Step 1

Heat oven to 180C/160C fan/gas 4 and line a 20 x 20 cm tin with baking parchment. Melt the butter, sugar and golden syrup in a pan until bubbling. Tip in the oats and stir until everything is well coated. Press ¾ into the tin, spread over the lemon curd then sprinkle over the remaining flapjack mix. Bake for 30 mins then leave to cool.

Step 2

Mix the icing sugar with the lemon juice then drizzle across the cooled flapjack and cut into 12 pieces.
