Best homemade toffee recipe

Gather your ingredients and measure them out.

Prepare your cooking equipment: a medium saucepan, spatula, candy thermometer, and an 8×8 inch baking pan lined with parchment paper.

Combine unsalted butter, granulated sugar, water, and a pinch of salt in the saucepan over medium heat until melted and smooth.

Increase heat to medium-high and bring to a boil without stirring, using a wet pastry brush to wash down sugar crystals on the sides. Cook until it reaches 300°F (150°C).

Remove from heat, stir in vanilla extract, and pour into the prepared baking pan. Allow to cool for 5 minutes.

Once cooled and set (about 1-2 hours), break into pieces and store in an airtight container.
