Clearly, I love pecans for this. In my opinion, pecans have the perfect, snackable size, and they have just the right amount of nooks and crannies to hold onto delicious coatings! However, you can use any nut you like for this. Walnut halves would be a close second for me. But almonds would also be good. A smaller nut like pistachios might take less baking time, so keep an eye on them. A mixed nut blend would be fun, too!
