The fun part about making a decadent cake like this is that there is no wrong way to eat it.
Triple Chocolate Cake
The secret to this mouthwatering triple layer chocolate cake is espresso powder!
When mixed with water and added to the batter, it creates an incredibly moist texture that melts in your mouth.
Don’t worry, it simply enhances the chocolate flavor – your dessert won’t taste like coffee at all.

Triple Chocolate Cake Recipe Tips and Tricks
- Use room temperature ingredients. This goes for both the batter and the frosting!
The ingredients will combine together much easier, and there won’t be any lumps.
- Don’t have buttermilk? Easily make your own in minutes! Whisk 1 tablespoon of lemon juice or vinegar into 1 cup of regular milk, then let it sit for 5 to 10 minutes.
Once thickened and curdled, use as directed.
- Line your pans. Adding a round of parchment paper to the bottom of your round pans will ensure that your cakes release easily.
- Keep it chilled. Since there is cream cheese in the frosting, store your triple chocolate cake (including any leftovers!) in the refrigerator.
Cover or transfer to an airtight container and enjoy within 3 to 5 days.
- Tip for slicing: Run a large, sharp knife under hot water, then dry completely.
The warm blade will glide easily through your triple chocolate layer cake for perfect, clean slices.
Decorate Like A Pro!
First, let those cake layers cool. I know it will be tempting to get it all assembled, but warm cake will crumble — and melt your frosting!
Allow your cakes to cool for at least an hour at room temperature, but longer is better. You can also pop them in the refrigerator to speed up the process.
Before stacking this triple layer chocolate cake, add a small dab of frosting to your stand or cardboard round.
This will hold the bottom layer in place so it doesn’t slide around.
Then, use a large piping bag to evenly apply the frosting before smoothing it with an offset spatula. It works in between the layers and the outside of the dessert as well!
Triple Chocolate Cake FAQ
I recommend using baking strips – soak them in water and wrap them around the outside of each pan to help the batter rise evenly.
You may need to increase the baking time by about 10 minutes or so. Just keep an eye on the cakes and test them with a toothpick towards the end. Once it comes out clean (without any crumbs), they are done!
If you don’t want to use strips for this triple chocolate cake recipe, simply slice the top off of any domed cakes to make them even.
Brew a strong pot of coffee, then replace the espresso powder and water mixture with one cup of coffee instead.
It might be super tempting to frost the layers of moist chocolate cake quickly so that you can eat this decadent dessert, but you do need to wait to let it cool. I would give it at least 25-30 minutes, at a minimum, before you start adding the frosting to the top of the cake, the laters, or the sides.
If you start applying the creamy chocolate buttercream frosting too soon, you’re going to have a cake covered in melted chocolate frosting, which will still be flavorful, but it won’t be nice and pretty to look at.
For the best results, give the cake plenty of time to cool down to room temperature before you start adding any frosting to the cake.
You can use a frosting knife or just use the back of a knife to add the frosting. You do have to be careful applying it to baked cakes and be sure that you add quite a bit to spread out evenly over the layers, sides, and top.
You are going to frost the sides of the cake last so that you can make sure that you can have the layers covered as well as the top. Then scrape the sides of the large bowl so that you get all the frosting off, and spread that over the cake evenly. This is the best way to make sure that you don’t leave a small amount in the bowl – as every portion of frosting should be used.
Yes! To freeze an entire cake, place it in the freezer until it hardens (about 1 ½ to 2 hours). Then, wrap tightly in a layer of plastic wrap and another layer of aluminum foil.
Or, freeze individual slices on a plate or sheet pan for about an hour before wrapping in plastic and foil.
Store your triple chocolate layer cake for up to 3 months in the freezer and thaw in the refrigerator before serving.
With love, from our simple kitchen to yours.
