How to Make Peanut Butter Fudge

7. Fast 4-Ingredient Peanut Butter Fudge

This 10-minute method of making peanut butter fudge is almost completely fail-safe. The peanut butter fudge can be cooked in an oven or microwave. Combine 1.25 cups of peanut butter and 1.25 cups of butter in a saucepan. Bring the mixture to a boil. Remove the saucepan from heat immediately after reaching the boiling point. Stir in 1.5 tsp of vanilla extract, 4.5 cups of confectioner's sugar, and a pinch of salt. Pour the mixture into a greased 8 inch baking dish. Smooth the surface and cover with plastic wrap directly on the fudge. Chill in the refrigerator for at least one hour so the fudge sets. For the microwave method, put the peanut butter and butter in a large microwavable bowl covered with a paper towel. Microwave for two minutes and finish the rest of the normal recipe.
