This would be the perfect dessert to serve on the first cool night of fall. Generally, coffee is the only deep flavor balancing tiramisu, but here, molasses does double-duty: adding both complex sweetness and a spicy depth. To make the tiramisu, you beat the molasses with mascarpone and heavy cream and layer it with coffee-soaked ladyfingers. For an even coating of cocoa powder on top, use a fine-mesh strainer. It’ll help you sift evenly and avoid clumps. Enjoy with coffee alongside—but keep it decaf if you’re serving after dinner.
