Grandma's assistant baker

Not only was Bubby's visit to Grandma's the first time he rode on a plane without Mom or Dad and the first time he slept in the big boy guest room all by himself, it was his very first time to bake cookies -- chocolate-chip cookies! -- with Grandma.

 

Mmmm, mmmm, mmmm! Finger-lickin' good!

Today's question:

Chocolate-chip cookies are my signature baked good. What is yours? (If anyone wants the recipe from another commenter, say so in the comments and I'll conduct a recipe swap through e-mail. OR ... you're welcome to include your recipe with your comment to begin with!)
