Preparation Steps

• Preheat your oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
• In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
• Beat in the eggs one at a time, then stir in the vanilla extract.
• In a separate bowl, whisk together the flour, baking powder, and salt.
• Gradually add the dry ingredients to the wet ingredients, alternating with the milk, beginning and ending with the dry ingredients. Mix until just combined.
• Gently fold in the sliced peaches.
• In a medium bowl, combine the flour, brown sugar, granulated sugar, and cinnamon for the topping. Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
• Spread the cake batter evenly into the prepared baking pan. Sprinkle the crumb topping evenly over the batter.
• Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean and the topping is golden brown.
• Let the cake cool in the pan for at least 15 minutes before slicing and serving. Serve warm or at room temperature.
