Description

This Sugar-Free Peanut Butter Fudge is rich, creamy, and packed with classic peanut butter flavor without traditional added sugar. Each bite has a soft, melt-in-your-mouth texture that makes it perfect when you’re craving something sweet but want to keep carbohydrates more moderate.

Made with natural peanut butter, cream cheese, and a low-carb sweetener, this recipe is simple enough for beginners and convenient enough for meal prep. It can also fit nicely into a low-carb and high-protein lifestyle when portioned appropriately.

Diabetic-friendly note: This recipe uses sugar-free ingredients and is designed to be lower in carbohydrates than traditional fudge. However, it still contains carbohydrates and calories, so portion size and individual dietary needs matter.

Can This Sugar-Free Peanut Butter Fudge Support Weight Loss Goals?

It can fit into a weight-conscious eating plan when enjoyed in a controlled portion. Peanut butter and cream cheese provide fat and some protein, which can make a small serving satisfying and help it feel more substantial than a traditional sugary candy.

Because fudge is calorie-dense, portion control is especially important. Pairing a small square with a protein-rich meal or snack can help create a more balanced eating pattern.

Does Sugar-Free Peanut Butter Fudge Fit a High-Protein Lifestyle?

This fudge can fit a high-protein lifestyle, although it is better described as a protein-supportive dessert rather than a high-protein food on its own.
Peanut butter and cream cheese provide some protein, while the sugar-free sweetener keeps added sugar low.
Depending on the ingredients used, each piece can contain approximately 3–4 g protein and around 2–3 g net carbs.
For more protein, use powdered peanut butter or add a small amount of vanilla protein powder to the mixture.

Common Mistakes to Avoid

  1. Using overly runny peanut butter — Excess oil can prevent the fudge from setting firmly.
  2. Adding too much liquid — Too much milk or cream can make the fudge soft and difficult to slice.
  3. Not softening the cream cheese — Cold cream cheese can leave lumps in the finished mixture.
  4. Cutting it before it is fully chilled — Give the fudge enough time to firm up for clean squares.

Required Equipment

  • Small saucepan — Gently melts and combines the ingredients without scorching.
  • Rubber spatula — Scrapes the pan clean and creates a smooth mixture.
  • Mixing bowl — Provides room for combining the creamy ingredients.
  • 8-inch square pan — Creates evenly sized fudge pieces.
  • Parchment paper — Makes removing the chilled fudge much easier.
  • Sharp knife — Produces neat, clean squares after chilling.

Storage Instructions

Refrigerator: Place the cut fudge squares in an airtight container, separating layers with parchment paper. Refrigerate for up to 7 days.

Freezer: Wrap individual pieces in parchment or plastic wrap and place them in a freezer-safe airtight container or freezer bag. Freeze for up to 2 months.

Thawing: Transfer frozen pieces to the refrigerator and allow them to thaw for several hours before serving.

For convenient portion control, freeze the fudge as individual squares rather than storing the entire batch together.

📝 Ingredients

  • 1 cup (250 g) creamy natural peanut butter, unsweetened
  • 4 oz (113 g) full-fat or reduced-fat cream cheese, softened
  • ¼ cup (60 ml) unsweetened almond milk
  • ⅓ cup powdered monk-fruit/erythritol sweetener, or to taste
  • 2 tablespoons unsalted butter
  • 1 teaspoon vanilla extract
  • ¼ teaspoon salt
  • 2 tablespoons powdered peanut butter, optional for extra peanut flavor and protein

Ingredient note: Use peanut butter without added sugar when possible. Different sugar-free sweeteners have different levels of sweetness, so adjust according to taste.

Directions

1. Prepare the pan

Line an 8-inch square pan with parchment paper, leaving some paper hanging over the sides.

This creates handles that make the chilled fudge easy to lift out.

2. Warm the peanut butter mixture

Place peanut butter and butter in a small saucepan over low heat.

Warm for approximately 2–3 minutes, stirring continuously until smooth and glossy.

Do not use high heat, because peanut butter can scorch and become oily.

3. Add the cream cheese

Add softened cream cheese and continue stirring over low heat for 1–2 minutes.

The mixture should become smooth and creamy with no visible cream-cheese lumps.

4. Add sweetener and flavor

Remove the saucepan from the heat.

Stir in powdered sweetener, vanilla extract, salt, and optional powdered peanut butter or protein powder.

Mix for 30–60 seconds until evenly incorporated.

High-protein tip: If adding protein powder, mix it in gradually to prevent dry pockets and add 1–2 teaspoons of almond milk if the mixture becomes too thick.

5. Transfer to the pan

Pour the warm mixture into the parchment-lined pan.

Use a spatula to spread it into an even layer approximately ½–¾ inch thick.

The surface should appear smooth and glossy.

6. Chill

Place the pan in the refrigerator for at least 2 hours.

For the firmest texture, chill for 3–4 hours or overnight.

7. Slice

Lift the chilled fudge from the pan using the parchment handles.

Cut into 24 small squares with a sharp knife.

For cleaner cuts, wipe the knife between slices.

8. Serve

Allow one piece to sit at room temperature for approximately 3–5 minutes before serving.

This gives the fudge a softer, creamier bite.
