Ingredients
- Unsalted ButterUse high-quality butter, as its flavor serves as the necessary rich base, binding the marshmallows and cereal together firmly.
- MarshmallowsStandard size marshmallows are best here, providing the optimal ratio for melting into a gooey, binding cloud of sweetness.
- Crisped Rice CerealThe structural backbone of the treat, ensuring the necessary crunch that contrasts beautifully with the soft, gooey filling.
- Fresh Key Lime JuiceThis is non-negotiable; bottled lime juice simply lacks the required sharp, vibrant acidity and authentic flavor profile we are building.
- Key Lime ZestThe zest contains the essential oils that deliver the most concentrated citrus aroma and pungent flavor, making the treat truly sing.
- Vanilla PowderA small amount helps to deepen the overall sweetness and provide a comforting background note, balancing the strong lime presence.
- Green Food Coloring (Optional)Use a few drops of gel coloring to achieve the iconic pale green color associated with traditional Key Lime desserts.

Notes
- For optimal texture, store the cooled treats in an airtight container at room temperature for up to three days, as refrigeration tends to harden the marshmallow base too much.
- If the treats become too firm after resting, microwave a single square for just 5-7 seconds to restore a slight gooeyness without melting the structure entirely.
- Enhance the "pie" experience by drizzling the finished treats with a thin line of melted white chocolate or dusting them lightly with crushed graham crackers before serving.
- Incorporate the fresh Key Lime juice and zest only after the melted marshmallow is removed from the heat, as the acid can inhibit the treats from setting up firmly if added while boiling.
