Pour the flour, Tate & Lyle Pure Cane Caster Sugar, egg, milk, oil and lemon zest into a large, deep mug. Beat the mixture with a fork until smooth.
Spoon a generous dollop of Lyle’s Golden Syrup on to the centre of the batter and put the mug in the microwave.
Cook on high for 3 to 4 minutes, medium setting (600 watts) until the cake is firm to the touch. Careful though, it’ll be hot.
Allow to stand for one minute, then serve in the mug topped with a scoop of ice cream and a delicious drizzle of sticky Lyle’s Golden Syrup.
