Ingredients

Instructions

  1. Lightly grease and parchment-line a 9×9-inch pan.
  2. Place Frosted Flakes into a very large bowl so there is room to fold without crushing them.
  3. Brown butter gently until golden and aromatic.
  4. Reduce heat to low.
  5. Add marshmallows.
  6. Stir until just melted.
  7. Remove from heat.
  8. Stir in vanilla and sea salt.
  9. Pour over cereal.
  10. Using a large flexible spatula, FOLD rather than stir. Preserve as many intact flakes as practical.
  11. Transfer to pan.
  12. Spread into an even layer.
  13. Press extremely gently. Do NOT pack firmly.
  14. Allow to set approximately 45 minutes.
  15. Cut into 16 bars.
  16. OPTIONAL CHOCOLATE BOTTOM: After bars have set enough to lift, melt 3 oz chocolate gently, spread a very thin layer over the bottom surface, and allow chocolate to set before slicing completely.

Chef's Notes

TEXTURE TARGET: This should be the CRISPIEST of the four branded bars. Large visible flakes, light marshmallow coating, crisp bite, buttery vanilla finish. NOT: crushed cornflake brick, overly gooey, excessively sweet. CHEF'S NOTES: • Frosted Flakes are already sweet — do NOT add additional granulated sugar. • Use a very large bowl to give yourself room to fold. • Press extremely gently to preserve flake integrity. • The optional chocolate bottom is not part of the default recipe identity. STORAGE: Store airtight at room temperature. Best within 2–3 days. SCALING PAN GUIDANCE: • 0.5× (8 bars): 8×8-inch pan or loaf pan. • 1× (16 bars): 9×9-inch square pan. • 1.5× (24 bars): 9×13-inch pan or two pans. • 2× (32 bars): Two 9×9-inch pans.
