Tips for making your peanut butter cookies

Peanut butter properties

Did you know that peanuts are actually legumes? Although known as a dry fruit, the peanut is the edible seed of the leguminous plant Arachis hypogaea , belonging to the Fabaceae family.

We advise you to buy a natural peanut butter without additives or added sugar  like this one . We also recommend the one that they sell in Mercadona from their Hacendado brand, which has very good quality and is 100% natural.

Regarding the question of whether peanuts are fattening , the answer is that if they are consumed in moderation they do not have to be. Of course, it is necessary to moderate its consumption because peanut butter, although it is suitable for ketogenic diets , contains the not insignificant figure of 618 kcal per 100 g . Doing a quick calculation, each peanut butter cookie would provide us with about 94 kcal , something that is not a problem if we take some every day, since they are also quite satiating.

According to the Spanish Nutrition Foundation , it is a legume source of protein (albumin) and fat , almost as much as meat. Almost 50% of its fat is monounsaturated, and 29% polyunsaturated omega-6. It contains 27% protein, and fiber in considerable quantities. They are also a source of phosphorus, potassium, magnesium and zinc (an average serving of peanuts is equivalent to 15 and 12%, respectively, of the recommended daily intakes of phosphorus and magnesium).

As for vitamins , niacin stands out , followed by vitamin E. For example, 25 g of shelled peanuts provide 35% of the recommended intake of niacin for women.

If you see cracks appearing in the cookies, do not worry because it is absolutely normal, in fact it is part of its charm. You will see that when you remove them they are still soft and in fact you must be careful and remove them with a kitchen trowel so that they do not break. Once they cool completely they will be crispy and delicious, perfect to drink with a good glass of milk.
