Best recipe I have found! So creamy and full of deliciousness!

I love this recipe! Delicious and easy! After following the directions, mine was the consistency of softset fudge, so I slowly added about 1/4c. more milk, and a dash of kosher salt.

Delicious, easy and very spreadable and yummy on this chocolate bunts cake

This was very tasty but a bit runny. When I make it again I will cut the milk amount in half, use 1 c. peanut butter, and more like 12 oz. of sugar.

I liked this recipe, but ended up not using all the sugar and adding more peanut butter and milk to it. It was to sweet and didn't have the peanutty taste to it before adjusting.

Super quick, easy and oh so yummy!!
