This chocolate Snickers cake is everything you want in a birthday dessert: rich, moist chocolate layers, creamy peanut butter frosting, a hidden pocket of peanut caramel, and a glossy milk chocolate ganache.
I will walk you through each step so you can build this impressive layer cake with confidence. The process has seven main parts, and I promise the payoff is worth every minute.
Step 1: Bake the Chocolate Cake Layers
Preheat your oven to 350°F (175°C). Line four 8 inch cake pans with parchment and spray the sides. In a large bowl, sift together the dry ingredients:
2 1/2 cups all purpose flour
2 1/2 cups granulated sugar
1 cup unsweetened cocoa powder
2 1/2 teaspoons baking powder
2 teaspoons baking soda
1 teaspoon salt
In another bowl, whisk together the wet ingredients:
1 1/4 cups warm water
1 1/4 cups buttermilk
2/3 cup vegetable oil
3 large eggs
2 teaspoons vanilla extract
Combine the wet and dry mixtures and stir just until smooth. Divide the batter evenly among the pans (about 450g per pan). Bake for 22 to 25 minutes, until a toothpick inserted in the center comes out with moist crumbs. Let the layers cool in the pans for 10 minutes, then pop the pans into the freezer for 30 minutes to lock in moisture. (You can also cool them on a wire rack.) Remove the layers and level them with a serrated knife if needed. If you make the layers ahead, thaw them for 15 minutes before assembling.
Step 2: Make the Peanut Caramel
This is a dry caramel method, and it is simpler than it sounds. Place a saucepan over medium heat. Add 2 cups of granulated sugar, a quarter cup at a time, stirring with a rubber spatula. Wait until each addition is mostly liquefied before adding the next. Continue until the sugar is fully dissolved and turns a deep amber color. Remove the pan from the heat and slowly mix in 3/4 cup of unsalted butter (room temperature). Then stir in 1/2 cup heavy cream and 1/2 teaspoon salt. The mixture will be thin but will thicken as it cools. Let it cool to room temperature, then whip it with a hand mixer or stand mixer with a whisk attachment for 1 to 2 minutes until lighter and thicker. Set aside about 1/3 cup in a piping bag for the drips. Fold 3/4 cup salted chopped peanuts into the remaining caramel.
Tip: Whip the cooled caramel to make it airy and easier to spread between cake layers.
Step 3: Make the Peanut Butter Buttercream Frosting
This American buttercream comes together quickly. Beat 1 1/2 cups (3 sticks) unsalted butter (room temperature) and 1 cup creamy peanut butter on medium high for 1 minute. Mix in 1 teaspoon vanilla and 1/2 teaspoon salt.
Gradually add 7 cups of powdered sugar and 2/3 cup heavy cream on low speed. Adjust the consistency with a little extra cream or powdered sugar if needed. You can make this frosting up to a month in advance and store it in the fridge.
Step 4: Stack and Fill the Cake Layers
Place the first cake layer on a greaseproof cake board with a dab of buttercream to hold it in place. Spread an even layer of buttercream over the top, then pipe a ring of buttercream around the edge to create a dam.
Fill the center with one third of the peanut caramel. Repeat with the next two layers. Flip the top layer upside down so the flat side faces up for easier frosting and less crumbing.
Step 5: Chill and Frost the Cake
Place the stacked cake in the freezer for 5 to 10 minutes so the layers set and won’t slide.
Then apply the remaining peanut butter buttercream all over the cake, smoothing it with a bench scraper or large offset spatula. Chill the cake again in the fridge for 30 minutes (or 10 minutes in the freezer) until the frosting firms up.
Step 6: Make the Chocolate Ganache Drip & Decorate This Snickers Cake
Heat 1/3 cup heavy cream in a microwave safe bowl for 30 to 45 seconds until just bubbling. Pour 1/2 cup milk chocolate chips into the cream, making sure they are fully covered.
Let sit for 1 minute, then stir until smooth. If the ganache is too thick, add a splash more cream; if too thin, stir in a few extra chips. For a dark chocolate version, use 2/3 cup cream and 1/2 cup dark chocolate chips.
Step 7: Decorate the Chocolate Snickers Cake
Drizzle the reserved caramel from the piping bag over the edge of the chilled cake.
If the caramel is too thick, warm it in the microwave in 5 second intervals. Then pour the chocolate ganache on top and gently push it over the edge with a small offset spatula.
Press chopped peanuts around the base of the cake.
Add a ring of chopped mini Snickers bars around the top and sprinkle with a pinch of flaky sea salt. Enjoy!
You can adapt this chocolate cake recipe to fit different diets. Here are the best swaps:
Flour: Use a good gluten free baking flour blend. Stir the batter a little longer and let it sit for 20 minutes before baking.
Sugar: Do not reduce or change the granulated sugar; it is essential for structure and moisture.
Cocoa: Any brand of unsweetened baking cocoa works. Dark or black cocoa will deepen the chocolate flavor.
Buttermilk: Substitute with full fat yogurt, sour cream, whole milk, or a non dairy milk.
Oil: Use any neutral oil like canola, vegetable, or sunflower. Avoid olive oil.
Eggs: A vegan egg replacer can work, but large eggs give the best texture.
Substitutions and Swaps, Peanut Butter Buttercream
This frosting is flexible too. If you use salted butter, leave out the added salt. Vegan butter also works. Be sure to use creamy, shelf stable peanut butter like Jif or Skippy; natural peanut butter can cause the frosting to break. Heavy cream can be swapped with whipping cream, coconut cream, or a non dairy milk. Vanilla extract is optional, or you can use almond or coconut extract for a twist.
Making This Snickers Layer Cake in Different Sizes
One batch of batter weighs about 1800g. For four 8 inch pans, add roughly 450g per pan. The same batch can make two 9 inch layers or four 6 inch layers (bake a few minutes longer at 350°F). For Snickers cupcakes, fill liners 3/4 full and bake for 18 to 21 minutes at 350°F; you will get about three dozen. If you need a tiered cake, use a cake batter calculator to determine how many batches you need.
Can This Chocolate Snickers Cake Be Made in Advance?
Absolutely. Bake the cake layers ahead and freeze them; they taste great straight from the freezer.
The frosting can be stored in an airtight container in the fridge for up to a month; just stir it after thawing. A fully frosted cake keeps in the fridge for up to a week. Leftover cut cake can also be stored for a week if you cover the cut section with the remaining frosting.

Sift dry ingredients (flour, sugar, cocoa, baking powder, baking soda, salt), whisk wet ingredients (water, buttermilk, oil, eggs, vanilla), combine, divide batter evenly. Bake 22-25 minutes until a toothpick comes out with moist crumbs. Cool in pans 10 minutes, then freeze 30 minutes before leveling.
2-Make the Peanut Caramel: Make a dry caramel: melt sugar in a saucepan over medium heat, adding a quarter cup at a time and stirring until fully dissolved and amber. Remove from heat, stir in butter, heavy cream, and salt. Cool, then whip with a mixer until light and thick. Reserve 1/3 cup for drips; fold 3/4 cup chopped salted peanuts into the remainder.
3-Make the Peanut Butter Buttercream Frosting: Beat room-temperature butter and creamy peanut butter until smooth. Add vanilla and salt, then gradually beat in powdered sugar and heavy cream until fluffy. Adjust consistency with extra cream or sugar if needed.
4-Stack and Fill the Cake Layers: Place first layer on a cake board with a dab of buttercream. Spread a layer of buttercream, pipe a dam around the edge, and fill the center with one-third of the peanut caramel. Repeat with next two layers. Flip the top layer upside down for a flat surface.
