Preheat your oven to 350°F and prep 2 6-inch cake pans with parchment paper and a touch of butter or spray.
In a big bowl, whisk together all the dry ingredients.
Add the egg and oil. Mix the milk with Ovaltine in a cup, then add it to the cake mixture. Whisk gently to combine.
Fold in the sour cream.
In another cup, mix boiling water with instant coffee, then whisk it into the cake mixture.
Divide the batter into the 6-inch pans and bake for around 30 minutes. Keep an eye on it, as baking times may vary.
For the ganache, chop the chocolate into a bowl. Heat the cream until it starts to boil, then pour it over the chocolate and gently mix after 3-5 minutes.
For the cream cheese frosting, combine all ingredients in a bowl and use a hand mixer to beat until light and creamy.
Once the cake is cooled, decorate with your frosting of choice, and voilà! Get ready to indulge in this chocolatey delight. Enjoy! 🎂🍫
