Yes, that’s right, you can make your chocolate cake and your icing with ease. There’s nothing to it, even if it’s your first time making icing.

Grab a spoon and get ready to swoon. You’re going to want to make a batch just so you can eat it from a bowl to satisfy those chocolaty cravings. Or maybe that’s just me? I can’t be the only one, can I?

An Easy Recipe for Great Chocolate Icing

Everyone needs an easy recipe for homemade chocolate frosting.

I know the store-bought stuff is convenient, but when you get a taste of this yummy chocolate frosting, you will never again buy that other stuff.

It’s made with just four simple ingredients, and as much frosting as that will make, you may want to make a little more just to have leftover frosting.

I promise it’s worth it. My husband came into the kitchen the other day while I was taste-testing my easy frosting recipe here.

He grabbed a spoon, and well before we knew it, it was gone. I had to make more while my chocolate Bundt cake cooled, but it’s so simple.

It’s ready in minutes. I guess what I’m trying to say here is this, watch out for the allure of this creamy chocolate frosting.

If you can’t resist frosting, make more than you need because you will absolutely scrape up every last bit and lick your spoon clean.

Easy Chocolate Frosting Recipe

I know I’ve already mentioned it twice, but again, I just want to make it clear that this homemade chocolate frosting only requires four ingredients.

While most homemade frosting recipes don’t often have gobs of ingredients, this one is perhaps the easiest because there is no butter.

So, if you’re trying to frost a cake and you don’t have butter to make the best chocolate buttercream frosting, all you need here is powdered sugar (also known as confectioners’ sugar), unsweetened cocoa powder, vanilla extract, and buttermilk.

Now, I say buttermilk like everyone has this in their kitchen, but don’t worry if you don’t have any.

You will see in the full recipe below that you can use regular milk instead. All you do is add everything to the bowl and mix, and then you have chocolate icing! It’s that easy! 

These basic ingredients make for a reliable and utterly delicious frosting for any cake. And as always, remember to only frost a cooled cake, or you’ll wind up with a runny frosting mess on your hands. 

How To Make The Icing

  1. Add the powdered sugar to a medium bowl.
  2. Next, add the unsweetened cocoa, buttermilk, and vanilla extract and mix well.
  3. Pour over your dessert.

How To Store The Chocolate Icing

The recipe doesn’t make a lot of icing, but if you do have some leftover, you will want to store it in an airtight container and place in the refrigerator.

You will need to add more buttermilk to thin it out when you want to use it again.

Do I Need A Pastry Bag?

No, you don’t need a pastry bag. This is not thick icing. I usually put the icing in a glass measuring cup and pour it over the dessert of my choice.

Can I Use This Frosting On Sheet Cake?

Definitely! But, you will most likely want to double or triple the recipe, depending on the size of your cake.

This has to use more than 1/4 cup sugar, could that be a misprint?
