This chocolate dessert features a smooth, dense texture topped with flaky sea salt to create a balanced flavor profile. The fudge is prepared by combining sugar-free dark chocolate with butter and heavy cream, resulting in a glossy mixture that sets in the refrigerator. It is portioned into small squares and offers a rich cocoa taste without the use of traditional sugars.

About This Recipe

The preparation begins by melting sugar-free dark chocolate chips and unsalted butter together in a heatproof bowl. Once the mixture is smooth, heavy cream, powdered sweetener, and vanilla extract are whisked into the liquid until the batter becomes uniform and glossy. This mixture is poured into a small dish lined with parchment paper and smoothed with a spatula to ensure an even surface. The tray is tapped lightly against the counter to remove trapped air before the final garnish is added.

The ingredients include high-quality sugar-free chocolate and butter, which provide the primary fat content and structural base for the fudge. Heavy cream is stirred in to influence the final softness of the squares, while powdered erythritol or allulose provides the sweetness. Flaky sea salt is applied to the surface before the chilling process to contrast with the dark chocolate. The dish is placed in the refrigerator for at least one to two hours to allow the components to firm into a sliceable consistency.

The recipe is modified by adding crushed pecans or almonds for a different texture or by stirring in a swirl of natural peanut butter before the cooling stage. For a seasonal variation, peppermint extract can be used in place of vanilla. The finished fudge is lifted from the pan using the parchment paper and sliced into 16 individual squares. The portions are stored in an airtight container in the refrigerator or freezer and are served chilled to maintain their firm shape.
