Key Lime Crack Recipe
Introduction
Key Lime Crack is a delightful, tangy twist on a classic sweet and salty snack mix. Combining crunchy cereal, pretzels, and marshmallows with zesty lime and creamy white chocolate, this treat is addictive and perfect for any occasion.

Ingredients
- 4 cups Cinnamon Toast Crunch (Golden Grahams or broken graham crackers work too)
- 2 cups pretzels
- 2 cups mini marshmallows
- 1 (11 oz) bag white chocolate chips
- 1 tablespoon coconut oil or vegetable oil
- 4 tablespoons lime zest (from about 2 limes)
- 2 tablespoons lime juice (from about 1/2 a lime)
Instructions
- Step 1: In a large mixing bowl, combine the Cinnamon Toast Crunch, pretzels, and mini marshmallows. Toss gently to mix, then set the bowl aside.
- Step 2: Place the white chocolate chips and coconut oil in a microwave-safe bowl. Microwave in 30-second intervals, stirring between, until the mixture is smooth and melted.
- Step 3: Stir 2 tablespoons of lime zest into the melted white chocolate until evenly incorporated.
- Step 4: Pour the white chocolate and lime zest mixture over the cereal, pretzel, and marshmallow mix. Use a spatula to gently fold and coat everything evenly with the chocolate.
- Step 5: Spread the coated mixture out in an even layer on a baking sheet lined with parchment paper or a silicone mat.
- Step 6: Sprinkle the top with the remaining lime zest and squeeze fresh lime juice over the surface.
- Step 7: Refrigerate the tray for about 20 minutes, or until the chocolate hardens. Once set, break into pieces and serve.
Tips & Variations
- For extra crunch, try substituting pretzels with salted nuts or adding toasted coconut flakes.
- If you prefer a more intense lime flavor, add additional zest or a small amount of lime extract to the melted chocolate.
- To make this treat nut-free, double-check that your cereal and pretzels are processed in a nut-free facility.
Storage
Store Key Lime Crack in an airtight container at room temperature for up to 3 days or refrigerate for up to a week. To keep the chocolate coating firm, refrigeration is recommended. If chilled, allow it to come to room temperature for a few minutes before serving for the best texture.

Can I use a different type of cereal?
Yes, you can substitute Cinnamon Toast Crunch with Golden Grahams, regular graham crackers, or other crunchy cereals that complement sweet and salty flavors well.
What if I don’t have coconut oil?
