Prepare a small 9-inch x 6-inch casserole dish by layering the inside with
parchment paper, leaving enough parchment paper hanging over the sides of the
dish so you can remove the toffee once it eventually cools.
Set the prepared casserole dish aside for later.
Lightly toast the hazelnuts in a dry sauté pan until they are aromatic but haven’t
taken on much color.
Remove the nuts from the heat, and roughly chop them up.
Set the chopped hazelnuts aside for later.
In a small sauce pot, add the cubed salted butter, along with the white granulated
sugar.
Increase the heat to medium, and cook while stirring until the sugar has fully
melted.
Insert a candy thermometer into the mixture, and continue to cook while stirring
and scraping down the sides of the pot until the mixture reaches a temperature of
300˚F.
*The caramel should be lightly golden in color at this point.
Remove the caramel from the heat, and carefully pour in the vanilla and almond
extract.
*Note that your toffee mixture will make a loud noise when you add the liquid
extracts—don’t be alarmed!
Carefully pour the very hot caramel into your prepared casserole dish that is lined
with parchment paper.
Use an offset spatula to even out the caramel as best you can.
Evenly sprinkle the chocolate chips across the surface of the hot caramel, and wait
for two minutes for the chocolate chips to melt.
Use a clean offset spatula to gently spread the melted chocolate chips over the
surface of the caramel.
*Don’t worry if you don’t get this perfect, it tastes great even if you have some
sections with a bit more or less chocolate.
Sprinkle the chopped hazelnuts on top of the melted chocolate, and gently press the
nuts down into the chocolate so they stick to the surface.
Sprinkle a dainty pinch of Maldon Sea Salt on top.
Allow your Homemade Toffee with Chocolate and Hazelnuts to cool down in the
fridge for at least three hours before removing from the casserole dish and breaking
into pieces.
Serve whenever you like, and store the remainder in an airtight container.
