This 4-ingredient oven baked Cinco de Mayo sweet is my quick, almost effortless answer to a last-minute dessert. It leans on a Midwestern pantry staple—dry, uncrushed saltine crackers—to create a crisp, candy-like base that gets drenched in a brown sugar–butter toffee and finished with melted chocolate.
While saltine “crack” toffee has roots in American home baking, here we nod to Cinco de Mayo with a sprinkle of cinnamon for warm, Mexican-inspired flavor. The result is a pan of glossy, crackly bites so addictive your friends will absolutely be reaching for seconds.

Serve the sweet broken into irregular pieces on a platter alongside fresh berries or sliced mango for a bright contrast. It pairs beautifully with coffee, Mexican hot chocolate, or a small scoop of vanilla or cinnamon ice cream.
For a more festive Cinco de Mayo spread, tuck pieces into a dessert board with churros, fresh fruit, and a bowl of whipped cream, and let everyone help themselves.
Cinco de Mayo Saltine Toffee Sweet
Servings: 12

Ingredients
1 sleeve (about 35–40) dry uncrushed saltine crackers
1 cup (2 sticks / 226 g) unsalted butter
1 cup (200 g) packed light brown sugar
1 1/2 cups (255 g) semi-sweet chocolate chips
Directions
Preheat your oven to 400°F (200°C). Line a metal sheet pan (roughly 10×15 inches) with foil or parchment, then lightly grease it to help with later removal.

Arrange the dry, uncrushed saltine crackers in a single, tight layer on the prepared sheet pan. The crackers should cover the pan completely with minimal gaps; break a few crackers only if needed to fit the edges.
In a medium saucepan over medium heat, combine the butter and brown sugar. Stir continuously as the butter melts and the sugar dissolves. Once it comes to a full bubble, let it cook, stirring, for about 3 minutes until the mixture looks thickened and glossy like a loose caramel.

Carefully pour the hot butter–brown sugar mixture evenly over the saltine crackers, using a heatproof spatula to gently nudge it so all crackers are coated. Work quickly so the toffee doesn’t set in one spot.
Place the sheet pan in the preheated oven and bake for 5–7 minutes, or until the toffee layer is bubbling vigorously across the entire surface and darkened slightly in color. Watch closely near the end to avoid burning.

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
