Buttercream or Betty Crocker cream cheese style icing
Method
Cream butter and sugar until light and fluffy. Add the eggs one at a time and cream.
Fold in the grated carrot.
Add the flour, baking powder, baking soda, xantham gum and salt. Add raisins / nuts if using.
Spoon the mixture into individual cases and bake at 180c for 18-25 minutes depending on the size of the cases you are using. (If making one cake, split the mixture into two sponge tins and bake at 185c for 25 mins.)
Once the cakes have cooled, either leave them plain or top with buttercream icing. Optional: add 3 tbsp cream cheese to the icing. Decorate with Demerara sugar or carrot decorations.
