Preheat the oven to 350 F / 180 C and line a baking tray with baking paper.
Make Cinnamon Sugar Topping: In a small bowl, mix 1 teaspoon of cinnamon with 1 teaspoon of sugar and set aside.
Mix the Dry Ingredients: In a bowl, mix flour, baking powder, baking soda, ground cardamom, ground cinnamon and the remaining sugar until combined.
Add Butter: Using your fingertips, rub the cold butter into the mixture, leaving some chunks of butter to create the flaky texture that we seek.
Add Apple and Cream: Mix in the shredded apple and cream just until a dough forms (DON'T knead the dough).
Shape the Dough: Place the dough on a lightly floured surface and gently shape it with your hands into a circle, about 2 cm thick. Use a knife to divide the circle into 8 equal pieces.
Add Topping: Place them on the baking sheet and then scatter the cinnamon sugar mixture on top of each one.
Bake in the preheated oven for 15-20 minutes, or until golden brown. Serve warm.
Notes
