A few years ago, I became e-talented a recipe for an easy fruit-topped cake referred to as Cup o’ Cup o’ Cup o’. The electronic mail ended with “I wager my mom made one thousand of those whilst we have been children.” The instantly-up recipe begins with melting a stick of butter in 
the oven within the cake pan (less complicated to oil the pan), then pouring the liquid butter right into a bowl with a cup of flour, a cup of milk and a cup of sugar, plus a very good amount of baking powder. Once those elements are stirred together and scraped into the pan, a rebellion of summer fruit is dumped on top and the cake bakes into both a puddinglike form, warm and gooey or a more impregnable cake with properly-browned edges, completely depending on the quantity of time it spends inside the oven.
I made the cake some times and favored it nicely sufficient. It becomes near, but not the deal with I idea it is able to be. I was less keen on the pudding shape and greater entranced with the one’s crispy edges. I started working and made this cake my personal, one meant for the potluck table. In the past month, I doled out this cake to buddies, family contributors, workmen, and shortly-to-be-friends, making a dozen versions until it reached, in my thoughts, its complete capacity.
From the outset, I knew I desired this to be a buttermilk cake. Buttermilk from my local dairy is thick and creamy and glugs out of the bottle. For this cake, the buttermilk from the grocery store works as nicely, but the thicker model makes a cake with a barely more wet and soft crumb.
Changing from entire milk to buttermilk within the authentic cake supposed adjusting the leavening from baking powder to baking soda (unlike milk, buttermilk does no longer want cream of tartar, an acidic element in baking powder, to set off the leavening), and I fiddled with the quantity of, properly, the whole thing else. I delivered eggs. I upped the flour. I modified the ratio of fruit to the batter. And I modified the pan size. The end result is a cake that is extremely muffin-like, a little like an espresso cake, and reminiscent of pound cake.
I used whatever fruit became accessible to top the cake. I combined berries. I used white and yellow peaches. I stirred together candy and bitter cherries. Any fruit fits the invoice and smells the cake whilst it bakes.
This is a cake that any baker will want to make their own. I understand because I gave the recipe to two pals and that they each changed it up. I use vanilla to further heady scent the cake, but my buddy Gail used almond extract. When I brought cinnamon, I idea it crushed the taste of the fruit and the tang of the buttermilk, but Abbie introduced nutmeg and turned into satisfied. I assume cardamom might be delicious, too.
Here is your new pass-to summer cake. Make it once, and I suspect you’ll make it over and over, as I actually have. Slice the cake into massive rectangular slabs; no one will complain if their piece has a scoop of ice cream snuggling up subsequent to it. Around right here, we’ve been calling it breakfast cake with surely no guilt. And if there is buttermilk left over, it makes delicious biscuits, is a splendid brine for the bird, and is a superb sipping drink on a warm day, or so said, my grandfather.
