Creating your own Brown Sugar Peach Cake is easy if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan or line it with parchment paper.
2. Mix Dry Ingredients: In a large bowl, combine the flour, brown sugar, granulated sugar, baking powder, baking soda, and salt. Whisk together until well blended.
3. Combine Wet Ingredients: In another bowl, mix the melted butter, eggs, and vanilla extract until thoroughly combined.
4. Fold Mixtures Together: Pour the wet mixture into the dry ingredients. Stir gently until just combined; be careful not to overmix.
5. Prepare Peaches: In a small bowl, toss the diced peaches with lemon juice and ground cinnamon (if using). Fold the peaches gently into the batter.
6. Transfer Batter: Pour the batter into the prepared cake pan, spreading it evenly.
7. Bake: Place the cake in the preheated oven and bake for about 40-45 minutes or until a toothpick inserted in the center comes out clean.
8. Cool the Cake: Once baked, remove the cake from the oven and allow to cool in the pan for 10-15 minutes. Then, transfer to a wire rack to cool completely.

These clear steps will guide you in creating this delicious and moist Brown Sugar Peach Cake effortlessly.
