I'm happy to be sharing a recipe over on Erin's blog, The Spiffy Cookie. She provided me with a drool-worthy guest post, so I was happy to return the favor. I had a jar of Cookie Butter in my pantry that was just begging to be used. After several spoonfuls I decided to bake it up in a cookie sandwich. Thanks Erin for letting me share my recipe on your blog. And like promised, let me know if you need me to ship you some jars of Cookie Butter!
