Why You'll Love This Triple Chocolate Cake
- After seeing how easy it is to make this triple chocolate cake, you’ll never need a box mix again!
- Since this is an oil based cake, it is extra moist!
- You don’t need any fancy ingredients for this triple chocolate cake! I bet you’ve got everything you need already in your kitchen.
- This moist chocolate cake is covered in an ultra rich chocolate frosting.
- You can easily make this chocolate cake dairy free, so it’s perfect for those with food allergies.
Ingredients Needed

- Chocolate Chips: I recommend using mini chocolate chips. Since they’re smaller they won’t all fall to the bottom of the cake, plus mini chocolate chips are much more pleasant to bite into.
- Milk: you can use whole milk or a dairy free milk of your choice if you’re dairy-free. This recipe has been tested both ways.
- Butter: feel free to use regular butter or vegan butter if you’re dairy free.
- Cocoa Powder: I recommend using dutch processed cocoa powder in this recipe.
- Shortening: if you’re using vegan butter in the frosting, I recommend combining it with some shortening.
Step by Step Instructions
Note: Full ingredient measurements and instructions can be found in the recipe card at the bottom of this page.

Step 1: Preheat your oven to 350°Fahrenheit and line three 8 inch round cake pans with parchment paper. Spray each one with nonstick spray then line the bottoms of the pans. Set aside.
Step 2: In a large bowl, whisk together the flour, sugar, cocoa powder, salt, baking powder and baking soda together.
Step 3: Add in the eggs, vanilla extract, milk, oil and hot water into the dry ingredients and mix until smooth. Stir in the mini chocolate chips.
Step 4: Divide the chocolate cake batter between the 3 cake pans and bake for 20-26 minutes. You’ll know they’re done when a toothpick inserted in the middle of the cake comes out clean with no crumbs.
Step 5: Let the cakes cool in the pan for about 20 minutes, then remove and cool completely on a wire cooling rack.
Step 6: Once the cakes are cool you can make the buttercream. In the bowl of a stand mixer or in a large bowl with a hand mixer, beat the butter (and shortening, if using) together until smooth. Add the cocoa powder and beat together.
Step 7: Add the vanilla extract and the icing sugar, ¼ cup at a time until it’s the consistency you like.
If you think the buttercream is too thick, you can add 1 tablespoon of milk at a time until it’s the consistency you want. If the chocolate frosting gets too thin, add ¼ cup of confectioners’ sugar at a time.
Step 8: Assemble the cake! Place the first cake layer on a cake plate and place some of the chocolate frosting on top and smooth it over.
Repeat this once more, then place the final cake on top and frost the sides and top of the cake. Decorate as you wish!
FAQs and Expert Tips
The mini chocolate chips might sink while baking, but once you assemble the cake it just means you’ll get chocolate chips in every bite!
No, feel free to leave them out and then you’ll have a triple layer chocolate cake instead!
Yes you can, but just note that the cake layers will be thinner and they won’t need as much time in the oven.

Expert Tips
- I recommend using a weighing scale when you’re baking! It is so easy to add too much flour or cocoa powder if you’re using measuring cups, and that’ll lead to a dry cake. If you don’t have a weighing scale, make sure you use the scoop and level method. Use a fork to fluff up the flour, then use a spoon to spoon the flour into the measuring cup. Run the back of a knife along the top of the cup so it’s even. Make sure you also do this for the cocoa powder!
- You should always grease and line your cake pans with parchment paper when baking a cake. If you don’t do this, your cake might stick to the pans and fall apart.
- Let the cake layers completely cool before you frost them, otherwise the frosting might slide off!
- The frosting recipe makes enough buttercream to frost the cake like in my pictures. If you want to pipe more frosting on the cake or want a thicker layer of frosting, you’ll need to multiply the frosting ingredients by 0.5
Storage and Freezing Instructions
Store the assembled cake in a cake carrier or airtight container at room temperature for 3-4 days.
To freeze the cake layers, let them cool completely and tightly wrap in plastic wrap and then foil. Freeze in ziploc bags for up to 3 months and let them thaw at room temperature when ready to use.
Any leftover buttercream can be stored in an airtight container in the freezer for up to 2 months. Let it thaw in the fridge and then whip with a handheld mixer or stand mixer before using.
