Ingredients
- 1 cup creamy peanut butter (240 g)
- 1 cup unsalted butter (2 sticks or 226 g)
- 1 teaspoon vanilla extract
- 4 cups powdered sugar (480 g)
How to Make Easy Peanut Butter Fudge Squares
STEP 1: In a large microwave-safe bowl, combine peanut butter and butter. Microwave on high for 2 minutes, stir well, then microwave for another 1–2 minutes until completely melted and smooth.
STEP 2: Stir in the vanilla extract until fully blended.
STEP 3: Gradually add the powdered sugar, stirring after each addition. The mixture will become thick and slightly stiff — that’s exactly what you want. Keep mixing until it’s smooth and well combined.
STEP 4: Press the fudge mixture evenly into an 8×8-inch dish lined with parchment paper or lightly greased. Smooth the top with a spatula.
STEP 5: Refrigerate for at least 2 hours, or until the fudge is firm and set.
STEP 6: Lift the fudge out using the parchment paper and slice into squares. Store in an airtight container in the refrigerator for up to one week.
Tips for Perfect Fudge
- For a saltier twist, use salted butter or sprinkle a pinch of flaky sea salt on top before chilling.
- Want a little crunch? Fold in ½ cup of crushed peanuts before spreading into the pan.
- Need it dairy-free? Substitute vegan butter or coconut oil for an easy, no-dairy version.
Smooth, sweet, and perfectly peanutty — this Easy Peanut Butter Fudge is a simple pleasure that never disappoints.
