Cookie Cake: Made Gluten-Free
Everyone loves a cookie cake. I mean truly, what is better than a giant chocolate chip cookie cake with frosting?
But it can be hard to find a store-bought gluten-free cookie cake, as I discovered years ago when my gluten-free 4-year-old asked for one for his birthday.
That is when I decided to use my Flourless Chocolate Chip Cookie recipe as inspiration to make a Gluten-Free Cookie Cake.
There are no fancy gluten-free flour blends or stabilizers needed in this recipe for a cookie cake. Instead, oats and peanut butter form the base of this giant chocolate chip cookie--meaning this is an affordable recipe to boot!
But more importantly, this recipe for a Gluten-Free Cookie Cake is just as delicious as the famous store-bought cookie cake! Perfect for any celebration!

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!
