Why You Will Love This Cake
- Smaller Size: I love having a smaller recipe for when we need a cake for our family, but don’t want a lot leftover.
- Moist: The crumb of this cake is so soft, it practically melts in your mouth.
- Chocolate Ganache: The ganache is so rich and fudgy without being overly sweet.
Ingredient Notes
Full ingredient measurements and instructions can be found in the recipe card below.
- Cocoa Powder– A dutch processed cocoa powder will give this cake an extra rich chocolate flavor.
- Oil– I love using melted coconut oil, but any neutral oil is great.
- Egg– Make sure your egg is room temperature.
- Buttermilk– You can sub in regular milk if needed. Keep in mind the higher the fat in your milk, the more moist the cake.
- Water/Coffee– If using coffee it will not make your cake taste like coffee, it just helps to enhance the chocolate flavor.
Step by Step Instructions
- Step 1: In a large bowl, sift or stir together flour, both sugars, cocoa powder, baking soda, baking powder, and salt.
- Step 2: In a mixing bowl, beat oil, eggs, buttermilk, and vanilla together until completely mixed. About 1 minute. Slowly add dry ingredients into wet ingredients while mixing. Pour in hot water/coffee and mix together another minute. It’s ok if the batter seems extra liquidy.
- Step 3: Pour batter into prepared pan. Bake for about 28-33 minutes. When toothpick placed in the center of the cakes comes out clean, you know it is done.
- Step 4: Place chocolate chips in a medium bowl. Heat whipping cream and powdered sugar until barely starting to boil and then pour over chocolate chips. Add in vanilla and butter and mix until smooth. Allow to sit for about 20 minutes until starting to thicken.
- Step 5: Cover the ganache and place in the fridge for about 20-30 more minutes to firm up.
- Step 6: Top cake with chocolate ganache frosting and a sprinkle of flaked salt or some chocolate shavings.
Expert Baking Tips
- Cake will have the best results if made with room temperature ingredients. I like to pull my eggs, buttermilk, and butter out of the fridge an hour or two before I start baking.
- If you prefer a buttercream for topping I would suggest using my chocolate buttercream.
- I have given both cups and grams as measurements. Grams will be more precise, especially when measuring flour. If you don’t have a kitchen scale, no problem! Just lightly spoon flour into your measuring cup to insure its not packed in there. Light and fluffy is the key.
FAQ

Yes, add 2 teaspoon of vinegar to your milk, stir and allow to sit for 5 minutes to curdle. It will not be the same as buttermilk, but is a great alternative.
