Critical Success Points

  • Melt butter without browning.
  • Combine wet and dry ingredients only until just mixed.
  • Bake for the full 30 minutes; under‑baking leads to soggy brownies.
  • Heat chocolate glaze gently to avoid seizing.
  • Allow the glaze to set in the refrigerator before slicing.

Safety Warnings

  • Melted butter and hot chocolate glaze are very hot; handle with care to avoid burns.
  • Use oven mitts when removing the pan from the oven.
  • Microwave‑safe bowl must be labeled microwave‑safe to prevent cracking.
