yield
12 rich and satisfying bars
Difficulty Level
Easy to Medium – perfect for home bakers eager to elevate their low-carb dessert game
Ingredients
- 1 cup unsweetened baking chocolate, finely chopped
- 3/4 cup unsalted butter
- 1 cup powdered erythritol (or your preferred low-carb sweetener)
- 1/2 cup heavy cream
- 1 tsp pure vanilla extract
- Pinch of sea salt
- 1/4 cup almond flour
- 1/4 cup chopped pecans or walnuts (optional)
Instructions
- Prepare your pan: Line an 8×8-inch square baking pan with parchment paper, ensuring some edges extend beyond the sides for easy removal.
- melt chocolate and butter: In a heatproof bowl over simmering water,gently melt the unsweetened baking chocolate and butter,stirring frequently until smooth and glossy.
- Add sweetener: Remove from heat and whisk in the powdered erythritol while the mixture is warm but not hot; this helps it dissolve fully for smooth sweetness.
- Incorporate cream and vanilla: Stir in the heavy cream, vanilla extract, and a pinch of sea salt, blending until silky and well combined.
- Fold in almond flour: Sift and gently fold in the almond flour to thicken the mixture-this adds structure without grit.
- Optional crunch: If using, fold in chopped nuts for texture contrast and nutty flavor.
- Pour and smooth: Transfer batter to the prepared pan, using a spatula to evenly spread and smooth the surface.
- Chill: Refrigerate for at least 2 hours until the fudge is set but still creamy. For firmer bars, chill overnight.
- Slice: Lift fudge from the pan using parchment edges and slice into 12 even bars with a sharp knife, wiping the blade between cuts for clean edges.
Tips for Success
- Ingredient temperature: use room-temperature butter and cream to avoid seizing the chocolate during melting.
- Sweetener choice: Powdered erythritol dissolves best to maintain smooth texture-avoid granulated forms which can create grit.
- Texture tweak: For creamier fudge,increase heavy cream by 1-2 tablespoons; for firmer bars,add an extra tablespoon of almond flour.
- Flavor boost: Boost depth by adding 1/2 teaspoon espresso powder or a splash of bourbon for adult flair without carbs.
- Make ahead: Fudge bars keep well refrigerated up to 1 week or freeze individually wrapped for up to 2 months.
Serving Suggestions

Pair with a dollop of unsweetened whipped cream or a few fresh raspberries to add a pop of color and brightness. For an elegant gathering, place each fudge bar next to a small shot of espresso or a cup of rich herbal tea.
