Place all the ingredients in a pot and heat up over low heat. Stir to help melt the ingredients and combine them. The mixture will start developing a smooth and creamy texture.
Bring to a soft boil and simmer for 10 minutes. Stir continuously so it doesn't burn. Scrape the bottom of the pot to prevent the mixture from sticking to it.
If you are using a thermometer, the fudge should reach about 240-240ºF/115-120ºC. If you don't have a thermometer, spoon a small portion of the mixture over a bowl with ice water. You should be able to form a small ball that doesn't stick to your hands.
Remove from the heat and let it cool down for a few minutes. and whisk until it's thick. Chef's Tip: If you're using any other flavors or add-ins, it's best to add them now, before whisking.
Whisk the fudge until it's thick. Whisking it will allow it to cool down and thicken. Keep in mind that this might take up to 10 minutes - it should almost begin to set and will also lose its shine. The longer you whisk it, the more crumbly the fudge will be at the end.
Pour the mixture into a tray lined with parchment paper (8 inches/20 cm) and spread evenly. Then cover it with more parchment paper and let it cold down to room temperature before placing it in the fridge to chill and firm up.
Once the fudge is set, you can cut it into squares. I cut them into 1-1.5 inch cubes but you can cut them into your preferred size.
How to Store
Keep the fudge stored in an airtight container.You can keep it at room temperature for up to about 2 weeks or in the refrigerator for about 3 weeks.You can also freeze the fudge cubes - wrap each piece individually and then store them in an airtight container in the freezer for about 2 months. To thaw, just put it in the refrigerator.
Notes
Optional Add-insThis caramel fudge is absolutely great on its own, but feel free to include some of your favorite add-ins for added texture and flavor. Here are a few ideas:
If you're a peanut butter lover, you can add a few tablespoons of homemade peanut butter!
Nuts: You could add your favorite nuts or even roasted nuts or salted peanuts. Pecans and walnuts would be nice!
Chocolate chips or pieces of homemade chocolate are also a great addition to this caramel fudge.
