Key Cake Ingredients
- Butter– use unsalted butter for this recipe.
- Water– if you want to intensify the chocolate flavor, you can use coffee instead of water.
- Unsweetened cocoa powder– sift or whisk if there are big clumps before using.
- Eggs– make sure the eggs are at room temperature, this will help the cake rise.
- Sour Cream– the sour cream makes the cake super rich and super moist! Use full-fat sour cream for best results. There is also sour cream in the chocolate frosting which makes it super smooth and decadent.
How to Make Easy Chocolate Cake
(For the full recipe with ingredients and instructions, scroll down to the bottom of the post).
- Preheat the oven. Grease a 9×13-inch pan. Set aside.
- Make the butter cocoa mixture. In a small saucepan, combine the butter, water, cocoa powder, and salt and place over medium heat. Cook, stirring with a spatula, just until melted and combined. Remove from the heat and set aside.
- Combine wet and dry ingredients. In a large bowl, whisk together the flour, sugar, and baking soda. Add half of the melted butter cocoa mixture and whisk until completely blended. The mixture will be thick. Add the remaining butter mixture and stir until combined.
- Add the eggs, sour cream, and vanilla. Whisk until smooth.
- Bake the cake. Pour the batter into the greased pan and bake for 25 to 30 minutes, or until a toothpick inserted into the center of the cake comes out clean.
- Cool. Let the cake cool completely before frosting.
- Make the frosting. In a large bowl, sift together the powdered sugar and cocoa powder. In the bowl of a stand mixer, beat the butter until smooth, about 1 minute. Scrape down the sides of the bowl with a spatula and add the powdered sugar, cocoa, sour cream, vanilla, and salt. Beat until frosting is smooth, this will take about 3 minutes. If you need to scrape down the sides, do so, and mix again. The frosting will be smooth and silky! It’s the BEST!
- Frost and serve. Use a butter knife or an offset spatula to frost the cooled cake. Feel free to add sprinkles or any decorations you wish! Cut into squares and serve.
Storing Tips
- Storing in the Refrigerator: Because of the sour cream in the cake and frosting, I store the cake in the refrigerator. Cover tightly and store for up to 5 days. Let it come to room temperature before serving. Although, I do love a cold slice right out of the fridge:)
- Freezing: You can make the cake in advance and freeze the cake. Let it cool completely. Carefully wrap the cake in plastic wrap and foil. Place in the freezer and freeze for up to 3 months. Thaw and frost with chocolate buttercream.

This cake literally looks like it’s a party in your mouth!
Loving how 1. this is a sheet pan cake and 2. how moist and rich it looks! Not a fan of dry cakes and this looks AMAZING ๐
Can I use GF flour?
I haven’t tried it. If you do an all purpose gf flour it should be fine though!
Looks amazing! For the cake, is it OK to use Dutch process cocoa?
Hi. My daughter and I made this cake this weekend and we put it in a 9×13 like the recipe said but it was much higher than yours. At the risk of sounding like I haven’t a clue (which maybe I don’t!), was this supposed to go in a bigger sheet pan? In the pictures yours look more like cake type brownies for a height and mine went almost up to the top of a 9×13 pan. Just thought I would check. The house smells AMAZING! Thanks for all your great recipes!!!

Hi Laurie-I make this cake in a normal 9×13 pan. If you want a think cake, you could probably do it in a jelly roll pan, but it will be a lot thinner.
How do you store this cake? Refrigerator or counter? Thanks!! I just made it and itโs so yummy!!ย
I store it on the counter, covered. I am so glad you like it!
I made this cake twice already with my two little grandchildren, ages 3 and 5. They love baking and I love having them help me. Thank you for an easy, fun, delicious recipe! (Of course I didn’t take a picture = lame)
Yummy cake with beautiful toppings, it looks so divine.
I am a baker and a mom, i make Designer Cakes in Delhi, India, and can promise any and everyone that this chocolate cake is a recipe for keeps. i am going to make all our recipes for sure ๐
Thanks for sharing
So happy you liked the cake!
Can you make these as cupcakes?
Yes! Just reduce the baking time.
In your recipe directions you suggest using a whisk to combine the ingredients. Why not use a hand mixer?
This is a really very easy recipe and I am going to make it today. I love such moist cake and will update you after I bake it.
I’m all over a simple chocolate cake for picnics and weekend snacking in the summer.
Looks so good!
Your chocolate cake with rainbow sprinkles needs clarification. The recipe says to pour into a prepared 9×13 pan, but you say above that that it’s great because it’s a sheet cake. ย Which is is? ย I made it and did the 9×13, but the cook time was off and it didn’t look like yours…..bummer to spend the time and ingredients when the recipe is confusing.
The recipe is written for 9×13 pan.
This is the second time im baking this cake ! Itโs absoluty delicious!! I will only make this chocolate cake from this Day forth ! Wonderful cake !!ย
I have made this recipe at least TEN times since seeing it on your website! My husband is obsessed and my grandchildren love it, too. You can’t go wrong if you add 1 cup of mini chocolate chips and bake for about 5 minutes more. YUM!
So happy you like the cake! Love the chocolate chip addition!
Easy, beautiful cake. I did not have cocoa, so I doubled the vanilla and added 1 T orange liquer.
Of course, I concocted an orange glaze to top it off.
great and love chocolate cakes
What flour can I use instead of all-purpose flour?
My cake was quite a bit paler than the one in this pics. I’m wondering whether 1/3 c cocoa was correct. Should it be 1 1/3? ย The texture was nice, but aside from lacking much chocolate flavor, it was too sweet, even after cutting back the sugar to 1 1/2 c.ย
This is my go to chocolate cake as it is so simple to make and perfect for any occasion. I live in Spain where sour cream does not exist, so I substitute yogurt and have not had any issues- cake and frosting are perfect. I’ve used the recipe to make cupcakes, 9×19, 9×9, etc. It is so versatile!
Yep, this is the easiest and the best chocolate cake that everyone enjoys. You are so right, Maria!
Would this be too crumbly to make as a regular round cake with frosting?
It is a very moist cake, it should be fine!
Can this cake be frozen? I’d like to bring it to a pot luck but would prefer to make ahead of time.
Did you try to freeze this? I know this is an old post and you may not remember ๐ wanting to make it for my sons birthday party and so as much ahead of time as possible:
Can I use this as a Christmas log cake? I wonder if itโs going to be too soft to to fold and crumbly.
I am not sure, sorry! I’ve never tried it!
Is this enough batter to make a 2 layer roundcake? I’m looking for a chocolate cake recipe to use in a strawberry shortcake.
Yummm this looks amazing!! love me some easy recipes!
stay safe!

What can I substitute for sour cream?
Plain Greek yogurt
This is a really very easy chocolate cake recipe and I am going to make it today. I think It is so so Delicious.

Hey there! Can I replace sour cream with yoghurt? Also, do I need to store this in the fridge?
Yes!
Ugh! Wanted to make this cake sooooo bad! I have no sour cream or yogurt! Is there any other substitute I could use for the sour cream? Currently on a stay at home order and can’t go shopping. Any advice would be soooo appreciated!
Thanks in advance!
Do you have to allow the cocoa mixture to cool before adding into the dry ingridients?
Hi Maria! I made this cake for my family to enjoy on Valentineโs Day and we LOVED it!! So moist and delicious! Thanks for sharing your recipes! I enjoy making them ๐
Iโve made the chocolate bundt cake and got great reviews on it. How do I modify this recipe to make 3 10 inch round cakes?
Hi! The water-butter-cocoa mixture will be still quite warm/hot when you mix into the flour, or should it have cooled down completely before adding to flour? Thanks!
It doesn’t need to be completely cool.
Several of our friends ask us to bring this cake every time we get together for dinner or a potluck. Everyone LOVES this cake!
Has anyone tried this as layer cake!? If so how did it turn out and what adjustments would I make !?
I am sure it will work, just adjust the baking time. Times will vary depending on what pans you use.
Where are the amounts for the ingredients listed?
Scroll to the bottom of the post and look in the recipe card.
Made it last night! Itโs insanely good!! A very easy method and turned out better than I even anticipated. I will definitely make it again.
Glad you loved the cake!
Did you use parchment paper to lift your cake out of the pan? It looks like it has been removed for the pictures.
Just made this cake; it turned out amazing, moist and yummy – followed the recipe exactly as written, used a 9 x 12 glass Pyrex dish – Frosting is delicious as well! Perfection, thanks for sharing this recipe!
It is so good! Glad you loved it!
I made this today for our Valentine’s dinner. WOW!!!!! Delicious!!
I am so glad you love the cake!
We all loved this cake . Very simple to make and delicious to eat. Thanks!
I have made this cake for two birthdays. Every ne loved it. It is now the top requested cake. I decorated cakes for a living. I frosting is delicious. Awinnerr
I love this!
After you bake it, do you flatten it or level it somehow? My cake puffed up pretty high.
I don’t. It rises up in the oven, but should’t be “puffy.”
