Before making the cookies, remove the butter from the refrigerator, cut into cubes and leave it at room temperature until soft. Soak the raisins in warm water for about 30 minutes, changing the water a few times

Preheat oven to 350 degrees F

In a large bowl combine all ingredients except raisins using a hand mixer. Beat for a few minutes at medium speed until the butter is creamy and all ingredients are incorporated

Incorporate the soaked and drained raisins into the dough using a spatula

To make the cookies, spoon the dough and use your hands to form equal-sized balls. If the dough is too sticky, wet your hands lightly with cold water. Place the dough balls on a parchment paper-lined cookie sheet and then press them down gently with your hands (I used a little heart-shaped cookie press) to give the cookies a flatter shape

Bake the cookies in the preheated oven for about 30 minutes
