Ingredients You’ll Need
Here’s everything required to make this delicious fudge:
- 1 cup natural peanut butter (no sugar added)
Go for a smooth, creamy peanut butter for the best texture. Make sure it’s unsweetened to keep it keto-friendly. - ½ cup unsalted butter
This adds richness and helps create that silky fudge consistency. - ¾ cup powdered erythritol or monk fruit sweetener
These are great low-carb sugar alternatives. Powdered form works best to avoid a grainy texture. - 1 teaspoon vanilla extract
Adds a subtle sweetness and enhances the overall flavor.
That’s it—just four main ingredients, and you’re set.
Step-by-Step Instructions
1. Prepare Your Pan
Start by lining an 8×8 baking dish with parchment paper. This makes it super easy to lift the fudge out later and keeps cleanup simple.
2. Melt the Base
In a saucepan over low heat, combine the butter and peanut butter. Stir continuously until everything melts together into a smooth, creamy mixture. Keep the heat low to avoid burning or separating the oils.
3. Mix in Sweetness
Once melted, remove the pan from heat. Add the powdered sweetener and vanilla extract. Whisk everything together until the mixture is fully combined and silky smooth. Make sure there are no lumps.
4. Pour and Spread
Pour the mixture into your prepared baking dish. Use a spatula to spread it evenly, smoothing out the top for a clean finish.
5. Chill Until Firm
Place the dish in the refrigerator and let it chill for about 1 to 2 hours. The fudge will firm up as it cools.
6. Slice and Enjoy
Once set, lift the fudge out using the parchment paper. Cut it into small squares and enjoy!
Texture & Flavor
This fudge is all about balance. It’s rich but not overpowering, sweet but not too sweet, and incredibly smooth. The peanut butter flavor shines through, while the butter adds a luxurious, melt-in-your-mouth feel.
Because it’s made with low-carb sweeteners, it won’t have that heavy sugar aftertaste. Instead, it’s clean, satisfying, and perfect for anyone watching their sugar intake.
Tips for the Best Results
- Use powdered sweetener
Granulated versions can make the fudge grainy. If needed, blend your sweetener into a powder before using. - Don’t overheat the mixture
Keep the heat low when melting to maintain a smooth consistency. - Taste before setting
Want it sweeter? Adjust the sweetener before pouring it into the dish. - Let it fully chill
Don’t rush the process—proper chilling gives you that perfect fudge texture.
Storage Tips
- Refrigerator: Store in an airtight container for up to 1 week
- Freezer: Can be frozen for up to 2 months
- Serving tip: Let it sit at room temperature for a few minutes before eating for the best texture
Variations You Can Try

- Chocolate Swirl: Add melted sugar-free chocolate on top and swirl it in
