Freshly baked toffee crackers covered with melting chocolate chips
Remove the pan from the oven and immediately sprinkle the chocolate chips in an even layer over the hot toffee-covered crackers. Let them sit for 2–3 minutes so the residual heat melts the chocolate.
Using an offset spatula or the back of a spoon, gently spread the softened chocolate into a smooth, even layer over the toffee and crackers, reaching all the way to the corners of the pan.
Allow the pan to cool at room temperature until it is no longer hot, then transfer it to the refrigerator and chill for at least 1–2 hours, or until the chocolate is fully set and the toffee is firm.

Once firm, lift the foil or parchment to remove the slab from the pan. Break the sweet into irregular pieces with your hands or cut into neat squares with a sharp knife.
Store the pieces in an airtight container at cool room temperature for up to 5 days, or in the refrigerator if your kitchen is warm and the chocolate seems soft.
Variations & Tips
For a more explicit Cinco de Mayo twist, sprinkle 1 teaspoon of ground cinnamon over the melted chocolate before it sets, or add a light dusting of chili powder for a subtle sweet heat. You can also finish the top with a small pinch of flaky sea salt for contrast, or add 1/2 cup of chopped toasted pecans, almonds, or pepitas over the melted chocolate for texture.

If you prefer darker chocolate, swap the semi-sweet chips for bittersweet; for a milder, kid-friendly version, use milk chocolate chips. To keep the recipe gluten-free, use a gluten-free saltine-style cracker and verify that your chocolate chips are certified gluten-free.
When working with the hot butter–sugar mixture, use a saucepan with high sides and a long-handled spoon to prevent splatters, and avoid touching the caramel directly—it can cause serious burns. Always let the toffee cool completely before breaking it, and store it away from direct sun or heat to prevent the chocolate from softening and separating.
