Calling all caramel and chocolate lovers—this Twix Cake is your dream dessert come to life!

Topped with dollops of frosting and real Twix candy pieces, it’s everything you love about the classic treat, baked into a stunning centerpiece cake.

The first time I made this Twix Cake for a birthday party, jaws dropped when it hit the table. It’s big, bold, and every bite delivers the perfect balance of chocolatey decadence and caramel bliss. If you’ve ever enjoyed our Snickers Cake or our Millionaire’s Shortbread Bars, this cake takes that candy bar indulgence and turns it into an unforgettable celebration. Let’s build the ultimate Twix-inspired dessert!

What is Twix Cake?

Twix Cake is a layered chocolate cake that mimics the flavors of a Twix candy bar: rich chocolate, buttery caramel, and a crunchy surprise from Twix pieces. This version features three moist chocolate cake layers, a caramel buttercream frosting, and generous drizzles of caramel and chocolate sauces. The final touch? Crowned with frosting swirls and chopped Twix bars for decoration and extra crunch.

Like the candy bar itself, it’s “crunchy, gooey, sweet, and impossible to resist.” But better—because it’s homemade.

Why You’ll Love This:

Here’s why this Twix Cake is more than just a pretty face:

• Triple chocolate cake: Rich, moist layers made with chocolate cake mix and enhanced with eggs and oil.
• Caramel frosting magic: Creamy, not-too-sweet, and beautifully balanced with vanilla and caramel.
• Candy bar topping: Twix pieces add texture and a fun surprise with every bite.

If you love layered cakes like our Oreo Chocolate Cake or Salted Caramel Cupcakes, this one delivers the same wow factor with an extra candy-coated twist.

How to Make Twix Cake

Quick Overview

This recipe is built in three parts: baking the chocolate cake layers, whipping up the caramel frosting, and assembling the cake with frosting, drizzles, and Twix pieces.

Ingredients:

For the Chocolate Cake:

• 2 boxes Triple Chocolate Cake Mix
• 6 large eggs
• 2½ cups water
• 1 cup canola oil
• 3 (9-inch) round cake pans
• 1 (10-inch) cake board
• Nonstick baking spray

For the Caramel Frosting:

• 2 cups unsalted butter, softened
• 5 cups powdered sugar
• 4–6 tbsp heavy whipping cream
• 2 tsp pure vanilla extract
• 4 tbsp caramel sauce

To Decorate:

• 1 bottle caramel sauce
• 1 bottle chocolate sauce
• Twix candy bars, chopped
• 1 large piping bag fitted with a star tip

Step-by-Step Instructions:

1. Bake the Chocolate Cake Layers

• Preheat oven to 350°F (175°C).
• Spray three 9-inch cake pans with nonstick baking spray.
• In a large bowl, combine cake mix, eggs, water, and oil.
• Beat using a hand mixer until smooth and combined (about 2 minutes).
• Divide batter evenly into the pans and bake for 28–35 minutes, or until a toothpick comes out clean.
• Let cakes cool in pans for 10 minutes, then turn out onto a wire rack to cool completely.

2. Make the Caramel Frosting

• In a stand mixer, beat butter until light and fluffy.
• Gradually add powdered sugar, mixing on low until combined.
• Add vanilla extract, caramel sauce, and heavy cream (start with 4 tbsp, add more if needed for consistency).
• Beat until frosting is smooth, creamy, and holds stiff peaks.

3. Assemble the Cake

• Level the tops of all cake layers using a cake slicer or serrated knife.
• Place the first layer onto the cake board.
• Spread 1 cup of caramel frosting evenly over the top.
• Repeat with the second cake layer and another cup of frosting.
• Add the final cake layer and use the remaining frosting to cover the top and sides of the cake.
• Use a frosting scraper or offset spatula to smooth the finish.

4. Decorate

• Warm the caramel and chocolate sauce slightly if needed for easier pouring.
• Pipe or spoon the caramel sauce around the top edge of the cake, letting it drip down the sides.
• Repeat with chocolate sauce.
• Fill a piping bag with leftover frosting and pipe decorative swirls around the top edge.
• Press chopped Twix bars into the frosting swirls for a candy bar crown.

What to Serve Twix Cake With

This indulgent cake pairs well with:

• A glass of milk or coffee to cut through the sweetness
• Vanilla ice cream for an extra treat
• Salted caramel drizzle for contrast
• Espresso or chocolate liqueur for an adult pairing

It’s perfect for birthdays, bake sales, or anytime you want to impress with a cake that looks and tastes amazing.

Top Tips for Perfecting This Cake

• Cool cake layers completely before frosting to prevent melting.
• Use an offset spatula and scraper for the smoothest frosting finish.
• Refrigerate before decorating if the frosting feels too soft—it firms up beautifully.
• Cut Twix bars just before using to keep them fresh and crunchy on the cake.
• Customize it! Add a layer of chocolate ganache or a surprise caramel filling between the layers for an extra twist.

Storing and Freezing Tips

• Refrigerate: Store covered in the fridge for up to 5 days. Let sit at room temp for 30 minutes before serving.
• Freeze: Wrap individual slices tightly in plastic wrap and freeze for up to 2 months. Thaw in the fridge overnight.
• Make ahead: You can bake and freeze the cake layers (unfrosted) in advance, then frost the day of serving.

FAQs

Can I use homemade chocolate cake instead of a mix?
Yes! Any sturdy, moist chocolate cake recipe will work.

You can fully assemble and decorate the cake up to 1 day in advance.

Do I need to refrigerate leftovers?
