To prepare a vanilla birthday cake caramel cream recipe, you will first need to prepare the cake batter. Place the butter, sugar, vanilla, and eggs into the mixing bowl. Beat the mixture with an electric mixer until light and fluffy, about 5 minutes. Add the flour, baking powder, salt, nutmeg and baking soda and beat until the ingredients are well combined. Pour the batter into an ungreased 8-inch round cake pan and bake in the oven at 350? for 35 to 40 minutes, or until toothpick inserted in center comes out clean. Let cake cool in pan for 10 minutes before removing to wire rack to cool completely.
