Preheat convection oven to 180 degrees celcius
Line your cake tin with baking paper on the bottom and the edges, so nothing will stick
To make the frangipane-like disc:In a blender or food processor, grind the almonds and sugar into a crumb or flour-like consistency (use the s blade). While running, add in the amaretto until a stiff dough forms. Taste if you want some more sweetness. If so, add in more sugar.Create a disk or rectangular shape to fit your cake tin and set aside First beat the soft butter together with the sugar until it is nice and fluffy and has lightened in colour
Add in the eggs one by one and beat until incorporated
Add the flour, salt, cinnamon and baking powder and beat until well mixed
Now add a little splash of amaretto and the milk and mix until the consistency is smooth
Chop the almonds and stir them into the batter
Put a small layer of batter into the cake tin and if you are using the frangipane-like layer, place that on top
Add the rest of the batter and place the apple slices into a shape you like. Push them down a little and sprinkle some more chopped almonds on top
Put in the oven and bake for about 1 hour and 15 minutes. Check after one hour, if a skewer comes out clean it is done. If not, check every 15 minutes after that
When the cake is done let it cool a little, remove from the baking tin and let it cool completely on a baking/cooling rack
Meanwhile you can make the glaze by combining the icing sugar with the amaretto or almond flavouring and water. Just be careful to start with a little amaretto/water. You can always add more if needed. The consistency should be thick but pourable
When completely cooled, drizzle the glaze on top
Enjoy!
