Ingredients

This fudge is remarkably simple, relying on a handful of pantry staples to achieve its incredible flavor and texture.

• 1 cup unsalted butter
• 8 ounces cream cheese, softened
• 1 cup creamy peanut butter (ensure it’s unsweetened and no added sugar for keto
• 1/4 cup unsweetened cocoa powder
• 1/2 cup granular sweetener (such as Splenda granular or your preferred keto-friendly sweetener)
• 1/2 teaspoon pure vanilla extract

Equipment Needed

You won’t need any fancy gadgets for this recipe. The essentials are:

• A microwave-safe mixing bowl
• A whisk
• A spatula
• An 8×8 inch baking pan
• Aluminum foil

Instructions

The beauty of this keto chocolate peanut butter fudge lies in its simplicity and speed. No ovens, no complicated techniques – just pure, delicious results.

1. Begin by lining an 8×8 inch baking pan with aluminum foil. Ensure the foil extends slightly up the sides of the pan to make lifting the fudge out easier later. Set this aside.
2. In a microwave-safe mixing bowl, combine the 1 cup of butter, 8 ounces of softened cream cheese, and 1 cup of creamy peanut butter.
3. Place the bowl in the microwave and heat on high power until the butter is completely melted. This typically takes about 2-3 minutes, but microwave times can vary, so keep an eye on it. You want a smooth, well-melted base.
4. Carefully remove the bowl from the microwave. Using your whisk, whisk together the melted butter, cream cheese, and peanut butter until the mixture is thoroughly combined and smooth. There should be no lumps of cream cheese remaining.
5. Now, it’s time to add the dry ingredients. Add the 1/4 cup of unsweetened cocoa powder, 1/2 cup of granular sweetener, and 1/2 teaspoon of vanilla extract to the bowl.
6. Whisk vigorously again until all the remaining ingredients are incorporated and the mixture is smooth and uniform in color. You’re looking for a rich, glossy chocolate batter.
7. Once the mixture is perfectly smooth, pour it into the prepared foil-lined 8×8 inch pan. Use a spatula to spread it evenly into the corners and ensure a flat surface.
8. Place the pan in the refrigerator and chill until set. This usually takes at least 2-3 hours, but overnight is even better for the firmest texture.
9. Once the fudge is firm and set, use the overhanging foil to lift the entire block of fudge out of the pan.
10. Place the fudge on a cutting board and cut it into 64 one-inch pieces. A sharp knife will make this process cleaner and easier.

Expert Tips & Tricks

As a chef, I’ve learned that even the simplest recipes can benefit from a few insider tips to elevate them from good to extraordinary.

• Cream Cheese Softness is Key: Ensure your cream cheese is truly softened. If it’s too cold, it won’t incorporate smoothly into the butter and peanut butter, leading to a lumpy fudge. You can speed this up by cutting it into small cubes and letting it sit at room temperature for about an hour, or briefly microwaving it on a very low power setting for 15-20 seconds.
• Peanut Butter Purity: For the purest keto flavor, opt for peanut butter that lists only peanuts and perhaps salt as ingredients. Many commercial brands contain added sugars and hydrogenated oils, which detract from the keto profile and can affect the texture. Natural peanut butter will also separate more, so give it a good stir before measuring.
• Sweetener Savvy: Different keto sweeteners have varying levels of sweetness and can sometimes have a cooling effect or aftertaste. Splenda granular is a reliable choice here, but feel free to experiment with erythritol, xylitol (if you don’t have pets, as it’s toxic to dogs), or a blend like Swerve. Adjust the amount slightly based on your preference.
• The Power of the Chill: Patience is a virtue when it comes to fudge! While the recipe states to refrigerate until set, allowing it to chill for a full 4-6 hours, or even overnight, will result in a much firmer, more sliceable fudge. This extra time allows the fats to solidify completely, giving you those perfect, clean cuts.
• Cutting for Cleanliness: For the cleanest cuts, consider chilling the fudge for an additional 15-30 minutes just before slicing. You can also run your knife under hot water and wipe it dry between cuts to prevent sticking and ensure sharp edges.

Serving & Storage Suggestions

This keto chocolate peanut butter fudge is a perfect standalone treat, but it also plays wonderfully with other desserts.

Serve chilled slices of this decadent fudge as an after-dinner indulgence, alongside a keto-friendly coffee or a glass of unsweetened almond milk. You can also arrange them on a small platter for a sophisticated dessert at gatherings.

To store, keep the fudge in an airtight container in the refrigerator. It will stay fresh and delicious for up to 2 weeks. Because of its high fat content, it can become quite soft at room temperature, so refrigeration is recommended for maintaining its fudgy texture. If you find it too firm after refrigeration, allow it to sit at room temperature for about 10-15 minutes before enjoying.

Variations & Substitutions

While this recipe is a classic for a reason, feel free to get creative with some delicious variations:

• Add a Crunch: For added texture, stir in 1/4 cup of chopped roasted peanuts or keto-friendly chocolate chips into the mixture just before pouring it into the pan.
• Swirl of Delight: Melt a small amount of sugar-free chocolate and drizzle it over the fudge before chilling. You can also swirl in a tablespoon of smooth almond butter or pecan butter for an extra layer of flavor.
• Peanut Butter Powder Power: If you’re looking to reduce fat slightly or intensify the peanut butter flavor, you can experiment with replacing some of the peanut butter with a good quality keto peanut butter powder. Start by replacing 1/4 cup of the liquid peanut butter with 1/4 cup of the powder, adding a touch more liquid sweetener if needed to achieve the right consistency.
