Ingredients

  • ½ cup heavy whipping cream
  • ½ cup powdered monk fruit (or your preferred powdered sweetener)
  • 4.5 ounces chopped 90% cocoa chocolate (sugar-free chocolate chips can be substituted)
  • 2 ounces unsalted butter
  • 2 teaspoons vanilla extract

How to Make Keto Chocolate Fudge

  1. Heat and Dissolve: In a saucepan over medium heat, combine the heavy cream, powdered monk fruit, and vanilla extract. Stir until the sweetener is fully dissolved.
  2. Melt Chocolate: Add the chopped chocolate to the cream mixture, whisking constantly until about 60% melted.
  3. Incorporate Butter: Remove the saucepan from the heat and whisk in the butter until the chocolate is completely melted and smooth.
  4. Chill and Set: Pour the fudge mixture into a lined, heatproof dish. Refrigerate for at least 3 hours or until firm.
  5. Enjoy: Cut the fudge into 12 squares and savor the rich chocolatey goodness!

Tips and Variations

  • Keto Fudge with Cocoa Powder: For an even richer flavor, you can substitute 1/4 cup of unsweetened cocoa powder for some of the chocolate.
  • Keto Fudge with Dark Chocolate Chips: If you prefer a deeper, darker chocolate flavor, use sugar-free dark chocolate chips instead of 90% cocoa chocolate.
  • Storage: Store your keto fudge in an airtight container in the refrigerator for up to a week, or freeze for up to three months.

Frequently Asked Questions (FAQs)

Can I use a different sweetener?

Yes, you can use any powdered keto-friendly sweetener, such as erythritol or allulose. Adjust the amount according to your taste preferences and the sweetness of the sweetener.

Can I add nuts or other toppings?

Absolutely! Chopped nuts, shredded coconut, or a sprinkle of sea salt can add a delightful crunch and flavor to your keto fudge.
