Ingredients Overview

This cake has a few moving parts, but each layer brings essential texture and flavor. Here’s what you’ll need and how to make smart swaps if needed.

Chocolate Cake Layers:
Made with cocoa powder and buttermilk, these layers are rich, moist, and tender. Using oil instead of butter keeps the crumb soft and light. A touch of hot coffee intensifies the chocolate flavor without making the cake taste like coffee.

All-Purpose Flour:
Gives structure and holds up the heavy fillings. You can substitute with cake flour for a lighter texture, but all-purpose works beautifully here.

Unsweetened Cocoa Powder:
Choose a high-quality Dutch-processed or natural cocoa powder for deep chocolate flavor. Sift it well to avoid lumps.

Baking Powder & Baking Soda:
Both leavening agents work together to ensure the cake rises evenly and has a soft crumb.

Buttermilk:
Provides tang and moisture. If you don’t have it, use regular milk with a splash of vinegar or lemon juice.

Vegetable Oil:
Adds richness and helps keep the cake moist for days. Canola oil or light olive oil also works.

Eggs:
Bind the ingredients and provide structure. Room temperature eggs incorporate more evenly.

Granulated Sugar & Brown Sugar:
A mix of both gives the cake sweetness and a slight molasses depth.

Vanilla Extract:
Enhances the overall flavor and rounds out the chocolate notes.

Hot Coffee or Water:
Used to bloom the cocoa and deepen flavor. Coffee is ideal but hot water works too.

Nougat Filling:
A creamy, whipped mixture of marshmallow crème, peanut butter, and powdered sugar. It’s light, fluffy, and mimics the Snickers candy’s interior.

Salted Caramel Sauce:
Homemade or store-bought caramel adds gooey richness between the layers. The salt balances the sweetness.

Roasted Salted Peanuts:
Chopped for texture and crunch. They give each bite that signature Snickers feel.

Chocolate Ganache:
Made with heavy cream and semi-sweet chocolate for a glossy, smooth frosting. It ties everything together without overwhelming the other flavors.

Step-by-Step Instructions

Step 1: Make the Chocolate Cake
Preheat oven to 350°F (175°C). Grease and line three 8-inch round cake pans with parchment.

In a large bowl, whisk together 2 cups all-purpose flour, ¾ cup unsweetened cocoa powder, 2 tsp baking powder, 1 tsp baking soda, and ½ tsp salt.

In another bowl, whisk 1 cup buttermilk, ¾ cup vegetable oil, 3 large eggs, 1 tsp vanilla extract, 1 cup granulated sugar, and ¾ cup brown sugar until smooth.

Gradually stir the dry ingredients into the wet mixture. Then pour in ¾ cup hot coffee (or water) and mix until the batter is smooth and slightly thin.

Divide the batter evenly among the pans. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out with moist crumbs.

Cool the cakes in the pans for 10 minutes, then turn out onto wire racks to cool completely.

Step 2: Make the Nougat Filling
In a large mixing bowl, beat 1 cup marshmallow crème with ½ cup creamy peanut butter until fluffy.

Add 1½ cups powdered sugar and beat until well combined and thickened. If too thick, add 1–2 tablespoons milk to reach spreadable consistency.

Step 3: Prepare the Caramel and Peanuts
Warm 1 cup salted caramel sauce (homemade or store-bought) just until pourable. Chop 1 cup roasted salted peanuts and set aside.

Step 4: Make the Chocolate Ganache
Heat 1 cup heavy cream in a small saucepan until just simmering.

Pour over 8 oz chopped semi-sweet chocolate in a bowl. Let sit for 2–3 minutes, then stir until smooth and glossy. Cool until it thickens to a spreadable consistency.

Step 5: Assemble the Cake
Place one cake layer on a serving plate or cake board. Spread a layer of nougat filling, drizzle with caramel, and sprinkle with chopped peanuts.

Repeat with the second layer. Add the third cake layer on top.

Spread ganache over the top and sides of the cake. For a clean finish, chill the cake for 20 minutes before smoothing the ganache.

Step 6: Decorate
Drizzle more caramel over the top and garnish with extra chopped peanuts or mini Snickers pieces if desired.

Refrigerate the cake for at least 1 hour to help the layers set before slicing.

Tips, Variations & Substitutions

Practical Tips:

• Chill the cake between steps if the fillings begin to ooze out.

• Use a cake leveler or serrated knife to trim domed layers for a neater stack.

• For easier ganache application, let it cool to peanut butter consistency.

Flavor Variations:

• Swap peanut butter with almond butter in the nougat for a different nutty note.

• Use dark chocolate in the ganache for a more intense, less sweet finish.

• Add chopped Snickers candy between the layers for extra texture and flavor.

Substitutions:

• No buttermilk? Combine 1 cup milk with 1 tbsp vinegar or lemon juice.

• No marshmallow crème? Melt mini marshmallows with a splash of milk and cool slightly before mixing with peanut butter.

• Nut-free? Skip the peanuts and use sunflower seed butter or cookie butter in the nougat.

Texture Boosters:

• Add a thin layer of crushed pretzels for a salty crunch.

• Swirl caramel directly into the cake batter before baking for caramel-streaked slices.

Serving Ideas & Occasions

Chocolate Snickers Cake is the ultimate dessert for celebrations. With its impressive layers and rich flavor, it’s perfect for birthdays, holidays, potlucks, or anytime you want to wow a crowd.

Serve chilled or at room temperature with a cold glass of milk or a hot espresso. For a plated dessert feel, add a scoop of vanilla or peanut butter ice cream alongside a slice.

It’s also a fun cake to bring to themed parties or candy-lover events—everyone recognizes the classic Snickers flavor, but few have tried it in cake form.

Nutritional & Health Notes

This is a treat, through and through. But it’s made from real, high-quality ingredients that taste infinitely better than processed versions. Each slice is rich, satisfying, and filled with flavor, which means you don’t need a large piece to feel completely indulged.

Peanuts offer healthy fats and protein, while the cocoa provides antioxidants. Still, this is best enjoyed mindfully, perhaps balanced with a lighter meal beforehand.

For those with dietary needs, you can easily adapt the recipe with gluten-free flour, dairy-free cream, and nut-free fillings using the substitutions above.

FAQs

Can I make Chocolate Snickers Cake ahead of time?
Yes! You can bake the cake layers 1–2 days ahead and wrap them tightly. The assembled cake keeps well in the fridge for up to 4 days. The flavors actually deepen over time.

Can I freeze the cake?
Absolutely. Freeze the individual cake layers (before assembling) tightly wrapped. The assembled cake can be frozen as well—slice first, then freeze the pieces individually for easier serving later.

What can I use instead of marshmallow crème?
You can melt 1½ cups mini marshmallows with 1 tablespoon milk in the microwave. Stir until smooth and let cool before combining with peanut butter and sugar for the nougat.

Can I make it in a 9×13 pan instead of layers?
Yes, the cake batter works well in a 9×13 pan. Bake for 35–38 minutes. Layer the nougat, caramel, and ganache right on top once cooled.

Is this cake very sweet?
It’s rich and sweet, but the peanuts and bittersweet chocolate in the ganache help balance it. You can also reduce the sugar slightly in the cake or choose darker chocolate to adjust the sweetness.

Can I use store-bought caramel?
Definitely. A thick, salted caramel sauce works best. If it’s too runny, simmer it briefly to reduce before using.

How do I get clean slices?
Use a sharp knife dipped in hot water and wiped dry between slices. This helps cut through the layers cleanly, especially the ganache.
