Everyone loves a cookie cake!
But while this cookie cake is just as delicious as the famous store-bought cookie cake, it also happens to be gluten-free.
Why did I make this Cookie Cake gluten-free?
Well, years ago, my son and I were both gluten-free. And we went to many parties over that time that there were no dessert options for us. Not very fun for a 4-year-old boy or his mom’s sweet tooth!!
So ever since that time, I always want to have gluten-free options for friends or company if needed–without having to buy special flours or mixes.
Wouldn’t it be nice if you could always have an easy, tasty go-to gluten-free recipe for yourself or your gluten-free friends?
That is EXACTLY why I made this cookie cake gluten-free.

I have a quick question! The intitial instructions say blend the oats, then measure out 2 cups. The ingredient list seems to indicate the same as it says “2 cups blended oats (about 3 cups oats)” but then there is a special note At the bottom that says: “The oats are to be measured BEFORE blending in this recipe for Chocolate Chip Peanut Butter Cookie Cake.” Which one should I follow? Thanks for your help, this looks too yummy and I don’t want to mess it up!
Oh goodness, I need to change that asap it should say “measured AFTER blending” Fixing now. I hope you enjoy.
Thank you so much for your quick response! Just came out of the oven…looks and smells delicious! Cant wait to taste it.
I hope you enjoy Sarah!
