Preheat oven to 350 F.
Prepare a 9-inch cake pan.
Place the apples in a bowl.
Add brown sugar and lemon juice. Stir and set aside.
To prepare the cake, place Peetz Smart Blend in a medium bowl.
Whisk in baking powder, cinnamon and cardamon.
In the bowl of a stand mixer, fitted with a paddle attachment, beat the butter and sugar together for two minutes.
Add 1 egg and beat for 1 minute.
Scrape down the sides of the bowl with a spatula before adding each additional eggs one by one.
Add the Calvados and mix for 1 minute.
Add the dry ingredients and beat just until a batter forms.
Pour the batter into the prepared cake pan.
Place the apples on top of the cake in a circular formation, starting at the edge of the pan and working inward. Press down lightly.
Bake the cake for approximately 45 minutes, until golden brown and a toothpick inserted into the centre comes out clean.
Place cake on a wire baking rack to cool for 10 minutes, before unmolding.
