After our trip, I kept thinking about that cookie, so I decided to try to make my own version.
It's not as pretty, but it was delicious!
My "lava" soaked into the cookie a bit, so it did not run out as well as the original. Still, it was super yummy!
How I did it:
(The brands I use are in parentheses; if you have a favorite brand it will likely work just as well.)
While still warm, fill the bottoms with Hershey syrup, cap with a cookie, and top with a scoop of non-dairy frozen dessert. (Almond Dream) Drizzle with Hershey syrup and dig in with a spoon.
Warning: this is a very rich dessert.
What to do with extra cookie dough: Make cookies, of course! I did them starting a little thicker, which is easier with the GF flour, and when they came out of the oven, I pressed a thumbprint into each one and filled the hollow with Hershey syrup.
