I found it to be excellent. Not dense for me at all! I give samples to people who stop at my Farmers Market, and they usually place an order for it!
This is indeed a dense cake. I used nowhere near 6-8 plums. Maybe our greek plums are much, much smaller but I used 22 for this cake. Good thing I had that many! Otherwise, delicious.
A fairly dense cake with a muffin-like texture. The crumb topping completely covers the plums so there's no need to arrange them artfully. The second time I made this cake I simply cut my plums in half and overlapped them closely on the batter. The cake tends to be a bit dry so the more plums, the more moist the cake. I easily used 30 plums. The baking time was right on.
