Notes: Cake can also be sweetened with dates by simmering dates in water until they are quite mushy and most of the water has been absorbed. I would use between 150-200g dates. Adjust baking powder to 1/2t if you use self-raising flour, and use whatever flour you prefer. Sour milk can be made by adding 1T vinegar or lemon juice to sweet milk.
Optional additions: raisins, sultanas or berries.
Combine butter and honey. Add eggs. Stir in vanilla, baking powder, and cinnamon, until well combined.
Alternate milk and flours, stirring each time until well combined.
Stir in apples and any other additions.
Bake in round or square baking tin at 175°C/350°F for about 30 minutes. Cake will be firm to the touch and a toothpick should come out clean.
