Natural peanut butter (no sugar added)

Vanilla for warm bakery-style flavor

It chills quickly, slices beautifully, and stores for several days—perfect for holiday prep.

⭐ Keto Peanut Butter Fudge Recipe

Prep Time: 10 minutes

Chill Time: 60 minutes

Makes: 16 small squares

Ingredients

1 cup natural peanut butter, creamy and unsweetened

4 oz cream cheese, softened (or coconut cream for dairy-free)

4 tbsp butter or coconut oil

½ cup Truvia, powdered (or powdered erythritol)

1 tsp vanilla extract

Pinch of salt

Optional: ¼ cup chopped pecans or walnuts

Instructions

Soften the Base

In a saucepan over low heat, melt the butter and cream cheese until smooth. Stir continuously to prevent sticking.

Add the Peanut Butter

Stir in the peanut butter and continue mixing until it becomes silky and fully combined.

Sweeten It

Add in the powdered Truvia and whisk until smooth. Mix slowly so the sweetener dissolves evenly.

Finish With Flavor

Turn off heat and stir in the vanilla extract and pinch of salt.

Pour & Chill

Pour the mixture into an 8×8 lined baking dish. Smooth the top with a spatula.

Optional: Sprinkle chopped nuts on top for crunch.

Chill Until Firm

Refrigerate for at least 1 hour or until completely set.

Slice & Serve

Cut into small squares. Store in the refrigerator and serve chilled.

Tips for Perfect Keto Peanut Butter Fudge

✓ Use powdered sweetener. Granular sweeteners will make the fudge gritty.

✓ Use runny natural peanut butter. Thick or dry peanut butter affects texture.

✓ Don’t skip the chill time. The fudge firms up as it cools.

✓ Warm the knife before slicing. Clean edges every time.

✓ Keep refrigerated. Keto fudge softens at room temperature.
