Scotch Toffee

These Scotch toffee bars are dead simple and dangerously good. Rolled oats mixed with melted butter, brown sugar, dark corn syrup, salt, and vanilla get packed firmly into a pan and baked at high heat until brown and bubbly. Once cooled, the base flips out in one piece, gets spread with melted chocolate, sprinkled with chopped nuts, and chilled until the chocolate sets.

The high oven temperature is what makes these work. Twelve minutes at 450°F (230°C) caramelizes the sugar and syrup quickly, turning the oat mixture into a chewy-crunchy toffee base. Any longer and they burn. Any cooler and they stay soft and crumbly.

Cut them into small bars. They’re rich and intensely sweet, so a little goes a long way. Store in the fridge to keep the chocolate firm.

Pro Tips

• Pack the oat mixture firmly and evenly into the pan. Loose packing means the bars crumble instead of holding together.
• Grease the pan well. The sugar mixture gets extremely sticky during baking, and a poorly greased pan means broken bars.
• Cool the base completely before inverting and topping with chocolate. Warm bars melt the chocolate too thin and it won’t set properly.
• Use a sharp knife to cut bars while the chocolate is still slightly soft. Fully set chocolate cracks and shatters when cut.

Variations

• Peanut butter layer: Spread a thin layer of peanut butter over the base before adding the melted chocolate.
• Sea salt finish: Sprinkle flaky sea salt over the wet chocolate for a sweet-salty contrast.
• White chocolate version: Use white chocolate chips instead of semisweet and top with dried cranberries for a festive look.
