📝 Ingredients

For the Fudge

8 oz (225 g) cream cheese, softened
¼ cup unsalted butter, softened
½ cup powdered keto sweetener (erythritol or monk fruit)
¼ cup unsweetened cocoa powder
½ cup chocolate protein powder (optional for extra protein)
1 teaspoon vanilla extract
¼ teaspoon sea salt
½ cup sugar-free dark chocolate chips, melted
2 tablespoons heavy whipping cream

Optional Toppings

Sugar-free chocolate drizzle
Chopped pecans or walnuts
Flaky sea salt

Directions

Line an 8×4-inch loaf pan with parchment paper.
In a large mixing bowl, beat the softened cream cheese and butter on medium speed for 2–3 minutes until smooth and fluffy.
Add powdered keto sweetener, cocoa powder, protein powder (if using), vanilla, and sea salt. Mix on low speed until fully combined.
Melt the sugar-free chocolate chips with the heavy cream over low heat or in the microwave in 20-second intervals, stirring until smooth.
Pour the melted chocolate into the cream cheese mixture and beat until silky and completely incorporated.
Spread the mixture evenly into the prepared loaf pan using a spatula.
Smooth the surface and add optional chocolate drizzle or chopped nuts.
Refrigerate for at least 3 hours, or overnight, until fully firm.
Lift the fudge from the pan using the parchment paper and cut into 16 squares with a warm knife.

High-protein tip: For the highest protein content, use a keto-friendly chocolate whey isolate or collagen peptides in place of part of the cocoa powder.
