To prepare the base
Grease and flour the sides of an 8 inch cake tin then line the bottom with baking parchment. Roughly smear the parchment with the butter and sprinkle the sugar over the butter. Cut the plums in half lengthways and remove the stones then place cut side down over the base of the cake tin so they are touching. Set aside while you make the cake.
To make the cake batter
In a bowl mix the flour, ground and chopped walnuts, masala and baking powder together to get rid of any clumps of ground walnut. Set aside.
In a separate large bowl cream the sugar and butter together until light and fluffy. Add the beaten eggs a tablespoon at a time, making sure the eggs are well mixed in before adding the next tablespoon of egg. Once all the eggs have been incorporated into the butter mixture, mix 2 tablespoons of the flour mixture to stop the eggs from separating and add the milk. Fold all the remaining dry ingredients into the butter and eggs. Pour the batter into the prepared tin making sure to cover all the plums.
Bake for 40 minutes. Appliances vary so check after 30 minutes but don't worry if it takes longer than 40 minutes. To check if it's cooked, gently touch the centre top of the cake, any dent left by your finger will spring back if the cake is done, if your cake top is looking too dark before it’s cooked, cover the top loosely with a piece of baking parchment. Allow the cake to cool in the tin before turning out on to a plate and drizzle with a little honey while it's still slightly warm.
