Dressing is perfect!
Not a big fan of mayo, loved the Greek yogurt swap. Reduced garlic a bit. Dressing was delish!
Best coffee cake- ever!!
This recipe was not the easiest to follow due to how it was written. It requires a lot of back and forth from instructions to the lists of ingredients but oh, hey, the end result is totally worth the effort! Mouthwatering and delicious plus it’s a pretty presentation.
