Pro Tips for Perfect Lunch Lady Brownies
- Use room-temperature eggs: They blend in smoother and help create that tender texture.
- Don’t overmix after adding flour: Overmixing can lead to tougher brownies instead of the desired fudgy chew.
- Bake until the surface is matte and bubbly: That signals a perfect doneness — not underbaked and not dry.
- Frost while warm: Spread the chocolate frosting immediately after the brownies come out of the oven so it melts in slightly for a soft, glossy finish.
- Allow full cooling before slicing: Cooling ensures clean cuts and prevents the frosting from sliding.
- Sprinkle generously: Rainbow sprinkles add fun and festive flair — perfect for sharing or special occasions.
