This bouncy, tender spiced cake celebrates winter persimmons in all their glory. Baking wedged Fuyu persimmons — the squat, tomatolike ones — until their flavor concentrates and their moisture dissipates leaves you with syrupy fruit that doesn’t sog up the cake later. A little coconut extract, a whisper of the tropical, props up the gentle sweet aroma of the orange fruit, with cardamom playing a major role in bringing out its floral, pumpkiny qualities. Whipped cream folded into the batter at the end, a trick from the baker Heather Dekker-Hurlbert, results in a light, even crumb. Thanks to a sprinkling of cardamon sugar on top before baking, the cake gains a glorious caramelized crust with cinnamon toast vibes (but cardamom).
