Jamie Oliver’s rolled carrot cake is a carrot-flavoured sponge baked flat, rolled while warm, then filled with cream cheese frosting once cooled.
It combines the flavour of traditional carrot cake with the appearance and structure of a roulade.
For the carrot sponge
For the cream cheese filling
Preheat the oven to 180°C (160°C fan). Line a shallow rectangular baking tray with baking paper, leaving a slight overhang on the sides.
Whisk the eggs and sugar together until pale and slightly thickened. Slowly whisk in the oil until smooth, then fold in the grated carrots, orange zest, and spices.
Sift in the flour and baking powder. Fold gently until just combined, taking care not to knock out too much air.
Spread the batter evenly in the prepared tray. Bake for 12–15 minutes, until the sponge springs back lightly when touched.
Turn the sponge out onto a clean sheet of baking paper. Peel away the lining paper, then gently roll the sponge from the short side while it is still warm. Leave it rolled until completely cool.
Beat the cream cheese, butter, icing sugar, and vanilla until smooth and creamy.
Carefully unroll the cooled sponge, spread the filling evenly over the surface, then roll it back up gently. Chill briefly before slicing.
