Caramel Cream Poke Cake

box yellow cake mix (I used Duncan Hines but you can use this scratch recipe)

heavy cream

ounces caramel sundae topping (I just eyeball it and use half of one 12-ounce jar)

whipped topping, thawed (I used fat-free)

about 1/3 cup salted caramel sauce, for drizzling (storebought or homemade, regular caramel sauce may be substituted)
