(WFLA) — A new study by HelloFresh found that the cost of baking a batch of cookies for Christmas is joining the list of holiday traditions hurt by rising inflation.

They’re calling it the Christmas Cookie Price Index.

The study examined the cost of key ingredients for cookies, like butter, milk, eggs, flour, sugar and baking soda across 60 cities in the United States and 30 countries around the world. For the sake of the study, the methodology says a batch consists of 100 cookies made from a “classic butter cookie recipe.” More specifically, the study used this cookie recipe from John Kanell at Preppy Kitchen.

Of the 60 cities surveyed, the most expensive was San Diego where a single batch of cookies is expected to cost bakers $12.40.

Here are the top 10 most expensive U.S. cities to bake Christmas cookies in 2021, according to the study.

City, StatePrice (USD)
1. San Diego, California$12.40
2. Burlington, Vermont$12.08
3. Los Angeles California$11.41
