The word 'Haselnuss' (hazelnut) is made up of two parts: 'der Hasel' (the hazel, the bush on which the nuts grow) and 'die Nuss' (the nut). So it literally means 'nut from the hazel bush'.
Für den Kuchen brauchen wir gemahlene Haselnüsse.
For the cake, we need ground hazelnuts.
In everyday life, 'Haselnuss' (hazelnut) is often used with certain verbs. You can 'knacken' (crack open), 'sammeln' (collect), 'rösten' (roast), or 'mahlen' (grind) hazelnuts.

The hazelnut is a very popular ingredient in German cuisine, especially for sweets and baked goods. It is often found in chocolate, cakes, cookies, and spreads.
Mein Lieblingsbrotaufstrich ist eine Creme aus Schokolade und Haselnuss.

nut
'die Nuss' and 'die Haselnuss' both belong to the area of edible fruits with hard shells. 'Nuss' is the more general term: it can refer to many kinds, such as walnuts, almonds, or hazelnuts. 'Haselnuss' is more specific and only refers to the fruit of the hazel bush. The words can be confused because every hazelnut is a nut. But not every nut is a hazelnut. If the type matters, 'Haselnuss' fits better; if the type does not matter, 'Nuss' is enough.
