Buttercrunch Toffee, often craved for its irresistible crunch and buttery richness, is a classic treat that evokes nostalgia and comfort. This homemade version, reminiscent of the beloved Heath Bar, is not only delectable but also surprisingly simple to make. With a few quality ingredients and a little patience, you can whip up a batch that rivals any store-bought candy. Let’s dive into this sweet adventure that’s guaranteed to impress family and friends alike.
Why It Works Every Time

The beauty of Buttercrunch Toffee lies in its straightforward method and foolproof ingredients. The key to a perfect toffee is bringing the sugar to the right temperature, allowing it to caramelize beautifully without burning. The combination of butter and sugar creates a rich, creamy base, while the chocolate and nuts add texture and flavor. The result is a treat that’s crunchy, sweet, and utterly addictive.
Ingredient Rundown

- 1.5 cups unsalted butter: The foundation of the toffee, giving it a rich flavor and creamy texture.
- 1.5 cups granulated sugar: This sweetener caramelizes to create that signature toffee flavor.
- 1.5 tablespoons light corn syrup: Prevents crystallization, ensuring your toffee is smooth.
- 1/2 cup water: Assists in cooking the sugar evenly.
- 10 ounces mini semisweet chocolate chips: I recommend Ghirardelli for its smooth melting quality and rich flavor.
- 1/2 cup finely chopped roasted almonds or pecans: For a delightful crunch. I prefer Trader Joe’s roasted & salted pecans.
- 1 to 2 teaspoons Maldon sea salt flakes: Adds a touch of savory contrast to the sweetness.
Recommended Tools

- Heavy-bottomed saucepan: Essential for even heat distribution when cooking the sugar.
- Candy thermometer: Crucial for monitoring the sugar’s temperature for perfect caramelization.
- Silicone spatula: Ideal for stirring and scraping down the sides of the pan.
- Baking sheet lined with parchment paper: Prevents sticking and allows for easy cooling.
- Measuring cups and spoons: Ensure accurate measurements for consistent results.
Buttercrunch Toffee (Homemade Heath Bar) Cooking Guide
Step 1: Prepare Your Workspace
Start by gathering all your ingredients and tools. Line a baking sheet with parchment paper and set it aside. This will be where your toffee cools and sets.
Step 2: Combine Ingredients in a Saucepan
In a heavy-bottomed saucepan, combine 1.5 cups of unsalted butter, 1.5 cups of granulated sugar, 1.5 tablespoons of light corn syrup, and 1/2 cup of water. Stir the mixture over medium heat until the butter melts and the sugar dissolves.
Step 3: Bring to a Boil
Once the mixture is smooth, increase the heat and bring it to a boil without stirring. Attach your candy thermometer to the side of the pan, ensuring it doesn’t touch the bottom. You’ll want to monitor the temperature closely.
Step 4: Cook to Hard Crack Stage
Continue cooking the mixture, swirling the pan occasionally, until the thermometer reads 300°F (hard crack stage). This process usually takes about 15 to 20 minutes. Keep a close eye to prevent burning.
Step 5: Pour onto Parchment Paper
Once you’ve reached the desired temperature, immediately pour the toffee mixture onto the prepared baking sheet. Use the spatula to spread it out evenly if necessary.
Step 6: Add Chocolate Chips
Allow the toffee to cool for about 5 minutes, then sprinkle the 10 ounces of mini semisweet chocolate chips over the top. Let them sit for a few minutes to soften.
Step 7: Spread the Chocolate
Once the chocolate has melted slightly, use a spatula to spread it evenly over the toffee. This creates a delicious chocolate layer that complements the buttery toffee.
Step 8: Top with Nuts and Sea Salt
Sprinkle the finely chopped roasted almonds or pecans over the chocolate layer. Finish by sprinkling 1 to 2 teaspoons of Maldon sea salt flakes on top for that perfect sweet and salty balance.
Step 9: Cool Completely
Let the toffee cool at room temperature until fully set, usually about 1 to 2 hours. If you’re in a hurry, you can place it in the refrigerator to speed up the process.
Step 10: Break and Serve
Once cooled, break the toffee into pieces using your hands or a knife. Serve it as a sweet treat, or package it up for gifts.
In-Season Flavor Ideas
- Chocolate Mint: Add a few drops of peppermint extract to the chocolate for a refreshing twist.
- Spiced Pumpkin: Incorporate pumpkin pie spice into the toffee mixture for a fall-inspired flavor.
- Coconut Delight: Mix in toasted coconut before pouring the toffee onto the baking sheet.
- Maple Pecan: Substitute maple syrup for corn syrup and use chopped pecans for a seasonal flavor.
Notes on Ingredients
When making Buttercrunch Toffee, the quality of your ingredients makes a significant difference. Choose unsalted butter for a cleaner flavor, and opt for high-quality chocolate chips to ensure a smooth melting process. The type of nuts you use can also change the flavor profile, so feel free to experiment with your favorites.
Best Ways to Store
To keep your Buttercrunch Toffee fresh, store it in an airtight container at room temperature. It can last for up to two weeks, though it’s unlikely to last that long! If you prefer to keep it for a more extended period, consider freezing it. Just ensure it’s well-wrapped to prevent freezer burn.
Ask the Chef
Can I use salted butter instead of unsalted?
While you can use salted butter, it’s best to stick with unsalted to control the saltiness of the toffee. You can always add the Maldon sea salt flakes to taste later on.
What if I don’t have a candy thermometer?
If you don’t have a candy thermometer, you can test the toffee by dropping a small amount into cold water. If it forms a hard ball, it’s ready; if it dissolves, it needs more cooking.
Can I make this toffee without corn syrup?
Yes! You can substitute corn syrup with honey or agave syrup. Just keep in mind that this may slightly alter the flavor and texture.
How do I fix grainy toffee?
If your toffee turns out grainy, it may have crystallized. To avoid this, ensure all sugar is dissolved before boiling, and avoid stirring the mixture once it starts boiling.
