My husband and I used to meet occasionally at our local Red Robin Restaurant after work for midweek dates. His favorite drink during the summertime was the Peanutty Freeze. He was really disappointed when Red Robin changed their menu many years ago, eliminating the Peanutty Freeze altogether. It didn't seem all that complicated--ice cream, chocolate, and peanuts all whipped together. So I tried to recreate it at home, and I came up with this recipe. So he can still have his favorite milkshake at home now.
