goods. Some recipes claim to be healthy but in reality, only the fibre has been increased by adding bran.

I have tested many rusks recipes, reducing sugar, and making them vegan. Adding various gluten-free flour blends has ended up rock hard or a crumbly mess.

So developing these ‘Healthier’ gluten-free rusks had me feeling like I won the rusk Lotto.  This batch got the thumbs up from my children and husband but, next time I will double up the recipe because it did not last long at all.

I have kept it simple and used Health connection’s gluten-free self-rising flour. And also did not add seed oil but olive oil. Coconut oil will also work.  I  used 3/4 cup’s of sugar but you can always lower it to 1/2 a cup.

You can also try your hand at making your own gluten-free flour mix, try this recipe and store in a jar.


290 g white rice flour
290g brown rice flour
230g potato flour
175g tapioca flour
14g xantum gum

Sieve ingredients together a few times to make sure it is mixed through. Also, use balloon whisk to stir.
Store in a 1L glass container. Use instead of wheat flour in baking. But when baking these rusks, measure out 500g of flour and add in 2 tsp baking powder and 1 tsp bicarbonate of soda.

I love my small rusk tray from Panneman you can order online and they deliver everywhere in South Africa. It makes rusk making so much easier. Just grease and press frame into dough before baking. But don’t bake with frame. It makes cutting so much easier and the results are a perfect cut rusk.

Hope you enjoy making them and that you are happy with the results. They taste a bit like Scottish shortbread and if you can’t have gluten you will be very happy to have find a rusk that you could make yourself and enjoy,

Perfect Gluten free Buttermilk Rusks

Delicious and perfect Gluten-free rusks, not crumbly and the dough is easy to work with.

Taste delicious, a bit like Scottish shortbread.



500g Health connection Gluten-free Self raising flour blend

1 tsp salt

3/4 cup demererara sugar

150ml buttermilk

125g butter melted

2 eggs

1/4 cup olive oil

5ml vanilla


Preheat oven to 180˚C

Add flour and salt and sugar to a large mixing bowl and stir.

Measure the buttermilk in a measuring jug and add eggs, vanilla, melted butter and olive oil. Mix with a fork and add the wet ingredients to the dry ingredients and mix until you get a thick dough-like batter. Add a little extra flour if too sticky.

Empty the mixture into a baking tray lined with baking paper and greased with oil or butter. The baking tray should be about 23 x 33cm and 3-5 cm deep. I just use my rusk baking trays, they are fairly large so I just fill the pan halfway and then press with the tray cutter.

Bake for about 45minutes until cooked and slightly brown, gluten-free flour does not brown ass well as normal wheat flour.

Remove and allow to cool, turn out onto a large chopping board and cut into even fingers. Place back in baking tray on sides. Leave some space between rusks. If it is easier you could also cut the rusks in the tray and just turn them sideways.

Dry out overnight (8-9 hours) in a 60˚C oven or for 6 hours in a 100˚C oven. Turn them over once if you can so the rusks can dry on both sides.

Another drying method I often use is to preheat the oven for about 10 minutes and then turn the oven off. Leave the rusks in the oven until completely cooled down.  Or place the rusks back in a hot oven after you used it for something else. And let the oven cool down with the rusks inside. Repeat this process about 3-4 times until the rusks are dry. This will save you some electricity costs.


Any gluten-free self-raising flour blend should work for this recipe. It is normally a combination of rice flour, potato flour, tapioca flour, maize flour, raising agents and xanthan gum
