These are not your ordinary peanut butter cups. The filling is creamy, smooth and oh so good. I was looking for a recipe close to what I could get at Rocky Mountain Chocolate before they changed the recipe and ruined them. While making buckeyes I got the inspiration to try. I find buckeyes too sweet and they don't have as big a peanut butter flavor as I was craving. This is what I came up with. Close in my opinion but then again it's been nearly 7 years since I had one from Rocky Mountain Chocolate. But these sure do fill the void. These are meant to be rich and decadent. The use of silicon cups makes it much easier to coat with chocolate than paper would be. When you peel back the silicon, you're left with a perfect beautiful rippled cup. It leaves you thinking "did I really make these". I experimented with the chocolate. I preferred milk chocolate to semi sweet chocolate chips. I used Belgian fondue chocolate (comes in wafers), it melted easier and smoother than chocolate chips. The chips melted in your hands fast and was a little more messy to eat. I also preferred regular peanut butter to light. It gave me the consistency I desired. But use what you like. Makes 12 but you might want to share one with a friend, or maybe not!
