These crispy brown butter peach crumble bars feature a buttery, golden crust with a gooey peach filling, perfect for a quick and easy homemade dessert that balances crisp texture with juicy fruit flavor.
If the crumble browns too fast, tent loosely with foil halfway through baking. Add up to 1 tbsp extra cornstarch if peaches are very juicy to prevent soggy bars. Brown butter carefully on medium heat and remove immediately when nutty aroma appears to avoid burning. Peeling peaches can be easier by blanching in boiling water for 30 seconds then plunging into ice water. Cool bars completely before slicing for clean cuts.
