Follow these simple steps to create your very own Caramel Apple Upside Down Cake:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9-inch round cake pan.
2. Prepare the Caramel: In a saucepan over medium heat, melt ½ cup of butter. Stir in the brown sugar and cook until dissolved, about 2 minutes. Pour this mixture into the prepared cake pan.
3. Add Apples: Arrange the sliced apples over the caramel mixture in the pan. Sprinkle with cinnamon and set aside.
4. Mix Dry Ingredients: In a bowl, whisk together the flour, baking powder, and salt.
5. Cream Butter and Sugar: In a large mixing bowl, cream the remaining ½ cup of butter with granulated sugar until light and fluffy.
6. Add Eggs: Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next.
7. Combine Mixtures: Gradually add the dry ingredients to the butter mixture, alternating with the milk. Mix until just combined.
8. Pour Batter: Gently pour the cake batter over the arranged apples in the pan.
9. Bake: Bake in the preheated oven for 30-35 minutes or until a toothpick inserted in the center comes out clean.
10. Cool: Remove from the oven and let the cake cool in the pan for about 15 minutes.
11. Invert the Cake: Carefully run a knife around the edges. Place a serving plate over the cake pan and invert it to release the cake onto the plate, allowing the caramel and apples to be on top.
