Spicy Cinder Toffee

Pinterest Hidden Image

Our spicy cinder toffee recipe is a sugary treat with crunch and chew, with (as the recipe stands) just a hint of spiciness from cayenne pepper powder and a touch of warmth from cinnamon. This is a delicious holiday treat. It’s great for parties and festive gatherings, and it makes a terrific gift for your sweet-toothed friends. Simply pop some in a jar with a bow on top.

As mentioned, this recipe is mild enough for everyone to enjoy, but you can crank up the “spicy” in spicy cinder toffee by just increasing the amount of cayenne pepper used. Doubling it really raises the heat stakes in this sweet, but we’d suggest starting with just a pinch more to start.

If you’re planning on making this for a party (or as a gift), you’ll want to make a bigger batch by simply doubling or even quadrupling the mixture. If you do, make sure you have a large enough pot as the mixture expands rapidly when the bicarbonate of soda is added. A “too small” pot can leave quite a mess. Plan accordingly.

Spicy cinder toffee doesn’t keep for long, but something as delicious as this really never needs to keep for more than a few days. Your best bet is to keep it refrigerated in an airtight container and the toffee will last for up to five days.
