Notes and substitutions
- Brownie mix: Use a regular-size (about 18 ounces) boxed brownie.
- Water: Replace with milk, buttermilk, or brewed coffee to add richness and flavor.
- Instant coffee: An optional ingredient that enhances the chocolate flavor and tames the sweetness of the brownies.
Tips for best brownies
- Bring eggs to room temperature and lightly beat them to incorporate them well without overmixing.
- Grease and line the pan with parchment paper to prevent the brownies from sticking.
- To avoid overbaking, check brownies with a toothpick two minutes before they are done. Look for several separate crumbs for fudgy brownies and less for cakey brownies.
- Cool the brownies before slicing. Refrigerating them improves their texture.
