Mary Berry Sugar-Free Carrot Cake Ingredients
For the Cake:
- 200ml (7fl oz) vegetable oil
- 3 free-range eggs
- 175ml (6fl oz) agave syrup (also known as agave nectar)
- 400g (14oz) carrots, peeled and grated
- 275g (9¾oz) self-raising flour
- 2 tsp baking powder
- 1 tsp ground cinnamon
- 1 tsp mixed spice
- 150g (5½oz) sultanas
- 150g (5½oz) walnuts pieces
- 1 orange, finely grated zest only
For the Frosting:
- 400g (14oz) full-fat cream cheese
- 50g (1¾oz) unsalted butter, softened
- 50ml (2fl oz) maple syrup
- 25g (1oz) walnut pieces, chopped, to decorate
- Ground cinnamon, for dusting
How To Make Mary Berry’s Sugar-Free Carrot Cake
- Prep the oven and tins: Preheat the oven to 180°C/160°C Fan/Gas 4. Oil and line the bases of two 20cm (8in) round sandwich tins with non-stick baking paper.
- Mix the wet ingredients: Pour the vegetable oil into a large mixing bowl with the eggs and agave syrup and beat them together. Stir in the grated carrots.
- Combine the dry ingredients: In a separate bowl, sieve the flour, baking powder, cinnamon, and mixed spice together. Stir in the sultanas, walnuts, and orange zest to coat them in the flour.
- Make the batter and bake: Tip the flour mixture into the carrot mixture and stir gently until everything is well combined. Divide the mixture evenly between the two prepared tins and bake for 40 minutes. You may need to cover the tops with foil after 20-30 minutes to prevent them from burning.
- Cool the cakes: Let the cakes cool in their tins for 5 minutes before turning them out onto a wire rack to cool completely.
- Make the frosting: Place the cream cheese in a piece of clean muslin or a thin kitchen cloth and squeeze out any excess liquid. In a bowl, beat the “drained” cream cheese until smooth, then beat in the softened butter and maple syrup. Refrigerate until needed.
- Assemble the cake: Sandwich the two cooled cake layers together with half of the frosting. Spread a thin layer of the remaining frosting over the top of the cake. Decorate with chopped walnuts and a dusting of cinnamon.

Recipe Tips
- How to get the best frosting? The secret Mary Berry tip is to squeeze the excess liquid from the cream cheese using a muslin cloth. This removes moisture and prevents the frosting from being too wet or runny, especially when using a natural liquid sweetener like maple syrup.
- Can I make this ahead of time? Yes. The un-frosted cake layers can be baked a day in advance and stored in an airtight container. The frosting can also be made ahead and stored in the fridge; just let it soften slightly and give it a quick whip before using.
- How to prevent the cake from burning? Fruit cakes with natural sugars can brown quickly. As the recipe suggests, covering the tops of the cakes loosely with aluminum foil after about 20-30 minutes of baking will prevent them from getting too dark before the center is cooked through.
- Can I use a different sweetener? This recipe is specifically designed to work with liquid natural sweeteners like agave and maple syrup. Using granulated sweeteners would alter the moisture balance and texture of the cake.
What To Serve With Sugar-Free Carrot Cake

How To Store Sugar-Free Carrot Cake
- Refrigerate: Due to the cream cheese frosting, this cake must be stored in the refrigerator. Keep it in an airtight container, and it will stay moist and delicious for up to 4-5 days. For the best flavor, let it sit at room temperature for about 20 minutes before serving.
