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
-
Prepare the Pan
Line an 8×8-inch square baking dish with parchment paper, leaving some overhang on the sides for easy removal. -
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. -
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. -
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. -
Flavor & Optional Texture
Stir in the vanilla extract. If using, fold in chopped nuts for texture. -
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. -
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. -
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.

❓ FAQ: Keto Chocolate Fudge with Keystone Pantry Allulose
Q: What makes this fudge keto-friendly?
A: Traditional fudge is loaded with sugar, but this recipe uses Keystone Pantry Allulose—a rare sugar that tastes like regular sugar, melts and caramelizes beautifully, yet has zero impact on blood glucose and net carbs. That’s why each piece has just 1g net carb.
Q: Does allulose taste different from sugar?
A: No—Keystone Pantry Allulose tastes almost identical to sugar. Unlike some sugar substitutes, it doesn’t have a cooling aftertaste, so your fudge tastes just like the classic version.
Q: Can I make this dairy-free?
A: Yes. Replace the heavy cream with full-fat coconut cream and use a plant-based butter alternative. The flavor will be slightly different but still rich and delicious.
Q: How long does this keto fudge last?
A: Stored in an airtight container in the fridge, it stays fresh for up to 2 weeks. For longer storage, freeze it for up to 3 months—just thaw in the fridge before serving.
Q: Can I add mix-ins?
A: Definitely! Chopped nuts, shredded coconut, or even sugar-free marshmallows can be folded in before chilling. For a gourmet touch, sprinkle flaky sea salt on top.
Q: Why is chilling time so important?
A: Fudge needs 2–3 hours in the fridge (or overnight) to fully set. Cutting it too early may result in soft, messy squares. Patience makes perfect fudge!
Q: Is this fudge safe for diabetics?
A: Keystone Pantry Allulose doesn’t raise blood sugar levels, making this fudge a great option for those managing carbs. However, as with any recipe, portion control and personal dietary needs should be considered.
Q: How many servings does this recipe make?
A: About 16 squares, but you can cut them smaller for bite-sized party treats or larger for indulgent servings.
