Hallongrotta is the name for Swedish cookies which have been prepared and consumed at least since the 1800s, at Swedish coffee parties called kafferep. The cookies are typically made with butter, flour, baking powder, sugar, vanilla, and raspberry jam, which goes in the indentation (usually made with one's thumb) in the middle of each cookie.

The name hallongrotta means raspberry cave, and in the United States, these tiny treats are better known as thumbprint cookies. It is recommended to serve them with tea, coffee, or milk on the side.
