Cake Crumb Cookies

Preheat the oven to 350 degrees.

In the bowl of a food processor, pulse the cubed cake a few times until finely crumbled. Reserve 1 ½ cups and reserve the rest for later use.

Combine the butter, sugars, egg, extract, and salt until well combined. In another bowl, combine the baking soda, flour, and cake crumbs. Combine and chill the dough, then scoop out onto a silicone or parchment-lined baking sheet. Bake in  for 10-12 minutes or until golden brown.
