No Sugar Rock Cakes.

Rock cakes or rock buns, an english traditional! One of my husband’s favorites and one that brings him memories from his childhood. A few years ago, when we were visiting family in Greece, he tried a sweet bread roll with sultanas that we make in Greece and then he told me about rock cakes and how similar they taste. I’ve never heard of rock cakes before then and I will be honest, I was a bit confused about their name compared to their shape and texture. Although they are called cakes, their texture is more dense and something between cookies and cake, and they have a rough surface that resembles a rock.

These no refined sugar rock cakes are easy to prepare. No need for special baking skills here. It will take you less than 40 minutes to prepare the mixture and bake them. I often make them with my little girl, so if you have children, this can be a family fun activity and believe me they will love the end result!

History of Rock Cakes

Rock cakes go back to the second world war when the Ministry of food tried to promote a cake with less sugar and fewer eggs, an important savings in a time of strict rationing. In this recipe, I replace most of the sugar by using fruits and only use two tablespoons of coconut sugar which are optional and you can always omit if you prefer not to use any sugar at all.

Coconut Sugar

I like to use coconut sugar instead of white refined sugar when I make healthy baked treats. Coconut sugar is plant-based and not very processed, that’s why it retains some nutrients found in the coconut palm tree, like iron, zinc, calcium and potassium. Coconut sugar also has a lower GI compared to refined sugar, which means a lower risk of blood sugar spikes.

For all these reasons, I like to substitute often refined sugar with coconut sugar in my recipes. However, it is still sugar! It has the same amounts of fructose as refined sugar and the same calories. You should still treat it as any other sweetener and have it in moderation.

Ingredients & How-to

To make these low sugar rock cakes, you will need some basic baking ingredients butter, flour, baking powder, vanilla extract, egg and your special ingredients which are, sultanas or dried mixed fruits, an apple, a banana, cinnamon and optionally some coconut sugar.

Ingredients for low sugar rock cakes.

01. First, I add all the dry ingredients to a bowl, flour, coconut sugar, baking powder and cinnamon. I then add the cold butter, cut into cubes. Using my fingertips, I start rubbing the butter into the flour mixture until it resembles breadcrumbs.

02. If you shake the bowl then any lumps will come up to the surface. Try not to use your palms as you don’t want the butter to melt. If you have a food processor, you could also add the ingredients there and give it a few spins until you get a sandy texture.

Now, I add the dried mixed fruit to the flour mixture. If you don’t have dried mixed fruit then you could just use sultanas or raisins. I always go with whatever I have in my cupboard!

03. All the sweetness in these low sugar rock cakes comes from one banana and one apple and the two tablespoons of coconut sugar, which are optional. For the apple, I simply peel it and then using a hand grater, I coarsely grate it.

04. For the banana, I recommend using a ripe banana as they are sweeter and better for substituting sugar in baking. If you don’t have a ripe banana, then put one in the oven for 10 minutes or microwave it for 3-4 minutes and that will help. I use a masher or a fork to mash the banana and then add it to a bowl along with the egg, grated apple and the vanilla extract.

05. Finally, I mix the dry ingredients with the wet ones using a spatula or my hands. Using a spoon I place around 12 balls on a lined baking tray. The rock cakes don’t need to have a perfect shape, their surface doesn’t need to be smooth. After all, that’s why they are called rock cakes!

06. Now it’s time for the oven. I bake them for 15-20 minutes until they have a nice golden brown color. When you take them out of the oven, leave them to rest for 3-4 minutes before placing them on a wire rack to cool down completely.
