We have just moved into a rented house with an electric aga. Last weekend I made a gluten free cake with a new recipe. Ground almonds and mash potato. Preheated oven, lined tin checked 5 mins before due 45 mins at 180. It took much longer stopped at 1hr 5 as the bottom was burnt. Took burn base off and cake was lovely but still fractionally undercooked - I assume the aga was too hot so will try again at 170 but wondered if I just wasn't using the aga properly
