Line an 18cm square baking tin with greaseproof paper. Melt butter, golden syrup and sugar in a large pan.
Mix in rolled oats, carrots, orange zest, apricots, cinnamon and pumpkin seeds. Stir everything well, then pack into the prepared tin, pushing down firmly.
Bake for 40-45 mins, then cool in the tin before slicing into 16 squares.
