How To Make Martha Stewart Dark Chocolate Cake
- Preheat and prep pan: Preheat oven to 350°F. Butter or spray a 9–10 inch cake pan and line with parchment paper.
- Mix dry ingredients: In a small bowl, whisk together cocoa powder, baking powder, flour, and salt. Set aside.
- Melt chocolate and butter: In a small saucepan over medium-low heat, melt butter and dark chocolate, stirring until smooth.
- Make the batter: Transfer melted mixture to a large mixing bowl and let cool for 5 minutes. Whisk in oil, sugar, vanilla, and Greek yogurt. Add eggs and mix well.
- Combine with dry ingredients: Add the dry mixture and whisk until smooth and fully combined.
- Bake the cake: Pour batter into the prepared cake pan and bake for 40–50 minutes, or until a toothpick inserted in the center comes out clean.
- Cool completely: Let the cake cool fully in the pan, then transfer to a wire rack.
- Make and apply frosting: Mix hot water, butter, cocoa powder, icing sugar, and a pinch of salt until smooth. Frost the top of the cooled cake in a swirling pattern.

Recipe Tips
- Can I use milk chocolate instead? Dark chocolate is preferred for richness, but milk chocolate can be used for a milder flavor.
- Why use Greek yogurt? It keeps the cake moist and adds a slight tang to balance the chocolate.
- How do I avoid overbaking? Start checking at 40 minutes and use a toothpick to test doneness.
- Can I double the frosting? Yes, if you want to frost the sides as well.
- Can this cake be made ahead? Yes, bake and cool it a day in advance. Frost just before serving.
