Yes! If you want these to look more like Reese Peanut Butter cups, you can make them in a muffin cup. Line 12 muffin cups with paper liners. Pour your peanut butter & graham cracker mixture evenly into the 12 muffin cups. Pour your melted chocolate and peanut butter into the 12 muffin cups; chill your entire muffin tray for 2 hours. Enjoy!
