Which nut type is used in the Five Nut Brownie?

The Five Nut Brownie is designed to include a diverse array of flavors and textures, which is achieved by incorporating five different types of nuts. This variety not only enhances the taste profile of the brownie but also adds a delightful crunch and richness to the dessert. The inclusion of multiple nuts allows for a complex combination of nuttiness that appeals to different palates, making it a unique treat compared to brownies made with a single type of nut or none at all. The other options do not capture the essence of the recipe, which emphasizes the use of a mix of nuts to create a signature flavor.
