Keto Chocolate Fudge Recipe with Keystone Pantry Allulose

Yield: About 16 squares
Prep Time: 10 minutes
Cook Time: 10 minutes
Chill Time: 2–3 hours


Why This Recipe Works

Traditional fudge relies heavily on sugar for both sweetness and structure. This keto-friendly version uses Keystone Pantry Allulose, a rare sugar that tastes and behaves like traditional sugar but doesn’t impact blood glucose levels. Allulose caramelizes and melts like regular sugar, giving this fudge its smooth texture and classic rich taste—without the carbs.


Ingredients & Purpose

Fudge Base:

  • 1 cup heavy cream
    Provides richness and the creamy base that helps fudge set.

  • 1/2 cup Keystone Pantry Allulose
    Delivers the sweet taste and contributes to the classic fudge texture without affecting blood sugar.

  • 1/2 cup unsalted butter (1 stick)
    Adds creaminess and helps emulsify the ingredients.

  • 1/4 tsp sea salt
    Enhances the depth of chocolate flavor and balances the sweetness.

  • 1/2 cup Keystone Pantry sugar-free chocolate chips (allulose-sweetened)
    Gives deep cocoa flavor and melts beautifully into the fudge base.

  • 1/4 cup unsweetened cocoa powder
    Intensifies the chocolate flavor and contributes to structure.

  • 1 tsp vanilla extract
    Rounds out the flavor and gives a warm, aromatic finish.

Optional Add-ins:

  • 1/2 cup chopped pecans or walnuts
    For crunch and a nutty contrast to the smooth fudge.

  • Flaky sea salt (for topping)
    Adds a gourmet finish and complements the chocolate.


Instructions

  1. Prepare the Pan
    Line an 8×8-inch square baking dish with parchment paper, leaving some overhang on the sides for easy removal.

  2. Simmer the Base
    In a medium saucepan, combine the heavy cream, Keystone Pantry Allulose, butter, and salt over medium heat. Stir continuously until the mixture comes to a gentle simmer.

  3. Cook Until Thickened
    Let the mixture simmer gently for about 8–10 minutes, stirring often. You’re looking for a slightly thickened consistency and some light browning around the edges. Allulose will caramelize slightly, helping to create that classic fudge feel.

  4. Add Cocoa and Chocolate Chips
    Remove from heat and whisk in the cocoa powder until fully combined. Then stir in the Keystone Pantry chocolate chips until melted and smooth.

  5. Flavor & Optional Texture
    Stir in the vanilla extract. If using, fold in chopped nuts for texture.

  6. Pour and Chill
    Pour the mixture into the prepared pan. Smooth the top with a spatula. If desired, sprinkle flaky sea salt over the top.

  7. Refrigerate
    Chill for at least 2–3 hours, or until the fudge is firm enough to cut. For a firmer texture, you can chill overnight.

  8. Slice & Serve
    Lift the fudge from the pan using the parchment paper. Slice into 16 small squares. Store in an airtight container in the fridge for up to 2 weeks—or freeze for longer storage.

Tips for Success

  • Use a quality heavy cream — it makes a big difference in the texture.

  • Don’t boil too rapidly — a gentle simmer ensures the allulose doesn’t burn and the fats don’t separate.

  • Chill thoroughly — fudge needs proper time to set or it may be too soft to slice cleanly.


Serving Ideas

  • Cut into mini cubes and serve on a keto dessert platter.

  • Drizzle with melted sugar-free white chocolate for a swirl effect.
