How to Make No-Bake Peanut Butter Fudge
- Line a pan: Grease and line an 8×8-inch baking pan with parchment paper, leaving a 2-inch overhang on both sides to lift the fudge out easily once it’s chilled and set.
- Melt the butter: In a medium microwave-safe bowl, heat softened butter on medium power for 30-second intervals, stirring between each until smooth and completely melted (about 1 minute total).
- Stir in peanut butter: Add creamy peanut butter to the melted butter and stir vigorously until you see a glossy, uniform mixture with no streaks of butter or nuts (about 2 minutes).
- Mix in sugar and vanilla: Gradually blend powdered sugar and vanilla extract into the peanut butter mixture until creamy, thick, and slightly stiff, ensuring there are no lumps or dry pockets remaining (about 1 minute).
For the Topping: - Add mix-ins and press: Fold in chopped peanuts or mini chocolate chips, then transfer the fudge mixture to the prepared pan, pressing firmly into an even layer so the top is smooth and level.
- Chill until firm: Cover the pan loosely with plastic wrap and refrigerate for at least 2 hours, or until the fudge feels firm to the touch and slices cleanly without sticking.
Optional: Sprinkle a pinch of flaky sea salt over the top before chilling.

No-Bake Peanut Butter Fudge Recipe FAQs
How do I know if my peanut butter is the right type for this fudge?
Creamy peanut butter is your best bet for smooth, melt-in-your-mouth No-Bake Peanut Butter Fudge. Avoid chunky varieties, as they can disrupt the creamy texture, though a small amount of nuts can be folded in later for crunch.
What’s the best way to store leftover fudge to keep it fresh?
Absolutely keep it in an airtight container! At room temperature, your fudge will happily last about a week if kept away from heat or sunlight. For a longer shelf life, refrigeration is perfect—up to 2 weeks—and just pull it out a little before serving to soften.
Can I freeze No-Bake Peanut Butter Fudge, and how do I thaw it?
Yes, freezing is a fantastic option! Wrap your fudge tightly in plastic wrap to keep out freezer odors, then place it in a freezer-safe bag. It can stay frozen for up to 2 months. When you’re ready to enjoy, thaw it overnight in the fridge, then bring it to room temperature before serving for that perfect creamy texture.
What if my fudge turns out grainy or hard instead of creamy?
Don’t worry, this is pretty common! Make sure your butter is softened, not melted when mixing; melting can cause separation. Also, sift your powdered sugar to avoid lumps, and stir thoroughly but gently—not too vigorously to keep that velvety smoothness. If the fudge is too stiff, adding a tiny bit more melted butter or peanut butter before setting can help.
Is this fudge safe for pets or people with nut allergies?
Please avoid sharing this fudge with pets or those allergic to peanuts, as peanut butter can be harmful or trigger allergic reactions. For nut-free alternatives, consider recipes using sunflower seed butter or cookie butter instead—but keep in mind, those will change the flavor and texture profile quite a bit!
