Do I have to chill the cookie dough before baking?

If at all possible, I really recommend it. Chilling the dough helps ensure the cookies will be nice and tall after baking & minimizes spread during the baking process.

Where else can I use cookie butter?

Cookie butter is so versatile! We like to use it on fruit, graham crackers, or ginger snaps. It's also a great sweet substitute in recipes that call for creamy peanut butter.

Can I make this cookie without a mixer?

You can absolutely make this without a stand mixer or hand mixer - just get ready to use those arm muscles. :) The cookie dough is really thick, so it can be difficult to blend well without a mixer. Make sure all ingredients are stirred thoroughly!
