The smell while cooking was delicious, thank you for this wonderful recipe, it was lovely, had to change the walnuts for chocolate chips as husband has a severe nut allergy but it worked fine !!! - 10 Feb 2013


This cake is really easy to make, especially in a mixer. It is lovely and moist but also quite crunchy - due to the oat walnut topping. Delicous. - 07 May 2013
