Well, these aren’t ordinary chocolate cookies, these cookies are baking and “decorated” using the glass bottom method.

It’s a way of producing a moist centered cookie, with a sugar crunch on top. You can use an antique glass with a design in the bottom or you can use the bottom of a metal measuring cup to apply the sugar to baked cookies.

In order to get the sugar to stick to the bottom of my measuring cup (or glass) use a little dab of butter so it will stick.

When the cookies come out of the oven, gently press the sugar into them. The edges of the cookies may “crack” a bit, that’s ok, don’t squish them too much. Just gently press.

These cookies are irresistible! These are the kind of cookies you like to have sitting in the cookie jar on the counter. I love seeing a full cookie jar.

Now you can add on frosting onto the cookies…. oh these are so fun, the frosting will firm up enough if you want to stack them in a cookie jar, or wrap them up and put them in lunch boxes, bring them to a friends house and sit and chat…these are that kinds of cookies, the kind of cookies that are perfect anytime!
