Our peanut butter fudge might just be the perfect DIY candy for the peanut butter enthusiast in your life. This terrific sweet-and-salty treat is great just as it is, but you can dress it up in a number of ways. For even more peanut flavor, fold in 1/2 cup of chopped roasted and salted peanuts before transferring the fudge to the baking dish. Or try adding 1/2 cup of bittersweet, white or milk chocolate chips. For a PB&J-inspired treat, swirl in 1/3 cup of strawberry or grape jam.
