Bake the chocolate cake mix as directed on the box. Once it is out of the oven and baked, cool completely.
15.25 ounces chocolate cake mix, 1¼ cups water, ½ cup vegetable oil, 3 large eggs
Once cooled, create small holes throughout the entire cake with the back of a narrow mixing spoon. Be sure to not poke all the way through the cake. Set aside.
In a small bowl combine the sweetened and condensed milk, ½ teaspoon vanilla extract, cinnamon, nutmeg, and salt. Stir until combined.
14 ounces sweetened condensed milk, 1 teaspoon pure vanilla extract, ½ teaspoon ground cinnamon, ¼ teaspoon ground nutmeg, ½ teaspoon kosher salt
Pour the sweetened and condensed milk mixture over the cake. The mixture should fill all the holes created previously.
Chill in the refrigerator for 30-60 minutes for best results.
While the cake is chilling, make the whipped cream: In a large bowl combine the heavy whipping cream, powdered, sugar, and ½ teaspoon vanilla extract. Using a hand mixer, beat the mixture on high until it thickens and has the consistency of whipped cream, about 3-5 minutes.
1½ cups heavy whipping cream, 2 tablespoons powdered sugar
Using a spatula or other tool, spread the whipped cream over the entire cake in an even layer, then drizzle the caramel sauce and toffee bits evenly over the cake, optional.
