My husband and I, while we were still dating, used to meet at our local Red Robin after work for our midweek dates. His favorite drink during the sumemr was the Peanutty Freeze. It's basically just a chocolate and peanut butter milkshake. My husband was really disappointed when Red Robin changed their menu many years ago, eliminating the Peanutty Freeze altogether. My husband has missed this milkshake ever since. So I went on a search for the recipe so he would be able to have his favorite milkshake now and then at home. After much begging, I eventually came upon this recipe for the Red Robin Peanutty Freeze (chocolate peanut butter milkshake).
