Shape dough into 1 ¼ inch balls. Roll chopped peanuts.
Set dough balls on baking sheet. Do not flatten.
After you put the cookies in the oven, unwrap the peanut butter cups.
Bake at 350 degrees for 8 to 10 minutes. DO NOT OVERBAKE. Cookies will be soft. When you remove them from the oven, immediately press a frozen, unwrapped peanut butter cup into the center.
Let cool on pan for 1 minute, and then move to cooling rack.
When cookies are cooled, it is time to drizzle the peanut butter chips over them. Melt the peanut butter chips at 50% in the microwave for about 1 minute. Stir until smooth. Add the melted chips to a plastic sandwich bag and cut off a small corner. Squeeze the peanut butter in a zigzag patter over each cookie.
Let the peanut butter set before stacking or putting cookies away.
