How to Make Chocolate Layer Twix Cake Recipe
Step 1: Prepare and Bake the Cake Layers
Start by preheating your oven as directed on the cake mix boxes—typically around 350°F. In a large bowl, combine the two boxes of triple chocolate cake mix with six eggs, 2 ½ cups of water, and 1 cup of canola oil. Whisk everything until the batter is smooth and glossy with no lumps. Divide the batter evenly between two greased and floured 9-inch round cake pans, smoothing the tops with a spatula. Bake for about 30 to 31 minutes, or until a toothpick inserted in the center comes out clean. Once baked, allow the cakes to cool completely on wire racks before you move on.
Step 2: Make the Frosting
While the cake is cooling, get started on the frosting. Cream the softened butter in a large bowl until it’s light and fluffy—this takes about 3 to 4 minutes with an electric mixer. Gradually add in the powdered sugar, alternating with heavy whipping cream to keep the mixture creamy but firm enough to spread. Stir in the pure vanilla extract for a burst of warm flavor. The frosting should be smooth and luxurious, perfect for layering and topping your cake.
Step 3: Assemble Your Chocolate Layer Twix Cake Recipe
Place one cake layer on your serving plate or cake stand and generously spread a thick layer of frosting on top. Drizzle caramel sauce evenly over the frosting, letting it melt into the layers slightly, enhancing that gooey caramel goodness. Add the second cake layer on top and frost the entire cake with a thin crumb coat to lock in crumbs. Refrigerate for 15 minutes, then apply the final layer of frosting smoothly around the cake. To finish, drizzle chocolate sauce artistically over the top and sides, then sprinkle crushed Twix bars to decorate, giving the perfect crunchy nod to the candy bar inspiration. Chill the cake if possible before serving to let everything settle beautifully.
How to Serve Chocolate Layer Twix Cake Recipe

Garnishes
For that extra wow factor, garnish your cake with whole or halved Twix bars around the edges or on top. A sprinkle of sea salt can heighten the caramel’s flavor if you enjoy a sweet-salty contrast. Fresh raspberries or strawberries can also add a pop of color and a slight tanginess that complements the rich chocolate layers.
Side Dishes
This Chocolate Layer Twix Cake Recipe is rich and indulgent, so pairing it with light accompaniments works beautifully. Serve it alongside a scoop of vanilla bean ice cream or a dollop of freshly whipped cream to provide a creamy contrast. If you want to keep things lighter, a simple fruit salad or a hot cup of coffee or tea can balance the sweetness perfectly.
Creative Ways to Present
For a unique presentation, slice your cake into bars and place individual portions in decorative cupcake liners topped with a drizzle of extra caramel and chocolate. This is perfect for gatherings where guests can grab and go. Another creative touch is to serve small squares alongside a tasting spoon of caramel or chocolate sauce for dipping—trust me, everyone will love the playful interaction!
Make Ahead and Storage
Storing Leftovers
Leftover cake should be tightly covered with plastic wrap or stored in an airtight container to keep it moist and fresh. Refrigerate any leftovers, especially because of the caramel and frosting, and consume within 3 to 4 days for the best taste and texture.
Freezing
This cake freezes wonderfully! Wrap the entire cake or individual slices in plastic wrap followed by aluminum foil to prevent freezer burn. You can keep it frozen for up to three months. When you’re ready to enjoy, thaw overnight in the refrigerator before serving.
Reheating
Because it’s best served chilled or at room temperature, avoid microwaving the cake. Instead, allow it to sit out for about 30 minutes after refrigeration to bring the flavors and textures back to their ideal state.
FAQs
Can I make this cake without the cake mix?
Absolutely! If you prefer homemade cake from scratch, choose a rich chocolate cake recipe with cocoa powder and substitute accordingly to maintain the deep chocolate flavor. Just keep in mind the baking times might vary.
How many Twix bars should I crush for the topping?
Using about 4 to 6 standard-sized Twix bars will give you enough crunchy bits to generously decorate the cake and add texture without overwhelming each slice.
Is there a way to make this cake less sweet?
Yes, you can slightly reduce the powdered sugar in the frosting or use a bittersweet chocolate sauce rather than a milk chocolate one. Adding a pinch of salt in the caramel or frosting can also balance the sweetness nicely.
Can I use salted butter in the frosting?
You can, but reduce any added salt in your other ingredients. Unsalted butter is preferred to control the salt level and keep the flavors balanced.
What’s the best way to cut this cake cleanly?
Use a sharp serrated knife and wipe it clean between each cut to keep slices neat and prevent crumbs from smudging the frosting.
