How to Make Snickers Bar Layer Cake with Peanut Butter Frosting

Step 1: Bake the Chocolate Cake Layers

Start by preheating your oven to 350°F (175°C) and preparing two 8-inch cake pans with grease and parchment paper. Whisk together the dry ingredients — flour, sugar, cocoa powder, baking soda, baking powder, and salt — in one bowl. In another bowl, beat the eggs, buttermilk, vegetable oil, and vanilla extract until combined. Slowly mix the wet ingredients into the dry, then carefully stir in the hot water or coffee to smooth out the batter. Divide the batter evenly between the pans and bake for 30–35 minutes, or until a toothpick comes out clean. Once baked, let the cakes cool completely before slicing each layer in half horizontally to create four cake rounds. This multi-layer approach ensures your cake will have that perfect stacked look and balance of frosting.

Step 2: Make the Peanut Butter Frosting

Using softened unsalted butter and smooth peanut butter, beat them together until the mixture is light and fluffy — this sets the stage for a luscious frosting. Gradually add sifted powdered sugar, along with vanilla extract and heavy cream or milk, slowly increasing the liquid until the frosting reaches a creamy, spreadable consistency. The frosting should be rich but smooth enough to coat each cake layer evenly and help anchor those delicious fillings.

Step 3: Assemble the Cake

Place the first cake layer onto your serving plate and spread a generous layer of peanut butter frosting. Drizzle caramel sauce over the frosting, then sprinkle a handful of chopped salted peanuts along with chunks of Snickers bars for that iconic candy bar crunch. Repeat this for the remaining layers, stacking carefully for an even, towering effect. Finish by spreading the rest of the peanut butter frosting around the entire cake, smoothing out the sides and top with a spatula for a polished look.

Step 4: Decorate

Warm the caramel sauce slightly so it flows easily, then drip it gently over the edges of the cake for that irresistible caramel cascade. Use some of the peanut butter frosting to pipe elegant swirls or rosettes around the top edge of the cake. Add larger Snickers bar pieces on top to give an extravagant finishing touch, and press mini chocolate chips around the base to create a delightful decorative border. Place the cake in the refrigerator to chill and set before slicing and serving — this helps the layers firm up beautifully.

Make Ahead and Storage

Storing Leftovers

After enjoying your Snickers Bar Layer Cake with Peanut Butter Frosting, store any leftovers covered tightly in the refrigerator. The cake will stay fresh for up to 4 days, allowing you to savor each delicious bite slowly without sacrificing flavor or texture.

Freezing

If you want to make this cake ahead of time or save some for later, it freezes wonderfully. Wrap the whole cake or individual layers tightly in plastic wrap and aluminum foil to prevent freezer burn. Freeze for up to 3 months. When ready, thaw in the refrigerator overnight before frosting or serving.

Reheating

This cake is best enjoyed chilled or at room temperature, but if you prefer a slightly warmed slice, microwave briefly in short bursts at low power. Be careful not to overheat, or the frosting and caramel may become too runny.

FAQs

Can I substitute the peanuts for another nut in the Snickers Bar Layer Cake with Peanut Butter Frosting?

Absolutely! While salted roasted peanuts provide that classic Snickers crunch, you can swap them with chopped almonds, pecans, or even cashews based on your preference or dietary needs. Just keep in mind it will alter the flavor profile slightly.

Is it possible to make this cake gluten-free?

Yes, by using a 1-to-1 gluten-free all-purpose flour blend in place of regular flour, you can still achieve a delicious and moist cake. Make sure your cocoa powder and baking powder are also gluten-free certified for best results.

Can I use natural peanut butter for the frosting?

Natural peanut butter tends to be thinner and less stable than smooth commercial varieties, which might affect the consistency of your frosting. If using natural peanut butter, consider chilling the frosting before spreading to help it firm up.

How do I make homemade caramel sauce for the filling and topping?

Homemade caramel is simple and delicious! Just melt sugar until golden brown, then stir in heavy cream and butter. Cook until smooth and slightly thickened. There are many great recipes available if you want to skip store-bought.

Can I prepare parts of the Snickers Bar Layer Cake with Peanut Butter Frosting in advance?

Definitely! Baking the cake layers and making the frosting can be done a day ahead. You can also assemble the cake fully and refrigerate overnight, which helps flavors meld beautifully and makes serving easier on the day of your event.
