UPDATE:  Adding some crushed peanuts to the mixture gives great texture to this fudge.  My husband loves that.  I'll make it again and figure out just how much to use - but probably about 1/3 cup crushed peanuts. :)

If you don't have cocoa butter, I'm guessing replacing it with 60 g (2 squares) unsweetened baker's chocolate should work.  Increase the sweetness level to taste.  The erythritol will need to be doubled at the very least.

This confection is so high in fat that it would make a great addition to the menu for a Fat Fast as outlined in the Atkins New Diet Revolution book.  Fantastic flavor and texture!  Now you know what to do with all those roasted peanuts.  Sadly, though I can't make this recipe anymore due to the preservatives in those particular peanuts.  As one gets older, certain foods become off limits.  If you are young, enjoy the benefits of being able to eat and drink whatever you would like, except of course high-carb junk food!  No one should be eating that!

3 cups roasted, salted peanuts (750 mL)
1/4 cup melted cocoa butter (be careful - it's super-hot!) (60 mL)
1/3 cup powdered erythritol (75 mL)
Granular sweetener to equal 2 tbsp sugar (30 mL)
2 tbsp powdered milk (30 mL)
2 tbsp vanilla whey protein (30 mL)
1 tsp vanilla extract (5 mL)

In food processor with metal blade, process peanuts well.  Add cocoa butter; process.  Add powdered erythritol, granular sweetener, powdered milk, vanilla whey protein and vanilla extract.  Process until smooth.  Pour into 8-inch (30 cm) square glass baking dish.  Smooth surface with back of spoon.  Keep in the freezer.  

Helpful Hints:  This fudge will cut fairly easily straight out of the freezer, but will begin to soften at room temperature quite quickly.  Do use oven mitts when removing the cocoa butter from the microwave oven, if using, to melt the cocoa butter.  Practice extreme caution as it will be very hot.  It safer to let it cool down a bit before removing from the microwave oven or a double boiler.  Just be super-careful.
