Imagine the crispy, buttery snap of perfect homemade toffee, then enrobe it in the warm, comforting flavor of a cinnamon-sugar churro. That’s the magic of Churro Toffee. This irresistible candy combines a foolproof, crunchy toffee base with a generous coating of cinnamon-infused sugar and a final flourish of chocolate drizzle.
It’s a textural dream: the hard caramel crunch gives way to a melt-in-your-mouth sweetness, with the cinnamon providing a nostalgic, spiced warmth.

Break it into rustic shards for a stunning holiday gift box, or keep a batch for yourself to satisfy every sweet-salty-crunchy craving.
The Science of Snappy, Non-Grainy Toffee
Great toffee hinges on two scientific principles: proper sugar crystallization control and precise temperature. Toffee is essentially a caramelized sugar structure held together by butterfat. The enemy is unwanted sugar crystallization, which makes toffee grainy instead of glassy-smooth. This recipe uses a classic safeguard: incorporating a tablespoon of corn syrup and a splash of water at the start. These “interfering agents” prevent the sucrose molecules from locking into crystals too early.
Cooking the mixture to the hard crack stage (300-310°F / 149-154°C) is non-negotiable. This high temperature drives off almost all water, resulting in a hard, snappy texture once cooled. Adding baking soda at the end (a signature move for “buttercrunch”-style toffee) creates tiny bubbles as it reacts with the acid in the butter, yielding a slightly porous, lighter crunch that’s perfect for holding the cinnamon sugar coating.
Ingredients
For the Toffee Base:
- 1 cup (2 sticks / 226g) unsalted butter
- 1 cup (200g) granulated sugar
- 3 tablespoons water
- 1 tablespoon light corn syrup
- ½ teaspoon salt
- 1 teaspoon pure vanilla extract
- ¼ teaspoon baking soda
For the Cinnamon Sugar Coating:
- ½ cup (100g) granulated sugar
- 1 ½ tablespoons ground cinnamon
For the Chocolate Drizzle (Optional):
- ½ cup (85g) semi-sweet or dark chocolate chips
- ½ cup (85g) white chocolate chips
- ½ teaspoon coconut oil or shortening (divided)
Instructions
1. Prep & Mix Coating: Line a 9×13 inch baking sheet with parchment paper. In a small bowl, thoroughly mix the ½ cup sugar and cinnamon for the coating; set aside.
2. Cook the Toffee: In a medium, heavy-bottomed saucepan, combine butter, 1 cup sugar, water, corn syrup, and salt. Cook over medium heat, stirring constantly with a wooden spoon or heatproof spatula until the butter melts and the mixture comes to a boil.

3. Cook to Hard Crack: Once boiling, insert a candy thermometer. Continue cooking, stirring frequently, until the mixture reaches 300°F (149°C) – the hard crack stage. This will take 10-15 minutes. The toffee will be a deep golden amber color. Immediately remove from heat.

4. Aerate & Pour: Working quickly, stir in the vanilla extract and then the baking soda. The mixture will foam and become slightly paler. Immediately pour onto the prepared baking sheet. Tilt the pan or use an offset spatula to spread it into a thin, even layer.

5. Apply Cinnamon Sugar: Let the toffee cool for just 1 minute (it should still be very hot). Generously and evenly sprinkle about three-quarters of the cinnamon sugar mixture over the entire surface, pressing it gently with the back of a spoon so it adheres as the toffee sets.

6. Cool & Flip: Let the toffee cool completely at room temperature until hard, about 1 hour. Once hard, flip the entire slab over (using the parchment as a handle) onto a cutting board. Peel off the parchment and sprinkle the remaining cinnamon sugar over the second side.
7. Drizzle Chocolate: Melt dark and white chocolate chips separately with a little coconut oil. Using a fork or a small piping bag, drizzle the chocolates back and forth over the toffee slab. Let set for 15 minutes.
8. Break & Store: Once chocolate is set, break the toffee into bite-sized pieces with your hands or a knife. Store in an airtight container at room temperature for up to 2 weeks.

Pro-Tips for Foolproof, Professional Churro Toffee
- Heavy-Bottomed Pot is Essential: This ensures even heat distribution and prevents scorching.
- Patience with Temperature: Do not rush the cooking process or turn the heat too high. Let it come to 300°F steadily. If you don’t have a thermometer, test by dropping a bit into ice water; it should form hard, brittle threads that snap.
- Timing the Sugar Sprinkle: Sprinkling the cinnamon sugar when the toffee is just cool enough to not melt the sugar, but still hot enough for it to stick, is the key to a perfect coat.
- Humidity is the Enemy: Avoid making toffee on rainy or very humid days, as it can prevent it from setting properly and make it sticky.
- Customize It: Add a handful of finely chopped toasted almonds to the toffee right after pouring. Swap the chocolate drizzle for melted cinnamon chips.
This Churro Toffee is more than candy—it’s a crunchy, festive experience that will have everyone asking for the recipe.
