What You’ll Need
Main Ingredients:
- Peanut butter – 1 cup (creamy works best, but crunchy adds texture)
- Butter – 1/2 cup (4 tablespoons)
- Vanilla extract – 1 teaspoon
- Powdered sugar – 3 1/2 cups (sifted for smoothness)
- Salt – 1/4 teaspoon (optional but enhances flavor)
For the Pan:
- Cooking spray or butter for greasing
- Parchment paper (makes removal easier)
Substitution Notes:
- Natural peanut butter → Regular peanut butter (natural can be too oily)
- Butter → Coconut oil for dairy-free option
- Powdered sugar → Blend granulated sugar in a blender until powdery
- Vanilla → Almond extract for a different flavor profile
Step-by-Step Directions
Step 1: Prepare Your Pan
Line an 8×8 inch baking pan with parchment paper, leaving some overhang for easy removal. Lightly grease the parchment with cooking spray or butter. This prevents sticking and makes cutting clean squares a breeze.
Step 2: Mix the Base
In a large microwave-safe bowl, combine peanut butter and butter. Make sure your bowl is large enough—the mixture will bubble up during cooking, and you don’t want overflow in your microwave.
Pro Tip: Use room temperature ingredients for smoother mixing. Cold butter takes longer to melt evenly.
Step 3: Microwave Magic
Microwave on high for 2 minutes. Remove and stir well with a wooden spoon or whisk. The mixture should be smooth and completely melted. If there are still butter chunks, microwave for an additional 30 seconds.
Step 4: Add Flavor
Stir in vanilla extract and salt until well combined. The vanilla adds depth, while the salt enhances the peanut butter flavor and balances the sweetness.
Step 5: Incorporate Sugar
Gradually add powdered sugar, mixing continuously. Start with about 1 cup at a time to prevent lumps. The mixture will be thick—this is exactly what you want! Keep stirring until completely smooth.
Important: Don’t add all the sugar at once. This creates lumps that are hard to work out.
Step 6: Final Mix
Give everything one last good stir. The fudge should be thick, creamy, and hold together when stirred. If it seems too soft, add a bit more powdered sugar, 1/4 cup at a time.
Step 7: Set the Fudge
Pour the mixture into your prepared pan. Use a spatula to spread evenly and smooth the top. Refrigerate for at least 1 hour until firm enough to cut.
Step 8: Cut and Serve
Lift the fudge out using parchment paper and place on a cutting board. Cut into 16 squares using a sharp knife. For clean cuts, wipe the knife between each slice.

Expert Tips for Success
Storage Secrets:
Room temperature: Store in an airtight container for up to 1 week. Layer between parchment paper to prevent sticking.
Refrigerator: Keeps for up to 3 weeks when properly wrapped. Bring to room temperature for best texture before serving.
Freezer: Wrap individual pieces and freeze for up to 3 months. Thaw at room temperature for 15 minutes.
Texture Tweaks:
- For firmer fudge: Add an extra 1/4 cup powdered sugar
- For softer fudge: Reduce powdered sugar by 1/4 cup
- For extra richness: Use natural peanut butter with oil on top
Flavor Variations:
- Chocolate Swirl: Drizzle 1/4 cup melted chocolate and swirl with a knife
- Crunchy Delight: Add 1/2 cup chopped peanuts or pretzels
- Cookie Crunch: Fold in 1/2 cup crushed graham crackers

Master Chef Secret: Let the fudge come to room temperature before cutting. Cold fudge can crack, while room temperature fudge cuts clean.
Common Questions
Can I use natural peanut butter?
Natural peanut butter works, but drain off excess oil first. The oil can make your fudge too soft and greasy. Stir well before measuring to ensure even consistency.
Why is my fudge too soft?
This usually means too much liquid or not enough powdered sugar. Add more powdered sugar 1/4 cup at a time until you reach the right consistency. Also, make sure you’re measuring ingredients accurately.
Can I double the recipe?
Absolutely! Use a larger microwave-safe bowl and increase cooking time to 3-4 minutes. You may need to stop and stir halfway through to ensure even melting.
What if I don’t have powdered sugar?
Make your own by blending granulated sugar in a high-speed blender or food processor until it becomes powder. You’ll need about 2 3/4 cups granulated sugar to make 3 1/2 cups powdered.
How do I prevent the fudge from sticking?
Always line your pan with parchment paper and lightly grease it. This combination makes removal effortless and gives you clean edges for cutting.
