Step 1: Prepare the Oven and Pan: Preheat oven to 350F (175C). Grease and flour a 9x13 inch baking pan to prevent sticking. Alternatively, use baking spray with flour. This ensures easy removal of the cake after baking.
Step 2: Combine Wet Ingredients: In a large mixing bowl, whisk together the melted butter, eggs, milk, and vanilla extract until well combined. Ensure the butter is not too hot when adding the eggs to prevent them from cooking.
Step 3: Incorporate Cake Mix: Add the yellow cake mix to the wet ingredients. Mix on low speed until just combined. Be careful not to overmix, as this can result in a tough cake. A few lumps are okay at this stage.
Step 4: Fold in Peaches: Gently fold in the drained peach slices into the batter. Distribute the peaches evenly throughout the mixture, ensuring each bite will have a taste of peach.
Step 5: Pour into Pan: Pour the batter into the prepared baking pan, spreading it evenly. If desired, sprinkle the top with granulated sugar and cinnamon for a caramelized crust.
Step 6: Bake: Bake in the preheated oven for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean. Monitor the cake closely during the last few minutes of baking to prevent over-browning.
Step 7: Cool and Serve: Let the cake cool in the pan for at least 15 minutes before slicing and serving. This allows the cake to set and makes it easier to cut. Serve warm or at room temperature.
Optional Tips:
- For a richer flavor, substitute buttermilk for the milk.
- Add 1/2 cup of chopped pecans or walnuts to the batter for added texture.
- For a topping, mix 1/2 cup flour, 1/4 cup sugar, and 1/4 cup cold butter, cut into small pieces, and crumble over the top before baking.
