How to Make Mary Berry Sugar-Free Carrot Cake
- Prepare the oven: Preheat the oven to 180°C or 160°C fan. Grease and line a 20cm round cake tin with baking parchment.
- Mix the dry ingredients: Sift the flour, baking powder, cinnamon, nutmeg and salt into a large bowl. Stir gently to combine.
- Combine the wet ingredients: In a separate bowl, whisk the eggs, oil, maple syrup and vanilla until smooth and well blended.
- Add the carrots: Fold the grated carrots and nuts, if using, into the wet mixture.
- Bring the batter together: Add the dry ingredients to the wet and fold carefully until just combined. Do not overmix.
- Bake: Spoon the mixture into the prepared tin and level the top. Bake for 40 to 45 minutes until golden and a skewer inserted into the centre comes out clean.
- Cool: Leave the cake in the tin for 10 minutes, then turn out onto a wire rack to cool completely.
- Make the topping: Beat the cream cheese, maple syrup and vanilla until smooth. Spread over the cooled cake if desired.

Tips for Best Results
How do I keep the cake moist?
Finely grate the carrots and avoid overbaking. Removing the cake as soon as the skewer is clean keeps it soft.
Can I make it completely dairy-free?
Yes, simply skip the topping or use a dairy-free cream cheese alternative.
What is the best natural sweetener to use?
Maple syrup gives a gentle flavour, while honey makes the cake slightly richer. Both work well.
Why did my cake sink?
This usually happens if the oven door is opened too early or the batter is overmixed.

- Add a spoon of Greek yoghurt on the side
