Thanks for sharing such a great recipe. Do you still use the Kerrygold butter in this and do you use bleached or unbleached flour when you bake this? Thanks!!
Hi Marcy,
Yes, we used Kerrygold butter and King Arthur All-Purpose flour (which is unbleached). Happy baking!
I made this for my son’s 10th birthday party tonight. My husband and I think it’s the best cookie cake we’ve ever had! I made it in a 13×9 glass dish and it came out beautifully. Also, I used salted butter because I had it and forgot to adjust the salt it called for and it was fine. We will be making this for every birthday going forward!
