Martha Stewart's one-bowl chocolate cake (made eggless) yields an incredibly moist yet sturdy cake that can stand up to layering and is easy to throw together. Tangy yogurt frosting is the perfect accompaniment to this decadent single slice of chocolate layer cake.

Ingredients
For the cake
1/2cupall-purpose flour
1/2cupsugar
1/4cupunsweetened cocoa powder
1/2teaspoonbaking soda
1/4teaspoonsbaking powder
1/4cupwarm water
1/4teaspoonkosher salt
2tablespoonsmilk
2tablespoonsplain Greek or regular yogurt
2tablespoonsvegetable oil
1/4teaspoonpure vanilla extract
For the frosting
1/2cupplain Greek or regular yogurt
2-3tablespoonsgranulated sugar or other sweetener
2tablespoonsunsweetened cocoa powder
Instructions
Preheat oven to 350 degrees. Grease one 8 or 9” cake pan well.
Whisk together cocoa, flour, sugar, baking soda, baking powder, and salt. Add 1/4 cup warm water, milk, yogurt, oil, and vanilla and stir until smooth (don’t overmix).
Pour batter into prepared pan. Bake, rotating once, until tester inserted in center comes out clean, about 18 minutes for a 9” pan.
Let cake cool in pan for 5 minutes before removing to cool completely. Alternatively, throw in the freezer until bottom is cold, then remove from pan.
To make frosting: stir the sugar and cocoa powder into the yogurt until smooth. This works best if you sift the cocoa powder first to avoid lumps, but is not necessary.
To assemble, cut cooled cake layer into six wedges. Spread frosting between layers and along the back of the cake, if you wish. I only used five wedges to make five layers and crumbled the remaining piece to decorate the back of the cake. You could also use the remaining layer to make a cake ball, or stamp into cake shapes, or eat.
Notes
The original recipe calls for an egg in this cake; I forgot it and happily it worked out since this is 1/6 of the original recipe. You can make this vegan by subbing additional milk or applesauce for the yogurt in the cake. You'd need to use another frosting altogether.
