Combine ingredients in slow cooker and stir. Cook on high for 30 minutes. Stir and turn to warm setting. Use banana, apple, or marshmellow to dip in fondue.
If you are a peanut butter and chocolate fan you will love this fondue. It was so easy and so delicious. We served ours with chunks of angel food cake, strawberries, and bananas. The bananas were the best! It would also be an awesome ice cream topper. 4 stars.
