Ingredients You’ll Need
· 1 cup (2 sticks) unsalted butter, softened
· 1 cup creamy peanut butter (not natural; use a stabilized brand like Jif or Skippy for best results)
· 3 to 3 1/2 cups powdered sugar (confectioners’ sugar), sifted
· 1 teaspoon pure vanilla extract
Optional: 1/4 teaspoon salt (if using unsalted peanut butter), 1/2 cup chopped peanuts for crunch, flaky sea salt for topping
Step-by-Step Instructions
- Prepare the Pan: Line an 8×8 inch square baking dish with parchment paper or aluminum foil, leaving some overhang for easy removal. Lightly grease if using foil.
- Melt Butter and Peanut Butter: In a large microwave-safe bowl, combine the softened butter and creamy peanut butter. Microwave in 30-second intervals, stirring between each, until fully melted and smooth (about 1 to 1 1/2 minutes total).
- Add Vanilla: Stir in the vanilla extract until well combined. If adding salt, stir it in now.
- Add Powdered Sugar: Gradually add the sifted powdered sugar, one cup at a time, stirring vigorously with a wooden spoon or spatula after each addition. The mixture will become thick and slightly stiff. You may need to use your hands to knead in the last bit of sugar.
- Press into Pan: Transfer the fudge mixture to the prepared baking dish. Press it evenly into the corners and smooth the top with a spatula or your hands. If using chopped peanuts, sprinkle them on top and gently press them in.
- Chill: Refrigerate for at least 2 hours, or until the fudge is firm and set. For faster setting, place in the freezer for 30-45 minutes.
- Slice and Serve: Use the parchment overhang to lift the fudge out of the pan. Cut into small squares—this fudge is rich! Serve chilled or at room temperature.
Tips for the Creamiest Fudge
· Use Stabilized Peanut Butter: Natural peanut butter separates and can make the fudge oily or grainy. Stick with creamy, no-stir brands like Jif, Skippy, or store-brand equivalents.
· Sift the Powdered Sugar: This prevents lumps and ensures a silky smooth texture.
· Don’t Overheat: Melt the butter and peanut butter just until smooth. Overheating can cause the fats to separate.
· Knead for Smoothness: If the mixture seems too stiff or grainy, knead it with your hands for a minute—the warmth helps everything come together.
· Cut Small Pieces: This fudge is very rich. Small squares are perfect.
· Room Temperature Serving: For the creamiest texture, let the fudge sit at room temperature for 10-15 minutes before serving.
Variations & Substitutions
· Chocolate Peanut Butter Fudge: Add 1/2 cup cocoa powder along with the powdered sugar, or swirl in 1/4 cup melted chocolate.
· Crunchy Peanut Butter Fudge: Use crunchy peanut butter or add 1/2 cup chopped roasted peanuts.
· Honey Peanut Butter Fudge: Replace 1/4 cup powdered sugar with 2 tablespoons honey for a honey-roasted flavor.
· Vegan Version: Use vegan butter, a creamy no-stir plant-based peanut butter, and ensure powdered sugar is vegan-friendly.
· Sea Salt Topping: Sprinkle flaky sea salt over the top before chilling for a sweet-salty contrast.
Frequently Asked Questions
Can I use natural peanut butter?
It’s not recommended. Natural peanut butter has separated oils that can make the fudge greasy or prevent it from setting properly. If you must use it, stir very well and expect a softer texture.
How do I store peanut butter fudge?
Store in an airtight container in the refrigerator for up to 2 weeks. For best texture, let it come to room temperature before serving. You can also freeze for up to 3 months.
Why is my fudge too soft?
This usually means there’s too much moisture or not enough powdered sugar. Make sure you used a stabilized peanut butter and measured the powdered sugar correctly. If soft, refrigerate longer or add a bit more powdered sugar and re-chill.
Why is my fudge grainy?
Graininess can happen if the powdered sugar wasn’t fully dissolved or if the mixture wasn’t stirred enough. Sifting the sugar helps, and kneading the mixture with your hands can smooth it out.
Can I make this in the microwave only?
Yes! This entire recipe can be made in the microwave. Just melt the butter and peanut butter, then stir in remaining ingredients. No stovetop needed.
Can I use crunchy peanut butter?
Absolutely. Crunchy peanut butter adds wonderful texture. You can also add chopped peanuts to creamy peanut butter for the same effect.
