For the cake

• In a large bowl, add the softened butter and white sugar. With an electric mixer, cream on medium speed for 2-3 minutes until light and fluffy.
  1/2 cup unsalted butter, 3/4 cups dark brown sugar
• Add in the molasses, eggs, vanilla, milk, jam, and sour cream. Cream together for 2-3 minutes to combine, it's okay if it looks chunky!

• With a spatula, mix together the dry and wet ingredients until a soft cake batter forms. Do not over-mix!
