Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan.
In a large mixing bowl, combine the Devil’s Food cake mix, sweetened condensed milk, mayonnaise, strong hot coffee, cocoa powder, eggs, and vanilla extract.
Mix well using a hand mixer or whisk until smooth and well combined. Fold in the crushed Skor bars gently to distribute them throughout the batter.
Pour the batter into the prepared baking pan, spreading it out evenly. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
Let the cake cool completely in the pan on a cooling rack. Once the cake has cooled, drizzle the sweetened condensed milk over the top of the cake.
Next, drizzle the chocolate sauce over the cake. You can reserve a portion of the sauce for serving. Sprinkle the toffee bits evenly over the cake. Finally, drizzle the caramel sauce over the toffee bits and chocolate sauce.
Slice the cake into pieces (approximately 12 servings) and enjoy! Optionally, serve with additional chocolate sauce or whipped cream for extra indulgence.
