My Gluten Free Carrot Sheet Cake is tried and tested by my chief coeliac taste tester. This is a gluten free version of my most popular cakes.
Since before I started my blog, my carrot cake has been my most popular cake. I get asked to make it time and time again and I am yet to find someone who doesn’t like it. I have wanted to make a gluten free version of my carrot cake for quite a while now.
My first attempt at adapting my recipe to being gluten free naively involved switching the plain flour to gluten free flour. Although the taste was there, the texture was not. It was too crumbly which isn’t ideal in a cake.
It was the wonderful Zoe that suggested using xanthan gum; something I hadn’t heard of before. Xanthan gum helps act as a binding agent which gluten free flour lacks. So the next time I saw Zoe, we made gluten free carrot cake take two with much more success resulting in my Gluten Free Carrot Sheet Cake.
The texture was much better and too dissimilar to my usual recipe including gluten. Zoe who has coeliac disease was very happy with the finished cake and it didn’t take too much to convince her to take most of the cake home with her. That’s a trick of mine – giving cake to people; having it in the house is too dangerous!
One tip I have for all of my carrot cake variations is to try and break up the sugar the best you can before adding the rest of the wet ingredients. My brown sugars always seen to get lumps in them and while small lumps will melt into the cake, it is easier to try and break up the larger lumps before the other ingredients are added.
This recipe doesn’t have to be used for a sheet cake, it can easily be made into cupcakes too. Depending on the size o the cupcake cases you use, they should take around 20 minutes to bake. These quantities should make between 10-12 cupcakes.
Although this recipe is intended to be gluten free, if you do not follow a gluten free diet you can use standard plain flour and omit the xanthan gum.
