We’ve all been lamenting the summer’s end. And though we’re looking forward to the fall, and all that the autumnal harvest has to offer (have we mentioned that it’s apple season??), we’re still grasping onto the last of the summer fruit, which will be gone all too soon - within the next few weeks. We thought that plum season was already over, but Mr. Wickham told us we’ll have one more week to enjoy his farm’s excellent red plums, and we couldn’t be happier to hold on to summer just a little bit longer!Once you taste this cake, you will understand why the recipe has been so popular over the years. It is extremely simple to make, and it contains – besides the plums – a handful of very common pantry staples: flour, butter, sugar, baking powder, salt, cinnamon, lemon juice, and eggs. But don’t let the simplicity of the ingredients fool you. Once you add the plums to the top of the batter and the cake bakes up around them, the plums soften and their juices seep into the surrounding cake. It’s a delicious cake, made even more delicious as the cake sits overnight and the plum juices further penetrate it.Note: I didn’t have my springform pan on hand when I made this, but I wish I did. If you don’t have one, the cake will still bake up beautifully, but you may need to sacrifice the first slice in order to get the remaining slices out of the pan in one piece. Enjoy!
