Preheat the oven to 350°F. In the bowl of a stand mixer fitted with the paddle attachment, beat the cold butter for 1 minute.
Add the sugar and mix for 2 minutes, scraping down the sides and bottom of the bowl as needed.
Mix in the almond extract. Gradually add the flour and blend just until the dough comes together. (It will seem very crumbly, just be patient and keep mixing.)
Scoop the dough into 1-tablespoon portions and roll each portion into a ball. Arrange the dough balls on the baking sheets, spacing them 2 inches apart.
Press a wide, shallow indentation into the center of each one using the bottom of a wooden spoon or a spatula handle. Fill each indentation with a heaping ¼teaspoon of raspberry jam.
Transfer cookie sheets to the fridge to allow cookies to chill for 20 minutes.
Bake for only 11 to 12 minutes. They will not seem done but they are! The cookies should remain soft and will firm up as they cool—avoid over-baking or they’ll turn crunchy.
Allow cookies to cool for 5 minutes on the baking sheet then transfer to a cooling rack and allow them to cool completely.
