Creating Fresh Peach Cobbler with Buttery Biscuit Topping is simple when you follow these steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Peaches: In a large bowl, combine the sliced peaches, 1/2 cup of the sugar, lemon juice, vanilla extract, cornstarch, cinnamon, and salt. Toss until the peaches are well coated.
3. Transfer to Baking Dish: Pour the peach mixture into a greased 9×13-inch baking dish, spreading it evenly.
4. Make the Biscuit Topping: In a separate bowl, whisk together the flour, remaining 1/2 cup of sugar, and baking powder.
5. Cut in Butter: Add the cold, cubed butter to the flour mixture. Use a pastry cutter or your fingers to mix until it resembles coarse crumbs.
6. Add Milk: Stir in the milk until just combined; the dough will be slightly sticky.
7. Drop Biscuit Topping: Using a spoon or cookie scoop, drop spoonfuls of the biscuit mixture over the peach filling. It doesn’t have to cover completely; some gaps will allow the peach juices to bubble up.
8. Brush with Egg Wash: Brush the tops of the biscuits with the beaten egg for a golden finish.
9. Bake: Place in the preheated oven and bake for 30-35 minutes, or until the biscuit topping is golden brown and the peach filling is bubbly.
10. Cool: Remove from the oven and let it cool for about 10 minutes before serving.
