These Hazelnut Snowball Cookies are delicate, melt-in-your-mouth treats that combine buttery richness with the warm, nutty flavor of finely chopped hazelnuts. Lightly crisp on the outside and tender inside, each cookie is rolled in powdered sugar twice, giving it a snowy, festive appearance and a sweet, meltaway finish. Perfect for holiday gatherings or as a cozy indulgence with tea or coffee.
