Step-by-Step Instructions
These detailed instructions will guide you through baking, soaking, and decorating your Better Than Sex Cake.
Preparing the Cake Base
Preheat the oven to 350°F (175°C). Grease your 9×13 baking dish thoroughly. In a large bowl, prepare the Devil’s food cake batter according to the box instructions by combining the cake mix with eggs, oil, and water.
Mix just until combined to avoid overworking the batter. Pour the batter into the prepared pan and bake for 28–33 minutes or until a toothpick inserted into the center comes out clean. Remove from oven and let cool slightly for 10 minutes.
Infusing the Cake
Using the handle of a wooden spoon or a skewer, poke holes evenly all over the surface of the warm cake without piercing all the way through.
Pour the sweetened condensed milk slowly over the cake, allowing it to seep into the holes. Next, drizzle the caramel ice cream topping evenly over the cake so it fills the gaps, creating a luscious, sticky texture. Let the cake cool completely in the pan.
Final Decoration and Topping
For the freshest taste, consider whipping your own heavy cream instead of using pre-made Cool Whip. To make homemade whipped cream, whip chilled heavy cream with powdered sugar and a pinch of dry milk powder until stiff peaks form.
Spread the whipped cream evenly over the cooled cake using an offset spatula or pipe decorative swirls with a piping bag. Generously sprinkle chopped Heath bar pieces on top, and finish with a drizzle of caramel sauce and, if desired, chocolate sauce. Chill the cake for at least one hour before slicing to allow the flavors to meld and the texture to set.
Tips for Perfect Results
To ensure your Better Than Sex Cake is as indulgent and flawless as possible, follow these expert tips:
-
Cool Completely Before Topping: Prevent whipped cream from melting and sliding by allowing the cake to cool fully after soaking.
-
Use Quality Ingredients: Invest in a rich chocolate cake mix, premium sweetened condensed milk, and thick caramel sauce for maximum flavor.
-
Poke Deep Holes: Make sure holes penetrate deeply to let the creamy sauce soak throughout the cake, not just on top.
-
Homemade Whipped Cream Option: For fresher taste and better texture, whip your own cream instead of using store-bought toppings.
-
Chill Thoroughly: Refrigeration for at least one hour enhances the melding of flavors and ensures clean slicing.
-
Customize Toppings: Add extra Heath bits, toffee pieces, or a dusting of cocoa powder for personalized flair.
Make-Ahead and Storage Tips
Planning ahead makes enjoying this decadent cake even easier.
-
Prepare in Advance: Assemble the cake up to one day before serving. Store tightly covered in the refrigerator to keep it moist and fresh.
-
Storage: Leftovers stay fresh for up to 5 days refrigerated in an airtight container. The cake’s flavors intensify after resting.
-
Freezing: If desired, freeze individual slices wrapped in plastic and foil for up to 2 months. Thaw overnight in the fridge before serving.
