Preheat the oven to 180°C, Gas Mark 4. Grease and base line a 20cm round loose-bottomed cake tin.
Melt 100g butter with the honey and add the oats.
Mix together the oatmeal, sugar and flour in a large bowl. Melt the remaining butter and stir into the dry ingredients with the eggs. Pour into the cake tin.
Sprinkle the oat and honey mixture on top and bake for 45-50 minutes or until golden and a skewer inserted comes out clean.
Serve warm with a drizzle of honey.
Try adding some chopped walnuts to the oat topping for an extra crunchy texture.
This recipe is very indulgent so shouldn't be eaten too often, but it's perfect for those special occasions!
