Oh man!  Doesn’t it look amazing!

Hands down this was the best coffee cake I’ve ever had.  Yes.  I just said that.  Best. Coffee. Cake. EVER!

It was so good that I’m making it again this weekend to take to a morning meeting at work on Monday.  They are going to love me.

When I first saw this recipe I knew it had to be a good one.  Just look at the streusel topping!

The thought did cross my mind, though, about the thickness of the topping.  Was it going to be too sweet?  Would it be too much and overpower the cinnamon cake?  Ummm, I’m here to tell you, that answer is a big, fat NO.  It was perfect.
