I was really excited to try this and even ran out to buy a bundt pan specifically for this. I was really disappointed in the result. While it baked beautifully and the cake texture was moist and soft, it was bland. The coffee streusel was really bitter. I used a name brand espresso powder and followed the measurements exactly. I prefer really good quality coffee, and this cake tasted like cheapo gas station coffee. My husband and his co-worker tried it and were also unimpressed. I won't make this again. I love the idea of it, though, and would like to find a coffee flavored recipe that does not rely on harsh espresso powder for the bulk of its flavor.
Pros: moist cake, baked perfectly, lovely presentation
Cons: bitter coffee taste, bland cake
