The Wirral-born 27-year-old smashed home the 20th-minute penalty which gave the Potters back-to-back home league wins over the Reds for the first time since 1968.
Having missed from the spot at Norwich late last month, the Republic of Ireland international took no chances, and said: "I said to myself if I win another one I'll get up and take it and there was no putting it in the corner, it was blast it straight down the middle."
Inflicting Liverpool's first defeat of the campaign was particularly sweet for a player from an Evertonian family.
"It's a Blue family so they are all happy," added Walters, who was born in Moreton.
"The majority of my family are Evertonians, although my wife's father is a Red. I'm a bit happier because I'm a Blue.
"A goal's a goal but it is always sweet to score against Liverpool really.
"My brother was here - he's a Blue and he was made up."
