These Jingle Bell Bites are miniature shortbread Christmas cookies with green and red nonpareils speckled throughout for fun holiday cheer!
Preheat the oven to 325 degrees F. Butter the bottom and sides of an 8x8-inch pan, then line with parchment paper, pressing the sides and corners to stick.
In a large mixing bowl, beat the butter, sugar and extract at medium speed until creamy, about 1-2 minutes. Add the flour and salt. Mix on low speed until a dough forms. It will be crumbly for a while, but keep beating. Stir in the nonpareils until evenly distributed.
