This Old-Fashioned No-Bake Peanut Butter fudge is nostalgic, nutty, and perfectly sweet. Plus, it only requires ten minutes of active cooking time and 5 ingredients!
Add butter to a large pot over medium heat, stirring occasionally until it's completely melted.
½ cup unsalted butter
Add milk and brown sugar to the melted butter and whisk until smooth. Then, set your whisk down and watch as your mixture comes to a boil.
1 cup milk, 2 cups light or dark brown sugar
Once it's reached a rolling boil, set your timer for two minutes. After two minutes of boiling, remove the pot from the heat and whisk in peanut butter.
1 cup creamy peanut butter
To a large mixing bowl, add the powdered sugar and the peanut butter fudge mixture. Use a hand mixer on high to mix until smooth.
2 ¼ cup powdered sugar
Transfer peanut butter fudge mixture to an 8x8-inch baking pan. Use a spatula to smooth out the mixture so that it's spread evenly in the pan. *
Place the pan in the refrigerator to cool for at least an hour.
Remove the fudge from the pan and use a sharp knife to slice into 16 roughly even squares. Option to add sea salt. Store in the fridge and enjoy within 10 days.
¼ teaspoon sea salt
Notes
*You have the option to line the baking pan with parchment paper for easier removal, but the fudge has enough butter in it to make it naturally nonstick, so it's up to you!
This fudge is best when stored in the refrigerator. It can also be frozen for up to 6 months.
