1/2 cup milk
1 cup peanut butter
1 teaspoon vanilla extract

How to Make Peanut Butter Fudge
Step 1: Boil the Sugar and Milk
In a saucepan, combine the sugar and milk. Place over medium-high heat and bring the mixture to a rapid boil, stirring occasionally. Once boiling, continue to boil for exactly 2½ minutes.
Step 2: Add Peanut Butter and Vanilla
Remove the saucepan from heat. Immediately add the peanut butter and vanilla extract. Stir continuously until the peanut butter is completely melted and the mixture is smooth and creamy.
Step 3: Pour and Set
Pour the hot fudge mixture into a greased 8×8-inch pan for a single batch, or an 11×13-inch pan if doubling the recipe. Spread evenly with a spatula.
Step 4: Cool and Slice
Allow the fudge to cool at room temperature until fully set. Once firm, cut into squares and serve.
Texture and Flavor
This fudge is soft, creamy, and rich without being grainy or overly sweet. The peanut butter flavor is bold and comforting, making it a favorite for both kids and adults. It melts slightly in your mouth while still holding its shape perfectly.
Tips for Perfect Fudge Every Time
Measure the boiling time carefully—overboiling can cause the fudge to become dry. Stir quickly once the peanut butter is added to keep the mixture smooth. Use regular creamy peanut butter for best results, not natural peanut butter with separated oils.
Storage and Gifting Tips
Store the fudge in an airtight container at room temperature for up to 5 days, or refrigerate for longer storage. It also freezes well. This fudge makes an excellent homemade gift for holidays, cookie trays, and special occasions.
