Grandma's Peanut Butter Fudge

Begin by sifting granulated sugar through a fine-mesh sieve into a spacious container, resulting in an even distribution of the sweetener.

This is followed by heating a mixture of butter and peanut butter in a saucepan over medium heat. Utilizing a whisk, combine the ingredients thoroughly and cook until tiny bubbles form on the edges of the pan, taking approximately 3 to 5 minutes. Introduce salt and vanilla extract into the mixture, stirring until fully incorporated.

Then, pour the warm butter-peanut butter mixture over a generous amount of powdered sugar in the bowl. Utilize a spatula to blend the ingredients together until they achieve a smooth consistency.

Next, transfer the mixture into an 8x8-inch baking pan that has been lined with plastic wrap. Ensure the entire surface is covered and refrigerate until the fudge reaches a suitable consistency for cutting, typically between 1 to 3 hours.

Finally, remove the fudge from the refrigerator and carefully unwrap it. Cut into small cubes and allow them to warm up on a countertop surface before serving, if necessary.
