Preheat the oven to 350 degrees.
Prepare a 9” round cake pan with cooking oil and parchment paper.
In a medium bowl whisk together the flour, baking powder, cardamom, nutmeg, and salt.
Whisk together the 1/2 cup sugar, 1/2 cup brown sugar, honey, vanilla, milk, melted butter, and eggs in another bowl.
Whisk the egg mixture into the flour mixture.
In a small saucepan combine the remaining 1/2 cup sugar and 3 tbsp water and simmer for 5 minutes.
Stir in 5 tbsp butter and pour the hot mixture into the cake pan.
Decorate with even layers of apple wedges.
Spread the cake batter over the apples.
Bake for 35-40 minutes until the top is golden brown.
Let the cake cool for about 15 minutes. Then flip it onto a cake platter and remove the parchment paper.
