Add the Chocolate chips, butterscotch chips, and white chocolate chips to a large microwave safe bowl. Microwave in 30 second increments, stirring as much as you can after, until you can stir it totally smooth. 12 oz Chocolate Chips, 8 oz Butterscotch Chips, 4 oz White Chocolate Chips
Add the Peanut butter to the bowl and stir it in until its totally creamy and smooth. 10 oz Peanut Butter
Line a mini muffin pan, or two with paper liners. Pour the chocolate into the liners filling each about 3/4 of the way, you do not want to overfill them. You can use a pourable measuring cup, or transfer the chocolate into a clear squeeze bottle and use that to pour into the molds. (You can also pour the mixture into muffin liners, or mini muffin liners.) Tap the molds on the counter to flatten the chocolate.
Transfer the molds to the freezer for 10 minutes. Pop the chocolate out of the molds, and transfer them to a fridge safe container and store in the fridge for up to 2 weeks.
