Measure all ingredients into a thick bottom kettle. Heat up and stir the mixture for about 60-70 minutes until the mixture thickens. Remove the vanilla stick.

Cover a low dish with parchment paper and pour the mixture in the dish. Let the mixture cool in the fridge. Cut the hardened toffee into squares and enjoy!

Instead of sugar+vanilla stick you can also use homemade vanilla sugar.

You can replace vanilla with cardamom and cinnamon and make toffee that tastes like cinnamon buns.
