So there are two ways to make the average fudge.. One is made by heating milk, butter and sugar to over 11 degrees before cooling and beating the mix until it’s thick. Another is melting chocolate into condensed milk and butter, then setting it aside to firm up.

I decided to go with the latter when making this low carb fudge. Keto condensed milk is super easy to make so I figured this would be a simple way to make a chocolate fudge.

When making condensed milk, it’s vital to keep an eye on it at all times otherwise it could burn easily. You want to bring the cream, butter, sugar and vanilla to a boil before turning it down to a simmer and let the water evaporate. That will leave the the thick fat behind but if you let it sit too long on the heat it could burn. So stir frequently.

Another note is that before you add the chocolate to the condensed cream, make sure you let it COOL. If the mixture is too hot, the chocolate will seize and it will look watery while the chocolate becomes tiny rice-like granuals. It’s not pretty, so rest the condensed cream for at least 15 minutes. The cream should be warm to the touch but not hot.



The fudge I made turned out fairly thin because I used a medium size pan for molding. If you want a thick fudge, I recommend using a smaller square pan.

If you want to make this dairy free – eliminate the butter and replace the heavy cream with coconut milk (same amount)!
