Yellow cake is a classic light, fluffy cake that uses only egg yolks to create a golden yellow hue crumb. This post shows you how to make the best Yellow Cake with Chocolate Fudge Frosting.
Preheat the oven to 350F. Grease and line the cake pans with parchment paper. Set them aside.
Sift all dry ingredients, and set them aside.
2¾ cups All-purpose flour, 2 teaspoon Baking powder, ½ teaspoon Baking soda, ¼-½ teaspoon Tumeric powder, ½ teaspoon Salt
Beat the room-temperature Butter and Sugar until creamy and light.
½ cup Butter, 1½ cup Sugar
Add the Oil and Sour Cream and mix.
½ cup Oil, ¼ teaspoon Sour cream
Next, add the eggs and yolks one at a time and beat after each addition. Add Vanilla extract and mix.
3 Yolks, 3 Eggs
Start adding the dry ingredients alternating with buttermilk. Start and finish with dry ingredients. Do not overmix.
1 cup Buttermilk
Pour the batter into the prepared pans, and bake them for 25- 30 minutes. Let the cakes cool down in the pan for 10 minutes, then flip them on a cooling rack. Let them cool fully before frosting.
How To Make The Frosting
Bring the heavy cream to a simmer, on the stove or in the microwave. Let the chocolate sit in the hot cream for five minutes, then stir the mixture until the chocolate is melted and the mixture is smooth and shiny.
1 cup Heavy cream, 9 ounce Semi-sweet chocolate
Pour the mixture into the stand mixer bowl, then mix in the brown sugar, melted butter, cocoa powder, vanilla extract and sour cream.
¼ cup Dark brown sugar, 2 tablespoon Cocoa powder, 1 tablespoon Butter, ⅓ cup Sour cream, 1 tablespoon Vanilla extract
Place the bowl in the fridge for 15-30 minutes. Different kinds of chocolate react differently in the fridge. The mixture should become thicker and have the consistency of Greek yogurt. Check the mixture after 15 minutes, and if it is still runny, place it back in the fridge for another five minutes.
Place the bowl under the whisk attachment and whisk it until it is thick and spreadable. Frost the cake layers; know that this frosting will become thicker as it sets.
