Here’s the recipe to make the original Girl Scout Cookie from 1917

There’s a big birthday worth celebrating this year. Girl Scout cookies have been around for a whole century now, and 2017 is their hundredth birthday. Sounds like a pretty good reason to buy all the Girl Scout cookies, right? Hey, you’re an adult. Go for it.

We’ve learned a few things about the history of Girl Scout cookies since their birthday was announced. For example, the Girl Scouts shared the very first Girl Scout cookie recipe ever published in the The American Girl. You’ll be shocked at how simple the recipe is, and you might be inspired to do some baking on your own. Here’s how you make the original Girl Scout Cookies, courtesy of the Girl Scouts of the USA.

Ingredients
1 cup of butter, or substitute
1 cup of sugar
2 tablespoons of milk
2 eggs
1 teaspoon of vanilla
2 cups of flour
2 teaspoons of baking powder

Method

Cream butter and sugar; add well-beaten eggs, then milk, flavoring, flour, and baking powder. Roll thin and bake in quick oven. (Sprinkle sugar on top.)

This recipe is meant to make six or seven dozen cookies, and the Girl Scouts were originally meant to sell them for 24 to 35 cents a dozen. Oh, how simple life used to be.

We also learned that, although Girl Scouts started fundraising in 1917, they weren’t commercially produced and sold en masse until the 1930s. That’s why this recipe was so useful. Individual scouting troops used to bake dozens of cookies on their own and go around selling the batches on their own. We won’t lie. We’re curious. If you need us, we’ll be in the kitchen baking all day.
