Used Gluten Free oreo, which tastes the best. Also spouse purchases a gluten free. Chocolate cookie K-Toos. Those weren't tasty. I didn't add correctly, so only had one package of gf oreos. I had to use the K-Toos for the chocolate layer. Next time. I'll make sure to buy enough gf oreos. Not too sweet, which is how I like my desserts. It's also no bake, which is a win in my book.
