This supremely moist, single-layer chocolate cake gets its tender crumb and rich flavor from full-fat Greek yogurt and vegetable oil. It requires no frosting—just a dusting of powdered sugar—and delivers a deeply chocolatey, not-too-sweet experience perfect with coffee or as an elegant, simple dessert.
Storage: Cool completely, then wrap tightly in plastic wrap or store in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days. Let come to room temperature before serving for best texture. Freezing: Wrap the whole cooled cake or individual slices tightly in plastic wrap, then in aluminum foil or a freezer bag. Freeze for up to 3 months. Thaw overnight in the refrigerator or at room temperature for several hours. Reheating: For a warm cake, place a slice on a microwave-safe plate and microwave in 10-second bursts until just warmed through, being careful not to overheat and dry it out. Alternatively, warm in a 300°F (149°C) oven for 5-8 minutes.
