Baking Peach Upside-Down Cake is simple if you follow these clear steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease a 9-inch round cake pan with some of the butter.
2. Prepare Peaches: In a bowl, toss the sliced peaches with ¼ cup of brown sugar and set aside for about 10 minutes.
3. Make Topping: In a saucepan over medium heat, melt ½ cup of remaining butter. Add the other ½ cup of brown sugar, stirring until dissolved. Pour this mixture into the bottom of the prepared cake pan.
4. Arrange Peaches: Neatly arrange the sliced peaches on top of the caramelized sugar in the pan.
5. Mix Batter: In a separate bowl, cream together granulated sugar and 1/4 cup butter until light and fluffy. Add eggs and vanilla, mixing well.
6. Combine Dry Ingredients: In another bowl, mix the flour, baking powder, and salt. Gradually stir this into the butter mixture, alternating with milk. Mix until just combined.
7. Pour Batter: Carefully pour the batter over the arranged peaches in the cake pan, spreading it evenly.
8. Bake: Place the pan in the oven and bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
9. Cool: Once baked, let the cake cool in the pan for about 10-15 minutes. This allows the caramel to set slightly.
10. Invert Cake: Carefully run a knife around the edges to loosen it. Place a serving plate over the pan and flip it to release the cake onto the plate.
