I have always used this recipe and this turns out really soft and moist, but also crumbly. How can I fix it?
Here are the ingredients:
1 1/2 cups (3 sticks) unsalted butter, room temperature, plus more for pans
3/4 cup Dutch-process cocoa powder, sifted, plus more for pans
3/4 cup hot water
3/4 cup sour cream
3 cups cake flour, (not self-rising), sifted
1 teaspoon baking soda
1/2 teaspoon salt
2 1/4 cups sugar
4 large eggs
1 tablespoon pure vanilla extract
I haven't used up all the batter yet, so I can do changes if required. Please help!
