Marble Cake Recipe with Meyer Lemon and Chocolate

This marble cake recipe combines Meyer lemons (a beautifully fragrant cross between regular lemons and oranges) with chocolate. If you can’t find Meyer lemons (when in season, usually available in upscale grocery stores like Whole Foods) feel free to substitute regular lemons or oranges in its place. Adding the cocoa to the boiling water in the recipe “blooms” the chocolate flavor and makes it more pronounced than just adding the cocoa straight into the batter. The touch of instant coffee also helps boosts the chocolate but if you don’t have any on hand and don’t feel like running to the store for it, just leave it out.
