Lovely. Made as per recipe but didn't make the icing for the top as I put half the streusel in the cake and the other half on top before baking. Best coffee cake recipe I've made so far and very easy.
Absolutely delicious! Incredibly moist and flavorful. I usually use Greek yogurt because that is what I have on-hand. The streusel makes a lot. I would actually cut it in half. Next time I make this I will also sprinkle the streusel on the bottom of the pan.
