Decadent Peanut Butter Chocolate Swirl Fudge made easily in the microwave. Great for holidays, gift giving or anytime you need a rich peanut butter treat.

Peanut butter lovers rejoice! This fudge only has a few basic ingredients you probably have in your pantry and it microwaves in just 4 minutes.... and then you have to wait FOREVER for it to set.
Okay, maybe it only seems like forever.
With all of the butter in this recipe, it was so rich that I am glad I added the dark chocolate swirl to balance it out a bit. I had dark chocolate melting wafers on hand, but you could easily use chocolate chips or baking chocolate with a little butter or coconut oil to help it mix smoothly.
Since the mixtures are rather thick and the pieces would eventually be cut rather small, I didn't really swirl the chocolate and peanut butter like I would for a marble cake. Instead I left the peanut butter layers a bit uneven and then added the chocolate to even it out.
