Ingredients & Kitchen Tools
Ingredients:
– 1 cup creamy peanut butter – Adds rich, nutty flavor. Use natural peanut butter for fewer additives, but note it may require extra powdered sugar for consistency.
– ½ cup unsalted butter – Provides smoothness and helps set the fudge. Salted butter can be used if you reduce added salt.
– 1 teaspoon vanilla extract – Enhances sweetness and depth. Pure vanilla is best; imitation works but use slightly less.
– 2 cups powdered sugar – Sweetens and thickens the mixture. Sift before using to avoid lumps.
– Optional: ¼ teaspoon salt – Balances sweetness. Omit if using salted butter or peanut butter with salt.
Kitchen Tools:
– 8×8-inch baking pan – For setting the fudge. Line with parchment paper for easy removal.
– Microwave-safe bowl – Large enough to hold all ingredients without overflowing.
– Spatula or wooden spoon – For stirring. Silicone is non-stick.
– Measuring cups and spoons – Ensure accurate proportions.
– Knife – For cutting fudge into squares.
Prep Time & Cooking Schedule

– Prep time: 10 minutes – measure and soften ingredients.
– Cook time: 5 minutes – melt peanut butter and butter in the microwave.
– Resting time: 2 hours – chilling in the refrigerator until firm.
– Total time: Approximately 2 hours 15 minutes.
Plan ahead: Make this fudge the day before if serving at a party. The active effort is only 15 minutes, making it perfect for last-minute dessert needs. The resting time is hands-off, so you can prepare it while your oven is free.
Step-by-Step Instructions
1. Prepare the pan: Line an 8×8-inch pan with parchment paper, leaving overhangs on two sides for easy lifting. Set aside.
2. Melt the base: In a large microwave-safe bowl, combine 1 cup creamy peanut butter and ½ cup unsalted butter. Microwave in 30-second intervals on high, stirring after each, until fully melted and smooth (about 1.5–2 minutes total). Tip: Overheating can cause separation; stop as soon as it’s liquid.
3. Add flavor: Stir in 1 teaspoon vanilla extract and optional ¼ teaspoon salt. Mix until incorporated.
4. Incorporate sugar: Gradually sift 2 cups powdered sugar into the warm mixture, stirring continuously. Start with 1 cup, then slowly add the rest. The mixture will thicken into a stiff dough-like consistency. Textural cue: It should pull away from the bowl edges but still be glossy.
5. Press into pan: Transfer the fudge into the prepared pan. Use a spatula or your hands (lightly oiled) to press it evenly into the corners. For smooth top, cover with parchment and press with a flat object.
6. Chill: Refrigerate for at least 2 hours until firm. Note the time as you prepare this Peanut Butter Fudge; this step ensures clean cuts. This technique is common in many Fudge Recipes.
7. Cut and serve: Lift the fudge from the pan using parchment. Cut into 1-inch squares using a sharp knife. Wipe the blade between cuts for neat edges.
Nutritional Benefits & Advantages
This fudge offers more than sweetness. Peanut butter is a rich source of plant-based protein (about 8 grams per 2-tablespoon serving) and healthy monounsaturated fats, which support heart health. It also provides vitamin E, magnesium, and potassium. When made at home, you can reduce sugar by using alternatives like monk fruit sweetener (though texture may change). The no-bake method preserves these nutrients better than high-heat baking. For those mindful of calories, this fudge is satisfying in small portions—a single square (about 1.5 tablespoons) contains roughly 120–150 calories, depending on ingredients.
Tips Variations & Cooking Advice
Flavor Variations:
– Chocolate swirl: Melt ½ cup semi-sweet chocolate chips and swirl into the fudge before chilling.
– Crunchy texture: Use crunchy peanut butter or mix in ¼ cup chopped roasted peanuts.
– Savory-sweet: Add a pinch of sea salt flakes on top after pressing.
Dietary Adaptations:
– Vegan: Substitute butter with coconut oil or vegan butter; ensure powdered sugar is vegan (some brands use bone char).
– Gluten-free: This recipe is naturally gluten-free as long as your vanilla extract and powdered sugar are certified.
– Low-carb: Use powdered erythritol or monk fruit-based sugar replacement. Note the fudge may be slightly softer.
Cooking Methods:
– Stovetop: Melt peanut butter and butter in a saucepan over low heat, stirring constantly.
– Double batch: Double all ingredients for a 9×13-inch pan; increase chilling time to 3 hours.
Common Mistakes to Avoid
– Overheating the base: High heat or over-microwaving can cause the peanut butter and butter to separate. Solution: Use short bursts and stir often. If separation occurs, whisk in a tablespoon of hot water.
– Too much or too little powdered sugar: Adding too little makes fudge runny; too much makes it crumbly. Solution: Sift sugar and add gradually. The mixture should hold shape when pressed.
– Pressing too hard: Over-compressing creates dense, rock-hard fudge. Solution: Press gently and evenly; a light touch ensures a tender bite.
– Not allowing enough chilling time: Removing fudge after only an hour results in sticky, messy cuts. Solution: Wait at least 2 hours; for best results, chill overnight.
Storage & Meal Prep Tips
– Refrigeration: Store fudge in an airtight container in the fridge for up to 2 weeks. Separate layers with parchment paper to prevent sticking.
– Freezing: Wrap fudge squares individually in plastic wrap, then place in a freezer-safe bag. Freeze for up to 3 months. Thaw in the refrigerator overnight before serving.
– Reheating: If fudge becomes too hard from cold storage, let it sit at room temperature for 10–15 minutes. Avoid microwaving, as this can melt the texture.
– Meal prep: Make a batch on Sunday for weekday treats. Cut and portion into small containers for grab-and-go snacks.

FAQs
1. Can I use natural peanut butter instead of creamy processed peanut butter?
Yes, but natural peanut butter is often oilier and less sweet. You may need to add up to ¼ cup more powdered sugar to achieve the right texture. Ensure it’s well-stirred before measuring.
2. How do I make this fudge vegan?
Replace butter with vegan butter or refined coconut oil. Use vegan-certified powdered sugar and vanilla extract. The fudge will be slightly softer but equally delicious.
3. Why is my fudge too soft and not setting?
This typically happens due to insufficient chilling time or too little powdered sugar. Ensure you refrigerate for at least 2 hours. If still soft after chilling, add 1–2 tablespoons more powdered sugar and re-press.
4. Can I add nuts or chocolate chips to the mixture?
Absolutely! Fold in ½ cup chopped peanuts, walnuts, or chocolate chips after mixing the sugar. For chocolate chips, let the mixture cool slightly first to prevent melting.
5. How long does this fudge stay fresh at room temperature?
It’s best refrigerated. At room temperature (below 75°F), it can sit out for up to 3–4 hours in a cool, dry place. Beyond that, it may become sticky or soften.
