Chef's Notes
TEXTURE TARGET: Crunchier than Fruity Pebbles bars. Distinct cereal squares, gooey binder, buttery, strong cinnamon aroma. The recipe should still clearly taste like Cinnamon Toast Crunch. Do not bury the cereal beneath excessive additional cinnamon. CHEF'S NOTES: • Brown butter adds warmth and depth. • Keep heat low when melting marshmallows to prevent hardening. • Cinnamon Toast Crunch squares should stay visibly intact — fold carefully. • Press very gently to preserve crunch. 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.
