Start by preheating your oven to 180°C (350°F) and greasing a 9-inch round cake tin with butter or lining it with parchment paper.
Next, peel, core, and thinly slice the apples. Toss them with a sprinkle of cinnamon to enhance the flavor. Set aside for later.
4 Medium apples
In a large mixing bowl, combine the wholemeal flour, baking powder, salt, and nutmeg or mixed spice.
225 g Wholemeal flour, 2 tsp Baking powder, Salt, 1 tsp Nutmeg or mixed spice
Next, add the light muscovado sugar, melted butter, and beaten eggs to the bowl. Stir well until all the ingredients are thoroughly combined and you have a smooth batter.
175 g Light muscovado sugar, 150 g Butter, 2 large Eggs
Pour half of the batter into the prepared cake tin, spreading it evenly with a spatula.
Arrange a layer of sliced apples on top of the batter, making sure to cover the entire surface. Sprinkle some cinnamon over the apples for an extra burst of flavor.
Repeat this process, adding the remaining batter and another layer of sliced apples with cinnamon.
To make the streusel topping, combine the demerara sugar and flaked almonds in a small bowl. Sprinkle this mixture over the top of the cake, evenly covering the apples and batter.
Demerara sugar, 2 tbsp Flaked almonds
Place the cake tin in the preheated oven and bake for approximately 45-50 minutes, or until a toothpick inserted into the center comes out clean.
