Essential tools to make this recipe perfectly
This Milky Way Cake recipe isn’t just about throwing candy bars into a cake batter. It’s a carefully crafted combination of flavors and textures that work in perfect harmony. Here’s why it’s a winner:
- Moist Chocolate Cake: The foundation of this cake is a moist and tender chocolate cake, achieved through the use of buttermilk and oil. These ingredients contribute to a soft crumb and prevent the cake from drying out.
- Milky Way Infusion: Chopped Milky Way bars are incorporated into the frosting, providing that signature caramel-nougat flavor and a delightful textural contrast.
- Rich Caramel Frosting: The caramel frosting is made from scratch, using real caramel for an authentic and intense flavor. It perfectly complements the chocolate cake and Milky Way pieces.
- Decadent Chocolate Ganache: The chocolate ganache drizzle adds a final layer of richness and visual appeal. It’s the perfect finishing touch to this already amazing cake.
- Balanced Sweetness: While this cake is undoubtedly sweet, it’s not cloyingly so. The slight bitterness of the dark chocolate ganache helps to balance the sweetness of the caramel frosting and Milky Way bars.
Ingredients
For the Chocolate Cake:
- 2 cups all-purpose flour
- 2 cups granulated sugar
- ¾ cup unsweetened cocoa powder
- 1 ½ teaspoons baking powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt
- 1 cup buttermilk
- ½ cup vegetable oil
- 2 large eggs
- 2 teaspoons vanilla extract
- 1 cup hot coffee
For the Caramel Frosting:
- 1 cup (2 sticks) unsalted butter, softened
- 4 cups powdered sugar
- ½ cup heavy cream
- 1 teaspoon vanilla extract
- 1 cup caramel sauce (store-bought or homemade)
- 6-8 Milky Way bars, chopped
For the Chocolate Ganache:
- 4 ounces semi-sweet or dark chocolate, chopped
- ½ cup heavy cream

Instructions
Making the Chocolate Cake:
- Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
- In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
- In a separate bowl, combine the buttermilk, oil, eggs, and vanilla extract.
- Gradually add the wet ingredients to the dry ingredients, mixing until just combined.
- Slowly pour in the hot coffee, mixing until the batter is smooth. The batter will be thin.
- Divide the batter evenly between the prepared cake pans.
- Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
- Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.
Making the Caramel Frosting:
- In a large bowl, beat the softened butter with an electric mixer until light and fluffy.
- Gradually add the powdered sugar, one cup at a time, beating until smooth.
- Add the heavy cream and vanilla extract, and beat until light and fluffy.
- Stir in the caramel sauce until well combined.
- Gently fold in the chopped Milky Way bars.
Making the Chocolate Ganache:
- Place the chopped chocolate in a heatproof bowl.
- In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer.
- Pour the hot cream over the chocolate and let it sit for 1 minute.
- Whisk until smooth and glossy.
Assembling the Cake:
- Once the cakes are completely cool, level the tops with a serrated knife if necessary.
- Place one cake layer on a serving plate or cake stand.
- Spread a generous layer of caramel frosting over the cake layer.
- Top with the second cake layer.
- Frost the entire cake with the remaining caramel frosting.
- Drizzle the chocolate ganache over the top of the cake, allowing it to drip down the sides.
- Optional: Decorate with extra chopped Milky Way bars.
- Refrigerate for at least 30 minutes to allow the frosting to set before serving.
Tips for Success
- Use Room Temperature Ingredients: Using room temperature ingredients, especially the butter and eggs, will help the cake batter come together smoothly and evenly.
- Don’t Overmix the Cake Batter: Overmixing can develop the gluten in the flour, resulting in a tough cake. Mix until just combined.
- Cool the Cakes Completely: Make sure the cakes are completely cool before frosting them. Otherwise, the frosting will melt.
- Use a Good Quality Caramel Sauce: The quality of the caramel sauce will affect the flavor of the frosting. If you’re using store-bought caramel sauce, choose a good brand. Homemade caramel sauce is even better!
- Adjust Sweetness to Your Liking: If you prefer a less sweet cake, you can reduce the amount of sugar in the cake batter or the frosting.
- Chill the Cake Before Serving: Chilling the cake for at least 30 minutes before serving will allow the frosting to set and make it easier to slice.
Storage Instructions
Store the Milky Way Cake in an airtight container in the refrigerator for up to 3-4 days. The cake is best served cold or at room temperature. You can also freeze individual slices of cake for up to 2 months. Thaw in the refrigerator overnight before serving.

FAQ
- Can I use a different type of chocolate for the ganache? Yes, you can use milk chocolate or white chocolate for the ganache. Keep in mind that milk chocolate will result in a sweeter ganache.
- Can I make the cake ahead of time? Yes, you can bake the cake layers a day or two ahead of time. Wrap them tightly in plastic wrap and store them at room temperature. You can also make the caramel frosting ahead of time and store it in the refrigerator for up to 3 days. Bring it to room temperature and beat it with an electric mixer before using.
- Can I use a different type of candy bar? While this recipe is specifically for Milky Way Cake, you could experiment with other candy bars like Snickers or Twix. Just be sure to adjust the amount of candy bar to your liking.
- My cake is dry. What did I do wrong? Overbaking is the most common cause of dry cake. Be sure to check the cake for doneness with a toothpick. Also, make sure you are using the correct amount of liquid ingredients.
