Creating your Peach Melba Cake can be simple by following these easy steps:

1. Preheat your oven to 350°F (175°C) and prepare two 9-inch round cake pans by greasing and flouring them.
2. Mix the Dry Ingredients: In a large bowl, whisk together the flour, baking powder, and salt until well combined.
3. Cream the Butter and Sugar: In another bowl, cream together the softened butter and granulated sugar until light and fluffy.
4. Add Eggs and Vanilla: Beat in the eggs one at a time, mixing well after each addition. Then, add the vanilla extract and mix until combined.
5. Combine Wet and Dry Ingredients: Gradually add the dry ingredient mixture to the creamed butter and sugar, alternating with the milk. Mix until the batter is smooth and well incorporated.
6. Pour the Batter: Divide the batter evenly between the prepared cake pans and smooth the tops.
7. Bake: Place the pans in the preheated oven and bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
8. Cool the Cakes: Once baked, remove the cakes from the oven and let them cool in the pans for 10 minutes. Then, transfer them to wire racks to cool completely.
9. Prepare the Whipped Cream: In a mixing bowl, whip the heavy cream with powdered sugar until stiff peaks form.
10. Assemble the Cake: Once the cakes are completely cool, place one layer on a serving platter. Spread a layer of whipped cream on top, then layer with sliced peaches. Add the second cake layer on top.
11. Finish with Whipped Cream: Spread whipped cream over the top and sides of the cake, and decorate with additional peach slices and mint leaves if desired.

These clear steps will lead you to create this amazing Peach Melba Cake effortlessly.
