This is a recipe for simple, moist, gluten-free carrot cake, using olive oil and almond flour, with a creamy mascarpone frosting or icing. This is the best carrot recipe – not too dry, not some sponge-like thing you get on planes or from the supermarket that barely even has any carrot in it – this is textured, moist, slightly crisp on the outside and spiced with cinnamon.
