These were delicious! If you love chocolate with a delightful crunch of toasted nuts these cookies will make you very happy. They were very moist, so the slivered almonds that I used were a perfect complement. I’m sort of meh about hazelnuts, so I decided to substitute Trader Joe’s Cocoa Almond spread instead. I’ve never tried it before, and I noticed that it doesn’t have a strong nut flavor (while Nutella is very hazelnutty). If you want a cookie that is more chocolate the TJ’s spread makes a good alternative.
