Here’s how to create an amazing Peach Cake with Brown Sugar Frosting:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

2. Mix Dry Ingredients: In a medium bowl, sift together the flour, baking powder, and salt. Set aside.

3. Cream Butter and Sugar: In a large mixing bowl, cream the softened butter and granulated sugar together until light and fluffy.

4. Add Eggs and Vanilla: Beat in the eggs one at a time, then add the vanilla extract, mixing until fully combined.

5. Combine Ingredients: Gradually add the dry ingredient mixture to the wet ingredients, alternating with the milk. Begin and end with the flour mixture, mixing until just combined.

6. Fold in Peaches: Gently fold in the diced peaches, ensuring even distribution without overmixing.

7. Divide Batter: Evenly pour the batter into the prepared cake pans.

8. Bake: Place the pans in the preheated oven and bake for 30-40 minutes. A toothpick inserted into the center should come out clean.

9. Cool the Cakes: Once baked, remove the cakes from the oven and let them cool in the pans for 15 minutes. Then transfer them to wire racks to cool completely.

10. Prepare Frosting: In a saucepan, melt the butter and brown sugar together over medium heat, stirring constantly until smooth. Add the milk and bring to a boil. Remove from heat and let it cool slightly.

11. Whip Frosting: Transfer the mixture to a mixing bowl and gradually add the powdered sugar, mixing until you achieve a smooth consistency. Add vanilla extract and beat until fluffy.

12. Assemble the Cake: Place one cake layer on a serving platter. Spread a thin layer of brown sugar frosting on top. Place the second layer on top and frost the top and sides of the cake.

13. Decorate: Optionally, garnish the top with additional diced peaches or a sprinkle of nuts for an extra touch.

These steps will guide you through the process of making an incredible Peach Cake with Brown Sugar Frosting effortlessly and deliciously.
