Sophie Faldo’s Cinnamon Roll Doughnut Recipe:

For the doughnuts:

250g self-raising flour

2 tsp ground ginger

2 tsp ground cinnamon

1 tsp baking powder

½ tsp salt

150g boiling water

100g unsalted butter

100g soft light brown sugar

150g golden syrup

1 large egg

For the frosting:

120g cream cheese

80g unsalted butter

300g icing sugar

2 tsp maple syrup (optional)

Crushed biscuits to decorate

Gold leaf (optional)


Preheat the oven to 175°C and grease the doughnut pans with butter.

Sift the flour and add it to the dry ingredients.

Mix the dry ingredients in a bowl.

Whisk together the water, butter, sugar and syrup until melted and combined.

Add the egg to the dry mixture then add the wet mixture and beat until smooth.

Pour 50g into the tins about 2/3 full (you can use a piping bag) and bake for 15-18 minutes or until a cocktail stick comes out clean.

Transfer to a wire rack to cool.

For the frosting, beat the cream cheese and the butter together until pale and fluffy. Then gradually fold in the icing sugar until smooth. Add the maple syrup and beat until smooth.
