Chocolate-Coconut Cake

Four layers of tender buttermilk-chocolate cake, pockets of shredded coconut baked right into the crumb, a bittersweet walnut-chocolate filling, and clouds of unsweetened whipped cream between the tiers. This is a proper layer cake, the kind you bring out for birthdays and anniversaries and anyone whose chocolate allegiance runs deep.

The cake itself relies on a one-bowl method: melt the unsweetened chocolate, dump the dry ingredients and buttermilk straight in, and beat until smooth. The buttermilk plus baking soda combo is what gives the crumb its tender, faintly tangy lift, while the flaked coconut stirred in at the end turns every slice into a chewy-tender surprise. Dusting the greased pans with cocoa (not flour) keeps the outside of the cake purely chocolate, no floury white edges to distract.

Chef Tips

• Cool the melted chocolate slightly before adding to the batter or you risk scrambling the eggs.
• Split the layers with a long serrated knife using a sawing motion; a turntable helps keep cuts even.
• The walnut filling is a cooked custard. Stir constantly over medium-low heat until thick so the yolks do not curdle.
• Assemble on a chilled plate and chill the finished cake 30 minutes before slicing for clean layers.

Variations

• Swap walnuts in the filling for toasted pecans for a sweeter, milder nut flavor.
• Add half a teaspoon of almond extract to the batter for a subtle complexity alongside the coconut.
• Finish with a dusting of toasted coconut flakes on top for a German chocolate style presentation.
