Peel and discard the core of the apples. Cut them into smaller pieces and mix them into the cake batter.
1.1 pound Apples
Butter your mold well, pour the batter into the prepared mold and spread evenly. Pour 2 Tablespoons of Calvados over the cake batter and finish by sprinkling the brown sugar over the cake.
Butter, 2 Tablespoons Calvados, 2 Tablespoons Brown Sugar
Bake for about 30 minutes at 350 Fahrenheit/ 180 Celsius until golden brown on top. Test with a knife, if the cake is baked, by poking into the center. If it's gooey keep for 5 more minutes to bake. The knife should come back clean.
Best served and enjoyed with a scoop of Vanilla ice cream or whipped cream.
You can substitute calvados with apple brandy or apple juice. Or skip it (but you will miss some flavors)
