Grandma Jean's Buttermilk-Chocolate Cake
This moist and delicious buttermilk-chocolate cake is my grandma's best recipe and I have made it countless times.
Use decaf or regular coffee. If you don't have buttermilk, you can make sour milk by mixing 1 tablespoon white vinegar or lemon juice with regular whole milk.
You can use two 9-inch round cake pans, if preferred, just change bake time to 30 to 35 minutes.
