Yeast cookies are a delicious preparation with roots in the baking traditions of various Latin American regions. Originally, these cookies emerged as a way to utilize natural yeast to achieve a soft texture and a slightly fermented flavor, very distinct from conventional cookies. In different Latin American countries, this sweet treat may have various names; for example, in Mexico they are usually called "yeast cookies," while in some regions of Central America they are known as "fermented little cakes" or simply "fermented dough cookies." Their history is linked to the European influence on American cuisine, where fermentation was a common method to improve the fluffiness and preservation of baked goods.
This type of cookie is especially appreciated for breakfasts and snacks, as their softness and unique flavor pair perfectly with jams, butter, or simply accompanied by coffee or tea. Over time, this recipe has been adapted and passed down from generation to generation, keeping alive the tradition of preparing homemade cookies that stand out for their light texture and crispy edge, thanks to the use of yeast along with other leavening agents.
