This recipe came from a 20 year old magazine, it's a wonderful cake, moist, easy to make and freezes well. The name of this cake is derived from the buttery brown sugar topping that sinks into the cake as it bakes and forms a crusty layer reminiscent of a lunar landscape!

This was a fantastic moist and delicious cake! It had the texture and flavor of a coffee cake, which I loved. I made it exactly as directed and it did really take on that 'lunar' look. I think it would be great with any fruit - apples, blueberries, peaches....!

My mother had this same recipe Magazine and used to make this cake when I was younger. It is my alltime favorite cake as I'm not a huge fan of overly sweet cakes. The topping is just sweet enough to mellow out the tartness of the rhubarb, while the rhubarb tones down the sweetness. I've been looking to find the recipe for this cake for years and was absolutely thrilled to find it here!!
