Creating your Peach Upside Down Cake is straightforward when you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9-inch round cake pan.

2. Prepare the Peaches: In a medium bowl, combine the sliced peaches with half of the brown sugar and set aside to macerate for about 10 minutes.

3. Make the Topping: In the prepared cake pan, mix the melted butter and remaining brown sugar until well combined. Spread this mixture evenly across the bottom of the pan.

4. Arrange the Peaches: Lay the macerated peach slices over the brown sugar mixture in a decorative pattern.

5. Mix Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.

6. Combine Wet Ingredients: In another bowl, beat the granulated sugar and eggs until fluffy. Add the vanilla extract and milk, mixing until smooth.

7. Combine Mixtures: Gradually stir the dry ingredients into the wet mixture until just combined. Be careful not to overmix.

8. Pour Batter: Gently pour the batter over the arranged peaches in the pan, spreading it evenly.

9. Bake: Place the pan in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.

10. Cool: Remove the cake from the oven and let it cool in the pan for about 15-20 minutes.

11. Invert the Cake: Carefully run a knife around the edges of the pan. Place a serving plate over the pan and invert it to release the cake, allowing the peach topping to be on top.

These steps will guide you in creating a beautiful and delicious Peach Upside Down Cake that will impress everyone at the table!
