I am all but a beginner with baking, and this was an easy recipe. This was a pretty good cake. I liked the tang of the orange. I used plain nonfat yogurt because that's what I had. Because I didn't have blueberries, I substituted 1 1/2 c. frozen whole cherries for the blueberries. This worked pretty well, and the cake baked up nicely.
This was highly enjoyable. I didn't have any plain yoghurt on hand so used low-fat yoghurt with honey. Seemed to work OK. Made a nice big cake, so in theory it SHOULD last a couple of days, probably not though, it is too good to last too long.
