How to Make Chocolate Layer Twix Cake Recipe
Step 1: Bake the Cake Layers
Start by preheating your oven to 350°F (175°C), then prepare two 9-inch round cake pans by greasing and flouring them lightly. In a large mixing bowl, combine the triple chocolate cake mix with eggs, water, and canola oil. Beat the batter just until smooth to avoid overmixing, which keeps your cake tender. Divide the batter evenly between the pans and pop them into the oven for about 31 minutes. Once baked, let the layers cool completely on a wire rack before moving to the next step.
Step 2: Make the Buttercream Frosting
While the cake cools, whip up the frosting. In a stand mixer or with a hand mixer, beat the softened butter until creamy and smooth. Gradually add the powdered sugar, mixing on low speed to prevent a sugar cloud. Add the heavy cream and vanilla extract, increasing the speed to medium-high, until you get a fluffy, spreadable buttercream. Taste and add more vanilla or cream as needed to reach your favorite texture and flavor balance.
Step 3: Assemble the Cake
Place one cake layer onto your serving plate and start by spreading a generous layer of buttercream over the top. Drizzle caramel sauce evenly and sprinkle chopped Twix bars for that irresistibly crunchy surprise. Add the second cake layer on top and repeat the process. Finally, frost the entire cake with the remaining buttercream. For a dramatic finish, drizzle chocolate and more caramel sauces over the top, then garnish with more chopped Twix bars. Chill the cake for at least an hour before slicing to let everything set beautifully.
How to Serve Chocolate Layer Twix Cake Recipe

Garnishes
Garnishing your Chocolate Layer Twix Cake Recipe is your chance to add extra personality. Consider adding whole or halved Twix bars around the edges for instant wow factor. A light sprinkle of sea salt flakes on the caramel drizzle will heighten the flavors and balance the sweetness. Fresh raspberries or strawberries also pair surprisingly well, adding just the right pop of color and slight tartness.
Side Dishes
This cake stands well on its own, but a scoop of vanilla bean ice cream or a dollop of freshly whipped cream makes for a perfect companion. If you want to elevate the experience, serve alongside a cup of rich, freshly brewed espresso or hot chocolate to complement all the decadent chocolate, caramel, and cookie flavors.
Creative Ways to Present
Want to impress your guests? Slice the cake into small, elegant squares and serve on individual dessert plates with a caramel drizzle and a mini Twix bar on the side. Alternatively, turn slices upside down and layer with whipped cream and fresh fruit in a clear glass for a decadent layered parfait style presentation. This cake shines whether it’s the centerpiece of a birthday party or a cozy weekend treat.
Make Ahead and Storage
Storing Leftovers
Leftover Chocolate Layer Twix Cake Recipe can be kept covered at room temperature for up to two days, but for best texture and flavor, store it in an airtight container in the refrigerator for up to five days. This keeps the frosting fresh and the cake layers moist without drying out or getting soggy.
Freezing
If you want to save this cake for later, wrap it tightly in plastic wrap and then aluminum foil before placing it in the freezer. The cake will keep well for up to two months. When you’re ready to enjoy it, thaw overnight in the refrigerator to preserve the texture and flavors.
Reheating
Because this cake is rich and made mostly of frosting and candy, reheating isn’t necessary or recommended. If you’d like to soften it slightly, leaving a slice at room temperature for 30 minutes before serving is ideal. This way, you get the best creamy and indulgent experience without melting the toppings.
FAQs
Can I substitute the cake mix with a homemade chocolate cake?
Absolutely! While the triple chocolate cake mix makes this recipe super convenient, a moist homemade chocolate cake base will work perfectly too. Just be sure your homemade cake layers bake evenly and stay moist for the best results.
What type of caramel sauce works best for this cake?
Look for a thick, rich caramel sauce—something that isn’t too runny so it stays put between layers but still melts in your mouth. A good-quality store-bought sauce or homemade caramel will both elevate the cake beautifully.
Can I use other candy bars instead of Twix?
While Twix bars are the star here thanks to their caramel and cookie layers, you can experiment with other favorites like Snickers or Heath bars for a unique twist. Just keep in mind the textures and flavors will change slightly.
How do I ensure my cake layers stay perfectly moist?
Use the exact oil and water measurements in this recipe, and avoid overbaking by checking for doneness with a toothpick. Also, don’t skip the buttercream layer as it adds moisture and richness between the cake layers.
Is this recipe suitable for large gatherings?
Definitely! This recipe yields 12 generous slices, and the cake’s impressive look and flavor make it a crowd-pleaser. You can easily double the ingredients to make a bigger cake for bigger celebrations.
