Step-by-Step Guide to This Sourdough Crumbl Cookie-Inspired Treat

These cookies have all the texture and size of your favorite bakery-style treat. Here’s how to make them step by step:

1. Melt the butter and let it cool slightly. In a large bowl, whisk together the butter, brown sugar, and granulated sugar until well combined.
