Instructions:
Preheat Oven:
Preheat your oven to 375°F (190°C).
Grease a 9×13-inch baking pan or line it with parchment paper.
Prepare the Crust and Crumble:
In a large mixing bowl, stir together the melted butter, granulated sugar, brown sugar, and vanilla extract until well combined.
Add the baking powder, salt, and flour. Mix until a crumbly dough forms.
Press about two-thirds of the dough evenly into the bottom of the prepared baking pan to form the crust. Reserve the remaining dough for the crumble topping.
Prepare the Peach Filling:
In a medium bowl, combine the diced peaches, granulated sugar, cornstarch, lemon juice, and vanilla extract. Mix until the peaches are evenly coated.
Spread the peach mixture evenly over the crust in the baking pan.
Add the Crumble Topping:
Crumble the reserved dough evenly over the peach filling.
Bake the Bars:
Bake in the preheated oven for 45-50 minutes, or until the top is golden brown and the filling is bubbling.
Remove from the oven and let cool completely in the pan on a wire rack.
Prepare the Glaze:
In a small bowl, whisk together the powdered sugar, milk, and vanilla extract until smooth. Adjust the consistency by adding more milk if necessary.
Finish the Bars:
Once the bars are completely cool, drizzle the glaze over the top.
Cut into squares and serve.
