If you love sweet treats but still want to stay on track with your keto diet, this Keto Peanut Butter Fudge with Cream Cheese is going to become your new favorite dessert. It has the perfect texture—smooth, thick, creamy, and melt-in-your-mouth – just like classic traditional fudge, but without sugar and without the heavy carbs.

This recipe is made with simple pantry ingredients like unsweetened peanut butter, cream cheese, and butter, then sweetened with a keto powdered sweetener. The result is a rich and satisfying low carb peanut butter fudge that tastes like a real cheat dessert, but it’s actually sugar-free, gluten-free, and keto-friendly.

What makes this fudge extra special is the cream cheese. It gives the fudge a softer, creamier texture and helps it set beautifully in the fridge. Many keto fudge recipes can become too oily or too stiff, but cream cheese balances everything and gives that perfect “bite”. This is also why this recipe is often considered one of the best keto fat bomb dessert recipes for people who want a sweet snack without kicking out of ketosis.

Ingredients overview (what each ingredient does)

This recipe uses only a handful of ingredients, but each one plays an important role in making the fudge taste and set like real fudge.

Cream Cheese

Cream cheese gives this keto fudge its thick, smooth texture. It also adds a light tang that balances sweetness and makes the flavor more “rich” instead of overly sweet.

If you don’t have cream cheese, you can use similar soft cheese options like Neufchatel (same style but lighter), or even ricotta (texture will change slightly).

Butter

Butter adds richness and helps create that classic fudge texture. It also helps the mixture firm up once chilled.

Tip: If your peanut butter is salty, unsalted butter works best. But if you only have salted butter, the recipe still works fine.

Unsweetened Peanut Butter

Peanut butter is the star here. For the best keto result, use:

• Natural creamy peanut butter
• No added sugar
• No hydrogenated oils (if possible)

Homemade peanut butter also works very well.

Vanilla Extract

Vanilla improves flavor and makes the fudge taste more like a bakery-style dessert. It also hides any aftertaste from sweeteners.

Sugar-Free Powdered Sweetener

Powdered sweetener helps the fudge stay smooth (granulated sweetener can feel grainy). A confectioners-style keto sweetener like Swerve Confectioners works great.

Unflavored Whey Protein

This ingredient helps the fudge set without adding more powdered sweetener. It improves firmness and gives the fudge that perfect sliceable texture.

If you don’t want whey, you can replace it with:

• collagen powder (keto-friendly)
• peanut flour (for extra peanut flavor)

Stevia Concentrated Powder

Stevia boosts sweetness without adding carbs. It also reduces the need for extra powdered sweetener.

How to make keto peanut butter fudge (easy method)

Making this recipe is simple. You don’t need candy thermometers, complicated steps, or baking.

1. First, melt the butter and cream cheese gently.
2. Add peanut butter and mix until smooth.
3. Remove heat and stir in sweeteners and powders.
4. Blend until the mixture becomes creamy and thick.
5. Pour into pan, chill, and slice.

Extra Notes

Notes for best results

• Chill longer for cleaner slices (overnight is best)
• Use powdered sweetener to avoid grainy texture
• Mix well to prevent oil separation
• If mixture looks oily: let it cool slightly, then use a hand mixer

Storage

Because it contains cream cheese, keep it chilled:

• Fridge: 2–3 weeks in an airtight container
• Freezer: up to 3 months
  Tip: freeze in layers with parchment so pieces don’t stick.

Optional Add-Ins

• keto chocolate chips (mix in or sprinkle)
• swirl melted sugar-free chocolate on top
• add pinch of sea salt for better flavor
