Rock cakes are a recipe that take me back to Domestic Science or Home Economics lessons at school. The name of the lesson kept changing but it was basically cooking and sewing.

Rock cakes were one of the recipes we learnt to make, easy to make and cook in forty minutes. They are also easy to transport home in a plastic tub to be admired by your parents. There is something restful about rubbing in butter to flour and the addition of the chocolate makes a nice surprise when eating them.

What are traditional British Rock Cakes?

Rock cakes, also known as rock buns are small cakes with a rough surface that look like rocks. They are supposed to have a hard surface but inside they are soft and crumbly and taste wonderful.

Rock cakes are a mix between a scone and a small bun like cake. A simple dough is made into rough looking balls and baked, rather than being rolled out like scones.

The cakes became common during the Second World War. They require fewer eggs and less sugar than ordinary cakes, which was important during the time of strict food rationing. Traditionally  they are fruit cakes but this recipe has a chocolate twist.

Children will also be family with rock buns from the Harry Potter books, where Hagrid’s was exactly like eating a rock. This recipe is for traditional rock cakes which taste amazing and will not damage your dental work!

Ingredients

There is a complete printable recipe further down the page if you scroll down.

These cakes use five main ingredients which are mainly store cupboard staples. You will probably be able to make them from ingredients that you already have in. You will need:

Can I use plain flour to make rock buns?

You can use plain flour but you will need to add some extra ingredients so the cakes will rise. Use 225g plain flour with 2 ½ tsp baking powder and 1 tsp salt. Mix together well.

Steps to make

Grease a baking tray and heat the oven to 180C, 350F, Gas Mark 4

Add the flour and salt to a bowl with the butter and margarine.

Rub the butter into the flour. Rubbing in is a technique where you use your fingertips to rub the flour and butter together. Lift the mixture up with your hands as you rub it in. This allows the air to pass through to keep the mixture cool. Keep going until the mixture resembles fine breadcrumbs.

If you are using a chocolate bar cut it into small chunks using scissors. This is easier if the chocolate has been in the fridge first. Add the chocolate and sugar to the flour and mix.

Make a well in the centre of the bowl and add the milk, egg and vanilla essence. Mix well until you get a soft dough.

Using two forks dollop the mixture onto the greased baking tray. You should get 12 rock buns. They should be around the same size but don’t need to look pretty.

    Oh what a fabulous book. I now want it in retrospect for my long gone childhood. I was brought up with AA Milne and rock cakes. I’ve been adding chocolate to my rock cakes in recent years and thought I was the first to do so. Haha, I should have known Pooh would have got there first. Thanks for joining in with this month’s challenge.
