Preheat the oven to 180°C (350°F). Line the bottom of a springform pan with parchment paper and butter the sides.
Make the caramel layer: Sprinkle brown sugar over the parchment and place the pan in the oven for 15 minutes until the sugar caramelizes. Remove and let cool slightly.
Cream the butter and sugar in a bowl until light and fluffy.
Add the egg and beat until fully incorporated.
Mix in the ricotta cheese and continue beating until smooth.
In a separate bowl, combine the flour, baking powder, vanilla, cardamom, salt, and lemon zest.
Add the dry ingredients to the ricotta mixture and mix until a dense dough forms.
Slice the pears into thin wedges.
Layer cubed butter over the cooled caramel. Arrange the pear slices in a circular pattern like a fan.
Spread the batter gently over the pears. Use a spatula or damp hands to smooth the top.
Bake for 60 minutes or until a toothpick inserted comes out clean.
Let it cool for 10–15 minutes. Cover with a large plate and flip the cake carefully. Remove the parchment.
Slice, serve, and enjoy this golden, fragrant treat! 🍐
