Chocolate cake is the ULTIMATE dessert for any occasion and this is the BEST Easy Chocolate Cake Recipe. The cake only takes 25-30 minutes to bake, depending on your oven and the chocolate sour cream frosting is easy to whip up!

It is made in a basic 9×13-inch pan and that means no chilling cake layers or decorating cake layers. You don’t need to do a crumb coat of frosting, you pour the cake batter in the sheet pan, bake, and top with chocolate frosting. It is SO simple!

It is easy to take to parties, picnics, and potlucks. The cake is easy to cut into squares and serve, and it feeds a crowd!

It’s the perfect dessert for birthdays, holidays, or just because you are craving chocolate!

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
  • Kosher salt
  • All-purpose flour
  • Granulated sugar
  • Baking soda
  • Eggs– at room temperature
  • Sour Cream– the sour cream makes the cake super rich and super moist! Use full-fat sour cream for best results.
  • Vanilla extract

Chocolate Frosting Ingredients

This is the BEST chocolate frosting. I use sour cream in the cake AND the frosting.

The addition of sour cream to chocolate frosting makes the frosting super silky and smooth and it’s not overly sweet, making it the perfect frosting for the chocolate cake. It’s perfection!

  • Confectioner’s sugar
  • Unsweetened cocoa powder
  • Unsalted butter
  • Sour Cream
  • Vanilla extract
  • Pinch of salt

How to Make Easy Chocolate Cake

(For the full recipe with ingredients and instructions, scroll down to the bottom of the post).

  • Preheat oven and grease a 9×13-inch pan. Set aside.
  • 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.
  • 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, one at a time, whisking until completely blended. Add the sour cream and vanilla extract and whisk until smooth.
  • Pour the cake batter into the prepared pan and bake until a toothpick inserted into the center of the cake comes out clean, 25-30 minutes. Let the cake cool completely before frosting.

  • While the cake is cooling, 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 and add the sifted powdered sugar and cocoa, sour cream, vanilla, and salt. Beat until frosting is smooth, about 3 minutes. If you need to scrape down the sides, do so, and mix again.
  • Frost the cooled chocolate cake with the chocolate sour cream frosting. Cut cake into squares and serve.

How to Store

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:)

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.

  1. 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 🙂

    1. I haven’t tried it. If you do an all purpose gf flour it should be fine though!

  2. 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!!!

    1. 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.

  3. 5 stars
    How do you store this cake? Refrigerator or counter? Thanks!! I just made it and it’s so yummy!! 

  4. 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)

  5. 5 stars
    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 🙂
    Thanks for sharing

  6. In your recipe directions you suggest using a whisk to combine the ingredients. Why not use a hand mixer?

  7. 5 stars
    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.

  8. I’m all over a simple chocolate cake for picnics and weekend snacking in the summer.

    Looks so good!

  9. 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.  Which is is?  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.

  10. This is the second time im baking this cake ! It’s absoluty delicious!! I will only make this chocolate cake from this Day forth ! Wonderful cake !! 

  11. 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!

  12. 5 stars
    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.

  13. 2 stars
    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?  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. 

  14. 5 stars
    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!

  15. 5 stars
    Yep, this is the easiest and the best chocolate cake that everyone enjoys. You are so right, Maria!

  16. Can this cake be frozen? I’d like to bring it to a pot luck but would prefer to make ahead of time.

    1. Did you try to freeze this? I know this is an old post and you may not remember 🙂 wanting to make it for my sons birthday party and so as much ahead of time as possible:

  17. Is this enough batter to make a 2 layer roundcake? I’m looking for a chocolate cake recipe to use in a strawberry shortcake.

  18. 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!

  19. Hi Maria! I made this cake for my family to enjoy on Valentine’s Day and we LOVED it!! So moist and delicious! Thanks for sharing your recipes! I enjoy making them 🙂

  20. I’ve made the chocolate bundt cake and got great reviews on it. How do I modify this recipe to make 3 10 inch round cakes?

  21. 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!

  22. 5 stars
    Several of our friends ask us to bring this cake every time we get together for dinner or a potluck. Everyone LOVES this cake!

  23. Has anyone tried this as layer cake!? If so how did it turn out and what adjustments would I make !?

    1. I am sure it will work, just adjust the baking time. Times will vary depending on what pans you use.

  24. 5 stars
    Made it last night! It’s insanely good!! A very easy method and turned out better than I even anticipated. I will definitely make it again.

  25. 5 stars
    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!
