Black beans in a chocolate cake recipe? Don’t be so quick to sneer. The flavor of the beans is undetectable; they mainly contribute to the fudgy consistency of this flourless dessert, an adaptation of a brownie recipe from 101 Cookbooks.
Instead of making a jellyroll pan full of brownies, like the original
recipe calls for, I made two 9" layers and filled the center with a
thin layer of raspberry preserves. You can easily make your own
filling by pureeing and straining fresh or frozen raspberries or just
buy an all-fruit variety of preserves.
